Burkhart's 1994 landmark paper challenges the 'cover the hole' dogma for rotator cuff surgery. It asks not how big the tear is, but whether the shoulder remains biomechanically functional. The paper introduces the rotator cable/crescent suspension bridge model and five criteria defining a 'functional cuff tear' to guide the decision between repair, debridement, and partial repair.
For decades, massive rotator cuff tears were managed by the principle Codman established: cover the hole. Techniques including fascial grafts, freeze-dried allografts, and tendon transpositions followed this logic regardless of whether they respected shoulder mechanics.
This paper reframes the operative question entirely. When you see a massive tear, ask: are the force couples intact? Is the rotator cable intact? Can the patient externally rotate and does the lift-off test? If yes to all three, that is a functional tear — debridement plus decompression can yield 90% good/excellent results without open reconstruction.
When force couples are lost (weak or absent external rotation, positive lift-off), that is a dysfunctional tear. In a high-demand patient, partial repair targeting the inferior infraspinatus to restore the cable and transverse force couple is the move. Not complex tendon transfers that violate the mechanics you are trying to restore.
The clinical pearl most worth carrying: a residual 1×3 cm hole after partial repair is acceptable. Function follows force couple restoration, not anatomic coverage.
