Does femoral stem choice associate with survivorship and clinical outcomes after conversion total hip arthroplasty? A retrospective analysis and novel treatment algorithm.

ABSTRACT:

Background

Conversion total hip arthroplasty (cTHA) after prior proximal femoral fracture fixation can be performed using different femoral stems. This study aimed to (1) determine if initial fracture fixation or pattern associated with stem design in cTHA, (2) evaluate whether stem type was associated with survivorship and outcomes, and (3) propose a radiographic measurement to guide femoral stem selection.

Methods

We retrospectively reviewed 51 patients who underwent cTHA from 2016 to 2020, including 44 patients with previous cephalomedullary nail (CMN; 86.3%) and 9 patients with previous sliding hip screw (SHS; 13.7%). Stems included 32 uncemented diaphyseal-engaging (62.7%), 10 uncemented metaphyseal-engaging (19.6%), and 9 cemented (17.6%). Outcomes assessed were fractu
