Traumatic divergent dislocation of the elbow in the adults

Abstract

Purpose This retrospective study aimed to investigate the clinical outcomes of DDE in adults. Methods From September 2010 to March 2020, adult patients with traumatic DDEs admitted to Beijing Chaoyang Hospital and Beijing Jishuitan Hospital were included in this study. Each patient underwent operative or conservative treatment during hospitalization. The clinical and radiological examinations were followed up. The primary outcomes included the Mayo Modified Wrist Score (MMWS), the Mayo Elbow Performance Score (MEPS), the Broberg and Morrey functional index, the Disabilities of the Arm, Shoulder and Hand (DASH) score, and the Visual Analogue Scale (VAS) score that were performed. Post-operative complications and secondary surgery details were also collected. Results Of the fourteen patients, clinical and radiographic results were reviewed at a mean of 53.2 months (18 to 110 months) postoperatively. There were 11 men and three women with an average age of 31.5 years (17 to 51 years). At the final follow-up, the average MMWS, MEPS, Broberg and Morrey functional index, and DASH scores were 91.4 points, 93.4 points, 92.6 points, and 10.7 points. The mean VAS at rest and during activities was 0.4 and 1.7 points. Two patients required a secondary procedure due to radial malalignment and elbow contracture, respectively. In addition, two patients were found degeneration. Conclusions Within the context of high-energy DDE combined with simultaneous upper limb injuries, our study recommended obtaining the mechanical benefit of the forearm ring with concentric elbow stability. Despite the various and complicated traumatic patterns of DDE, great clinical results could be acquired based on adequate surgical treatments and early rehabilitation training.

“…Injuries to the elbow, forearm and wrist account for approximately 25% of all sports-related injuries. Children and healthy adults are usually prone to different elbow injuries 11 .Elbow dislocation can also be seen in falls from heights 13 , trampoline in the pediatric population 14 , traffic and machine accidents 15 , and lifting and moving heavy parts.…”

Investigating Elbow Dislocation and Instability: A 3D Finite Element Analysis Approach

“…Among other joints, the elbow is the most frequently dislocated in children and the second most frequently dislocated in adults, after the shoulder [5]. Elbow injuries can be seen in sports [4,6,7] and other accidents like falls from heights [8], and traffic and machine accidents [9]. Elbow dislocations can affect the hand's motion and functionality and result from injury mechanisms associated to high energy impacts like falling onto an outstretched hand [10].…”
