The Joint That Punishes Rest Harder Than Any Other in the Body
After the shoulder, the elbow is the most commonly dislocated joint in adults. Usually it happens from a fall onto an outstretched hand, usually the forearm bones popping backwards off the end of the upper arm.
It goes back in, often the same day, under sedation. The X-ray afterwards looks fine. Everyone immediately relaxes.
But us hand therapists dont – because…the part that decides your next year, and it is almost never explained properly on the day:
The elbow stiffens faster and harder than any other joint in the body. Left in a sling to rest, it will start locking down within two weeks. And a stiff elbow is one of the most stubborn problems in the whole of upper limb rehab.
What’s actually happening in there
The elbow is three joints sharing one capsule, wrapped tight, with very little spare room. That’s what makes it stable and precise.
When it dislocates, the capsule and the ligaments either side get torn, and the joint bleeds into that closed space.
Blood inside a joint capsule is not neutral.
It’s an irritant, and it’s the raw material for scar.
- The capsule thickens,
- the fibres shorten, and
- the muscles crossing the front of the joint tighten up protectively at the same time.
Add the natural resting posture of a sore arm…held bent, held close…and you have a joint being scarred into a bent position by a body that thinks it’s helping.
Some elbows go further and lay down actual bone in the soft tissue around the joint. That’s more common after high-energy injuries and after elbows that were immobilized too long or stretched too aggressively.
Simple versus complex, and why it matters
A simple dislocation is soft tissue only. The bones are intact, the joint is stable once reduced, and the plan is early movement.
A complex dislocation comes with fractures…the radial head, the coronoid, or both. Those are less stable, often need surgery, and follow a different protocol entirely.
You need to know which one you had, and it’s a fair question to ask directly. The answer changes everything about how soon and how freely you should be moving.
Worth checking on the day and in the following week: numbness or tingling in the ring and little fingers, which points at the ulnar nerve running right behind the inner bony point; a cold or dusky hand; and any sense of the joint shifting or clunking, which suggests it hasn’t stayed properly located.
The two-week window
For a simple dislocation, the current standard is early motion. In DAYS, not weeks. A sling for comfort in the first few days, used less and less, and movement started within roughly the first week.
Anything past two to three weeks of immobilisation and the stiffness curve starts running away from you.
Every extra week in a sling costs more range loss and stiffness than it buys comfort.
This is where a lot of elbows are quietly lost.
Not to the injury…to the gap. Discharged from A&E with a sling, no therapy booked, no follow-up for six weeks, and by the time anyone measures the joint it has already set.
If you take one thing from this article: ask, on the day, who is doing your rehab and when it starts. If the answer is vague, that’s the gap forming.
What treatment actually looks like
Movement, early, within whatever safe arc your surgeon has specified. Bending is usually easy and comes back first. Straightening is the one that fights you, and straightening is what you’ll be working on for months.
Same principle as any stiff joint: time (duration) and frequency at end range beats hard force. Long, gentle holds at the limit of straightening, repeated through the day, remodel the capsule. Yanking on it does not, and in this joint specifically, aggressive passive stretching can make things worse rather than better.
(The elbow is the one joint where I’ll actively tell people to be gentler than their instincts. It responds badly to being forced.)
Where range stalls, static progressive or turnbuckle splints deliver the hours the joint needs. Where it stalls completely at six to twelve months despite good rehab, surgical release of the contracture is a genuine option…with the same caveat as everywhere else, that the operation only works if the rehab after it is done properly.
What recovery feels like
- Week 1: swelling, bruising, sling for comfort only. Movement starting within the safe arc. Shoulder, wrist and hand kept fully moving…they stiffen too, and nobody watches them.
- Weeks 2 to 6: the critical stretch. Range should be improving week on week. Range that plateaus here needs escalating, not waiting on.
- Weeks 6 to 12: most of the bending range back, strengthening begins, straightening still lagging.
- Months 3 to 12: the long tail. Straightening keeps improving slowly. Strength and confidence return.
Honest expectation, and it’s worth hearing early: losing the last 10 to 15 degrees of straightening is common after an elbow dislocation, and often permanent. Functionally most people never notice. Aching in cold weather and after heavy days can persist for a year or more. Some ongoing wariness of falling on that arm is normal and fades.
The short version
Find out whether yours was simple or came with a fracture. Get movement started within days, not weeks. Expect bending to return easily and straightening to be the long project.
And treat any stall in range as a reason to escalate immediately. The elbow gives back what you ask for early and almost nothing you ask for late.

This article explains; it doesn’t examine. An elbow that isn’t gaining range week on week needs assessing now, not at the next appointment.
