Mechanical failure of the Coonrad-Morrey linked total elbow arthroplasty: A case report - 29/10/14
Abstract |
Semiconstrained (linked design) total elbow arthroplasty is indicated in a wide variety of cases. Long-term survival is better than with non-linked prostheses. However, mechanical failure of the hinge mechanism is a complication that may occur during follow-up. We report a case of failure of the axle assembly of a Coonrad-Morrey elbow prosthesis 8years after implantation for nonunion of a supracondylar distal humerus fracture. Initial revision surgery included changing the axle and the polyethylene bushings. Revision surgery was necessary 1year later when the axle failed again. A custom-designed locking axle had to be used to stabilize the hinge mechanism. After 3years follow-up, the hinge was intact, there was no loosening of the components and function of the elbow was good.
