Acute elbow dislocation: a critical appraisal of the literature

Abstract

Background: The purpose of this study was to perform a narrative review of acute elbow dislocation (AED). There are certain aspects of the management of AED that are controversial, including type and length of immobilization, indications for surgery, type of surgery, and new evidence available. Material and methods: A literature search was performed using MEDLINE and Embase databases for studies regarding AED. Preference was given to studies according to their level of evidence. Studies regarding the outcome of conservative and surgical treatment, including patient-reported outcomes, complications, and conversion to stabilization or revision surgery were included. Results: We found only 1 level I study and 3 level II randomized clinical trials. The rest consisted of level III-V evidence. Conservative care continues to be the standard of care for stable AEDs. Shorter immobilization periods are favored when possible. A consensus definition of an unstable elbow still needs to be improved. Unstable simple elbow dislocation may benefit from surgical intervention with different techniques showing similar outcomes. Advances in surgical procedures and suture designs, including tapes, and ligament augmentation, need to prove their role in managing acute elbow instability. Conclusion: There is a need for higher quality studies after the reduction of an AED, including discerning the outcome of specific patterns of injury and particular groups of patients like high-level athletes or people with preoperative laxity. Comparison between different surgical techniques is warranted, including arthroscopic techniques and types of ligament augmentation to promote early motion and reduce postoperative stiffness.
