Not sure if this will be helpful, but DH had shoulder surgery. Went in thinking it was just bone spurs (HAH!), but ended up much more complicated including a biceps tendon tear (off the bone), labrum injury and rotator cuff tear. Surgical screws and hardware to secure the biceps tendon initially failed during surgery due to another unanticipated medical problem, so it was a much longer surgery than anticipated. Was sent home same day, which was a big mistake. DH should have been admitted for adequate pain and nausea control, and to remain adequately hydrated.
Not exactly your diagnosis or scenario, but some things you may find helpful:
At home, I had to find
a recliner (purchased locally on New Year’s Eve day, IIRC)
many, many pillows of different sizes and densities
lots of assorted cold packs/soft gel packs/ice
easy on/easy off clothing–pullover tops were impossible
several small blankets to drape or roll as needed
I also found that a real sheepskin “tube” as used for a shipping halter, was helpful for padding the sling strap on opposite neck/shoulder.
Recliner was essential, and the only way DH could sleep for about two months. No amount of propping pillows and bolsters in a normal bed worked to allow any sleep.
The Game Ready would have been a great thing, but was not available where we were at that time. Glad you have that lined up.
Is this for your dominant arm? If so, you may have to improvise how you do things, especially if you are doing self-care. Or start practicing things like brushing teeth etc., with your non-dominant arm. Plan on at least two months of assistance, and maybe you will be able to lead a horse safely by then? Last thing you want to do is wreck the repair!
If you have confidence in your surgeon, and know exactly what needs repair, it hopefully will not be as traumatic as DH’s experience. (Surgeon did not feel he needed a MRI, just a CT. The advanced imaging may have given info to prepare for a more involved procedure. I don’t think it would have revealed the bone density issue.)
I was designated driver for all outings, as DH could not manage it for quite a few weeks. Not just strength and ROM-wise, but any jostling or jarring of his arm was not good. Only after he got the ok from his PT, and was off any pre-PT pain meds, did he attempt to drive on his own.
Long-term outcome: good to very good. DH was playing golf within 7-8 months. Longer than expected because the case was more involved than expected.
Jingles for an easy procedure and recovery!
