Description: Ans. (a) Axillary nerveRef.: Maheshwari 9th ed. / 91* The shoulder is the most frequently dislocated joint. It moves almost without restriction but pays the price of stability. The shoulders integrity is maintained by the gleno-humeral joint capsule, the cartilaginous glenoid labrum (which extends the shallow glenoid fossa), and muscles of the rotator cuff.* Anterior dislocations occur in as many as 98% of cases. Anterior displacement of the humeral head is the most common dislocation seen by emergency physicians.Shoulders Pathology and Nerve Involved* Ant.
