Introduction

Circular external frames (CEF) are commonly used for a wide variety of indications, often when other devices are not appropriate. Circular frames are particularly associated with pin-site infection (PSI). Currently there is a gap in the available literature surrounding the risk of frame use with in-situ prosthetic joints. This retrospective study investigated the incidence of prosthetic joint infection (PJI) in a series of patients with in-situ arthroplasties treated with CEF.

Materials & Methods

From a departmental database of 1052 frames performed from March 2007-March 2023, the outcomes of 34 patients (40 frames) with in-situ arthroplasties at the time of CEF were reviewed (mean follow-up 70 months). Patient identification was by review of all local and regional imaging. The primary outcome was development of PJI during or following CEF and subsequent need for surgical intervention. Secondary outcomes were development of superficial pin site or deep bone infection (without PJI).
