Unilateral hinged external fixation frame for elbow compression arthrodesis: the stepwise attainment of a stable 90-degree flexion position: a case report

We report a case of an elbow arthrodesis using a modular hinged external fixation device in a patient who sustained a complex high-energy injury. The extensive bone and soft-tissue loss and local infection precluded restoration of the articular anatomy. Other reconstructive options, including total elbow arthroplasty and allograft reconstruction, were not appropriate in this clinical situation. A transelbow hinged external fixator was applied with the elbow in extension. Subsequently, the hinge was brought gradually into 90 degrees of flexion as the elbow fused. Fixation and arthrodesis were successfully achieved by using this modular device, despite severe tissue loss and local septic complications. Furthermore, by gradually flexing the frame from full extension to 90 degrees , the need for flap coverage of the open wound was avoided.
