A day in theatre
Dr Kenneth Cutbush hosted the Sydney shoulder surgeon Doron Sher for a day in theatre at Brisbane Private Hospital.
Why surgeons visit each other's theatres
Visits of this kind are a standard part of how surgical technique travels. A paper or a conference video can set out the principle of an operation, but the detail that decides whether it works in a particular pair of hands sits in the ordinary business of a working day: how the patient is positioned, which portals are used and in what order, how a graft is prepared and passed, what is done when the anatomy is not as expected. Watching a full list, and discussing the decisions as they are being made, conveys that in a way reading does not. The traffic runs in both directions, since the visiting surgeon brings their own practice into the conversation.
What an irreparable rotator cuff tear means
The rotator cuff is a group of four muscles whose tendons wrap over the top and sides of the ball of the shoulder. They hold the ball centred in its shallow socket and allow the much larger deltoid muscle to lift the arm without the joint riding upwards. When a cuff tendon tears, that balance is disturbed, and lifting the arm becomes weak, painful or both.
A tear is described as irreparable when the tendon can no longer be brought back to its attachment on the bone and held there, usually because it has pulled away and scarred over a long period, or because the muscle itself has wasted. Stitching it back is then not an option, which is the problem that reconstruction with a graft is intended to address. Individual results vary.
Superior capsular reconstruction
The discussion centred on superior capsular reconstruction (SCR), which Dr Cutbush uses in two situations: where a rotator cuff tear is irreparable, and to reinforce a massive tear that is at risk of re-rupture after repair.
In both cases the principle is the same, which is to restore a restraint across the top of the joint with a graft, so that the shoulder is not relying on tendon that is absent or compromised. Individual results vary, and which approach suits a particular shoulder depends on what remains of the cuff.
