Although levator scapulae originates in the neck, its distal insertion at the superior angle of the scapula is a shoulder-region structure of clinical importance. The insertion point is the site of pain in levator scapulae syndrome and is accessible for dry needling and injection in shoulder-level practice.
| Origin | Transverse processes of C1-C4 (as Neck-level muscle) |
|---|---|
| Insertion | Superior angle of the scapula and adjacent medial scapular border |
| Nerve Supply | Dorsal scapular nerve (C3, C4, C5) and direct branches from C3-C4 anterior rami |
| Blood Supply | Transverse cervical artery |
| Actions | Elevates and medially rotates the scapula (depresses the glenoid); Lateral flexes the neck when the scapula is fixed |

Levator scapulae insertion tenderness at the superior scapular angle is the defining feature of levator scapulae syndrome, producing a characteristic pain pattern from the neck to the superior scapular angle. The insertion is treated with trigger point dry needling, massage, and stretching. Botulinum toxin injection at the scapular insertion addresses refractory cases. It is also the attachment released in superior angle snapping scapula surgery.
Palpated at the superior angle of the scapula during resisted ipsilateral cervical lateral flexion.
Myofascial pain at the levator scapulae scapular insertion producing neck-to-superior-scapular-angle pain, reproduced by compression at the superior scapular angle, managed by dry needling and cervicoscapular stretching.
