An Extremely Rare Case of Cementless Third Generation Corail Stem Neck Fracture With Fractographic Analysis

Andreja Baljozovic et al. Arthroplast Today. .

Abstract

The cementless Corail stem is one of the most frequently implanted stems and has undergone several design changes. Currently in use is the third generation, named Corail AMT. Until now, only one third-generation Corail stem neck fracture has been described in 2020. In our paper, we present an almost identical complication with an additional analysis of the fracture using a scanning electron microscope. The revision surgery consisted of changing the broken implant with a Corail revision stem, along with replacing the polyethylene liner and the femoral head with new one, after which the patient achieved a full recovery. According to the available literature, this is the second case of this extremely rare complication.

Keywords: Corail stem; Hip revision; Neck fracture.
