Abstract:
Objective To evaluate the effects of hydroxyapatite (HA) extensively-coated prosthesis on elderly patients undergoing hip arthroplasty.Methods From February 1997 to May 1999,96 patients Were treated with hydroxyapatite (HA) coated prosthesis and followed up for their hip arthroplasty.Their results were studied clinically and roentgengraphically to evaluate chiefly their Harris scores,complications and thigh pain.The survival of prosthesis was evaluated according to Kaplan-Meier methods.Results The 60 cases were followed up for eight years on average(range,sevon to nine years).Their mean Harris scores were improved from 42 preoperatively to 90 postoperatively.Fifty-eihgt cases felt no pain at their hip,but two did at their thigh.No radiolucent lines were observed.All the prostheses achieved bony stabilization and remolding.Conclusions HA coated prosthesis can achieve fine fixation,because it helps bone conduction,resists axial force and torsion,and reduces operative risks.
