Biomechanical background of the currently reported technique in left shoulder; (1) restoration of humeral head sphericity; and as a sequel, congruent gleno-humeral articular arc is increased and engagement is negated; (2) capsulorrhaphy of the lax, redundant and stretched-out posterior gleno-humeral capsule is to help keep the humeral head centred over the glenoid; FG, Fibular graft pieces, G, Glenoid; GT; Greater tuberosity; LT, Lesser tuberosity; PC, Posterior gleno-humeral capsule; SSC, Subscapularis muscle/tendon
