Abstract:
Objective:To observe the application effect of minimally invasive decompression,bone graft implantation and metal trabecular bone reconstruction system for early stage osteonecrosis of femoral head and discuss the treatment of hip salvage operation in early stage osteonecrosis of femoral head. Methods:From January 2010 to June 2011,50 patients(62 hips)which were osteonecrosis of femoral head of early stage,were treated with minimally invasive decompression,bone graft implantation and metal trabecular bone reconstruction system,including 31 males(40 hips),19 females(22 hip)with an av?erage age of 36.2 years old ranging from 22 to 54 years old. The course of disease was from 6 to 15 months(averaged 10.5 months). Among them,19 cases(23 hips)were steroid induced,25 cases(33 hips)were alcohol induced,6 cases(6 hips) were idiopathic;According to ARCO stage,28 hips were at stageⅠ,34 hips were at stageⅡ. All of them were diagnosed as femoral head necrosis by imaging examination before operation. Then each patient was followed to assess by Harris hip score , curative effect,and conduct the femoral head survival analysis during the postoperation. Results:All patients had finished op?eration,the operation time was between 30 and 85 min,intraoperative blood loss was 50 to 220 ml,and 47 cases(58 hips) were follow up from 24 to 46 months with an average of 34.05 months. As compared with preoperative,the Harris hip score at the last follow up was improved,the difference was statistically significant(P<0.01). The Harris hip score,curative effect and survival time of femoral head in ARCO stageⅠwas superior to these in ARCO StageⅡ,the difference was statistically signif?icant(P<0.05). Conclusion:Effect of minimally invasive decompression,bone graft implantation combine with the metal tra?becular bone reconstruction system for early stage osteonecrosis of femoral head was good,it could significantly improve the Harris hip score,increase the femoral head survival time,delay the hip replacement,and performance better in ARCO stageⅠ.
