A Short-term Clinical Study Of The Corail High Femoral Offset Stem Prosthesis In Total Hip Arthroplasty

Objective: To evaluate the short-term results of the Corail high femoral offsetstem prosthesis in total hip arthroplasty.Methods: A total of37patients40cases of primary THA from April2009toAugust2012using Corail high femoral offset stem prosthesis, which were made bythe DePuy company in the USA,were reviewed. Their results were studied clinicallyand roentgen graphically to evaluate chiefly their Harris scores and complications.Results: All patients were in good condition during the operation. The meanoperation time and average bleeding volume during operation was54.8±7.24minand245.6±38.2ml. Except1patients with deep venous thrombosis and1patientswith fat necrosis,there were no serious complications occurred. Their femoral offsetwere improved from34.78±7.34㎜preoperatively to43.46±6.12㎜postoperatively and mean Harris scores were improved from34.4±5.7preoperatively to84.5±5.3postoperatively. The reconstruction rate of theacetabulum rotating center was82.5%and the reconstruction rate of the lower limblength was87.5%. The postoperative X-ray films showed that the initial fixationwas excellent or good in all the stems.A total of37patients40cases were followedup for12±4.7months on average. All the prostheses achieved bony stabilizationaccording to the criteria proposed by Engh et al.Couclusiou: The Corail high femoral offset stem prosthesis is fit for the patientwhose lower limb femoral offset is large in total hip arthroplasty and it can be fixedfirmly. It can rebuild femoral offset, acetabulum rotating center, lower limb length, and restorethe stability of the hip joint.
