I had this surgery with Dr. Kibler. Supposedly my rhomboids were detached and part of my lower trap was reattached. I say supposedly because this cannot be confirmed on MRI due to the location of your rhomboids being so deep and attaching underneat the scapula. Dr. Kibler looks at the movement of your scapula to make this diagnosis. Mine was fanning out to the side when I elevated my arm.

While it corrected the movement of my scapula unfortunately this was just a symptom or damage from an underlying problem that has still not been resolved. It did not help the pain I was having at all.

With that said I do believe this surgery has a good chance to help you if you can tie the detachment to an event like the car accident you mentioned. I would do everything you can to be as sure of the diagnosis as possible. The surgery is not easy as he drills holes in your scapula and threads the muscles back to it. However TOS surgery was more painful (yes I had both).

Dr. Kibler is highly regarded and considered the guru for scapula problems. His physical therapy team is very good as well.

Feel free to send me private message if you want to know more.
