A, −B, −C demonstrate sub/trapezius sub-acromial passage of the hamstring sheet in currently reported technique of middle trapezius tendon transfer in the right shoulder. A, a long straight artery clamp (marked in yellow circle) passed through McKenzie approach under the acromion to the scapular wound to establish a sub-trapezius/sub-acromial corridor; B, sub-trapezius/sub-acromial shuttling of the hamstring sheet aided by the passed long straight artery clamp (marked in yellow circle); or alternatively by; C, an anterior cruciate ligament guide pen (marked by white arrows); the latter is valid for both open and arthroscopic-assisted modalities of currently reported technique; AMG, anterior mid-glenoid portal; HS, Hamstring sheet; LS, lateral sub-acromial portal
