Valgus osteotomy in delayed presentation of femoral neck fractures using fixed angle simple dynamic hip screw and plate

Abstract

Purpose: Reduction and fixation in femoral neck fracture in young patients have a problem of nonunion requiring additional procedure like valgus osteotomy but fixation devices are technically difficult for inexperienced surgeons. We aims to assess the results of valgus osteotomy in femoral neck fracture in our setup. Methods: We report a series of 20 patients of higher Pauwel's angled fracture of femoral neck fracture presenting late wherein for valgus osteotomy was added to reduction fixation secured with a commonly available 135° dynamic hip screw and plate. Results: Femoral neck fractures united in 16 patients (80%). Excellent to good results (Harris hip score >80) were seen in 70% patients. Angle of correction of preoperative Pauwels has been changed from 68.3 to 34.3. Conclusion: 135° dynamic hip screw and plate provides rigid internal fixation after valgus osteotomy and being a more familiar fixation device simplifies the procedure with good results.
