2. Branch of radial nerve to the
long head of triceps
Anterior br. of axillary n.
(to ant.& middle deltoid m ±post
deltoid.)
J Hand Surg 2003;28A:628–632

3. Nerve. to long head of triceps
Anterior. br. of axillary n.
Posterior approach J Hand Surg 2003;28A:628–632

4.  Distal spinal accessory n. Suprascapular n.
 N. to long head of triceps Ant. br. axillary n.
Posterior
Approach
J Hand Surg 2003;28A:633–638

5.  All cases gained M4 or better
 Average shoulder abduction 124°
 No functional deficit of the triceps
 No muscle re-education needed
J Hand Surg 2003;28A:633–638

7.  The nerve to the long head of the triceps
 Expendable
 A pure motor nerve
 Constant origination point
 Proximity to the axillary nerve
 Similar size to the axillary nerve
 No specific motor re-education required
Clin Anat. 2013 ;26(3):386-91

8. Transfer to The Anterior Branch of
The Axillary Nerve
 Avoid wasteful regeneration of axons into
the teres minor and the superior lateral
cutaneous nerve

10. Selective transfer to Ant
branch of Axillary nerve
