Doc, do they not rebuild the attackment in BCgroove during slap-surgery?
I suspect one important point to remember about the G-H joint is that while the glenoid capsule, which is formed by the rotator cuff muscles "wraping around" the humerus provides MOBILITY, the labrum ensures STABILITY.
This is an extremely important function since only 20-30% of the humerus is in contact with BONE, something must keep it there and that is the function of the labrum.
Thus absent a fully functional labrum, which tightly pulls the humerus over the bony glenoid, subluxation can become an everyday occurrence to varying degrees, depending upon the SLAP GRADE.
Indeed SLAP tears allow for even greater translation of the humerus superiorly worsening impingement remarkably which is why the SLAP and the A-H outlet MUST BE repaired simultaneously for an optimal outcome. And conversely for the same reason, the BT transfer may be delayed in NON-THROWERS.
'Tthrowers" are somewhat different because they typically develop a SLAP tear by literally pulling the BT off the labrum. This is one instance in which both surgeries, BT transfer and a SLAP repair, may be performed simultaneously. However since the forcers generated by the biceps itself in throwers is less than 5% many simply don't miss the diminished strength especially after "retraining" is completed.
