Przewlekły zespół kompartmentowy wywołany wysiłkiem
Etiologia i przyczyny

Przewlekły zespół ciasnoty przedziałów powięziowych wysiłkowy (CECS) to schorzenie charakteryzujące się wzrostem ciśnienia w przedziałach mięśniowo-powięziowych podczas wysiłku, prowadzącym do upośledzenia perfuzji i niedokrwienia tkanek. Patofizjologia CECS jest wieloczynnikowa, obejmując przerost mięśni (do 20% powiększenia objętości), niepodatność powięzi, zmniejszony powrót żylny oraz mikrourazy. Diagnostyka opiera się na pomiarze ciśnienia wewnątrzprzedziałowego, gdzie wartości diagnostyczne dla kończyn dolnych to: ciśnienie przed wysiłkiem ≥ 15 mmHg, 1 minutę po wysiłku ≥ 30 mmHg oraz 5 minut po wysiłku ≥ 20 mmHg. CECS najczęściej dotyczy przedziału przedniego goleni, ale może występować także w innych lokalizacjach, takich jak przedramię czy udo. Grupy ryzyka to młodzi sportowcy, rekruci wojskowi oraz osoby intensywnie trenujące, a czynniki ryzyka obejmują m.in. nieprawidłową technikę treningu, zaburzenia osi kończyn oraz stosowanie sterydów anabolicznych i suplementów kreatyny.

Etiologia przewlekłego zespołu ciasnoty przedziałów powięziowych wysiłkowego

Przewlekły zespół ciasnoty przedziałów powięziowych wysiłkowy (Chronic Exertional Compartment Syndrome, CECS) to stan charakteryzujący się nawracającymi, odwracalnymi epizodami niedokrwienia po zaprzestaniu aktywności, co prowadzi do przewidywalnego zmniejszenia ciśnienia w przedziale powięziowym. Chociaż dokładna patofizjologia CECS nie jest w pełni poznana, uważa się, że etiologia ma charakter wieloczynnikowy.12

Podstawowy mechanizm patofizjologiczny

Główny mechanizm powstawania CECS związany jest ze zwiększeniem ciśnienia w jednym lub wielu przedziałach mięśniowo-powięziowych podczas wysiłku fizycznego. Podczas ćwiczeń określone przedziały mięśniowe powiększają się nawet o 20% w wyniku zwiększonego przepływu krwi i objętości płynów. Gdy objętość i ciśnienie osiągają poziom, który przewyższa ciśnienie perfuzji naczyń włosowatych, dochodzi do upośledzenia dopływu krwi i niedotlenienia tkanek.123

Podczas wysiłku fizycznego dochodzi do wzrostu przepływu krwi do pracujących mięśni, co powoduje ich powiększenie. W przypadku CECS, otaczająca mięśnie powięź (fascia) jest niepodatna i nie rozszerza się adekwatnie do powiększających się mięśni, co powoduje wzrost ciśnienia w przedziale i w konsekwencji zaburzenie perfuzji tkanek.45 Wiele badań wykazało zmniejszony przepływ krwi i obniżone utlenowanie w kończynach dolnych u pacjentów z objawowym CECS.3

Czynniki przyczyniające się do rozwoju CECS

Istnieje kilka czynników, które mogą przyczyniać się do rozwoju przewlekłego zespołu ciasnoty przedziałów powięziowych wysiłkowego:

  • Przerost mięśni podczas ćwiczeń, który nie jest kompensowany przez odpowiednie rozszerzenie powięzi26
  • Zmniejszony powrót żylny prowadzący do zastoju krwi26
  • Mikrourazy tkanek prowadzące do degeneracji tkanek lub tworzenia blizn12
  • Miopatie powodujące zaburzenia funkcji mięśni26
  • Niepodatna powięź, która ogranicza prawidłowe rozszerzanie się przedziału mięśniowego26

Czynniki anatomiczne i mechaniczne

Do czynników anatomicznych i mechanicznych przyczyniających się do rozwoju CECS można zaliczyć:

  • Nieprawidłowa technika treningu lub nadmierna częstotliwość ćwiczeń27
  • Zaburzenia osi kończyn i nieprawidłowe ustawienie26
  • Różnica długości kończyn dolnych2
  • Technika biegania wpływająca na obciążenie przedziałów mięśniowych24
  • Nieprawidłowa kontrola mięśniowa i nieskoordynowane ruchy2
  • Nieprawidłowa biomechanika stóp (np. stopa płaska lub pronująca)8
  • Napięcie mięśni łydki (mięśnia brzuchatego łydki i/lub mięśnia płaszczkowatego)8
  • Słabe mięśnie stabilizujące biodro8

Czynniki wyzwalające i ryzyka

CECS występuje najczęściej u osób wykonujących powtarzalne czynności ruchowe, takie jak:19

  • Bieganie – najbardziej typowa aktywność związana z CECS10
  • Taniec
  • Łyżwiarstwo szybkie
  • Musztra wojskowa
  • Pływanie
  • Kolarstwo
  • Wioślarstwo (szczególnie w przypadku CECS górnych kończyn)6

Grupami szczególnie narażonymi na rozwój CECS są:10

  • Młodzi sportowcy (zwłaszcza osoby poniżej 30 roku życia)1112
  • Rekruci wojskowi13
  • Sportowcy wytrzymałościowi
  • Osoby intensywnie trenujące lub przetrenowane11

Rola czynników farmakologicznych i suplementów

Niektóre substancje farmakologiczne i suplementy mogą zwiększać ryzyko rozwoju CECS:

  • Stosowanie sterydów anabolicznych – może powodować szybki przerost mięśni, który nie jest kompensowany przez rozszerzenie powięzi141516
  • Suplementacja kreatyną – może powodować obrzęk mięśni i zwiększać ciśnienie w przedziale141713

Nowe teorie dotyczące etiologii

Najnowsze badania sugerują, że mechanizmem leżącym u podstaw rozwoju CECS może być niedrożność odpływu żylnego związana z czynnościowym uciskiem mięśniowym. Zgodnie z tą teorią, ucisk naczyń żylnych przez przerośnięte mięśnie podczas wysiłku prowadzi do zastoju krwi i zwiększenia ciśnienia w przedziale mięśniowym.1813

Inna teoria sugeruje, że dysfunkcje odcinka lędźwiowego kręgosłupa (często z minimalnymi lub nieobecnymi objawami lędźwiowymi) mogą zaburzać odruchowe hamowanie antagonistycznego działania mięśni podczas fazy obciążenia i końcowej fazy podporowej cyklu chodu/biegu.8

Najczęściej dotknięte przedziały mięśniowe

CECS najczęściej występuje w kończynach dolnych, szczególnie w obszarze podudzia, ale może również dotyczyć innych lokalizacji:1920

  • Przedział przedni goleni – najczęstsza lokalizacja2122
  • Przedział boczny goleni
  • Przedział tylny głęboki goleni
  • Przedział tylny powierzchowny goleni
  • Przedramię (szczególnie u zawodników sportów rzutowych i wioślarzy)23
  • Stopa
  • Udo
  • Pośladek24

Obraz kliniczny i diagnostyka

CECS charakteryzuje się typowym obrazem klinicznym, który pomaga w rozpoznaniu tego schorzenia. Pacjenci zgłaszają ból o charakterze tępym lub kurczowym, który pojawia się podczas wysiłku fizycznego i narasta w miarę kontynuowania aktywności. Objawy zwykle ustępują po odpoczynku, co jest cechą charakterystyczną odróżniającą CECS od ostrego zespołu ciasnoty przedziałów powięziowych.1721

Złotym standardem diagnostycznym jest pomiar ciśnienia wewnątrzprzedziałowego przed i po wysiłku fizycznym. Aby potwierdzić diagnozę CECS, ciśnienie w przynajmniej jednym z przedziałów mięśniowych powinno być podwyższone po wysiłku. Kryteria diagnostyczne dla kończyn dolnych obejmują:66

  • Ciśnienie przed wysiłkiem ≥ 15 mmHg
  • Ciśnienie 1 minutę po wysiłku ≥ 30 mmHg
  • Ciśnienie 5 minut po wysiłku ≥ 20 mmHg

Wystarczy, że jeden z tych pomiarów jest nieprawidłowy, aby potwierdzić diagnozę.6

Leczenie

Leczenie CECS może obejmować metody zachowawcze i chirurgiczne, w zależności od nasilenia objawów i preferencji pacjenta:

Leczenie zachowawcze

Metody zachowawcze mają ograniczoną skuteczność, ale mogą być korzystne we wczesnych stadiach schorzenia:225

  • Modyfikacja aktywności – unikanie lub zmiana ćwiczeń wywołujących objawy
  • Trening techniki biegania (biegacze z przewagą kontaktu tyłostopia mogą skorzystać z treningu biegania przodostopiem)2
  • Fizjoterapia
  • Wkładki ortopedyczne
  • Leki przeciwzapalne
  • Iniekcje toksyny botulinowej (potencjalna metoda leczenia, ale wymagająca dalszych badań)2

Leczenie operacyjne

Jeśli metody zachowawcze nie przynoszą poprawy, leczenie chirurgiczne jest najbardziej skuteczną opcją:2627

  • Fasciotomia – chirurgiczne przecięcie powięzi okalającej dotknięty przedział mięśniowy w celu zmniejszenia ciśnienia. Jest to preferowana metoda leczenia operacyjnego.228
  • Uwolnienie nerwów – procedura wykonywana w celu uwolnienia uciśniętych nerwów, może być przeprowadzana wraz z fasciotomią lub jako oddzielna procedura.26

Wyniki leczenia chirurgicznego są lepsze u młodszych pacjentów oraz u osób poddanych fasciotomii wszystkich zajętych przedziałów mięśniowych.2 Należy jednak zauważyć, że u około 20% pacjentów nie obserwuje się pełnego ustąpienia objawów po fasciotomii, co wskazuje na potrzebę dalszych badań nad mechanizmami odpowiedzialnymi za to schorzenie.2

Podsumowanie etiologii CECS

Przewlekły zespół ciasnoty przedziałów powięziowych wysiłkowy jest schorzeniem o złożonej etiologii, które dotyka głównie młodych sportowców i osoby aktywne fizycznie. Głównym mechanizmem patofizjologicznym jest zwiększenie ciśnienia w przedziałach mięśniowo-powięziowych podczas wysiłku, co prowadzi do upośledzenia przepływu krwi i wystąpienia objawów bólowych.

Choć dokładna patofizjologia CECS nie jest w pełni poznana, czynniki takie jak przerost mięśni, zmniejszony powrót żylny, mikrourazy, niepodatna powięź oraz nieprawidłowa technika treningu mogą przyczyniać się do rozwoju tego schorzenia. Najnowsze badania wskazują również na rolę niedrożności odpływu żylnego jako potencjalnego mechanizmu leżącego u podstaw CECS.

Zrozumienie złożonej etiologii przewlekłego zespołu ciasnoty przedziałów powięziowych wysiłkowego jest kluczowe dla opracowania skutecznych strategii diagnostycznych i terapeutycznych, które pozwolą pacjentom powrócić do pełnej aktywności fizycznej.18

    https://www.ncbi.nlm.nih.gov/books/NBK544284/
    Chronic exertional compartment syndrome (CECS) occurs in the setting of recurrent, reversible ischemic episodes following the cessation of activity resulting in the predictable decrease in fascial compartment pressures. […] Multiple etiologies underlie CECS. During exercise, specific muscle compartments swell up to 20%, secondary to increased blood flow and fluid volume. […] In the setting of CECS, there is ultimately a rise in the pressure within one or multiple musculofascial compartments, which impedes further muscle expansion, eventually compromising blood flow once the volume and pressure reach a level that overrides the capillary perfusion pressure. […] Other etiologies of CECS include various overuse injuries or repetitive mechanisms where tissue degeneration or scar formation occurs as a result of microtrauma. […] Regardless of the exact mechanism, what is known is that the pathology is related to elevated intracompartmental pressures, and it seems to affect those performing repetitive activities, i.e., runners, dancers, speed skaters, and those in military training.

    Chronic exertional compartment syndrome (CECS) is an underdiagnosed condition that causes lower and upper extremity pain in certain at-risk populations. […] CECS is characterized by a reversible increase in pressure within an inelastic fascial compartment leading to compromised tissue perfusion and subsequent pain and neurologic symptoms. […] While the exact pathophysiology leading to increased compartment pressure is not well understood, it is accepted that the cause is likely multifactorial, with muscle hypertrophy, decreased venous return, microtrauma, myopathies and noncompliant fascia playing a role. […] Other factors that have been implicated in playing a role in CECS include improper training, limb malalignment, leg-length discrepancy, running technique, and uncoordinated muscle control.
  • #2 Chronic exertional compartment syndrome: current management strategies
    https://pmc.ncbi.nlm.nih.gov/articles/PMC6537460/
    Despite a lack of consensus on the exact pathophysiology, repetitive exertion of the muscles within a compartment leading to decreased perfusion is accepted as the primary pathway to the onset of symptoms in CECS. […] Nonoperative management has a limited role in the treatment of CECS, but hindfoot runners may benefit from forefoot running training. […] The use of Botox injections may have potential in the treatment of CECS, but more studies are needed to confirm their efficacy. […] Fasciotomy is the preferred operative treatment for both lower-extremity and upper-extremity CECS. […] Improved surgical outcomes are seen in younger patients and those who undergo fasciotomies of all compartments. […] Further research also needs to be done to understand why a large portion (~20%) of the patient population does not experience full resolution of symptoms after fasciotomy.
  • #3 Chronic exertional compartment syndrome – UpToDate
    https://www.uptodate.com/contents/chronic-exertional-compartment-syndrome
    Chronic exertional compartment syndrome (CECS) is a condition that typically affects young endurance athletes, especially those who run extensively. Like acute compartment syndrome (ACS), it is thought to result from increased pressure within a muscle compartment. CECS occurs primarily in the lower leg, although it has been reported in the forearm and elsewhere. […] The pathophysiology of CECS is not completely understood. One theory is that tissue ischemia in CECS stems from a noncompliant fascial compartment that cannot accommodate the expansion of muscle volume that occurs with exercise. Simply put, „stiff” fascia does not allow for the increased blood flow that exercising muscle requires. As pressure increases and local tissue perfusion becomes compromised, metabolic demands cannot be met and ischemic symptoms develop. Several studies have demonstrated decreased blood flow and oxygenation in the legs of symptomatic patients with CECS. […] The role of thicker or stiffer fascia is supported by some studies but refuted by others. However, neither macroscopic nor microscopic assessment of fascial thickness or stiffness has been shown to be a useful predictor of success following fasciotomy.

    Chronic exertional compartment syndrome may respond to nonsurgical treatment and activity modification. […] The cause of chronic exertional compartment syndrome isn’t completely understood. When you exercise, your muscles expand in volume. If you have chronic exertional compartment syndrome, the tissue that encases the affected muscle (fascia) doesn’t expand with the muscle, causing pressure and pain in a compartment of the affected limb. […] Some experts suggest that how you move while exercising might have a role in causing chronic exertional compartment syndrome. Other causes might include having muscles that enlarge excessively during exercise, having an especially inflexible fascia surrounding the affected muscle compartment or having high pressure within your veins.

    The mechanical aggravators of CCS may include: Abnormal foot biomechanics (such as flat or pronated feet). This significantly alters the biomechanical stresses that are placed through the foot and ankle and transmitted to the calf. […] Tightness in the posterior calf muscles (gastrocnemius and/or soleus). This can have the effect of increasing the pressures with other compartments by causing compensatory tightness and overuse. […] Sub-optimal or imbalanced exercise schedules. This can facilitate the continuation and exacerbation of compartment syndrome. […] Weak hip stabilizers. […] Poor footwear. Shoes that do not support the arch or heel can be a significant factor in the manifestation of CCS.

    https://kingsleyphysio.com/common-conditions/chronic-compartment-syndrome/
    Chronic compartment syndrome (CCS) causes a similar build-up of pressures within a given muscle compartment but instead results from the ongoing (chronic) use of a muscle (or muscle group). It is a painful condition that typically affects the calf or shin region during exercise. […] There are 2 broad mechanisms by which chronic compartment syndrome is thought to be caused: The relative increase in tightness and reduction in elasticity of the surrounding fascial tissue. This is due to an increase in fascial fibroblastic activity (cellular proliferation) resulting from repeated or excessive use of a muscle. […] Reduced or poor autonomic control of venous blood return. During high intensity exercise, muscles can physically expand by as much as 20%. […] A third, less substantiated theory, suggests that low-grade lumbar dysfunction (often with negligible or absent lumbar symptoms) may impair reflexive inhibition of antagonistic muscle action during the loading response and terminal stance phases of the gait/running cycle.

    https://orthoinfo.aaos.org/en/diseases–conditions/compartment-syndrome
    Compartment syndrome is a painful condition that occurs when pressure within the muscles builds to dangerous levels. This pressure can decrease blood flow, which prevents nourishment and oxygen from reaching nerve and muscle cells. […] Chronic compartment syndrome, also known as exertional compartment syndrome, is usually not a medical emergency. It is most often caused by athletic exertion and is reversible with rest. […] The pain and swelling of chronic compartment syndrome is caused by exercise. People who participate in activities with repetitive motions, such as running or marching, are more likely to develop chronic compartment syndrome. This is usually relieved by discontinuing the exercise, and is usually not dangerous. […] Chronic compartment syndrome causes pain or cramping during exercise. This pain goes away when activity stops. It most often occurs in the leg.

    When pain in the legs happens during exercise and intensifies as exercise continues, it could be due to chronic exertional compartment syndrome (or CECS), shin splints, stress fractures or various causes of compromise to blood and nerve supply to the leg. […] Compartment syndrome occurs when pressure within muscles builds up, resulting in reduced blood flow and oxygen to the muscles. […] Running is the most common cause of CECS. It is most commonly seen in the young adult population, both elite and recreational runners, other endurance athletes, as well as military recruits. CECS most often occurs in the leg, with the most common areas of compression in the front area around the shin bone, on both the inner and outer aspects. However, CECS can also strike in the upper limbs and thighs. […] CECS is not uncommon, where a few suspected cases are identified each month. However, CECS occurs at varying degrees and is often underdiagnosed due to the delay in seeking medical attention and difficulty in diagnosis.

    Chronic exertional compartment syndrome is one of the most common causes of pain, numbness, and foot drop, most often seen in runners. […] The repetitive impact from running activity is what causes this condition. […] The pain is caused when the fascia, or tissue around the muscle, does not expand with the muscle, causing pressure in that area. […] Chronic compartment syndrome typically occurs in runners who are under 30, although it can occur in people of any age. It is also seen among athletes involved in high intensity exercise or in the presence of overtraining.

    https://forteortho.com/shin-splints-vs-compartment-syndrome-how-to-tell-the-difference/
    Compartment syndrome is a more complex condition often hard to diagnose. It occurs when pressure within a muscle compartment builds up, restricting blood flow and potentially damaging nerves and muscles. Chronic forms of this syndrome, known as chronic exertional compartment syndrome (CECS), are often exercise-induced and affect athletes engaged in repetitive, high-impact activities like running or cycling. […] The condition occurs when the fascia, a non-stretchable tissue surrounding the muscles, cannot accommodate the increased muscle volume during exercise. This results in high pressure within the compartment, restricting oxygen and blood flow. Risk factors include participating in repetitive high-impact sports, overtraining or following intense exercise regimens, and being under 30 years old.

    Lower limb exertional compartment syndrome (LLECS), also known as chronic exertional compartment syndrome (CECS), is an overuse syndrome characterized by exercise-induced elevation of intramuscular pressures (IMP) that results in reproducible transient pain, paresthesias, and neuromuscular dysfunction. […] The exact mechanism that causes exertional compartment syndrome is unknown. The increased intra-compartmental pressures are thought to impede tissue perfusion, create a relative oxygen debt, and result in symptom onset. The exact mechanism by which this occurs remains unclear. […] There are several proposed contributing factors, which vary from noncompliant anatomical tissues to deviations of anatomical features and build-up of metabolic byproducts. It has been recently suggested that venous outflow occlusion may play a significant role in increased compartment pressures and symptom development.

    https://sportsclinicnq.com.au/chronic-exertional-compartment-syndrome-cecs/
    CECS syndrome refers to exercise-induced leg pain resulting from muscle swelling and an increase in pressure in a compartment of the lower leg. […] Factors that may contribute to compartment syndrome include an increase in the size and volume of the muscles within the compartment, unaccustomed strenuous exercise, or progressive tightening of the surrounding connective tissue sleeve. […] A history of severe injury can cause scar tissue or injury to the compartment sleeve. Weight gain can also be associated with increasing compartment pressures. Drugs such as anabolic steroids can cause the muscle to increase in size but the compartment does not increase to accommodate it. Supplements such as creatine might cause swelling of the muscle. Training errors including excessive training frequency, type of exercise and poor running mechanics are also associated with fatigue and swelling of the muscle, increasing compartment pressure.

    Chronic compartment syndrome (CCS) is a recurrent syndrome during exercise or work. CCS is characterized by pain and disability that subside when the precipitating activity is stopped but that return when the activity is resumed. […] The incidence of compartment syndrome depends on the patient population studied and the etiology of the syndrome. […] Any internal or external event that increases pressure within a compartment can cause compartment syndrome. Thus, increased fluid content or decreased compartment size can lead to the condition. […] Increased fluid content can be caused by the following: Intensive muscle use (eg, tetany, vigorous exercise, seizures) […] Everyday exercise activities (eg, stationary bicycle use, horseback riding) […] Burns […] Envenomation […] Decreased serum osmolarity (eg, nephrotic syndrome)

    https://nyulangone.org/conditions/compartment-syndrome/diagnosis
    Chronic compartment syndrome, also called chronic exertional compartment syndrome, occurs as the result of intense workoutsusually high-impact exercises such as running and jumping. […] Exercise increases blood flow to muscles, expanding blood vessels and increasing pressure inside muscle compartments. The pressure may eventually restrict blood flow altogether, damaging the muscles and nerves. […] Chronic compartment syndrome is not immediately dangerous, but it can become a more serious problem if not eventually addressed. Athletes who use anabolic steroids are at increased risk, because muscles may grow quickly and push against the surrounding fascia, increasing the pressure inside the muscle compartment.

    Chronic exertional compartment syndrome (CECS) is one cause of exercise-related lower leg pain. […] During exercise, muscles swell and fluid enters the compartment spaces. However, if the fascial wall of a compartment is too tight, blood flow may be cut off to the nerves and muscles. […] CECS causes a dull or crampy lower leg pain which starts at some point during exercise. […] To confirm that the problem is CECS, the physician will measure the pressure inside the compartments of the lower legs before and after exercise. In CECS, the pressure in at least one of the legs compartments will be higher than expected after exercise. […] If athletes cannot change their exercise routine, or if changing the exercise program does not help, CECS is a condition that can be treated with surgery. […] Creatine use may increase the risk of developing CECS, and discontinuing this over-the-counter supplement may prevent the development of CECS symptoms.

    Investigate the theory that chronic exertional compartment syndrome (CECS) results from venous outflow obstruction due to functional muscular compression. Chronic exertional compartment syndrome results from venous outflow obstruction due to functional muscular compression. Understanding the cause of CECS will allow the development of more precise and successful treatment plans. […] The exact etiology of CECS has not been clearly identified, but magnetic resonance imaging (MRI) has demonstrated edema within the affected compartments after exercise. […] Our findings suggest the cause of CECS is venous outflow obstruction due to functional muscular compression. […] Identifying the etiology of CECS may direct treatment to the problem, rather than the symptoms. […] Based on the observation that venous obstruction is present in most patients with CECS, we believe that at the earliest stages of calf pain, the primary mechanism is functional venous outflow obstruction beyond the patient’s normal capacity to accommodate. […] The significant resolution of pain after relief of venous occlusion provides further evidence that CECS is caused by functional venous outflow obstruction.

  • #21 Compartment Syndrome: Causes, Symptoms, and Treatment
    https://patient.info/bones-joints-muscles/compartment-syndrome-leaflet
    Chronic compartment syndrome (sometimes called 'chronic exertional compartment syndrome’) usually comes on with exercise and gets better at rest. This isn’t a medical emergency, although the symptoms can restrict people from exercising. It’s called 'chronic’ because, although the symptoms come and go, people usually experience them over weeks, months, or longer. […] Chronic compartment syndrome is caused by muscles swelling during exercise. It’s most common in younger athletes, especially runners. […] Long-standing (chronic) compartment syndrome in the lower leg usually affects the anterior fascial compartment. It is caused by a swelling of one of the muscles of the lower leg, called the tibialis anterior muscle. The muscle can swell during exercise. […] Pain from chronic compartment syndrome develops after exercising for a certain amount of time. The limb can also feel tight or tingly. Symptoms get better with resting.

    Chronic exertional compartment syndrome (CECS) is an exercise-induced condition that commonly affects the muscles and nerves of endurance athletes. […] The syndrome causes a set of symptoms that occur after a predictable amount of exercise, for example, the onset of pain and burning occurring 15 minutes into a run. […] Compartment syndrome occurs when the local metabolism cannot clear these byproducts fast enough. As waste products and fluid builds up, so does pressure, and the fascia cannot expand enough to accommodate this change. […] This increased pressure causes decreased blood flow to the muscles and nerves of the compartment, which results in the symptoms of CECS. […] The most commonly affected compartment in CECS is the anterior (front) of the shin. […] In order to diagnose CECS, your doctor might suggest investigations that rule out other causes of pain in this region, such as tendonitis and stress fractures.
  • #23 Forearm Pump: Chronic Exertional Compartment Syndrome of the Forearm – Ortho Rhode Island
    https://www.orthopedicsri.com/blog-items/forearm-pump-chronic-exertional-compartment-syndrome-forearm/
    Forearm pump, or chronic exertional compartment syndrome (CECS) is a condition that causes forearm pain often accompanied by numbness and tingling in the hand. It occurs most commonly in prolonged motocross riding. It may also occur with weight lifting, rock climbing, and paddle sports. Symptoms usually occur during the activity and resolve with rest after the activity is stopped. […] There are distinct compartments within the forearm containing muscles, arteries, and nerves. When prolonged activity causes excessive muscle swelling within a compartment, the pressure may diminish blood flow to the muscles resulting in decreased oxygenation causing pain. Increased pressure and the resulting diminished oxygenation can also affect the nerves in the compartment causing numbness. […] The diagnosis of this uncommon condition is usually by patient history of symptoms occurring with exertion during specific physical activity. They may include excessive forearm swelling, pain, and numbness. The symptoms are noted to resolve after the aggravating activity is completed and time has passed to rest. A diagnostic procedure can also be performed where a needle attached to a pressure gauge is inserted into a forearm compartment before and immediately after activity that causes symptoms. An increase of pressure over a certain level may confirm the diagnosis.

    Chronic, also called exertional, compartment syndrome is typically not an emergency, as in acute compartment syndrome. The pressure within the compartment usually develops over a period of days or weeks, often due to overexertion during rigorous exercise. Chronic compartment syndrome most commonly affects the lower leg, thigh, or buttock and presents within approximately 30 minutes after beginning strenuous activity. […] Other possible factors thought to be involved in developing chronic compartment syndrome include: Enlarged muscles, overly inflexible or thick fascia around the compartment, venous hypertension (pressure in the veins). […] If you are experiencing symptoms of chronic compartment syndrome, you should discontinue the activity causing the pain. Continuing to exercise through the pain can cause permanent damage to the tissue within the compartment.

    Chronic (Exertional) Compartment Syndrome […] The pain and swelling of chronic compartment syndrome is caused by exercise. Athletes who participate in activities with repetitive motions, such as running, biking, or swimming, are more likely to develop chronic compartment syndrome. This is usually relieved by discontinuing the exercise, and is usually not dangerous. […] Chronic compartment syndrome causes pain or cramping during exercise. This pain subsides when activity stops. It most often occurs in the leg. […] To confirm chronic compartment syndrome, your doctor will measure the pressures in your compartment before and after exercise. If pressures remain high after exercise, you have chronic compartment syndrome. […] Nonsurgical treatment. Physical therapy, orthotics (inserts for shoes), and anti-inflammatory medicines are sometimes suggested. They have had questionable results for relieving symptoms. […] Surgical treatment. If conservative measures fail, surgery may be an option. Similar to the surgery for acute compartment syndrome, the operation is designed to open the fascia so that there is more room for the muscles to swell.

    Exertional compartment syndrome causes severe muscle pain and cramping in the legs, making it difficult for athletes and those interested in high-intensity activities to participate due to pressure in the muscle compartment. […] While modifying or avoiding certain physical activities may help with exertional compartment syndrome for some patients, others may require surgery to correct the underlying issue so they can get back to the activities they enjoy. […] Dr. Williams can evaluate the condition to confirm that it is exertional compartment syndrome and not another condition such as shin splints that is causing the pain. […] Some options used to treat exertional compartment syndrome include: […] Fasciotomy. This surgical procedure is the most effective treatment of chronic exertional compartment syndrome. It involves cutting open the inflexible tissue encasing each of the affected muscle compartments to relieve pressure. […] Nerve release surgery. This type of surgery is done to free nerves that are compressed by the affected muscles. It may be done in addition to a fasciotomy or on its own.

    A period of rest may be attempted, as well as avoiding any activities that cause the symptoms. […] However, if the diagnosis of exercise-induced compartment syndrome is clear and the symptoms persist, surgery may be needed. […] The surgery involves releasing (cutting) the tight fascia, called a fasciotomy. […] Exercise-induced compartment syndrome can be a frustrating problem. […] There are two ways to prevent exertional compartment syndrome: avoid or alter exercises that trigger pain and receive surgery.

    Exercise-induced compartment syndrome is a muscle and nerve condition that causes pain, swelling and even disability in the muscles of your arms or legs. […] If left untreated, the pain and disability associated with this syndrome, also known as chronic exertional compartment syndrome, can stop you from doing the activities you love. […] Surgery is the primary treatment for chronic exercise-induced compartment syndrome. Surgery relieves the pressure in the compartment by cutting or removing the connective tissue that prevents it from expanding in response to exercise.
