- W1679468363 abstract "Objective To observe the clinical and radiographic outcomes following the THA using a hydroxyapatite-eoated anatomic stem. Methods From 2001 to 2003, 90 total hip arthroplasty were per-formed in 75 patients using a hydroxyapatite-coated anatomic stem. There are 49 males and 26 females, with the mean age of 58.4 years, range from 42 to 68 years. The mean follow-up period was 7.2 years (5 to 8 years). All patients were evaluated clinically using Harris hip score; preoperative and follow-up radiographs were made. Results Forty-eight patients with 56 hips were involved in this study. There were 29 males and 19 females were included. No patients had underwent revision arthroplasty or aseptic loosening. Accord-ing to the Harris hip score, the average hip score increased from 28.23=6.3 before operation to 93.23±4.8 one year after operation and to 91.6±4.5 at the final review. There was significant difference between the Harris scores at final review and preoperative ones, but no difference one year after operation. All patients had ex-cellent or good results. Three cases were found to be associated with thigh pain. All prostheses were well os-seointegrated. Limited proximal femoral osteolysis occurred in two cases, three cases had radiographic evi-dence of osteosclerosis on the tip of the stem, and six cases were found to represent discontinuous radiolu-cent lines surrounding the stem on the radiographs. No stem subsidence and varus/valgus happened. Con-clusion Hydroxyapatite-coated anatomic stem provided favorable clinical and radiographic results after an intermediate duration of follow-up. The prosthesis had achieved reliable bone ingrowths. The long-term re-sults is needed to be confirmed in future.Key words: Arthroplasty; replacement; hip; Hip prosthesis; Hydroxyapatites" @default.
