Uszkodzenie stożka rotatorów
Epidemiologia
Uszkodzenie stożka rotatorów jest najczęstszą przyczyną bólu i dysfunkcji stawu barkowego, dotykającą 20-40% populacji, z wyraźnym wzrostem częstości wraz z wiekiem (np. 28-30% w wieku 60 lat, 51-62% powyżej 80 lat). Roczna zapadalność na schorzenia barku wynosi około 10/1000 osób, z najwyższą w grupie 42-46 lat (25/1000). Epidemiologia wskazuje na istotne czynniki ryzyka, takie jak wiek, palenie tytoniu, hipercholesterolemia, cukrzyca, predyspozycje genetyczne (polimorfizm rs71404070 w genie kadheryny 8, OR 1,25), dominująca kończyna oraz czynniki zewnętrzne, w tym powtarzalne ruchy nad głową i urazy barku. Uszkodzenia obejmują tendinopatię, częściowe naderwania (28-37%) i całkowite przerwania (18-30%), z dominacją ścięgna mięśnia nadgrzebieniowego. Wiek koreluje z wielkością uszkodzenia (średni wiek od 59 do 66 lat w zależności od rozmiaru). Znacząca jest także wysoka częstość bezobjawowych uszkodzeń (MRI wykazuje 34% u osób asymptomatycznych), co komplikuje diagnostykę i monitorowanie.

Epidemiologia uszkodzenia stożka rotatorów
Uszkodzenie stożka rotatorów stanowi najczęstszą przyczynę bólu i dysfunkcji stawu barkowego, a także najczęstsze uszkodzenie ścięgna diagnozowane i leczone u dorosłych12. Szacuje się, że schorzenie to dotyka od 20% do 40% populacji ogólnej3. Częstość występowania uszkodzeń stożka rotatorów wykazuje silną korelację z wiekiem pacjentów.
Częstotliwość występowania w różnych grupach wiekowych
Częstość występowania uszkodzeń stożka rotatorów wzrasta znacząco wraz z wiekiem45:
- W wieku poniżej 20 lat – około 9,7% populacji6
- W wieku 40 lat – około 10%7
- W wieku 50 lat – około 10-20%8
- W wieku 60 lat – około 28-30%910
- W wieku 70 lat – około 31-65%1112
- W wieku 80 lat i więcej – około 51-62%1314
Niemieckie prospektywne badanie przeprowadzone na 411 bezobjawowych barkach wykazało 23% ogólną częstość występowania uszkodzeń stożka rotatorów, przy czym odsetek ten wzrastał do 31% u osób w wieku 70 lat i do 51% u osób w wieku 80 lat17.
Zapadalność i rozpowszechnienie
Roczna zapadalność na schorzenia barku szacowana jest na około 10 przypadków na 1000 osób, z najwyższą zapadalności wynoszącą 25 przypadków na 1000 osób w wieku 42-46 lat18. Dolegliwości barkowe stanowią trzecią najczęstszą przyczynę zaburzeń mięśniowo-szkieletowych, po bólach dolnego odcinka kręgosłupa i bólach szyi19.
W Stanach Zjednoczonych około 3 miliony osób ma rozpoznane uszkodzenie stożka rotatorów20. Każdego roku wykonuje się między 400 000 a 500 000 zabiegów naprawczych stożka rotatorów, a liczba ta ma wzrosnąć w najbliższych latach21.
Struktura demograficzna pacjentów
Badania dotyczące zróżnicowania płciowego w przypadku uszkodzeń stożka rotatorów dostarczają niejednoznacznych wyników. W niektórych badaniach odnotowano przewagę mężczyzn (66%) wśród pacjentów zgłaszających się z powodu chorób stożka rotatorów, podczas gdy inne badania wykazały stosunek mężczyzn do kobiet wynoszący 1:122. W badaniach prowadzonych w populacjach azjatyckich wykazano wyższą częstość występowania u mężczyzn niż u kobiet23.
Nie stwierdzono istotnych różnic rasowych w występowaniu chorób stożka rotatorów24.
Czynniki ryzyka uszkodzenia stożka rotatorów
Czynniki wewnętrzne
Do głównych czynników ryzyka uszkodzenia stożka rotatorów należą252627:
- Wiek – najsilniejszy czynnik predykcyjny, wykazujący wyraźną zależność dawka-efekt (im starszy pacjent, tym większe ryzyko uszkodzenia)28
- Palenie tytoniu – wykazano silny związek między historią palenia a rozwojem uszkodzeń stożka rotatorów29
- Hipercholesterolemia – podwyższony poziom cholesterolu zwiększa ryzyko uszkodzenia30
- Cukrzyca – zwiększa ryzyko uszkodzenia poprzez wpływ na procesy degeneracyjne ścięgien31
- Predyspozycje genetyczne – badania wykazały, że krewni pierwszego stopnia mają podwyższone ryzyko uszkodzenia stożka rotatorów3233
- Dominująca kończyna górna – uszkodzenia częściej występują po stronie dominującej3435
Badania genomowego skanowania asocjacyjnego (GWAS) zidentyfikowały polimorfizm pojedynczego nukleotydu rs71404070, który wykazuje istotną statystycznie korelację z uszkodzeniem stożka rotatorów (p = 2,31×10-8, iloraz szans 1,25 na allel). SNP ten znajduje się w pobliżu genu kadheryny 8, kodującego białko zaangażowane w adhezję komórkową36.
Czynniki zewnętrzne i zawodowe
Czynniki zewnętrzne zwiększające ryzyko uszkodzenia stożka rotatorów obejmują3738:
- Powtarzalne ruchy ponad głową – szczególnie w przypadku zawodów takich jak malarz, stolarz czy pracownik budowlany
- Uprawianie sportów wymagających ruchów nad głową – tenis, pływanie, baseball (zwłaszcza rzucanie)
- Sporty kontaktowe – zwiększające ryzyko urazów
- Historia urazów barku – w tym zwichnięcia stawu ramiennego
Prospektywne badanie przeprowadzone wśród pracowników produkcyjnych i ochrony zdrowia wykazało zwiększone ryzyko rozwoju zespołu stożka rotatorów (RCS) związane z wysiłkiem dłoni na minutę dla trzech tercyli pozycji ramienia: zgięcie ≥45° (≥28,2% czasu, HR = 1,11, CI [1,01, 1,22]), odwiedzenie ≥30° (11,9-21,2% czasu, HR = 1,18, CI [1,04, 1,34]) i odwiedzenie ≥60° (≥4,8% czasu, HR = 1,16, CI [1,04, 1,29])39.
Typy uszkodzeń stożka rotatorów w aspekcie epidemiologicznym
Częstotliwość występowania różnych typów uszkodzeń
Uszkodzenia stożka rotatorów obejmują szerokie spektrum patologii, od tendinopatii, przez częściowe naderwania, do całkowitych przerwań40. W badaniach sekcyjnych zaobserwowano następującą częstość występowania41:
- Częściowe naderwania – 28-37%
- Całkowite przerwania – 18-30%
W badaniach klinicznych częściowe naderwania od strony stawowej są 2-3 razy częstsze niż naderwania od strony podbarkowej. W populacji młodych sportowców naderwania od strony stawowej stanowiły aż 91% wszystkich częściowych naderwań42.
Masywne uszkodzenia stożka rotatorów stanowią do 40% wszystkich uszkodzeń stożka rotatorów43.
Lokalizacja i charakter uszkodzeń
Najczęściej uszkadzanym ścięgnem stożka rotatorów jest ścięgno mięśnia nadgrzebieniowego (supraspinatus)4445. W przypadku urazowych uszkodzeń stożka rotatorów często obserwuje się również uszkodzenie ścięgna mięśnia podłopatkowego (subscapularis)46.
Wielkość uszkodzeń wykazuje korelację z wiekiem pacjentów47:
- Małe uszkodzenia – średni wiek 59 lat
- Średnie uszkodzenia – średni wiek 62 lata
- Duże uszkodzenia – średni wiek 64 lata
- Masywne uszkodzenia – średni wiek 66 lat
Uszkodzenia objawowe i bezobjawowe
Ważnym aspektem epidemiologii uszkodzeń stożka rotatorów jest częste występowanie uszkodzeń bezobjawowych. W badaniach obrazowych (MRI) uszkodzenia stożka rotatorów wykryto u 34% osób asymptomatycznych w różnym wieku48.
W jednym z badań populacyjnych stwierdzono, że49:
- 36% osób z aktualnymi objawami miało uszkodzenia stożka rotatorów
- 16,9% osób bez objawów również miało uszkodzenia stożka rotatorów
W badaniu kohortowym Chingford wykazano, że 48,4% całkowitych przerwań stożka rotatorów było bezobjawowych. Jednakże osoby z co najmniej jednym całkowitym przerwaniem były 1,97 razy bardziej narażone na wystąpienie objawów niż osoby z prawidłowymi ścięgnami obustronnymi (OR 3,53, 95% CI 2,00 do 5,61, p<0,001)50.
Obciążenie systemów opieki zdrowotnej
Uszkodzenia stożka rotatorów i związane z nimi objawy stanowią znaczące obciążenie dla systemów opieki zdrowotnej51:
- 28,8% osób zgłasza się do lekarza pierwszego kontaktu z powodu bólu barku
- 8,9% populacji ogólnej skonsultowało się z lekarzem z powodu bólu barku i całkowitego przerwania stożka rotatorów
- 18,8% populacji ogólnej skonsultowało się z powodu bólu barku i jakiejkolwiek nieprawidłowości ścięgna
- 29,3% populacji ogólnej skonsultowało się z powodu bólu barku
Zapadalność na dolegliwości barkowe wynosi około 11,2 przypadków na 1000 pacjentów rocznie, przy czym ból barku występuje częściej u starszych dorosłych. W populacjach pracujących częstość występowania objawów związanych z barkiem może wynosić nawet 14-18%52.
Uszkodzenia urazowe vs. zwyrodnieniowe
Przy omawianiu epidemiologii uszkodzeń stożka rotatorów ważne jest rozróżnienie między patologią urazową a zwyrodnieniową53.
Urazowe uszkodzenia stożka rotatorów występują częściej u stosunkowo młodych pacjentów (średni wiek 54,7 lat), głównie płci męskiej, którzy doznali upadku lub urazu ramienia w pozycji odwiedzenia i rotacji zewnętrznej54. Wbrew powszechnym przekonaniom, zwykły upadek na bark może spowodować ostre uszkodzenie stożka rotatorów, a uszkodzenia związane z upadkiem nie ograniczają się do młodych osób – mogą dotyczyć pacjentów w każdym wieku55.
Zwyrodnieniowe uszkodzenia stożka rotatorów reprezentują spektrum choroby, od tendinopatii stożka rotatorów związanej ze starzeniem się, do częściowych i całkowitych przerwań stożka56. Silny związek z wiekiem oraz częste występowanie obustronnej choroby wskazują na zmiany fizjologiczne w integralności ścięgna wtórne do wewnętrznej degeneracji, prawdopodobnie związanej ze zmniejszonym zaopatrzeniem odżywczym ścięgna57.
Nadzór i monitorowanie uszkodzeń stożka rotatorów
Monitorowanie uszkodzeń stożka rotatorów stanowi istotne wyzwanie ze względu na wysoką częstość występowania bezobjawowych uszkodzeń oraz różnorodność obrazu klinicznego58. Trudno jest określić dokładną częstość występowania uszkodzeń stożka rotatorów, ponieważ wielu pacjentów jest bezobjawowych i nie ma żadnego bólu ani osłabienia, które skłoniłyby ich do szukania pomocy medycznej59.
Badania przesiewowe populacji z wykorzystaniem technik ultrasonografii barku pozwoliły określić częstość występowania uszkodzeń stożka rotatorów, w tym badanie przekrojowe kobiet w Wielkiej Brytanii, które wykazało, że 22,2% z badanej populacji 1000 osób miało całkowite przerwanie stożka rotatorów60.
Obawy związane z uszkodzeniami stożka rotatorów dotyczą ryzyka progresji, która może prowadzić do zaniku stożka rotatorów i nieodwracalności uszkodzenia, które wcześniej mogło być naprawione. Trudno jednak przewidzieć, które uszkodzenia będą postępować. Całkowite przerwania i zmiany u starszych pacjentów są bardziej narażone na powiększenie61.
W przypadku podejrzenia uszkodzenia, szczególnie ważne jest skierowanie młodych, aktywnych, zdrowych pacjentów z całkowitym przerwaniem stożka rotatorów do ortopedy jak najszybciej, ponieważ wczesne leczenie operacyjne może skutkować lepszymi wynikami62.

- #7 Rotator cuff tear – Wikipediahttps://en.wikipedia.org/wiki/Rotator_cuff_tear
Rotator cuff tears are among the most common conditions affecting the shoulder. […] A rotator cuff tear can be caused by the weakening of the rotator cuff tendons. This weakening can be caused by age or how often the rotator cuff is used. Adults over the age of 60 are more susceptible to a rotator cuff tear, with the overall frequency of tears increasing with age. […] By the age of 50 10% of people with normal shoulders have a rotator cuff tear. […] In an autopsy study of rotator cuff tears, the incidence of partial tears was 28%, and of complete rupture 30%. Frequently, tears occurred on both sides and occurred more often with females and with increasing age. […] Other cadaver studies have noted intratendinous tears to be more frequent (7.2%) than bursal-sided (2.4%) or articular-sided tears (3.6%).

With respect to predisposing factors, advancing age is considered one of the most influential risks. RCTs are primarily symptomatic in persons aged 40 and older. The average incidence of RCT reaches 20-30% in patients aged over 40 years; however, it can reach as high as 62% in patients over 80 years of age. A strong dose association has also been established between smoking history and the development of RC tears. There is also a correlation between RCTs and certain systemic conditions such as rheumatoid arthritis and diabetes. […] In addition to degeneration, acute traumatic tears are associated with repetitive overhead motion and previous shoulder dislocation. Though RCTs are most common in the dominant limb, there is also a higher prevalence in the contralateral shoulder of a previously injured rotator cuff.

Rotator cuff injuries are common. Most of them are wear-and-tear injuries from doing the same arm movements over and over – especially reaching over your head. […] By age 80, most adults have tears. […] Playing sports with repeated shoulder movements increases the risk of a rotator cuff injury, for example, tennis, swimming, and baseball – especially pitching. […] Carpenters, construction workers, and painters are examples of workers who may be more likely to have rotator cuff problems. […] If certain activities bother your shoulder, it’s best to stop doing them and check with your provider.

No known racial variation associated with rotator cuff disease is cited in the literature. In one study, a predominance of male patients (66%) seeking consultation for rotator disease was reported, but in other studies, the male-to-female ratio was 1:1. Rotator cuff disease is more common after age 40 years. The average age of onset has been estimated at 55 years.
- #23 Rotator Cuff Injury: Practice Essentials, Epidemiology, Functional Anatomyhttps://emedicine.medscape.com/article/92814-overview
Rotator cuff injuries are a common cause of shoulder pain in people of all age groups. They represent a spectrum of disease, ranging from acute reversible tendinitis to massive tears involving the supraspinatus, infraspinatus, and subscapularis. Diagnosis is usually made through detailed history, physical examination, and often, imaging studies. […] It is difficult to determine the exact prevalence of rotator cuff tears, as many patients are asymptomatic and do not have any pain or weakness that would lead them to seek medical care. Certain population screening studies have identified the prevalence of rotator cuff tear using shoulder ultrasonography techniques, including a cross-sectional study of women in the UK that showed 22.2% of a study population of 1000 in the UK had a full-thickness rotator cuff tear. Observational studies in Asian populations demonstrated higher prevalence in individuals aged 57 years and in men compared with women.

Rotator cuff tears are common, especially in the fifth and sixth decades of life, but can also occur in the competitive athlete. Genetic differences may contribute to overall injury risk. Identifying genetic loci associated with rotator cuff injury could shed light on the etiology of this injury. We performed a genome-wide association screen using publically available data from the Research Program in Genes, Environment and Health including 8,357 cases of rotator cuff injury and 94,622 controls. We found rs71404070 to show a genome-wide significant association with rotator cuff injury with p = 2.31×10-8 and an odds ratio of 1.25 per allele. This SNP is located next to cadherin8, which encodes a protein involved in cell adhesion. […] The prevalence of rotator cuff tears in the general population is approximately 20%; increasing from 10% in the sixth decade of life to 50% in the ninth decade of life. While the aetiology of rotator cuff tears is poorly understood, the literature supports an age-related progression, primarily affecting middle-aged and older patients. In addition to aging, other risk factors for degenerative tears include smoking, hypercholesterolemia, genetic predisposition and shoulder use.

First, siblings and other close relatives have an elevated risk of rotator cuff tears and show a faster rate of progression of tear size compared to non-related controls. Second, genetic association studies have previously identified 18 single nucleotide polymorphisms (SNPs) associated with rotator cuff tears. […] A better understanding of the genetic loci involved in rotator cuff injury could shed light on the poorly understood molecular basis of tendon injury and repair. Although an individuals genotype is fixed, knowledge of this risk could prompt dedicated preventative measures to potentially decrease the risk of injury.

- #38 Rotator Cuff Injuries | MedlinePlushttps://medlineplus.gov/rotatorcuffinjuries.html
Rotator cuff injuries are common. Most of them are wear-and-tear injuries from doing the same arm movements over and over – especially reaching over your head. […] By age 80, most adults have tears. […] Playing sports with repeated shoulder movements increases the risk of a rotator cuff injury, for example, tennis, swimming, and baseball – especially pitching. […] Carpenters, construction workers, and painters are examples of workers who may be more likely to have rotator cuff problems. […] If certain activities bother your shoulder, it’s best to stop doing them and check with your provider. That’s because early treatment can prevent mild rotator cuff injuries from becoming more serious later on.

Objective This prospective study assessed the risk of developing rotator cuff syndrome (RCS) with separate or specific combinations of biomechanical exposures measures, controlling for individual confounders. […] Compared to other musculoskeletal disorders, rates of work-related shoulder musculoskeletal disorders have been declining more slowly. […] We observed 39 incident RCS cases in 694 person-years (incidence rate = 5.62 per 100 person-years). […] Adjusting for confounders, we found increased risk of incident RCS associated with forceful hand exertions per minute for three upper arm posture tertiles: flexion 45 ( 28.2%-time, HR = 1.11, CI [1.01, 1.22]), abduction 30 (11.921.2%-time, HR = 1.18, CI [1.04, 1.34]), and abduction 60 ( 4.8%-time, HR = 1.16, CI [1.04, 1.29]). […] This study highlights the importance of assessing combinations of exposure to forceful repetition and upper arm elevation when developing interventions for preventing RCS. […] Based on these results, interventions that reduce exposure to forceful repetition (i.e., lower force levels and/or slower exertion rates) may reduce the risk of RCS, especially when upper arm elevation cannot be avoided.

Rotator cuff tears are among the most common conditions affecting the shoulder. […] A rotator cuff tear can be caused by the weakening of the rotator cuff tendons. This weakening can be caused by age or how often the rotator cuff is used. Adults over the age of 60 are more susceptible to a rotator cuff tear, with the overall frequency of tears increasing with age. […] By the age of 50 10% of people with normal shoulders have a rotator cuff tear. […] In an autopsy study of rotator cuff tears, the incidence of partial tears was 28%, and of complete rupture 30%. Frequently, tears occurred on both sides and occurred more often with females and with increasing age.

[…] In a systematic review, Teunis et al. identified 30 separate studies assessing 6112 shoulders for rotator cuff disease in association with patient age. […] This association was maintained independent of shoulder symptoms or history of shoulder dislocation. […] The strong association of age-related rotator cuff degeneration combined with the frequent presence of bilateral disease points to a physiologic change in tendon integrity secondary to intrinsic degeneration, likely related to decreased nutritional supply of the tendon. […] Patient sex has previously been investigated as a risk factor for rotator cuff disease, with conflicting findings. […] With evidence emerging of the age-related changes in the rotator cuff, it has been postulated that development of rotator cuff disease is an inheritable condition. […] Variables that may hasten the intrinsic degenerative changes associated with rotator cuff tears include modifiable risk factors such as diabetes mellitus, dyslipidemia, smoking, and obesity. […] The evidence reviewed here provides a snapshot of the current understanding of the epidemiology of degenerative rotator cuff disease. […] Rotator cuff disease is highly prevalent and often asymptomatic. […] The etiology is multifactorial, with some conflicting evidence. […] Yet again, the strongest predictor of degenerative rotator cuff tears is chronologic age, with obvious genetic and external contributions.

Rotator cuff injuries are a common cause of shoulder pain in people of all age groups. They represent a spectrum of disease, ranging from acute reversible tendinitis to massive tears involving the supraspinatus, infraspinatus, and subscapularis. Diagnosis is usually made through detailed history, physical examination, and often, imaging studies. […] It is difficult to determine the exact prevalence of rotator cuff tears, as many patients are asymptomatic and do not have any pain or weakness that would lead them to seek medical care. Certain population screening studies have identified the prevalence of rotator cuff tear using shoulder ultrasonography techniques, including a cross-sectional study of women in the UK that showed 22.2% of a study population of 1000 in the UK had a full-thickness rotator cuff tear. Observational studies in Asian populations demonstrated higher prevalence in individuals aged 57 years and in men compared with women.

A concern with rotator cuff tears is the risk of progression, which can lead to atrophy of the rotator cuff and a tear that could have been repaired becoming irreversible. However, it is difficult to detect which tears will progress. Full-thickness tears and lesions in older patients are more likely to enlarge. […] The effectiveness and safety of surgery for chronic rotator cuff disease in older patients are unclear. Patients with a suspected tear should be referred to an orthopedist for a discussion about the benefits of conservative vs. operative management. It is especially important to refer young, active, healthy patients with full-thickness tears to an orthopedist as soon as possible because early operative treatment may result in better outcomes.
