Objectives To analyze the functional outcomes in patients submitted to videoarthroscopic surgical treatment for compleat rotator cuff tears of the shoulder, with a minimum follow-up of 10 years. Methods A total of 63 patients (63 shoulders) underwent videoarthroscopic surgical repair for compleat rotator cuff tears with a minimum follow-up of 10 years. The postoperative functional outcomes of these patients were evaluated using the Constant and University of California at Los Angeles (UCLA) scores. Results The functional evaluation revealed mean UCLA and Constant scores of 26 and 93 points, respectively. Ninety-one percent of the subjects had satisfactory Constant scores, whereas 62% presented satisfactory UCLA scores. Conclusion The arthroscopic repair of rotator cuff complete tear was effective even in the long term (minimum follow-up period of 10 years). The age of the patients before surgery, size of the lesion, the degree of fatty infiltration, and evaluation of muscle trophism are important predictors of prognosis.

Neurothekeomas, also known as neural sheath myxomas, are rare benign tumors of the neural sheath affecting most commonly the head, arms and shoulder of women in their 2nd and 3rd decades of life. Due to the low prevalence and undefined clinical picture, they are hardly considered in the initial differential diagnosis of skin tumors. We report the case of a 24 year-old woman who was seen in 2016 reporting > 1 year of moderate pain and limited mobility of her left shoulder. Clinical evaluation revealed restricted mobility of the affected shoulder and nuclear magnetic resonance imaging showed a T2-weighted contrast-enhanced multilobular mass in the quadrilateral area apparently invading the adjacent humeral cortical region. Histopathology of a needle sample material revealed loose fibroconnective tissue with no signs of invasion, mitosis or atypical figures. Successful surgical excision was performed and the diagnosis of neurothekeoma was confirmed after detailed histopathology, including immunohistochemistry. The patient was asymptomatic at 18 months of follow-up, with full recovery of shoulder movement and no signs of relapse.

Objective To describe a new presentation of tears and retears of the rotator cuff, which we denominate captured rotator cuff (CRC). We also aim to evaluate it clinically and through images. Methods We assessed retrospectively 16 patients with intraoperative diagnosis of CRC between March 2005 and September 2017; by means of imaging (radiography and magnetic resonance imaging [MRI]) and functional scores (UCLA and Constant & Murley). In images we analyzed the evolution for rotator cuff arthropathy and presence of retears. Functionally, we compared the affected side with the contralateral side and extensive lesions with nonextensive. Results Five (31.25%) patients presented with rotator cuff arthropathy, and 10 (62.5%) with retears. Three (75%) patients with nonextensive lesions had good/excellent UCLA and Constant & Murley scores. In patients with extensive lesions, when the Constant & Murley score was evaluated, 6 (50%) presented good/excellent results, and in the UCLA score, 7 (58.3%). Comparing the affected side (Constant 74.72 points; UCLA 20 points) with the contralateral side (Constant 96.96 points; UCLA 25.63 points), there were worse functional results with statistical significance. Conclusion The diagnosis of CRC is suspected by characteristic findings on MRI and confirmed in arthroscopy. The affected shoulders present worse functional postoperative scores. Resumo Objetivo Descrever uma nova apresentação de ruptura e rerruptura do manguito rotador (MR), a qual denominamos manguito capturado (MC). Objetivamos também avaliá-la clinicamente e por meio de imagens. Métodos Foram avaliados retrospectivamente 16 pacientes com diagnóstico intraoperatório de MC no período de março de 2005 a setembro de 2017; por meio de exames de imagem (radiografia e ressonância magnética [RM]) e escores funcionais (UCLA e Constant & Murley). Nas imagens, analisamos a evolução para artropatia do manguito rotador e presença de rerrupturas. Funcionalmente, comparamos o lado afetado com o contralateral e as lesões extensas com nãoextensas. Resultados Cinco (31,25%) pacientes evoluíram com artropatia do manguito rotador e 10 (62,5%) tiveram rerrupturas. Três (75%) pacientes com lesões não extensas tiveram UCLA e Constant & Murley bons/excelentes. Nos pacientes com lesões extensas, quando avaliado Constant & Murley, 6 (50%) apresentaram resultados bons/excelentes, e no escore UCLA, 7 (58,3%). Comparando o lado acometido (Constant 74,72 pontos; UCLA 20 pontos) com o contralateral (Constant 96,96 pontos; UCLA 25,63 pontos), houve pior resultado funcional com significância estatística. Conclusão O diagnóstico de MC é suspeitado por achados característicos na RM e confirmado na artroscopia. Os ombros acometidos apresentam piores escores funcionais pós-operatórios.

Objective To clinically evaluate the results of patients undergoing arthroscopic surgical treatment of anterior shoulder instability. Methods A retrospective study of 94 patients. With a minimum follow-up of 24 months, we sought to correlate the characteristics of the patients and the surgery, such as age, gender, type of injury (traumatic or atraumatic) and the patient's position during surgery (lateral decubitus and beach chair) with the results obtained, the recurrence rate, the lateral rotation loss, the residual pain, and the functional scores of Carter-Rowe, University of California at Los Angeles (UCLA), and Constant-Murley. Results We observed a recurrent dislocation rate of 11.7%, lateral rotation loss in 37.23% of the patients, and some degree of residual pain in 51.6% of them. We obtained a mean Carter Rowe score of 85.37, representing 86% of good/excellent results. In the UCLA score, we obtained 88% of good/excellent results, similar to those obtained in the Constant-Murley score (86%). Conclusion The arthroscopic treatment of the anterior instability of the shoulder presents satisfactory results and low index of important complications, being the method of choice for most patients. Resumo Objetivo Avaliar clinicamente os resultados de pacientes submetidos a tratamento cirúrgico artroscópico de instabilidade anterior do ombro. Métodos Estudo retrospectivo de 94 pacientes. Com seguimento mínimo de 24 meses, buscamos correlacionar as características dos pacientes e da cirurgia, como idade, gênero, tipo de lesão (traumática ou atraumática) e posição do paciente na cirurgia (decúbito lateral e cadeira de praia) com os resultados obtidos, avaliando o índice de recidivas de luxação, a perda de rotação lateral, a dor residual, e os escores funcionais de Carter-Rowe, da University of California at Los Angeles (UCLA) e de Constant-Murley. Resultados Observamos uma taxa de recidiva de luxação de 11,7%, perda de rotação lateral em 37,23% dos pacientes, e algum grau de dor residual em 51,6%. Obtivemos uma pontuação média no escore de Carter Rowe de 85,37, representando 86% de resultados bons/excelentes. No escore da UCLA, obtivemos 88% de resultados bons/excelentes, índice semelhante aos encontrados no escore de Constant-Murley (86%). Conclusão O tratamento artroscópico da instabilidade anterior do ombro apresenta resultados satisfatórios e baixo índice de complicações importantes, podendo ser o método de escolha para a maioria dos pacientes.

Most shoulder injuries occur due to repetitive overhead movements. Before studying the treatment of these shoulder injuries, it is paramount that health professionals have an understanding of the etiology of and the underlying mechanisms for shoulder pathologies. The act of overhead throwing is an eloquent full-body motion that requires tremendous coordination from the time of force generation to the end of the pitch. The shoulder is a crucial component of the upper-body kinetic chain, as it transmits force created in the lower body to the arm and hand to provide velocity and accuracy to the pitch.

Massive irreparable posterosuperior rotator-cuff tears are debilitating lesions that usually require surgical treatment. Even though there is no consensus regarding the best surgical technique, tendinous transfers around the shoulder are the most commonly performed procedures. The latissimus dorsi tendon remains the most commonly used, but different modifications to the original technique have been shown to minimize complications and to improve functional results and satisfaction. Other techniques, such as the transfer of the lower trapezius tendon, are promising and should be considered, especially for patients with isolated loss of external rotation. The present paper is a literary review regarding tendon transfers for irreparable posterosuperior rotator-cuff tears.

The influence of genetic inheritance has been increasingly investigated in shoulder disorders, such as rotator cuff injury, instability and frozen shoulder. Although the initial findings are enlightening, it is necessary to progressively build a database of genetic markers to catalog genomic profiles that, later, may contribute for predicting the risk of the disease, as well as to the development of better diagnostic and treatment tools. The present article seeks to update what is evidence of genetic studies in the literature for these diseases, from polymorphism analyses, expression of candidate genes in tissues and broad genomic association studies (GWAS). However, it is necessary to point out that there is great difficulty in replicating and using the findings, mainly due to the lack of statistical power, the high rate of false-positive results and the large number of variables involved. Resumo A influência da herança genética tem sido cada vez mais investigada nas afecções do ombro, como a lesão do manguito rotador, instabilidade e ombro congelado. Ainda que os achados iniciais sejam pouco esclarecedores, é necessário construir progressivamente um banco de marcadores genéticos para catalogar perfis genômicos que, mais adiante, poderão contribuir para a previsão do risco da doença, desenvolvimento de melhores ferramentas de diagnóstico e tratamento. O presente artigo busca atualizar o que há de evidências de estudos genéticos na literatura para essas doenças, desde análises de polimorfismos, expressão de genes candidatos em tecidos e estudos de associação genômica ampla (GWAS, na sigla em inglês). Porém, é necessário apontar que existe grande dificuldade na replicação e utilização dos achados, principalmente em razão da falta de poder estatístico, da alta taxa de resultados falso-positivos e da grande quantidade de variáveis envolvidas.
