During an arthroscopic inferior capsular release for severe adhesive capsulitis, the surgeon must be particularly careful to avoid injury to which nerve located directly inferior to the glenohumeral joint?

Explanation:
The axillary nerve runs dangerously close to the inferior capsule of the glenohumeral joint as it passes through the quadrangular space. During an inferior capsular release (cutting the capsule at the 6 o'clock position), the nerve is at significant risk, sometimes lying just millimeters from the capsule. Careful dissection and avoiding the use of thermal energy devices directly on the inferior capsule are advised. Reference: Miller's Review of Orthopaedics, 8th Edition.
