Abstract

|
Delaminated rotator cuff tear pertains to the horizontal split of the tendon substance. As reported previously, the presence of a delami-nated tear and incidence of delaminated rotator cuff tear ranges from 38% to 92%. The different strain intensities applied across the rotator cuff tendon, and the shear stress between the bursal and articular layers seem to play a role in its pathogenesis. In a delaminated rotator cuff tear, the degree and direction of retraction between two layers differ, with accompanying intrasubstance cleavage. A surgeon therefore needs to consider and carefully evaluate the tear characteristics when repairing delaminated rotator cuff tear. Delaminated ro-tator cuff tear is considered to be a poor prognostic factor after rotator cuff repair, but numerous surgical repair techniques have been in-troduced and applied to resolve this problem. Recent literature has reported good clinical outcomes after delaminated rotator cuff repair.
