What joint motion is commonly not fully restored after a dislocation of the elbow?

• A. Flexion
• B. Extension
• C. Pronation
• D. Supination

Answer: (B)

Following an elbow dislocation, it is common for the restoration of the extension motion to be incomplete. This is often due to several factors such as joint capsule injury, damage to the surrounding ligaments, and potential involvement of nerve structures, particularly the ulnar nerve, which can be stretched or damaged during the dislocation. Loss of structural integrity in the soft tissues can subsequently lead to limited range of motion. While flexion, pronation, and supination may also be affected after an elbow dislocation, extension is particularly notorious for being compromised. In some cases, patients may experience stiffness or develop post-traumatic elbow stiffness, leading to further limitations specifically in their ability to fully extend the elbow. Therefore, when assessing the outcomes of an elbow dislocation, the restoration of extension is notably challenging and frequently does not return to pre-injury levels.
