Abstract:
Objective:To evaluate the short-term results of total hip arthroplasty(THA)with entirely Corail hydroxyapatite(HA)-coated prosthesis in the treatment of femoral neck fractures in the elderly patients.Methods:A total of 21 cases of primary THA from Jan 2007 to Jun 2008 using Corail prosthesis in the treatment of the femoral neck fractures in elderly patients were reviewed.Their results were studied clinically and roentgen graphically to evaluate chiefly their Harris scores,complications and thigh pain.Results:All patients were in good condition during the operation.The mean operation time and average bleeding volume during operation was(52.6 ?7.17)min and(217.9?37.7)ml,respectively.Except 2 patients with deep venous thrombosis,2 patients with fat necrosis and 5 patients with cognitive impairment,there were no serious complications occurred.The postoperative X-ray films showed that the initial fixation was excellent or good in all the stems.A total of 19 cases were followed up for 9.5 months on average.No thigh pain was seen in these cases.Their mean Harris scores were improved from 37.2?6.7 preoperatively to 83.5?4.8 postoperatively.X-ray examination showed no radiolucent lines,osteolysis,or loosing of prosthesis.Subsidence of prosthesis was found in 2 cases,however,with a distance less than 2 mm.All the prostheses achieved bony stabilization according to the criteria proposed by Engh et al.Conclusion:The THA for elderly femoral neck fracture with Corail entirely HA-coated prosthesis has an excellent clinical and radiological short-term results and meanwhile is safe.
