Abstract:
Objective To analyze retrospectively the clinical efficacy that the application with vascularized greater trochanter to reconstruct the collapse of femoral head necrosis.Methods Followed-up the data of 21 patients who underwent reconstruction of the femoral head from January,2008 to December,2012,by this we made the clinical and radiological assess,Harris hip scoring system was used to evaluate the situation of hip function.All patients were followed up regularly for X-ray film (after 3 months,6 months and then be reviewed once a year),by the film we assessed the bone healing and repair of the femoral head,and determined whether had the progress in phases.The clinical survival was decided by receiving or not the arthroplasty.Results All 21 patients were followed up for 24-72 months,with an average of 47 months.The postoperative Harris hip score was 82.8 ± 7.1 points,compared with the preoperative,the score improved significantly (average 52.4 ± 4.3 points for preoperative),the difference was statistically significant (P ＜ 0.05).Based on Ficat stage for osteonecrosis,8 patients in this group had progress after 24 to 48 months (mean 33 months),whose femoral heads got collapse worsened.The radiographic success rate was 61.9％.Six cases received arthroplasty in 18 to 48 months (mean 34 months) due to progressive collapse of the femoral head or severe hip pain,or both.FicatⅢ contained 25％ (4 hips),and Ⅳ had 40％ (2 hips),the clinical survival rate was 71.4％.Conclusion The application with vascularized greate.r trochanter transfer coverage to rebuild the collapse of the femoral head in patients with osteonecrosis is a good way.It' s worthy to be applied.
