title: Double intertrochanteric osteotomy for trochanteric overgrowth and a short femoral neck in adolescents.
abstract: To review the outcome of Wagner double intertrochanteric osteotomy for trochanteric overgrowth and a short femoral neck in 7 adolescents.
  
  
  
  Records of one male and 6 females aged 15 to 20 years who underwent modified Wagner osteotomy for trochanteric overgrowth and a short femoral neck by a single senior surgeon were reviewed. The diagnoses were coxa vara (n=2), developmental dysplasia of the hip (n=3), Leg-Calve-Perthes (n=1), and proximal femoral focal deficiency (n=1). Radiological indication for double intertrochanteric osteotomy included a neck-shaft angle (NSA) <120º or a centre trochanter distance (CTD) <28 mm. Function was evaluated using the Children's Hospıtal Oakland Hip Evaluation Scale (CHOHES). The articulotrochanteric distance (ATD), CTD, NSA, and the distance between the centre of the femoral head and the centre of the acetabulum (MZ) were measured on radiographs.
  
  
  
  The mean follow-up duration was 61 (range, 28-86) months. The ATD improved from 16±11.5 mm to -6.3±10.2 mm (p=0.018), the CTD from 27.9±3.5 mm to 36.4±7.1 mm (p=0.018), the NSA from 112º±24.4º to 131º±16º (p=0.028), the MZ from 12.7±6.5 mm to 7.7±4.2 mm (p=0.028), and the CHOHES score from 62.1±8.7 to 84±9.6 (p=0.017). One patient had delayed union. Two patients had persistent Trendelenburg gait. Two patients declined second-stage surgery for acetabular dysplasia after solving the femoral side problems at the first stage. One of them developed hip arthrosis.
  
  
  
  Double intertrochanteric osteotomy is a viable treatment option for adolescents with trochanteric overgrowth and a short femoral neck.
