Outcomes of Hemiarthroplasty and Total Hip Arthroplasty for Femoral Neck Fracture: A Medicare Cohort Study.

ABSTRACT:

Objectives

For patients with femoral neck fractures, total hip arthroplasty (THA) demonstrates superior outcomes compared with hemiarthroplasty. However, hemiarthroplasty remains a common treatment for femoral neck fractures and the conversion rates are unknown. We compared the results of the 2 procedures using a Medicare database.

Methods

We assembled a cohort of 70,242 patients 65 to 90 years of age with an ICD9 diagnosis and matching Current Procedure Terminology code for femoral neck fracture between 2008 and 2012. Patients were followed forward for 2 years minimum. Incidences of dislocation and mortality were measured. Reoperation for revision of THA or conversion of hemiarthroplasty to THA was assessed by Current Procedure Terminology code. Groups were compared through
