Valgus Osteotomy of Femur with Debridement of Nonunion Site for Treatment of Nonunion of Femoral Neck

Femoral neck nonunion could be a disaster in young and middle age patients. Conventional valgus osteotomy of femur is done without freshening of nonunion site. We would like to report our experience with valgus osteotomy of hip after freshening of the nonunion site. In a case-series study from all young and middle-aged patients with nonunion femoral neck fracture who were treated with freshninig of nonunion site and valgus ostetomy 22 patients (18 males 4 females) with mean age of 34 (20-47) entered the study. There were 10 broken implants in the heads with a one year follow-up. The cases were evaluated for union necrosis and also changes in Harris hip scores. Preoperative Harris hip score was 63 and postoperative score increased to 89. The neck shaft angle was reached about 150 degrees. In 2 cases necrosis developed and in 3 cases collapse of neck occurred with intrusion of implant into the joint and the implants were removed immediately. Mean time to union was 4.5 months. Freshening of nonunion site before valgus osteotomy in nonunion femoral fracture produces high union rate with low complications.
