Acetabularization as a Protective Factor in Rotator Cuff Arthropathy.

Objective To check if shoulders with acetabularization have better functional results in cases of rotator cuff arthropathy. Methods A clinical and radiological cross-sectional evaluation of 65 shoulders with rotator cuff arthropathy by measuring the range of motion (RoM) of the shoulder, the Constant-Murley score, and the radiological classifications of Hamada and Seebauer. The clinical findings were compared with the radiographic findings. Results According to the classification of Seebauer, we observed better results regarding the RoM in type-A shoulders. There was a statistically significant difference regarding anterior elevation and medial rotation between types A and B ( p < 0.05). Lateral rotation did not show a statistically significant difference between types A and B. The Constant-Murley score presented better results in type A, and there was a statistically significant difference between groups A and B ( p < 0.05). According to the classification of Hamada, we observed that the RoM had better results in types 3, 2 and 1, and there was a statistically significant difference regarding anterior elevation and medial rotation ( p < 0.05) compared with groups 4A, 4B and 5. There was no statistically significant difference between the Hamada groups regarding lateral rotation. According to Hamada, the Constant-Murley score showed better results in types 3, 1 and 2, and there was a statistically significant difference between groups 3 and 5. Conclusion The RoM and shoulder function were better in patients with acetabularization (Seebauer 1A and Hamada 3), and worse in those with glenohumeral arthrosis (Seebauer 1B, 2B and Hamada 4A, 4B and 5).

Resumo Objetivo Verificar se os ombros com acetabularização têm melhores resultados funcionais nos casos de artropatia do manguito rotador. Métodos Avaliação transversal clínica e radiológica de 65 ombros com artropatia do manguito rotador por meio da mensuração da amplitude de movimento (ADM) do ombro, do escore de Constant-Murley, e das classificações radiológicas de Hamada e Seebauer. Os achados clínicos foram comparados com os radiográficos. Resultados Segundo a classificação de Seebauer, com relação à ADM, observamos melhores resultados nos tipos A. Houve diferença estatística significativa na elevação anterior, e rotação medial entre os tipos A e B (p< 0.05). A rotação lateral não demonstrou diferença estatística significativa entre os tipos A e B. O escore de Constant-Murley apresentou melhores resultados nos tipos A, e houve diferença estatística significativa entre os grupos A e B (p< 0,05). Segundo a classificação de Hamada, observamos que a ADM teve melhores resultados nos tipos 3, 2 e 1, e houve diferença estatística significativa para a elevação anterior e a rotação medial (p< 0,05) quando comparadas com os grupos 4A, 4B e 5. Não houve diferença estatística significativa entre os grupos de Hamada em relação à rotação lateral. Ainda segundo Hamada, o escore de Constant-Murley apresentou melhores resultados nos tipos 3, 1 e 2, e houve diferença estatística significativa entre os grupos 3 e 5. Conclusão A ADM e a função do ombro apresentavam-se melhores nos pacientes com acetabularização (Seebauer 1A e Hamada 3), e piores naqueles com artrose glenoumeral (Seebauer 1B, 2B e Hamada 4A, 4B e 5).

Tendon of the long head of the biceps originating from the rotator cuff - An uncommon anatomical variation: case report.

Anatomical variations at the origin of the biceps tendon have been described by several authors, but occurrences of an origin in the supraspinatus are rare. It is unclear whether this variation might contribute toward pathological conditions of the shoulder. Our objective here was to describe a case of an anatomical variation in the origin of the tendon of the long head of the biceps. The clinical information, preoperative images and arthroscopic images relating to a patient with an aberrant origin of the long head of the biceps, which was observed during shoulder arthroscopy, were reviewed. In this case study, the origin of the biceps was found in the rotator cuff, without any origin from the supraglenoid tubercle or upper labrum. This variant did not seem to contribute toward the pathological condition of the shoulder, and standard treatment for the concomitant condition was sufficient for treating it.

As variações anatômicas na origem do tendão do bíceps foram descritas por vários autores, mas a ocorrência de sua origem no supraespinhal é rara. Não está claro se essa variação pode contribuir para condições patológicas do ombro. Nosso objetivo é descrever um caso de uma variação anatômica da origem da cabeça longa do tendão do bíceps.Informações clínicas, imagens pré-operatórias e imagens artroscópicas foram revisadas a partir de um paciente que teve uma origem aberrante da cabeça longa do bíceps observada durante a artroscopia do ombro.Neste estudo de caso, a origem do bíceps foi encontrada no manguito rotador, sem origem do tubérculo supraglenoidal ou labrum superior. Essa variante não parece contribuir para a patologia ombro e o tratamento padrão de patologia concomitante foi suficiente.
