spine of scap·u·la

[TA]
the prominent triangular ridge on the dorsal aspect of the scapula, providing attachment for the trapezius and deltoid muscles and separating the supraspinous and infraspinous fossae; the acromion is a lateral extension from the spine.

The deltoid muscle was mobilised from the distal third of clavicle, acromion, and the lateral third of the spine of the scapula.
1) Spino-scapular distance: (a) at the spine of the scapula bilaterally; (b) at the inferior angle of the scapula bilaterally.
2) Level of the Scapula: (a) at the spine of the scapula bilaterally; (b) at the inferior angle of the scapula bilaterally.
In this process two inclinometers were involved: one of them was set on the spine of the scapula and the other one placed on the posterior face of the humerus, touching the olecranon.
The difference stemmed from the use of two inclinometers and from the difficulty of positioning one of them on the spine of the scapula, which is not flat.
If the root of the spine of the scapula is higher than T3, the shoulder is elevated; if the root of the spine of the scapula is lower than T3, the shoulder is depressed.
Middle trapezius electrodes were placed 2 cm apart and parallel to the muscle fibers between the thoracic vertebrae and the medial border of the spine of the scapula.
After injecting intradermally into the painful (Ah shi) points on the scapulae, especially under the spine of the scapula, the whole scapula may have many more painful points, 10 or 15 or more each side, and need to be injected.
As this study focused mainly on the spinal level measured from the inferior scapular angle, I would further suggest to practitioners to measure other bony landmarks, on the radiograph such as the spine of the scapula for the approximate level of T3, the iliac crest levels for approximately L4.
We actually have considered assessing which spinal level corresponds to the root of the spine of the scapula on a radiograph and are exploring the feasibility of such a study.
The thenar eminence of the right hand is placed along the spine of the scapula with the thumb straight and pointing laterally.
The patient stands with the spine of the scapula perpendicular to the cassette.
