Treatment of Early Femoral Head Avascular Necrosis by Core Decompression Combined with Artificial Bone Support Rods and Autologous Iliac Bone Mixed with PRP
Abstract：Objective To investigate the efficacy of nanocrystalline collagen-based artificial bone support combined with allogeneic bone grafting in the treatment of early femoral head necrosis in adults.Methods From August 2015 to January 2017，19 patients with early femoral head necrosis (Steinberg stage I~Ⅱ) were treated with core decompression combined with nanocrystalline collagen-based artificial bone support rods and autologous iliac bone implanted with PRP in our hospital，including 18 cases on one side and 1 case on both sides.There were 14 males and 5 females.The progress of osteonecrosis and the collapse of the femoral head were observed.Comparing the changes of Harris hip score before and after surgery.The radiographic evaluations were performed at 1，6，12 months postoperatively with pelvic radiographs，to observe the femoral head repair and necrosis.Results All patients were followed up for 12 months after surgery.Harris scores were performed 12 months postoperatively.The statistical results showed that there was a significant difference between preoperative and postoperative Harris scores.According to the Harris scoring system，there were 14 excellent hips，3 good hips，2 not bad hips，and 1 poor hip，in this group of 20 hips.The excellent and good rate was 85％.One patient still had hip pain after surgery.The results of radiographs showed that 3 hips showed imaging progress，and imaging changes were consistent with clinical symptoms and signs of patients.Conclusion Core decompression combined with nanocrystalline collagen-based artificial bone support rods and autologous iliacbone implanted with PRP for the treatment of early femoral head necrosis is suitable for young patients with femoral head necrosis，which is of great significance for relieving hip joint pain，restoring joint function and postponing total hip arthroplasty.
