For those with past A/C Separations - chronic instability increasing further injury

I am just over 4 months out from a high grade 2, possible grade 3 a/c separation from a mountain bike spill. Imaging showed a 14mm gap between the Acromion and Clavicle, however when palpated it didn’t feel like a complete tear of both ligaments so Docs said to skip surgery. Things have been going really well, back in the gym able to do most everything with only slight pain. For weight training days, clean and presses are fine, dumbbell bench press would cause pain but it was easily dealt with. With that said I was noticing slight instability in my injured shoulder (right). If I were to push or pull on it a certain way I would feel some movement as well as a noticeable creaking/clicking (crepitus like, but not quite). Even as simple as being in bed and moving my shoulder around, the movement was very obvious. From what I understand, this is normal until the a/c joint “files” down.

The other day I unknowingly re-injured the same shoulder. This time it’s directly under the scapula, as if a rotator cuff injury (Infraspinatus perhaps). Don’t really remember what I might have done which is unfortunate, I just woke up one day with the pain. I jumped to a rotator cuff injury based on what I know, but none of the upper extremity special tests were positive ( Supraspinatus, Infra, Teres minor, Subscap lift off & impingement). So thinking about it, perhaps it is more related to the rhomboid… I’m at about 8 days post injury with no improvement. I can swim, however there is enough pain after that it’s probably not a good idea. If I were to pick up a 30 pound dumbbell (in the OPPOSITE hand) it causes a sharp, pinpointed intense pain (about 6/10) that isn’t quite bad enough to make me drop the weight, but I must immediately set it down. I can ride the bike, but if I move a certain way in the tuck I will uncontrollably grunt to the pain.

I’m starting to wonder if my shoulder instability post a/c separation was in fact NOT normal. And this chronic instability is now leaving me more prone to other shoulder injuries (like what I just got). For those of you with a/c separations in the past, how is the shoulder now? Are you experiencing an increase in other shoulder related problems?

I had a complete, 100% separation of my shoulder on my 21st birthday that was not repaired. I am now 42 years old.

It took about a year for my body to adjust to my new anatomy. My back hurt. My neck hurt. My shoulders hurt. It was pretty miserable for awhile.

For the first couple years, every once in awhile, I would pinch a little bit of soft tissue between the end of the clavicle and the coracoid and that would be a moment of sharp pain. That hasn’t happened in years.

I’m not sure what you mean by instability. My scapula/shoulder apparatus has no bony attachment to my body any longer. That is probably the difinition of instability. I have never had any issues related to this. I sometimes wonder what it will be like when I am 92. Will my shoulder slide down to my waist? I guess this is a good reason to keep fit/maintain my muscle mass.

I have had no additional shoulder issues. I can do everything with my AC deficient shoulder that I do with my normal shoulder. Pushups, pullups, dips, swimming, etc. I have noticed that when I am in aero that my ‘injured’ shoulder tucks in very narrow and makes me way more aerodynamic. If I could do this with both of my shoulders I would present a much smaller frontal profile. This benefit is not enough to make me go out and separate my good shoulder… but I am always looking for positives :slight_smile:

I stopped road racing due to same injury but maybe not as severe as yours. Had A-C separation. Started tri training because the competitor in me wouldn’t let me stop competing. Swimming has helped me rehab my shoulder to NEARLY pain free periods. Since I stare down at my laptop most of my work day, I feel the scapular muscles of the traumad shoulder tense up and need to have massaged often but my A-C area is pain free.

Good luck in your recovery…
