What Might Prevent Me From Extending My Elbow All the Way?

Problems with fully straightening your elbow can be caused by stiffness from an injury, inflammation in the joint, or other causes.

Explanation

Difficulty extending your elbow fully may be due to elbow stiffness. This condition often develops after injuries like dislocations or fractures that damage normal joint movement. As the injury heals, scar tissue can develop inside the elbow, limiting smooth motion. Additionally, the muscles, tendons, and ligaments around the joint can tighten or become inflamed—as seen in tendinitis—which restricts movement. Arthritis and other inflammatory conditions in the joint can also limit how far you can extend your elbow. Sometimes the ulnar nerve can become entrapped as it passes through the elbow causing tingling, numbness, and limited movement. This nerve compression, known as cubital tunnel syndrome, can make it difficult to fully straighten the arm. Additionally, bony growths (osteophytes) from conditions like osteoarthritis can physically block complete elbow extension. Consultation with a healthcare professional can help identify the underlying cause of joint stiffness.
