Abstract

PURPOSE
To evaluate clinicoradiological outcomes after cementless bipoloar hemiarthroplasty in elderly patients with femoral intertrochanteric fractures.
MATERIALS AND METHODS
From March 2006 to February 2008, 28 patients-all in patients greater than 80 years of age, classified unstable intertrochanteric fractures in Evans classification-were followed for more than 1 year. 24 patients were women and 4 patients were men. The mean age of the patients was 84.6 years, the mean follow-up period was 16.3 months. Harris hip score, postoperative inguinal and thigh pain, Parker and Palmer mobility score were analyzed clinically. The radiological results were assessed using various radiological indicies including bone-union, fit and alignment change of femoral stem and vertical subsidence.
RESULTS
The average Harris hip score was 82.9, Parker and Palmer mobility score preoperative 8.0 changed to 5.2 postoperatively. More than moderate pain was presented in 1 case. There were no cases of varus deformity or osteolysis. All stems were stable without significant alignment change or subsidence except 1 case of periprosthetic fracture. There were no dislocation, thromboembolism, death during operation or hospital days.
CONCLUSION
In elderly patients, cementless bipolar hemiarthroplasty is good treatment method of unstable intertrochanteric fracture and short-term clinicoradiological outcomes proved to be satisfactory.
