The Follow Study Of 100 Cases Of Five Years After Primary Total Hip Arthroplasty

Objective:To evaluate the clinical efficacy,complications and influencing factors of 100 patients undergoing primary total hip arthroplasty(THA)were followed up for 5 years.Method:Following up the 100 patients(123 hips)who were treated with THA by Liuzhou City Workers Hospital Department of Joint Surgery from June 2011 to December 2011.The Follow-up content includes clinical and imaging.Harris score and SF-36 health survey scale were applied in the clinical outcomes in the evaluation of joint function and the quality of life preoperative and postoperative operation.Gruen femoral partition method and DeLee-Chamley acetabulum partition method were adopted in the radiographic result to evaluate femoral prosthesis and acetabulum prosthesis for imaging evaluation analysis.Results:82(99 hips)case were considered valid in this study,of which there were 71 male(86 hips)and 11 female(13 hips),the rate is 82.0%,The average period of visits for each case was 5.2 years(5.0?5.5 years).Harris score increased from an average of 46.82 points(4 to 75 points)to an average of 91.31 points(27 to 100 points)in the last follow-up.Among them,excellent(65 hips),good(19 hips),(10 hips)Hip),excellent rate was 91.7%.SF-36 scale score results:SF-36 PCS increased from preoperative(31.19 ± 9.16)points to(72.96 ± 16.22)points,while SF-36 MCS increased from preoperative(33.50 ±8.50)64.15 ± 11.72)points.Aseptic loosening 3 hips,osteolysis 23 hips,heterotopic ossification 5 hips,claudication 13 cases have been found.What is more,there is no sign of prosthesis dislocation,periprosthetic fractures and infection in this follow-up study.Conclusion:The primary THA patients for the 5 years follow-up overall efficacy satisfaction,the quality of life of patients was significantly improved,but the long-term efficacy still need further follow-up.
