Resumo Objetivo Avaliar radiograficamente os resultados pós-operatórios dos pacientes com fratura da extremidade proximal do úmero em duas partes do colo cirúrgico tratados com fixação percutânea com fios rosqueados. Métodos Avaliamos radiograficamente os resultados da fixação percutânea com fios rosqueados das fraturas da extremidade proximal do úmero realizadas em nosso serviço. Foram avaliadas as imagens pré- e pós-operatórias de 42 pacientes, avaliando-se radiografias com até 8 semanas de pós-operatório. Consideramos na avaliação o desvio da fratura pré-operatório, a perda da redução e a consolidação da fratura. Resultados O índice de consolidação nos casos avaliados foi de 90,4%, com perda da redução em 16,6% dos casos e não obtida a consolidação em apenas 4 casos. Foi observada uma predominância de determinado padrão de fratura nos casos que perderam a redução. Conclusão O estudo permitiu considerar a técnica de fixação percutânea com fios rosqueados uma alternativa no arsenal terapêutico da fratura da extremidade proximal do úmero do colo cirúrgico, com contraindicação para os traços de fratura baixos na metáfise e com acometimento da cortical medial/lateral.
Objective: To study the influence of patellar resurfacing on quality of life under a standardised score. The chosen score was the Knee Society Score (KSS), which considers range of motion, pain, contractors, alignment and stability. Methods: Retrospective review of 60 patients submitted to total knee arthroplasty (TKA) was divided into two groups: with patellar resurfacing (PR) and without patellar resurfacing (NPR). We reviewed data from these patients containing the KSS, which are routinely used in our service. Data were analysed from 2013 to 2014, with a minimal patient follow-up of 18 months. Results: There were no unsatisfactory scores in our study. Total scores (KSS) were similar between the groups (mean KSS: PR = 88.36 ± 9.64; NPR = 84.26 ± 9.44 [p = 0.1]). While stratifying into groups (poor, fair, good, excellent), we found excellent results in 84.8% of PR versus 59.3% NPR (p = 0.056). These data did not reach statistical significance and can therefore be considered a coincidental result. Conclusion: Although these results did not show statistical significance (p = 0.056), patellar resurfacing patients tend to get more "excellent" results after 18 months of follow-up in quality of life when evaluated by KSS. Perhaps a larger amount of patients would suffice to acquire statistical significance in a future study.
Introduction: Total knee arthroplasty, being a major surgery, carries a risk of post-operative deep vein thrombosis (DVT). The main objective of the present study was to elucidate the association of clinical, laboratory, and echographic findings with the occurrence of DVT. Patients and Methods: The present study was prospective and non-randomized, with restricted exclusion criteria. Forty patients were submitted to total knee arthroplasty due to osteoarthritis. Patients were clinically evaluated by laboratory tests, assessment of pain and calf circumference, and the presence of Homans' sign. Echo Doppler was performed in each patient on postoperative day 7. The echographic evaluation divided the patients into two groups: positive (G1) and negative for thrombosis (G2). All patients received prophylactic heparin during the 7-day hospital admission. Results: Eleven patients complained of pain (analgesic medication was used during the entire admission). Leg circumference variation from the pre-operative period to post-operative day 7 was: G1, 1.70 ± 1.12 cm and G2, 0.68 ± 1.25 cm (p = 0.03). Homans' sign was considered positive in 10 patients. Echographic evaluation was positive in 11 patients (27.5%). No cases of pulmonary embolism, infection, or death were observed. Conclusions: The incidence of DVT was 27.5%, with an increase in leg circumference being the main predictive factor (p = 0.03).
ResumoAs lesões do manguito rotador do ombro podem ter diversas configurações, e são divididas e/ou classificadas conforme o tamanho da lesão, o tendão envolvido, suas combinações, e se existe a possibilidade de reparo. As lesões irreparáveis do subescapular, assim como as lesões irreparáveis anterossuperiores, podem gerar disfunção do ombro devido à perda dos depressores da cabeça umeral, o que causa dor e limitação funcional. Entre as alternativas terapêuticas estão as transferências miotendíneas, sendo a técnica de transferência do peitoral maior para a tuberosidade menor a mais estudada e difundida nas últimas décadas. No entanto, alguns estudos anatômicos sugerem que o grande dorsal seja uma alternativa mais adequada para o tratamento dessas lesões por apresentar vetores de força mais parecidos com os do subescapular, além de apresentar resultados promissores nas avaliações clínicas de curto seguimento. Este trabalho tem o objetivo de descrever a técnica cirúrgica desenvolvida para transferência do grande dorsal nas lesões irreparáveis do subescapular e anterossuperiores do manguito rotador.
