An elbow dislocation happens when the forearm bones are forced out of alignment with the upper arm, usually after a fall onto an outstretched hand. Dislocations are grouped as simple, no fracture, or complex, with one or more fractures of the radial head, coronoid, or olecranon.
The elbow is unusually prone to stiffness after injury, so the modern approach favors restoring stability and then beginning motion early rather than long immobilization. The right balance depends on whether the joint is stable after reduction and whether fractures are present.
Simple versus complex
A simple dislocation, with no fracture, is reduced (put back in place) and is usually stable afterward. A complex dislocation involves fractures and is more likely to be unstable, the most severe pattern is the 'terrible triad,' a dislocation with radial head and coronoid fractures, which almost always needs surgery.
Why early motion matters
Scar tissue forms quickly in the elbow, and the longer it is held still, the more it stiffens. Once the joint is stable, supervised motion in the first weeks is the single best protection against a permanently stiff elbow.
After a dislocation is reduced, Dr. Lee tests the elbow's stability and uses imaging to look for fractures. A stable, simple dislocation is treated without surgery, with a brief period of protection followed by early guided motion.
When the elbow is unstable or fractures are present, surgery restores the bony and ligament anatomy so motion can begin safely. Complex elbow trauma, including the terrible triad, is the kind of injury Dr. Lee is referred from outside hospitals.
Non-surgical treatment
A simple, stable dislocation is reduced and protected briefly in a splint, then moved early under guidance, and protected with a hinged brace. X-rays confirm the joint stays located as motion begins.
Surgical treatment
Unstable dislocations and those with fractures are treated surgically to repair or replace the radial head, fix the coronoid, and repair the torn ligaments, so the elbow is stable enough to move early. The goal is a stable joint that does not have to be immobilized into stiffness.
Recovery timeline
Recovery is built around protecting stability while starting motion early:
- Weeks 0 to 2Splint or hinged brace. Begin guided motion within a safe arc once the joint is confirmed stable. Hand, wrist, and shoulder motion encouraged.
- Weeks 2 to 6Progressive range of motion in therapy, often in a hinged brace. Avoid forces that stress the healing ligaments.
- Weeks 6 to 12Strengthening and return to activity as motion and stability allow. Some stiffness is normal and continues to improve.
What patients commonly misunderstand
Two points that matter most:
- Stiffness, not re-dislocation, is the usual problem. Once a simple elbow dislocation is reduced and stable, the main risk is loss of motion from prolonged immobilization, which is why early guided motion is emphasized.
- A fracture changes the plan. A dislocation with fractures is a different injury than a simple one. Imaging matters, because a missed coronoid or radial head fracture can lead to a chronically unstable elbow.
