Evaluation of treatment of fracture neck femur with uncemented HA coated modular bipolar prosthesis

Abstract

Background: Background: Fracture of the femoral neck has been reported with increasing incidence in recent times due to prevalence of osteoporosis. Uncemented HA coated modular bipolar hemiarthroplasty systems provide a customised press fit solution which improve the patient outcome with respect to limb length discreptancy. We report our series of 15 cases of fracture neck of femur operated over years with modular cementless HA bipolar hemiarthroplasty. Methods: 15 patients (age=50 to 70 years) with displaced femoral neck fractures were operated between January 2019 to December 2019. Cementless HA coated modular bipolar hemiarthroplasty using hydroxyapatite coated stem was done by single surgeon using same implant in all the patients through Moores approach. Clinical and radiological follow-up was done. Results: Total 15 cases with fracture neck femur were operated. The average follow up was 48 months. No intraoperative mortality was seen. 1 patient had calcar fracture of femur during canal preparation. 1 patient had delayed transient sciatic nerve palsy, and 1 patient had insignificant limb length discripency (0.5 cm). 12 patients reached to pre-injury status with average harris hip score of 88 at final follow up. Conclusions: Cementless bipolar hemiarthroplasty with hydroxyapatite coated stem is a good option for femoral neck fractures in elderly patients.
