# Acetabular Management in Hip Hemiarthroplasty: Reaming Considerations and Current Evidence

## TL;DR

This paper reviews the role of acetabular reaming in hip hemiarthroplasty and suggests it should be used selectively to avoid harming cartilage and bone.

## Contribution

The paper provides a synthesis of clinical and biomechanical evidence to guide individualized acetabular reaming decisions in hip hemiarthroplasty.

## Key findings

- Routine acetabular reaming does not consistently improve patient or radiographic outcomes.
- Acetabular reaming may compromise cartilage and bone preservation.
- Targeted reaming should be reserved for cases with unstable acetabular anatomy.

## Abstract

Acetabular reaming during hip hemiarthroplasty is practiced inconsistently across surgeons and institutions, yet its benefits and risks remain uncertain. We reviewed the clinical and biomechanical literature addressing acetabular preparation in hemiarthroplasty, including evidence related to implant seating, acetabular wear, pain, function, and later conversion to total hip arthroplasty. Across the available studies, routine reaming did not demonstrate consistent improvement in patient-reported and radiographic outcomes and may compromise cartilage and bone preservation. The decision to ream should be individualized, reserving limited, targeted reaming for cases in which acetabular anatomy prevents stable seating, while prioritizing cartilage preservation in typical fracture patients.
