Cadaver specimen trial of screw application (Right shoulder specimen). (a) Entry point (EP), being the mean of all CT measurements, marked on the posterior scapular neck (red dot) 10 mm from glenoid rim (blue line) through a posterior surgical (Brodsky) approach between infraspinatous (IS) and teres minor (TM) muscles. (b) Ideal drill bit trajectory (blue line) in coronal plane referencing the para-coronal angle from scapular spine (red line) while the sagittal plane control is done under fluoroscopic guidance.
