ABSTRACT
Objective To assess the effectiveness of pedicled iliac periosteal flap graft for treatment of old femoral neck fracture in adolescents.Methods Between June,2005 and December,2013,15 patients (15 hips) of old femoral neck fracture in adolescents treated with vascular pedicled iliac periosteal.There were 11 males and 4 females with an average age of 15.8(range 12 to 18) years.Based on the location of fracture,there was 5 cases of subcapital,8 cases of transcervical and 2 cases of basal.6 cases were treated with lower limb traction,3 cases with internal fixation and 6 just without any treatment.The average duration from injury to the second operation was 4.8 (range 1 to 19) months.There were 2 cases of femoral head necrosis after femoral neck fracture.Open reduction,pedicled iliac periosteal flap grafting and cannulate screw fixation were performed.Results All incisions healed by first intention.All patients were followed up 12 to 90 months (mean,46 months).The HHS was increased from (48.7 ± 8.3) pre-operation to (91.3 ± 6.1) at last followed-up,indicating a significant difference between before and after operation (P ＜ 0.01).One patient underwent total hip arthroplasty at 10 months after operation because of fracture nonunion and femoral head necrosis.Fracture healed successfully in 14 cases and the average time of fracture healing was 4 (range 3 to 6) months.Certain extent of remodelling and bulge of the head were observed in 2 cases of collapsed heads.Conclusion Pedicled iliac periosteal flap graft can provide good osteogenesis and vascular reconstruction for femoral head and promote fracture healing in treatment for old femoral neck fracture in adolescents.
