Which of the following nerves has the greatest risk for direct injury at the stated locations during arthroscopic lysis of adhesions for adhesive capsulitis?
    • Musculocutaneous nerve lateral to the coracoid when establishing an anterior portal
      • The axillary nerve rather than the musculocutaneous nerve is at greatest risk

 

    • Axillary nerve in the posterior deltoid when establishing a posterior portal
      • The axillary nerve is at greatest risk due to its proximity to the glenoid when releasing the inferior glenohumeral ligaments, not when establishing a portal

 

    • Axillary nerve at the inferior border of the glenoid when releasing inferior glenohumeral ligaments
      • The axillary nerve is at greatest risk due to its proximity to the glenoid during the release of the glenohumeral ligaments

 

    • Suprascapular nerve when performing debridement of the rotator interval tissue
      • The axillary nerve rather than the suprascapular nerve is at greatest risk
