Early Results after Treatment of Femoral Neck Fractures with Total Hip Arthroplasty Using Cementless Fiber Metal Taper(R) Stem in Elderly Patients / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the early results of clinicoradiological outcomes after cementless total hip arthroplasty (THA) for displaced femoral neck fracture in elderly patients. MATERIALS AND METHODS: A total of 44 cementless THA procedures performed between January 2008 and January 2012 for displaced femoral neck fracture in patients older than 65 years of age were enrolled in this study and all patients presented normal cognitive ability preoperatively and were followed for more than two years after surgery. We evaluate the clinical and radiological results. The mean age was 72 years (range 65-81 years), 34 patients were female, and 10 patients were male. The mean follow-up period was 30.7 months. RESULTS: Clinically, at the last follow-up, the mean Harris hip score was 96.5 points. Walking ability was recovered postoperatively in 79.5% of cases (35 cases), and activities of daily living were achieved in 66% of cases (29 cases). Radiographically, none of the acetabular cups showed evidence of migration, loosening, or osteolysis. All cases showed excellent or good fixation postoperatively and stable bony fixation of the femoral stem, with the exception of one case, who presented with a periprosthetic fracture during follow-up. There were no cases of osteolysis, significant alignment change or progressive subsidence. Postoperative dislocation occurred in two cases (4.5%), but no re-dislocations were observed after closed reduction. CONCLUSION: Short-term outcomes proved to be satisfactory in elderly patients older than 65 years of age, who presented with normal cognitive ability preoperatively, undergoing cementless THA for displaced femoral neck fractures.
