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.

摘要

GUEPAR(®) 植入物是一种金属双极桡骨头假体，旨在治疗桡骨头粉碎性骨折，当桡腕关节关节面的解剖对线无法实现时。我们在此报告了该植入物罕见的急性完全解体的病例，讨论了这种情况发生的原因，并复习了文献。在本病例中，假体的完全取出提供了满意的结果，在 12 个月的随访中获得了极佳的 Mayo 肘关节功能评分。
