Objectives: To outline the epidemiological profile of diabetic patients with Charcot arthropathy affecting the midfoot alone or extending from the midfoot to the hindfoot; To assess the results from the treatment that these patients undergo, according to a preestablished protocol, over the medium term. Methods: We retrospectively evaluated 88 patients (110 extremities) with Charcot arthropathy of the midfoot. The minimum follow-up period was 12 months. We included 45 patients with Charcot arthropathy affecting the tarsal-metatarsal joints (51%); 20 patients in whom the talonavicular, calcaneocuboid and subtalar joints were affected (23%); and 23 patients in whom both the midfoot and hindfoot were affected (26%), as described by Brodsky and Trepman. We defined the treatment as successful when a functional foot was preserved; and unsuccessful when the foot was amputated. Results: From treating Charcot arthropathy primarily involving the midfoot were satisfactory in the cases of 75 patients (85%) treated according to our protocol. For the patients with severe lesions affecting both the midfoot and the hindfoot, a greater number of complex operations (i.e. arthrodesis) were needed in order to obtain the same overall rate of satisfactory results. The osteoarticular lesions originating in the midfoot probably extended progressively to the hindfoot because of delayed diagnosis with inadequate early treatment. Conclusion: It was possible to preserve a functional extremity in 85% of the patients. Severe lesions involving the midfoot and extending to the hindfoot required a greater number of surgical procedures to treat them.
ResumoNo contexto do tratamento cirúrgico dos pacientes jovens com lesões irreparáveis da porção posterossuperior do manguito rotador, a técnica mais usada é a transferência do tendão do grande dorsal para a porção superolateral do tubérculo maior, conforme descrita e preconizada por Gerber et al. Entretanto, duas características dessa técnica podem levar a resultados ruins e complicações: (i) a deiscência da origem do deltoide, que ocorre devido à sua violação durante a criação da via em golpe de sabre e (ii) a ruptura pós-operatória da inserção da transferência. Na tentativa de solucionar esses dois problemas, as seguintes modificações foram feitas à técnica cirúrgica original. Por meio de uma única via deltopeitoral, o tendão do grande dorsal é isolado e desinserido do úmero. Ele é então alongado e reforçado com um enxerto tendíneo homólogo, transferido ao redor do úmero e fixado à porção superolateral do tubérculo maior. Não foi usada imobilização pós-operatória com órtese toracobraquial rígida.

Resumo
Objetivo Identificar agentes bacterianos em amostras de cirurgias do ombro de pacientes sem histórico de infecção e de cirurgias prévias no ombro.
Métodos Amostras de tendão, bursa e osso foram coletadas no intraoperatório, armazenadas em frascos estéreis a seco e enviadas para análise de crescimento de cultura em meios para agentes aeróbios e anaeróbios no laboratório credenciado ao hospital. Foram analisados os resultados de 141 amostras de 47 ombros.
Resultados Obtivemos resultados de culturas negativas em 46 casos (97,8%) e em 140 amostras (99,2%). Apenas um paciente apresentou resultado positivo, com crescimento bacteriano do Staphylococcus hominis em uma das três amostras coletadas.
Conclusões Não evidenciamos taxas de crescimento bacteriano condizentes com a literatura internacional, alertando para a baixa eficácia dos métodos laboratoriais utilizados no nosso país.
ObjectiveTo evaluate clinical and radiological results with open reduction and internal fixation of severe fractures of the proximal humerus in the patients over the age of 60 years.MethodsBetween June 1992 and February 2011, 21 patients with FGEPU over the age of 60 years were treated by open reduction and internal fixation at the Group of Shoulder and Elbow Department of Orthopaedics and Traumatology of Santa Casa de São Paulo Medical School. 18 patients were reviewed.ResultsTwo patients had excellent results, 12 good, three regular and one bad. Therefore, we find that 77.7% of these had good and excellent results. All patients were satisfied with the treatment and only three patients did not return to previous activities. Mean postoperative mobilities were 122° elevation (90–150°), 39 lateral rotation (20–60°) and medial rotation of T11 (T5 to sacro iliac joint).ConclusionOpen reduction and internal fixation of FGEPU may also be indicated for elderly patients and obtained 77.7% of good and excellent results. Statistically (p < 0.05), the anatomical reduction of the fracture was found to be important for obtaining good results.
Resumo
Objetivo O objetivo primário do presente trabalho é avaliar os resultados funcionais de uma modificação na transferência do grande dorsal no ombro para o tratamento de lesões póstero-superiores irreparáveis do manguito rotador. O objetivo secundário é avaliar as variáveis que podem influenciar os resultados.
Técnica cirúrgica Por meio de uma única abordagem deltopeitoral, o tendão do músculo grande dorsal é desinserido reforçado e alongado com um enxerto tendíneo homólogo, transferido para o úmero e fixado em posição superolateral ao tubérculo maior e anterior ao músculo subescapular.
Métodos Avaliação funcional retrospectiva de 16 casos. O período médio de acompanhamento foi de 21 meses (12–47 meses). Os resultados pós-operatórios (no último acompanhamento) foram comparados aos pré-operatórios, bem como a outras variáveis pré, intra e pós-operatórias.
Resultados Todos os pacientes ficaram satisfeitos (exceto um). A pontuação média da University of California, Los Angeles (UCLA) aumentou de 11,6 (8–16) para 27,3 (17–30) (p < 0,001). A dor, a função e a força do ombro apresentaram melhora estatisticamente significativa (p < 0,001). A força, porém, não voltou ao valor normal. A amplitude de movimento ativa média apresentou as seguintes melhoras: elevação frontal, de 106° (60–140°) para 145° (130–160°) (p < 0,001); rotação externa, de 30° (0–60°) para 54° (40–70°) (p < 0,001); e rotação interna, de L1 (glúteo a T7) para T10 (T12–T3) (p < 0,05). Nenhuma complicação foi observada. A pseudoparesia pré-operatória foi revertida em todos os seis casos em que foi observada. Nenhuma das variáveis analisadas influenciou os desfechos, nem mesmo a pseudoparesia.
Conclusões A curto prazo essa técnica é segura e eficaz na recuperação da pseudoparesia e na melhora da dor, da função e da força do ombro.
ObjectiveThe aim of this study was to establish an indirect, easy-to-use, predictable and safe means of obtaining the true degree of displacement of fractures of the neck of the fifth metacarpal bone, through oblique radiographic views.MethodsAn anatomical specimen from the fifth human metacarpal was dissected and subjected to ostectomy in the neck region. A 1-mm Kirschner wire was fixed to the base of the fifth metacarpal bone, perpendicular to the longitudinal axis of the bone and parallel to the ground. Another six Kirschner wires of the same diameter were bent over and attached to the ostectomized bone to simulate fracture displacement. Axial rotation of the metacarpus was used to create oblique radiographic views. Radiographic images were generated with different angles and at several degrees of rotation of the bone.ResultsWe deduced a mathematical formula that showed the true displacement of fractures of the neck of the fifth metacarpal bone by means of oblique radiographs.ConclusionsOblique radiographs at 30̊ of supination provided the best view of the bone and least variation from the real value of the displacement of fractures of the fifth metacarpal bone. The mathematical formula deduced was concordant with the experimental model used.
