A, −B demonstrate direction of force vector of transferred medial portion of the middle trapezius of the current technique in the right shoulder. Compared with that of Moroder et al. of transfer of acromial/lateral portion of the middle trapezius insertion, force vector in currently reported technique is more-collinear with that of supraspinatus muscle; A, acromion; C, coracoid; Cl, clavicle; G, glenoid, HH, humeral head; HS, hamstring sheet; LT, lower trapezius; MT, middle trapezius; MT-L, middle trapezius (lateral insertion); MT-M, middle trapezius (medial insertion); SS, scapular spine; SSP, supraspinatus muscle (atrophied)
