Distal Clavicle Excision Recovery
Distal Clavicle Excision
What the operation does
The acromioclavicular joint is the small joint at the top of the shoulder where the collarbone meets the point of the shoulder blade. Where it is worn or painful, about a centimetre of the end of the collarbone is removed, leaving a gap so the two bones no longer grind against each other. The joint is not replaced or rebuilt — it is taken out of contact.
Why removing bone relieves pain
The pain comes from two worn surfaces pressing and rubbing every time the arm crosses the body or reaches overhead. Remove the contact and you remove the source. The gap fills with scar tissue, and the ligaments above and below the joint hold the collarbone in place, so nothing collapses.
What it usually treats
Two things. Wear and arthritis of that small joint, which is common with age and often shows on scans in people with no symptoms at all. And distal clavicle osteolysis — sometimes called weightlifter's shoulder — where the end of the collarbone softens and erodes under repeated heavy loading, typically from bench pressing and dips. The operation is the same; the cause is not.
Nothing is reconstructed, so nothing is protected
Worth being clear about, particularly if you have heard about AC joint reconstruction, which is a very different operation on the same joint. There the ligaments holding the collarbone down have been rebuilt and are protected in a sling for six weeks. Here nothing is healing under tension. The sling is for comfort for a few days, movement starts immediately, and the recovery runs in weeks.
Stiffness is the thing to avoid
Because there is nothing to protect, what goes wrong after this operation is a shoulder rested into stiffness. Moving in every direction from the first days is the right instinct, and the soreness that comes with it is expected rather than a warning.
How much bone is taken
There is a balance being struck. Too little and the surfaces still touch at the extremes of movement, so the pain persists. Too much and the ligaments that steady the collarbone can be disturbed, leaving the bone end unstable and sore in a different way. Around a centimetre is typical, and your surgeon judged it against your anatomy.
Whether it was done through keyhole or open
Both are used and the recovery is broadly the same. A keyhole approach leaves smaller punctures and is often chosen when other work is being done inside the shoulder at the same time. An open approach uses a short incision directly over the joint. The bone removed and the timeline are much the same either way.
It is often done alongside something else
Very common — this joint is frequently dealt with while a subacromial decompression or a rotator cuff repair is being done. Where a cuff repair was part of your operation, that is by far the more restrictive and takes over the timetable: a sling for around six weeks and no lifting the arm under its own power. It is worth being certain which operation you had.
Bench press, dips and overhead pressing
The movements that most load this joint, and the ones that caused the problem in the first place for many people. They come back late — commonly around three months — and building up gradually rather than returning to previous weights matters. Some people find a slightly narrower grip or a shallower range more comfortable long term.
Pain relief timeline
Local soreness over the joint settles over two to four weeks. The deeper relief people are looking for usually arrives over one to three months as the tissues quieten. Tenderness on pressing directly over the spot can persist longer and is not unusual.
If pain persists
The commonest reasons are that not enough bone was removed, that the pain was coming from elsewhere in the shoulder as well, or that the joint was never the main source. Where several problems coexist in a shoulder — and they often do — separating what improved from what did not is the useful conversation at your review.
The scar and the bump
An open approach leaves a short scar on the top of the shoulder, in a place clothing and bag straps cross, and it can be sensitive for some months. Some people can feel the end of the collarbone more prominently afterwards, which is expected rather than a sign anything has shifted.
Driving and work
Driving generally waits until you can control the wheel with both hands comfortably — commonly around one to two weeks for an isolated excision. Desk-based work is often possible within a few days. Work involving overhead reaching or lifting commonly returns within four to eight weeks.
How the first months usually unfold
The first two weeks are about comfort and moving the shoulder freely in every direction. Two to six weeks brings full movement and light strengthening. Six to twelve weeks is where strength rebuilds and most people return to their usual activity. Three to six months brings heavy pressing and overhead loading back gradually. Beyond that the work is keeping the shoulder strong rather than recovering.
Staying in touch with your care team
What else was found and treated in your shoulder changes this recovery more than the excision itself does. Your surgeon knows what they saw. If something about your recovery is worrying you or does not match what is described here — particularly a shoulder losing movement rather than gaining it — contact your care team.
