We reviewed 14 patients (16 hips) treated by open reduction and upper femoral derotation osteotomy for congenital dislocation of the hip. Nine patients with 11 treated hips had growth deformities of the proximal femur; in all of them the top screw of the fixation plate lay within the cartilaginous precursor of the greater trochanter. In the five control hips the top screw was more distal. In th...

The authors reviewed eight patients treated with an Ilizarov frame for a non-infected delayed union or non-union after reamed intramedullary nailing of the femoral diaphysis. The hardware was completely removed in all cases but two, in which the distal fragment of a broken nail was left in situ. In five cases without shortening, progressive compression was applied. In the other three patients a...

Since distal femoral varus osteotomy (DFO) -specific plates had not been available in Japan before 2015, we performed DFO using a plate for tibia. The purpose of this study was to elucidate the efficacy and problems associated with the non-specific plate in DFO. We used NCB-PT plates (Zimmer Inc.) in the upside-down position and the minimum 5-year outcomes were evaluated. The mean preoperative ...

BACKGROUND Coxa vara and pseudoarthrosis of the femoral neck after septic hip arthritis is a very rare disease. The aim of this study was to present a case with pseudoarthrosis of the femoral neck, with coxa vara after neonatal septic arthritis of the right hip, and treatment of the pseudarthrosis with proximal femoral valgus osteotomy. CASE REPORT A 12-month-old female, who had suffered neonat...

PURPOSE Three-dimensional (3D) effects of the single plane osteotomies of the proximal femur are compared and analyzed by the trigonometric method. MATERIALS AND METHODS The shape of proximal femur was simplified as a bent line. The bent line is the continuation of the three points-the center of the femoral head, the center of femoral neck at the base, and the center of the femoral shaft. The...

OBJECTIVE : The purpose of this study was to evaluate the performance of valgus intertrochanteric osteotomy in femoral neck non-union. METHODS : Forty-two patients with femoral neck fractures with non-union treated using Pauwels' intertrochanteric osteotomy were reviewed. Demographics, time elapsed between fracture and surgery, follow--up, osteosynthesis used, Garden's classification, limb sh...

BACKGROUND This article reports outcome in osteotomy for malunion of distal radius fractures. MATERIAL AND METHODS We evaluated 12 patients with distal radius malunion (mean age 54), who were treated with corrective osteotomy. Wrist motion and grip strength were evaluated, along with examination of pre and post osteotomy radiographs. The indications for corrections were degree of deformity, l...

BACKGROUND Defining the optimal cutting plane for derotational osteotomy at the distal femur for correction of torsion in cases of patellofemoral instability is still challenging. This preliminary study investigates changes of frontal alignment by a simplified trigonometrical model and demonstrates a surgical guidance technique with the use of femur cadavers. The hypothesis was that regardless ...

OBJECTIVE to review the medical files of 19 patients with a diagnosis of amyoplasia, who underwent percutaneous extensor osteotomy of the distal femur to correct deformities in whom the knees were fixed in flexion. METHODS we analyzed 37 osteotomy procedures on 35 knees that presented an initial deformity in which the knees were fixed in flexion at 33.8°. All of these knees underwent percutan...

During a period of nine years (1982-1991), Pauwels' osteotomy was performed for 38 cases of femoral neck non-:::union:::. 32 led to consolidation with one osteotomy (84%) and 6 failed (3 needed revision (92%), one died and two were lost to follow-up). The length of follow-up was 2-11 years, the average time of non-:::union::: 12 months (ranging from 4 months to 13 years) and the mean patien...
