RESUMO
[Objective]To compare the short-term clinical effect of Corail entirely hydroxyapatite(HA)-coated versus cemented femoral stem prosthesis in total hip arthroplasty(THA) for elderly femoral neck fracture.[Method]Fifty-four cases of unilateral femoral neck fracture in patient over 75 were retrospectively analyzed from January 2007 to June 2008.In them,21cases underwent THA using Corail femoral prosthesis(HA group),and the other 33 were treated with cemented THA(cement group).The difference was compared in time of hospitalization,time of operation,blood loss,hemodynamic parameters,adverse effect,Harris scoring and radiological results.[Result](1)The average operation time were(52.6?7.2)minutes in HA group and(62.5?8.5)minutes in cement group,with significant difference(P
RESUMO
Objective:To compare the clinical effect of large-diameter metal-on-metal(L-MoM)total hip arthroplasty(THA)versus conventional metal on poly ethylene(MoPE)THA following posterolateral minimal incision.Methods:22 L-MoM THA in 20 patients were performed with posterolateral minimal incision.A matched group of 22 hips in 20 patients who had undergone a MoPE THA with posterolateral minimal incision were also performed by the same surgeon.The two groups of patients were evaluated clinically and radiographically respectively,including the length of the incision,surgical time,intra-operative blood loss,postoperative drainage volume,postoperative amount of decreasing hemoglobin(Hb),postoperative pain score,C-reactive rotein(CRP),erythrocyte sedimentation rate(ESR),the circumference difference of the operated thighs,length of stay,major complications and component positions.Results:There were no differences between the two groups with regard to the length of the skin incision,operating time,blood loss,postoperative amount of decreasing Hb,the visual analog scale(VAS)pain score at 24 hours after surgery,CRP,ESR,the circumference difference of the operated thighs,length of stay,major complications and component positions.Conclusion:L-MoM THA with posterolateral minimal incision can be effectively performed without increased risk of complications.The key is to master the surgical skills.
RESUMO
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.
