RESUMO
OBJECTIVE: To compare postoperative radiographic outcomes of Schatzker type V and VI tibial plateau fractures treated with double-plate or single lateral locked plate. METHODS: Sixty-three patients operated from December 2011 to February 2016 were selected, 47 from the double-plate group and 16 from the single lateral locked plate group. Minimum follow-up for all patients was 6 months. Fracture reduction evaluation was based on radiographic parameters: joint reduction, sagittal alignment, coronal alignment, and condylar width. RESULTS: Radiographic evaluation showed no statistical difference in the immediate or late postoperative periods. CONCLUSION: Despite the reduced sample, this study is aligned with current results published in the medical literature. The severity of Schatzker type V and VI tibial plateau fractures can be minimized by the correct indication for the implant regarding fracture morphology. Level of Evidence III, Retrospective comparative study.
OBJETIVO: Comparar desfechos radiográficos pós-operatórios de fraturas do planalto tibial Schatzker V e VI tratados com dupla placa ou placa bloqueada única lateral. MÉTODOS: Foram selecionados 63 pacientes operados no período de dezembro de 2011 a fevereiro de 2016, sendo 47 do grupo dupla placa e 16 do grupo placa bloqueada lateral única. Todos os pacientes tiveram seguimento mínimo de seis meses. A avaliação da redução das fraturas foi baseada nos parâmetros radiográficos: redução articular, alinhamento sagital, alinhamento coronal e largura condilar. RESULTADOS: A avaliação radiográfica não demonstrou diferença estatística no pós-operatório imediato nem no tardio. CONCLUSÃO: Apesar da amostra reduzida, o estudo vai ao encontro dos resultados mais atuais publicados na literatura médica. A gravidade das fraturas do planalto tibial Shatzker V e VI pode ser minimizada com a correta indicação do implante segundo a morfologia da fratura. Nível de Evidência III, Estudo retrospectivo comparativo.
RESUMO
INTRODUCTION: According to Fraser's description, ipsilateral femoral and tibial diaphyseal fractures are characterised as type I floating knee and have a better prognosis than fractures with joint involvement (type II). There are few reports of functional and muscle strength in these patients. The objective of this study was to evaluate the functional and isokinetic muscle strength of patients with type I floating knee undergoing femoral and tibial internal fixation. METHODS: Patients with type I floating knee undergoing concomitant femoral and tibial internal fixation were invited for clinical evaluation. The parameters evaluated included the following: Karlstrom and Olerud score; Lysholm score; isokinetic thigh and hip muscle evaluation; knee range of motion; pain level; investigation of associated knee injuries by clinical evaluation and MRI; and types of complications. RESULTS: Twenty-one patients were included in the study; 11 of these were clinically evaluated, with a mean follow-up of 23.9 months. Six patients had an acceptable result according to the Karlstrom criteria, whereas eight patients had a poor result based on the Lysholm scale. The peak torque deficit was 61% for knee extensors, 37% for flexors and -9% for hip abductors. The mean pain level was 5.9. Three patients had a partial anterior cruciate ligament (ACL) injury; one patient had a posterior cruciate ligament (PCL) injury; and three patients had a meniscal injury. There were four cases of tibial or femoral nonunion at one year and two cases of chronic osteomyelitis. CONCLUSION: Patients with type I floating knee had unsatisfactory functional results, significant knee extensor and flexor muscle strength deficits and a significant rate of complications at the two-year follow-up.
