Levator Scapulae at Scapular Insertion

musculus levator scapulae (insertio)

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.

Nerve: Dorsal scapular nerve (C3, C4, C5) and direct… Blood Supply: Transverse cervical artery Region: Shoulder

Anatomical Data

Origin, Insertion & Supply

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

Biomechanics

Function & Actions

Actions	Elevates and medially rotates the scapula (depresses the glenoid); Lateral flexes the neck when the scapula is fixed

Clinical Relevance

Clinical Notes

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.

Palpation

Palpated at the superior angle of the scapula during resisted ipsilateral cervical lateral flexion.

Pathology

Common Injuries & Conditions

Levator Scapulae Syndrome

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.
