An analysis of 86 case (95 hips) of complex total hip arthroplasty / 中国矫形外科杂志

ABSTRACT

[Objective]To search for a good way for complex total hip arthroplasty(THA) and hip reconstruction.[Method]From February 1995 to June 2007,THA was done 95 hips in 86 patients with good preoperative preparation,full evaluatibn and complete simulation the details occurring at operation.[Result]Eighty one patients were followed up from 6 months to 10 years(average 3.5 years).All patients were measured by Harris score.The preoperative Harris score in the patients ranged from 35 to 50(average 42.1).The postperative score ranged from 70 to 90(average 82.3).Leg length discrepancy ranged from 1 to 12 cm preoperative.(average 4 cm),but from 0 to 5 cm postperative(average 1.5 cm).Two with serious leg length discrepancy,one is 6 cm,the other is 12 cm,after the operation,one is 2 cm,the other is 5 cm.Two had poor incision healing,upper femur split occurred in 3,one with hip prothesis dislocate,nerve injury happened in 2 and two had venous embolism.[Conclusion]Anatomic structure in complex total hip arthroplasty changes so much that it is hard to rebuild and replace a normal hip anatomic structure.Excellent clinical outcome can be achieved with full preparation and evaluation before operation and careful management at opertation.
