Risk Factors of Elbow Stiffness After Open Reduction and Internal Fixation of the Terrible Triad of the Elbow Joint

摘要

Objective To analyze the risk factors of elbow stiffness following open reduction and internal fixation of the terrible triad of the elbow joint. Methods A retrospective study was conducted of 100 patients with the terrible triad of the elbow joint, who had been treated at our hospital from January 2015 to December 2018. All patients were treated with a loop plate to repair the ulnar coronoid process. According to the severity of the injury, the radial head was either fixed or replaced, and the lateral collateral ligament was repaired with an anchor. According to the range of motion of the elbow during the last follow‐up, the patients were divided into two groups. The stiffness group (displayed extension–flexion or pronation–supination ?1?week (OR = 2.714, 95% CI 1.029–7.159, P = 0.044), and postoperative immobilization time (OR = 3.237, 95% CI 1.176–8.908, P = 0.023) were independent risk factors of elbow stiffness after surgery for the terrible triad of the elbow. Conclusion High‐energy injury, the time from injury to surgery??1?week, and postoperative joint immobilization time??2?weeks are the independent risk factors of elbow stiffness after surgery of the terrible triad of the elbow, which should be treated carefully in clinical treatment.
