Significant Clinical Improvement After Trochanteric Transfer (Mean 6-Year Follow-Up)

Abstract

Objectives: Premature closure of the proximal femoral physis may occur as a sequel to the treatment of Perthes disease, slipped capital femoral epiphysis, septic arthritis and developmental dysplasia of the hip. The discontinuation oflongitudinal growth in the proximal femoral physis and the continued growth of the trochanter result in a short femoralneck and a relatively enlarged great trochanter. Decrease in the articulotrochanteric distance may lead to shorteningof the adductor force arm. Therefore, positive Trandelenburg's sign can be seen in patients secondary to a decrease inabductor function. The main objective in trochanteric transfer surgery is to increase the abductor force arm to eliminatethe disruption and to improve hip functions. We have aim to evaluate clinical and radiological results of trochanterictransfer surgery.Methods: 8 patients who underwent trochanteric transfer surgery between June 2011 and June 2014 were evaluatedretrospectively. Age, gender, skeletal maturity status at the time of surgery, additional surgeries, side, postoperativefollow-up time and symptom duration has recorded. Range of motion degrees of hip, abductor muscle strength, leglength discrepancy and Harris Hip Score(HHS) has measured both preoperative and postoperative period. Radiologicalevaluations were made on posteroanterior pelvis and lateral hip radiographs.Results: The mean age of the patients was found to be 17.63 (13–32 years) at the time of surgery. Patients were followed for at least 36 months. The mean follow-up period was 74.75 months (36–92 months). There was a statisticallysignificant chance in HHS (p
