Comparison of effects of tantalum rod and allogeneic fibula transplantation in treatment of patients with early non-traumatic osteonecrosis of femoral head during hip-preserving surgery
摘要
Abstract
Objective To investigate the application results of AVN tantalum rod and allograft fibula in young adults with early non-traumatic osteonecrosis of femoral head ( ONFH) during hip-preserving surgery , and to explore the methods for hip-preserving treatment .Methods Seventy-three young patients (80 hips) with early non-traumatic ONFH were ran-domly divided into the tantalum rod group (36 cases, 40 hips) and fibula group (37 cases, 40 hips).The two groups re-ceived hip-preserving surgery , AVN tantalum rod implant and allogeneic fibula transplantation were respectively used to support the femoral head.Harris score, visual analogue scale (VAS) and X-ray staging in the two groups were recorded before treatment and 6, 12, 24, 36 and 48 months after treatment .The efficacy was evaluated and improvement rate was calculated after 48-month treatment in the two groups .The number of cases who needed total hip arthroplasty ( THA) in the two groups was recorded and the successful rate of hip-preserving was calculated .Results Harris scores were higher after treatment in the two groups as compared with those before treatment (all P<0.01).Harris scores of the tantalum rod group were higher than those of the fibula group after 24 and 48 months of treatment (all P<0.01).VAS was decreased in two groups after treatment as compared with that before treatment (all P<0.01).VAS in the tantalum rod group was lower than that of the fibula group after 6, 36 and 48 months of treatment (all P<0.01).As time went on, the progress of femo-ral head was observed under X-ray in two groups after the treatment .Six cases of the tantalum rod group and 7 cases of the fibula group received THA , but no significant differences were found in the improvement rate and the retention rate between the two groups (all P>0.05).Conclusion The effects of AVN tantalum rod and allograft fibula in treatment of young a-dults with early non-traumatic ONFH during hip-preserving surgery are good .Compared with allograft fibula , AVN tantalum rod implant can improve the hip function better and alleviate pain of patients .关键词
