Uncemented hemiarthroplasty was associated with a higher overall risk of reoperation for any reason (HRR 1.5, 95% CI 1.4-1.7, p < 0.001) compared to cemented hemiarthroplasty, with no difference in 1-year mortality (HRR 1.0, 95% CI 0.9-1.0, p = 0.12).

Why the study?

Guidelines recommend cemented fixation for hip fracture arthroplasty in older patients, but inconsistent adherence worldwide requires better characterization of the effects.

Does uncemented bipolar hemiarthroplasty increase the risk of reoperation or mortality compared to cemented hemiarthroplasty in elderly patients with femoral neck fractures?

Population

7539 uncemented and 22,639 cemented hemiarthroplasties for intracapsular femoral neck fractures

Comparison

Uncemented hemiarthroplasty vs cemented hemiarthroplasty

Design

Registry-based cohort study

Follow-up

12 months

Overview

Supports cemented preference in elderly femoral neck fractures; leaves open randomized confirmation.

Structured PICO

Does uncemented bipolar hemiarthroplasty increase the risk of reoperation or mortality compared to cemented hemiarthroplasty in elderly patients with femoral neck fractures?

P
Population
30,178 elderly patients (mean age 84 years, ~71% women) with intracapsular femoral neck fractures undergoing bipolar hemiarthroplasty, registered in the Norwegian Hip Fracture Register from 2005 to 2017.
I
Intervention
Uncemented bipolar hemiarthroplasty
C
Comparator
Cemented bipolar hemiarthroplasty
O
Outcome
Risk of reoperation, mortality rate, and patient-reported outcome measures (PROMs) including pain and quality of life at 12 months postoperativelyhard clinical

Uncemented hemiarthroplasty for femoral neck fractures in elderly patients is associated with a significantly increased risk of reoperation compared to cemented fixation, without differences in mortality or quality of life.
