Application of extended trochanteric osteotomy in hip joint revision / 中国矫形外科杂志

ABSTRACT

[Objective] To study the application and clinical result of extended trochanteric osteotomy in hip joint revision.[Methods]Thirteen hips in 13 patients who were treated with extended trochanteric osteotomy in hip joint revision from 2003 to 2007 were followed-up for an average time of 32.3 months.The revision reasons,Harris score,osteotomed length,and the oeteotomed union time were analyzed.[Results]The average preoperative Harris score of all patients was 38(24~68),the average postoperative Harris score was 77(57-100),with the improvement of 39 points.The average osteotomed length from the tip of great trochanter to distal osteotomy site was 12.4 cm(9~15.1 cm).The osteotomy sites were healed in 11 patients at 3 months and 2 patients at 6 months after operation.[Conclusion]Extended trochanteric osteotomy is useful in hip joint revision.After osteotomy femoral prosthesis and cement could be taken out easily,and the osteotomy site could be healed easily.
