What is shoulder replacement surgery?
Your shoulder is a ball-and-socket joint held together and driven by the four muscles of the rotator cuff. When the cartilage wears out, or when the cuff gives out, the joint stops working, and no amount of waiting brings it back.
In an anatomic total shoulder replacement, the worn ball and socket are replaced with implants that mirror your natural anatomy. It is an excellent operation, and it depends on one thing: your rotator cuff must still be intact and working, because the cuff is what drives the new joint.
In a reverse total shoulder replacement, the anatomy is deliberately flipped. The ball is fixed to the shoulder blade and the socket to the arm, so the powerful deltoid muscle can lift the arm instead of the cuff. It is the answer when the rotator cuff is torn beyond repair, when arthritis has developed alongside cuff failure, or after a complex fracture.
The wait nobody counts. Canada sets a national wait-time benchmark for hip and knee replacement, and reports on it publicly. Shoulder replacement is not on that list. It is not a benchmarked priority procedure, which means shoulder patients often wait behind the joints governments are measured on, largely uncounted. Orthopedic surgery already carries one of the longest waits in Canadian medicine.
