Relating total hip replacement and acetabular cup positioning with outcome: A systematic review
Ankush Mohabey, Prajakta Warjukar
TL;DR
This study reviews how the positioning of acetabular cups during hip replacement affects outcomes and identifies safe positioning ranges.
Contribution
The paper defines two specific safe windows for acetabular cup positioning to improve surgical outcomes.
Findings
The overall complication rate was 22.2% across 51,308 patients.
Postoperative hip scores showed improved outcomes for patients.
Two safe positioning ranges were identified for acetabular cups.
Abstract
The diverse methodologies employed in assessing cup placement, delineate the recommended target zones for positioning and examine the correlation between cup positioning and occurrences of complications is of interest. We included 51,308 patients and 51,692 hips for this analysis. The overall complication rate was 22.2%. Patients, overall, demonstrated improved outcomes, as evidenced by postoperative hip scores. Two "safe windows" have been defined for surgical procedures: 1) an inclination of 35-50 degrees and an anteversion of 5-25 degrees and 2) an inclination of 35-50 degrees and an anteversion of 15-25 degrees.
