Background: Subcoracoid impingement has been implicated as a cause of anterior shoulder pain and subscapularis tendon tears. Purpose/Hypothesis: The purpose of this study was to evaluate the bony anatomy of the coracoid process and the subcoracoid space. We hypothesized that age-related changes that may contribute to subcoracoid impingement occur in the subcoracoid space. Study Design: Descriptive laboratory study. Methods: In total, 418 skeletal shoulder specimens were included in this study. We utilized 214 shoulders from a young cohort (25-35 years of age) and 204 shoulders from an older cohort (>55 years of age) for comparison. We evaluated several morphological characteristics of the coracoid process and the subcoracoid space: coracoid width, coracoid shape, coracoid thickness, and subcoracoid distance. Each coracoid was observed for the presence of spurring or other morphological changes. Results: The mean anteroposterior (AP) thickness of the coracoid tip was 7.9 and 9.4 mm in our young female and male cohorts, respectively, while the mean AP thickness was 8.1 and 9.7 mm in our older female and male cohorts, respectively. The coracoid tip was hooked in 31 of 108 young female shoulders compared with 55 of 102 older female shoulders, and the coracoid tip was hooked in 25 of 106 young male shoulders compared with 45 of 102 older male shoulders. The mean subcoracoid distance in neutral rotation was 14.8 and 12.5 mm in young and older female shoulders, respectively, while the mean subcoracoid distance in internal rotation in these same cohorts was 8.7 and 7.0 mm, respectively. The mean subcoracoid distance in neutral rotation was 14.8 and 13.3 mm in young and older male shoulders, respectively, while the mean subcoracoid distance in internal rotation was 8.6 and 8.1 mm in young and older male shoulders, respectively. Conclusion: The principal findings of our study demonstrate that anatomic changes implicated in subcoracoid impingement may be developmental and worsen with age. The subcoracoid space was narrower in our older cohort of shoulders. Additionally, these older shoulders also had a greater AP width and a more hooked coracoid compared with young shoulders. Clinical Relevance: Narrowing of the subcoracoid space has been shown to be implicated as a cause of anterior shoulder pain and subscapularis tendon tears. This is the first study to show that the morphological changes implicated in subcoracoid impingement become more prevalent with age. This may help to explain the increasing prevalence of subscapularis tendon tears in older patients. Furthermore, subcoracoid decompression may be seen as an option for older patients with anterior shoulder pain and subscapularis tendon tears.

Introdução: As lesões do tendão musculo subescapular (TMSE) do manguito rotador passaram a ter aumento de sua incidência com as avançadas técnicas de diagnostico por imagem e artroscópicas. A Ressonância Nuclear Magnética (RM) apresenta boa sensibilidade e especificidade permitindo adequada acurácia diagnóstico. Objetivo: avaliação da concordância interobservador da RM para Lesões do TMSE comparada à artroscopia. Métodologia: 49 pacientes sintomáticos foram submetidos à RM para diagnóstico de lesão do TMSE e avaliação da Classificação de Lafosse, tendo sua concordância avaliada através da Artroscopia diagnostica. Resultados: A acurácia global foi 68% para concordância diagnóstica da Lesão do TMSE e 57,1% para concordância na classificação de Lafosse. Discussão: obteve-se concordância para o diagnóstico de Lesão ou ausência de Lesão do TMSE de 0,49 e a concordância para a Classificação de Lafosse foi de 0,30. Conclusão: o diagnóstico da lesão do TMSE através da RM é de difícil realização.Descritores: Manguito Rotador; Artroscopia; Imagem por Ressonância Magnética.ReferênciasTicker JB, Warner JJ.
