TRAPEZIUS

 


 

Trapezius  2 x 7.5-10 u Max 50 u Botox;  2 x 30-40 max 200 u Dysport


The trapezius is superficial and is generally easily palpated at the base of the neck. The muscle is usually considered to have three functional parts: upper, middle, and lower.  The trapezius’ lateral attachments are the same as the proximal attachments of the deltoid: the lateral clavicle, the acromion process, and the spine of the scapula.

The trapezius has a variable role in causing abnormal head posture, but, at the least, the muscle often seems to cause pain, which is effectively treated with botulinum toxin.

Recommended to inject trapezius at the base of the neck with one or two injections.

Relations: directly deep to the trapezius in the neck are the semispinalis capitis, the splenius capitis, and the levator scapulae. 
Directly anterior to the anterior border of the trapezius are the splenius capitis, the levator scapulae, and the scalenes (in the posterior triangle of the neck)

The video shows positioning of the ultrasound probe and of the EMG needle. The muscle belly is visible on the background screen.
