Urazy splotu ramiennego
Etiologia i przyczyny
Urazy splotu ramiennego, obejmujące neurapraksję, rupturę, awulsję oraz nerwiaki, wynikają z mechanicznych uszkodzeń nerwów C5-T1, najczęściej w wyniku nadmiernego rozciągnięcia, zgniecenia lub rozerwania. U noworodków urazy te występują z częstością 1-3/1000 żywych urodzeń, głównie w przebiegu dystocji barkowej, masy urodzeniowej >3,6 kg, porodu pośladkowego czy użycia narzędzi porodowych. U młodzieży i dorosłych dominują urazy pourazowe, zwłaszcza wypadki motocyklowe (83% przypadków), urazy sportowe, upadki i urazy penetrujące. Dodatkowe etiologie to nowotwory, radioterapia, zaburzenia autoimmunologiczne (np. zespół Parsonage’a-Turnera), infekcje oraz zespół górnego otworu klatki piersiowej. Ryzyko urazu zwiększają sporty kontaktowe, wiek 15-25 lat u mężczyzn oraz czynniki okołoporodowe.

Etiologia, przyczyny i czynniki powstawania urazów splotu ramiennego
Urazy splotu ramiennego mogą mieć różne przyczyny, od urazów okołoporodowych do poważnych wypadków komunikacyjnych. Splot ramienny to złożona sieć nerwów, która przewodzi sygnały z rdzenia kręgowego do barku, ramienia i dłoni. Urazy tej struktury mogą prowadzić do różnego stopnia dysfunkcji kończyny górnej, od łagodnych do całkowitego porażenia.12
Mechanizm powstania urazu splotu ramiennego
Urazy splotu ramiennego najczęściej wynikają z nadmiernego rozciągnięcia, zgniecenia lub rozerwania nerwów. Mechanizm urazu często zależy od kierunku i siły działających sił:34
- Uszkodzenie górnych pni splotu (C5-C6) – występuje, gdy bark zostaje gwałtownie pociągnięty w dół, a głowa i szyja są jednocześnie odchylane w przeciwnym kierunku56
- Uszkodzenie dolnych pni splotu (C8-T1) – najczęściej powstaje, gdy ramię zostaje gwałtownie uniesione ponad głowę, zwiększając kąt między ramieniem a klatką piersiową78
Urazy splotu ramiennego mogą obejmować różne typy uszkodzeń nerwów:9
- Awulsja (wyrwanie) – najcięższy rodzaj urazu, gdy nerw zostaje wyrwany z rdzenia kręgowego
- Ruptura (rozerwanie) – nerw zostaje rozerwany, ale nie odłączony od rdzenia kręgowego
- Neuroma (nerwiak) – nerw jest rozerwany i zagoił się z bliznowaceniem, które uciska na uszkodzony nerw
- Neurapraksja – nerw zostaje rozciągnięty, ale nie rozerwany; najczęstszy typ urazu splotu ramiennego10
Urazy porodowe splotu ramiennego
Urazy splotu ramiennego u noworodków najczęściej występują podczas porodu. Szacuje się, że dotykają one od 1 do 3 na 1000 żywych urodzeń.1112 Główne czynniki ryzyka i przyczyny obejmują:
- Dystocja barkowa – gdy barki dziecka zostają zaklinowane za kością łonową matki podczas porodu, co jest najczęstszą przyczyną urazów splotu ramiennego u niemowląt1314
- Duża masa urodzeniowa dziecka – szczególnie powyżej 8 funtów (około 3,6 kg)1516
- Poród pośladkowy (miednicowy) – zwiększa ryzyko urazu splotu ramiennego1718
- Przedłużający się poród – długotrwałe parcie może prowadzić do urazów1920
- Użycie narzędzi porodowych – nieprawidłowe zastosowanie kleszczy lub próżnociągu2122
- Cukrzyca ciążowa – zwiększa ryzyko makrosomii płodu2324
- Otyłość matki – może komplikować przebieg porodu2526
- Historia wcześniejszych urazów splotu ramiennego podczas porodu2728
Warto zauważyć, że chociaż cesarskie cięcie zmniejsza ryzyko urazu, nie eliminuje go całkowicie.2930 Ponadto, ponad połowa urazów splotu ramiennego u noworodków nie ma znanych czynników ryzyka.31
Urazy pourazowe splotu ramiennego
Najczęstszą przyczyną urazów splotu ramiennego u młodzieży i dorosłych są różnego rodzaju urazy:3233
- Wypadki komunikacyjne – zwłaszcza wypadki motocyklowe, które są główną przyczyną poważnych urazów splotu ramiennego (stanowią około 83% przypadków)3435
- Urazy sportowe – szczególnie w sportach kontaktowych, takich jak futbol amerykański, hokej, zapasy czy sztuki walki. Te urazy często nazywane są „stingers” lub „burners” i powstają, gdy nerwy splotu ramiennego zostają nadmiernie rozciągnięte podczas zderzeń z innymi zawodnikami3637
- Upadki – zwłaszcza z wysokości, gdy osoba próbuje złapać się czegoś podczas spadania, powodując nagłe rozciągnięcie nerwów3839
- Urazy penetrujące – rany postrzałowe, rany kłute czy cięte w okolicy szyi lub barku4041
- Urazy związane z długotrwałym noszeniem ciężkiego plecaka – tzw. „backpack palsy”, spowodowane przewlekłym uciskiem pasków plecaka na splot ramienny42
- Zwichnięcia barku – mogą powodować uszkodzenie splotu ramiennego w wyniku rozciągnięcia lub ucisku4344
W przypadku pacjentów z mnogimi obrażeniami, urazy splotu ramiennego są rzadkie, ale współistniejące urazy głowy, tułowia, kończyn i głównych naczyń krwionośnych często mają pierwszeństwo w leczeniu i mogą dodatkowo zaciemniać obraz kliniczny.45
Inne przyczyny urazów splotu ramiennego
Poza urazami pourazowymi i okołoporodowymi, istnieją inne przyczyny uszkodzenia splotu ramiennego:4647
- Nowotwory – guzy mogą rosnąć w okolicy splotu ramiennego lub naciekać jego struktury, powodując ucisk i uszkodzenie nerwów4849
- Radioterapia – leczenie nowotworów w obszarze klatki piersiowej może uszkodzić nerwy splotu ramiennego jako skutek uboczny5051
- Komplikacje chirurgiczne – uszkodzenie nerwów podczas operacji w okolicy szyi, barku lub klatki piersiowej, przypadkowe przecięcie nerwów narzędziami chirurgicznymi5253
- Zaburzenia autoimmunologiczne – mogą powodować zapalenie splotu ramiennego (pleksopatie), np. zespół Parsonage’a-Turnera (określany również jako idiopatyczna pleksopatia ramienna lub amiotrofia neuralgiczna)5455
- Infekcje – niektóre infekcje wirusowe mogą być związane z uszkodzeniem splotu ramiennego5657
- Szczepienia – rzadko mogą być związane z uszkodzeniem splotu ramiennego, szczególnie po szczepieniu przeciwko wirusowemu zapaleniu wątroby typu B58
- Zespół górnego otworu klatki piersiowej (thoracic outlet syndrome) – ucisk nerwów splotu ramiennego przez nieprawidłowe struktury anatomiczne, takie jak dodatkowe żebro szyjne5960
Czynniki zwiększające ryzyko urazu splotu ramiennego
Pewne czynniki mogą zwiększać ryzyko wystąpienia urazu splotu ramiennego:6162
- Uprawianie sportów kontaktowych, zwłaszcza futbolu amerykańskiego i zapasów63
- Udział w wypadkach komunikacyjnych z dużą prędkością, szczególnie na motocyklach64
- Wiek 15-25 lat u mężczyzn (najczęstsza grupa wiekowa dla urazów pourazowych)65
- U noworodków: duża masa urodzeniowa, cukrzyca ciążowa, poród pośladkowy, przedłużający się poród6667
Epidemiologia urazów splotu ramiennego
Częstość występowania urazów splotu ramiennego różni się w zależności od populacji i typu urazu:6869
- Urazy okołoporodowe: 1-3 na 1000 żywych urodzeń7071
- Urazy pourazowe: częstość występowania szacuje się na 1,64 przypadku na 100 000 osób rocznie, jednak prawdopodobnie jest to zaniżona liczba ze względu na niedodiagnozowanie łagodniejszych przypadków7273
- W przypadku mnogich obrażeń pourazowych, urazy splotu ramiennego występują u około 1,2% pacjentów74
Liczba urazów splotu ramiennego wydaje się rosnąć na całym świecie. Zwiększony udział w sportach wysokoenergetycznych oraz wyższe wskaźniki przeżywalności wypadków komunikacyjnych z dużą prędkością mogą być czynnikami przyczyniającymi się do rosnącej liczby tych urazów.75
Rokowanie i powikłania urazów splotu ramiennego
Rokowanie w urazach splotu ramiennego zależy od kilku czynników, w tym rodzaju i stopnia uszkodzenia nerwów oraz szybkości podjęcia interwencji leczniczej.7677
Niektóre urazy splotu ramiennego mogą goić się bez leczenia, szczególnie w przypadku neurapraksji (rozciągnięcia nerwu bez przerwania ciągłości). Natomiast w cięższych przypadkach, takich jak awulsja (wyrwanie korzenia) czy ruptura (przerwanie nerwu), często konieczna jest interwencja chirurgiczna.78
Samoistne wyzdrowienie jest rzadkie w przypadku całkowitego przerwania ciągłości aksonu, objawiającego się całkowitym brakiem potencjałów czynnościowych w badaniach elektrodiagnostycznych.79 Obecność zaniku mięśni i osłabienia w badaniu klinicznym oraz utrata aksonów w badaniach przewodzenia nerwowego sugerują ciężki uraz i w konsekwencji gorsze rokowanie.80
Urazy pourazowe splotu ramiennego mogą mieć dramatyczne konsekwencje dla funkcji motorycznych i czuciowych kończyny górnej, prowadząc do niepełnosprawności i przewlekłego bólu u pacjentów, którzy byli wcześniej zdrowi i aktywni.81
Około 20-30% urazów nerwów splotu ramiennego wymaga leczenia chirurgicznego.82 Mechanizm urazu determinuje odpowiedni czas interwencji chirurgicznej. Większość urazów wynikających z przyczyn naczyniowych wymaga pilnej operacji. W przypadku podejrzenia awulsji korzenia nerwu, zaleca się wczesną eksplorację i rekonstrukcję w okresie od 3 do 6 tygodni. Jeśli nie nastąpiła poprawa funkcjonalna lub zmiana w badaniu fizykalnym lub EMG, zalecana jest opóźniona eksploracja 12 tygodni po urazie.83

The brachial plexus is a network of nerves that carries signals from the upper parts of the spinal cord to your shoulder, arm, and hand. […] Brachial plexus injuries (also known as Erb’s palsy and Dejerine-Klumpke palsy) are caused by damage to those nerves, typically from trauma, tumors, inflammation, pressure, athletic injuries, or being stretched too far. […] Although injuries can occur at any time, many brachial plexus injuries happen when a baby’s shoulders become impacted during delivery and the brachial plexus nerves stretch or tear. […] Some brachial plexus injuries may heal without treatment. […] In some cases (such as avulsion and rupture injuries), surgery is needed.
- #2 Brachial Plexus Injury: What It Is, Symptoms, Treatment & Typeshttps://my.clevelandclinic.org/health/diseases/22822-brachial-plexus-injury
A brachial plexus injury involves sudden damage to the network of nerves that branch off from your spinal cord in your neck and extend down into your shoulder, arm and hand. […] Injury to your brachial plexus often happens when your arm is forcibly pulled or stretched or your head and neck are forcibly pulled away from your shoulder. […] The brachial plexus begins at your neck and crosses your upper chest to your armpit. Injury to this network of nerves often happens when your arm is forcibly pulled or stretched or your head and neck are forcibly pulled away from your shoulder. […] Babies can experience brachial plexus injuries while in the uterus or during delivery. This injury is called neonatal brachial plexus palsy (NBPP). […] Brachial plexus injuries can occur as a result of: Forceful trauma, Tumors, Inflammation, Injuries at birth.

Damage to the upper part of your brachial plexus often occurs when your shoulder is forced down while your neck is forced up and away from your shoulder. […] Damage to the lower part of your brachial nerves is more likely to happen when your arm is suddenly forced above your head. […] Infants can experience brachial plexus injuries due to compression inside their birth mothers uterus or during a difficult delivery. This injury is called neonatal brachial plexus palsy (NBPP). Injury may be caused by the following situations: Your infants head and neck pull toward one side as their shoulders pass through the birth canal, Stretching of your infants shoulders during a head-first delivery, Pressure on your babys raised arms during a breech (feet-first) delivery.
- #4 Brachial Plexus Injuries – OrthoInfo – AAOShttps://orthoinfo.aaos.org/en/diseases–conditions/brachial-plexus-injuries/
Brachial plexus injuries vary greatly in severity, depending upon the type of injury and the amount of force placed on the plexus. The same patient can injure several different nerves of the brachial plexus in varying severity. […] Most traumatic brachial plexus injuries occur when the arm is forcefully pulled or stretched. Many events can cause the injury, including falls, motor vehicle collisions, knife and gunshot wounds, and most commonly, motorcycle collisions. […] It is not known exactly how many brachial plexus injuries occur each year, but the number seems to be growing worldwide. Increased participation in high-energy sports and higher rates of survival from high-speed motor vehicle collisions may be factors in the growing number of these injuries. […] Many brachial plexus injuries occur when the arm is pulled downward and the head is pushed to the opposite side.
- #5 Brachial plexus injury | Beacon Health Systemhttps://www.beaconhealthsystem.org/library/diseases-and-conditions/brachial-plexus-injury?content_id=CON-20127291
Brachial plexus injuries in the upper nerves happen when the shoulder is forced down on one side of the body and the head is pushed to the other side in the opposite direction. […] These injuries can happen in many ways, including: […] Many injuries including those from motor vehicle accidents, motorcycle accidents, falls or bullet wounds can damage the brachial plexus. […] Playing contact sports, especially football and wrestling, or being in high-speed motor vehicle accidents increases the risk of brachial plexus injury.
- #6 Brachial Plexus Injuries – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK482305/
Obstetric injury; severe trauma caused by falls, direct, blunt blows, or high-speed motor vehicle collisions; penetrating injury; forceful traction injury; and compression injury can all result in damage to the brachial plexus. […] Upper trunk traction injuries occur when the head and neck are violently pulled caudally from the shoulder and torso. Similarly, lower trunk traction injuries occur when the arm is violently abducted above the head. […] In the polytrauma patient, injuries to the brachial plexus are rare, but concomitant blunt trauma to the head, torso, extremities, and major blood vessels often takes precedence for treatment and further obscures the clinical picture.
- #7 Brachial Plexus Injuries – OrthoInfo – AAOShttps://orthoinfo.aaos.org/en/diseases–conditions/brachial-plexus-injuries/
Lower brachial plexus injuries occur when the arm and shoulder are forced upward, increasing the angle between the arm and the chest. […] Brachial plexus injuries caused by a gunshot wound do not typically damage the nerve severely. […] A brachial plexus injury caused by a penetrating wound, such as a knife wound (laceration), may damage or cut the nerve. This type of injury to the nerve will not typically recover on its own, prompting more immediate treatment. […] Because brachial plexus injuries are typically caused by high-energy, forceful events, many patients have additional injuries.

Erbs palsy is muscle weakness in the arm or shoulder that can occur as a result of an injury sustained during birth or later in life. Its most common in infants who injured their shoulders during delivery. […] The brachial plexus is a group of five nerves that connect the spine to the arm and hand. These nerves allow your shoulder, arms and hands to feel and move. If these brachial plexus nerves dont work well due to stretching or tearing, the condition is called a brachial plexus palsy. […] There are four types of brachial plexus injuries: Avulsion is when the nerve rips away from the spine and is the most serious type of Erb’s palsy. Rupture is when the nerve is torn, but not from the spine. Neuroma is when the nerve has torn and healed but has left scar tissue. The scarred tissue puts pressure on the injured nerve and prevents it from conducting signals to the muscles. Neurapraxia is when the nerve is stretched but not torn. Neurapraxia is the most common type of brachial plexus injury.

The primary risk factor for a brachial plexus birth injury is shoulder dystocia. This medical emergency is a delivery complication that happens when a babyâs shoulder gets stuck behind the motherâs pelvic bone. […] Maternal risk factors for neonatal brachial plexus palsy include having gestational diabetes, maternal obesity, or a history of delivering large babies. […] Yes, many of the causes of brachial plexus injury at birth could have been prevented with proper medical care.
- #14 Brachial Plexus & Traumatic Nerve Injury: Conditions | HSShttps://www.hss.edu/brachialplexuscenter-conditions.asp
In brachial plexus injuries, the term avulsion is used to describe a condition where the roots of the nerves are torn away from the spinal cord. […] Multiple root avulsion is the most common diagnosis in high-energy, traumatic brachial plexus injuries, such as occur in a motorcycle or off-road vehicle accident. […] Injury to the axillary nerve and resulting paralysis of the deltoid muscle usually results from shoulder trauma such as dislocation and/or fracture. […] Motor vehicle accidents, a fall from a height, or a sports injury from skiing, snowboarding, football or rugby are among the common causes. […] The term birth palsy (or paralysis) refers to injuries to the brachial plexus incurred as the baby emerges from the birth canal. […] In such instances, the baby’s shoulder is stuck against the mother’s pubic bone during delivery (a condition also referred to as shoulder dystocia), as the head emerges in the other direction, resulting in a traction injury.
- #15 Newborn Brachial Plexus Injuries (for Parents) | Nemours KidsHealthhttps://kidshealth.org/en/parents/brachial-plexus.html
Brachial plexus injuries affect the nerve network that provides feeling and muscle control in the shoulder, arm, forearm, hand, and fingers. […] In newborns, these injuries can happen if: the birth is complicated by a breech (bottom-first) delivery, the mother has a very long labor, the baby weighs 8 pounds or more, the baby’s shoulders are too wide to fit through the birth canal. […] During childbirth, a brachial plexus injury can happen if the baby’s neck is stretched to one side. […] When a strong force increases the angle between the neck and shoulders, the brachial plexus nerves might stretch or tear. The injury may also pull the nerve roots of the brachial plexus from the spinal cord.

- #35 Brachial Plexus Injury in Adultshttps://www.thenerve.net/journal/view.php?number=90
Brachial plexus injury (BPI) is a severe peripheral nerve injury affecting upper extremities, causing functional damage and physical disability. The most common cause of adult BPI is a traffic accident, such as motorcycle accidents. Most patients are young men between 15 and 25 years of age. Other traumatic causes include sports injuries, incised wounds, gunshot wounds, carrying a heavy backpack, and inappropriate operative positioning. Non-traumatic causes consist of tumors, irradiation, and congenital abnormalities such as cervical ribs. In recent literature, the prevalence rate is about 1.2% after multiple traumatic injuries, and the annual incidence is about 1.64 cases out of 100,000 people. […] Closed trauma is the most common cause of adult traumatic BPI. Most common mechanism of closed trauma causing BPI is compression or traction. BPIs caused by compression may be accompanied by fractures or dislocations of the clavicle or the head and neck of humerus. Gradual compression results from the postoperative edema or fibrosis is also one of the hypotheses to explain BPI occurrence, although there is controversy. In BPIs caused by traction, the nerve may be injured, avulsed from the root, or significantly stretched. Traction-related injuries can be resulted from violent widening of the scapulo-humeral angle accompanied by the shoulder dislocations and fractures of the humerus, which cause pressure on the infraclavicular neurovascular bundle above the humeral head, and injury of the infraclavicular plexus. One of the examples is when someone falls on a laterally hyperabducted and internally rotated arm and the movement of the scapula is blocked by the ground, and infraclavicular plexus is stretched over the humeral head.

Brachial plexus injury (BPI) is a severe peripheral nerve injury affecting upper extremities, causing functional damage and physical disability. The most common cause of adult BPI is a traffic accident, such as motorcycle accidents. Most patients are young men between 15 and 25 years of age. Other traumatic causes include sports injuries, incised wounds, gunshot wounds, carrying a heavy backpack, and inappropriate operative positioning. Non-traumatic causes consist of tumors, irradiation, and congenital abnormalities such as cervical ribs. In recent literature, the prevalence rate is about 1.2% after multiple traumatic injuries, and the annual incidence is about 1.64 cases out of 100,000 people. […] Closed trauma is the most common cause of adult traumatic BPI. Most common mechanism of closed trauma causing BPI is compression or traction. BPIs caused by compression may be accompanied by fractures or dislocations of the clavicle or the head and neck of humerus. Gradual compression results from the postoperative edema or fibrosis is also one of the hypotheses to explain BPI occurrence, although there is controversy. In BPIs caused by traction, the nerve may be injured, avulsed from the root, or significantly stretched. Traction-related injuries can be resulted from violent widening of the scapulo-humeral angle accompanied by the shoulder dislocations and fractures of the humerus, which cause pressure on the infraclavicular neurovascular bundle above the humeral head, and injury of the infraclavicular plexus. One of the examples is when someone falls on a laterally hyperabducted and internally rotated arm and the movement of the scapula is blocked by the ground, and infraclavicular plexus is stretched over the humeral head.

Brachial plexus and peripheral nerve injuries prevent the nerves from carrying signals between the brain and muscles. Over time, the muscles can become weak and lose function. […] These nerves can be damaged when they are stretched, pinched or cut. The most common conditions are: Brachial plexus injuries at birth. If a babyâs shoulders get stuck in the birth canal during a vaginal birth, the brachial plexus nerves can be stretched and injured. This can make it difficult to move the arm or flex the arm muscles. This injury happens in 1.5 of every 1,000 births. […] Brachial plexus trauma injuries. These nerves also can be damaged in a fall from a bicycle or ATV, in a motor vehicle accident or from a sports injury. […] Thoracic outlet syndrome. This condition is more common in adolescents. It occurs when an abnormal growth from a rib or the spinal column puts pressure on the brachial plexus nerves, causing lack or movement and pain in the arm. […] Brachial plexus injuries at birth occur in 1.5 of every 1,000 births. […] Thoracic outlet syndrome is when abnormal ribs or spinal column growths injure brachial plexus.

The mechanism of injury determines the appropriate timing of surgical intervention. Most injuries result from vascular causes require emergency surgery. If there is complete C5 and T1 avulsion injuries, early exploration within 1 to 2 weeks is recommended. When root avulsion is highly suspicious, early exploration and reconstruction between 3 and 6 weeks is indicated. If there has been no functional recovery or no change in the physical examination or EMG, delayed exploration at 12 weeks after injury is recommended.
