RESUMO Objetivo: Avaliar escores de joelho, resultados da avaliação radiológica, correção de déficits, alteração da altura patelar, tempo de consolidação óssea e tempo para apoio de peso no pós-operatório em pacientes submetidos à osteotomia tibial alta (OTA) com ou sem enxerto autólogo de osso ilíaco. Métodos: O exame retrospectivo de controles tratados em estudo randomizado e controlado foi realizado em 63 joelhos de 58 pacientes com idade entre 46 e 59 anos submetidos a OTA com placas bloqueadas de titânio em cunha aberta. Os pacientes foram divididos em dois grupos: Grupo A, OTA com enxerto de osso ilíaco autólogo (n = 31) e Grupo B, OTA sem enxerto autólogo de osso ilíaco (n = 32). Os dados clínicos e radiológicos foram avaliados prospectivamente na consulta pré-operatória e 6, 9 e 12 semanas e 6 meses e 1 ano após a cirurgia (e depois disso, anualmente). Resultados: Não houve diferenças significativas quanto a avaliação radiológica, correção de déficit, mudança de altura da patela, tempo de cicatrização óssea e tempo para apoio de peso entre os dois grupos em nenhum momento após a cirurgia. Os escores de joelho mudaram positivamente em ambos os grupos (p < 0,001). Conclusões: Não houve diferença nos resultados dos pacientes submetidos a OTA com placas bloqueadas de titânio em cunha aberta com e sem autoenxerto, e as comorbidades resultantes dos autoenxertos foram eliminadas com o uso de placas bloqueadas. Nível de Evidência III, Estudo Retrospectivo.

ABSTRACT Objective: To postoperatively evaluate knee scores, radiological assessment results, deficit correction, patellar height change, bone healing time, and weight bearing time in patients undergoing high tibial osteotomy (HTO) with/without autologous iliac bone grafting. Methods: This retrospective examination of treated controls from a randomized controlled study included 63 knees of 58 patients aged 46–59 years who underwent HTO with locking open wedge osteotomy plates. The patients were divided into two groups: Group A, HTO with autologous iliac bone grafts (n = 31); and Group B, HTO without autologous iliac bone grafts (n = 32). Clinical and radiological data were evaluated prospectively at the preoperative consultation and again at 6, 9, and 12 weeks, 6 months, and 1 year after the surgery (and annually thereafter). Results: There were no significant intergroup differences in the radiological assessment, deficit correction, patellar height change, bone-healing time, and weight-bearing time at any time after surgery. The knee scores changed positively in both groups (p < 0.001). Conclusions: There was no difference in the results of patients undergoing HTO with open wedge osteotomy titanium locking plates with or without autografting, and comorbidities resulting from autografts were eliminated with the use of locking plates.

ABSTRACT Objective: The aim of this study was to investigate whether haemogram parameters are predictive factors for both the severity of the disease and a decision in favor of surgical treatment in patients with an established diagnosis of cubital tunnel syndrome (CuTS) . Methods: The medical files of patients with a diagnosis of CuTS who were followed-up conservatively (n=92) or surgically treated (n=92) were retrospectively screened and the haemogram parameters were recorded . Results: The receiver operating characteristic (ROC) curve analysis revealed an area of 0.665 under the curve, with 76.3% sensitivity and 84.8% specificity at the cut-off of a red cell distribution width (RDW) level grater than 15.45%. RDW levels higher than 15.5%, electromyography (EMG) severity, and a clinical score higher than three were found to be independently associated with surgery . Conclusion: An elevated RDW value was related to the severity of the electromyogram. RDW may, therefore, be a useful independent predictor for the decision to surgical treatment of CuTS.

Objective:To evaluate the effectiveness of intramedullary fixation using the Kirschner-wire (K-wire) compared to the titanium elastic nail (TEN) in pediatric femoral shaft fractures.Methods:A sample of 42 pediatric patients with a mean age of 6.55±2.42 years (range 4-11 years) presenting femoral shaft fractures underwent intramedullary fixation using the K-wire or TEN.Results:There was no significant difference found between groups, of which 16 (38.1%) patients were treated with K-wire and 26 (61.9%) patients were treated with TEN in terms of union duration. Moreover, none of the patients showed nonunion or a delayed union.Conclusions:The use of adjusted K-wire instead of TEN in the intramedullary fixation of femoral shaft fractures in selected children may be an advantageous surgical option due to the lower cost, easy accessibility and no need for a second surgery for implant removal.
