Overview
what it is and why it mattersThe elbow is the second most commonly dislocated large joint (after the shoulder). The most common version is a "simple" dislocation: a fall onto an outstretched hand pushes the forearm bones backward out of the elbow joint. A "complex" dislocation also breaks bones — the most unstable combination is the terrible triad: a dislocation plus a coronoid fracture plus a radial head fracture. Every elbow dislocation tears the ligaments and capsule that hold the joint together.
Symptoms
what you may noticeThe moment your elbow dislocates you'll feel intense pain and be completely unable to bend or straighten the joint. The bony point at the back of your elbow (the olecranon) juts backward, creating a visible step-off that's obvious through the skin. Swelling and bruising spread quickly around both sides of the joint.
Many patients notice tingling or numbness in the ring and small fingers — that's the ulnar nerve being stretched as the joint displaces. In more severe injuries (a "complex" dislocation with fractures), you may feel grinding when anyone touches the elbow, and the joint may feel as though it wants to slip back out even after reduction.
Diagnosis
exam first, imaging secondSevere elbow pain, a visible deformity at the back of the elbow, and you can't move the joint. Your surgeon will carefully check the nerves and blood vessels around the elbow before doing anything else — particularly the ulnar nerve and the small motor nerve to the thumb. Front and side X-rays confirm the dislocation and look for fractures. After the elbow is reduced (put back into place), a CT scan looks for any associated bone injuries.
Treatment Path
how care progresses at OSI1
Closed reduction
The elbow is put back into place promptly under sedation — gentle pulling on the forearm while bending the elbow walks the joint back into position. After reduction, your surgeon checks how stable it is across a full range of motion.
2
Hinged elbow brace
For dislocations that are stable after being put back — a hinged brace allows early controlled motion of the elbow while protecting the healing ligaments. Starting motion early is critical: the elbow stiffens up faster than almost any other joint.
Surgical Options at OSI
if non-operative care isn't enoughSurgery is needed when the elbow won't go back into place by manipulation, when it keeps slipping out after reduction, or when the dislocation came with bone fractures (especially a terrible triad) — those need ligament repair and fracture fixation to give the joint enough stability to start moving early.
