Functional Outcome of Uncemented (Hydroxyapatite Coated) Bipolar Hemiarthroplasty in Fracture Neck of Femur in Elderly

TL;DR

This study shows that a specific hip surgery for elderly patients with femur fractures leads to good recovery and mobility.

Contribution

The study evaluates the functional outcomes of uncemented hydroxyapatite-coated bipolar hemiarthroplasty in elderly patients.

Findings

The mean Harris Hip Score at nine months was 88.4 ± 9.2.

66% of patients had excellent functional outcomes, and most regained independent ambulation.

Complication rates were low, with only 5% classified as poor outcomes.

Abstract

Femoral neck fractures in the elderly are associated with high morbidity and reduced mobility. Uncemented hydroxyapatite-coated bipolar hemiarthroplasty is increasingly used to avoid cement-related complications. This study evaluated postoperative functional outcomes using the Harris Hip Score (HHS).

A prospective observational study was conducted on 38 elderly patients (≥65 years) with displaced intracapsular femoral neck fractures who underwent uncemented hydroxyapatite-coated bipolar hemiarthroplasty. Functional outcome was assessed using the Harris Hip Score at nine months. Descriptive statistics (mean ± SD) were used.

The mean Harris Hip Score at nine months was 88.4 ± 9.2. Outcomes were classified as excellent in 25 patients (66%), good in 7 (18%), fair in 4 (10%), and poor in 2 (5%). Most patients regained independent ambulation with minimal complications.

Uncemented hydroxyapatite-coated bipolar hemiarthroplasty provides satisfactory early functional outcomes in elderly patients with femoral neck fractures, with high HHS scores and low complication rates over nine months.
