title: Acute disassembly of a bipolar radial head arthroplasty.
abstract: The GUEPAR(®) implant is a metallic bipolar radial head prosthesis designed to treat comminuted radial head fractures when anatomic realignment of the articular surface of the radiocapitellar joint is not possible. We report herein the rare case of an acute complete disassembly of this implant, discuss the reason for this occurrence and review the literature. In the presented case, the complete removal of the prosthesis provided a satisfactory outcome with an excellent Mayo Elbow Performance Score at 12months follow-up.
