Medial Border Of The Scapula, Posterior View

Description

Scapula anatomy is centered here on the medial (vertebral) border, the long vertical margin of the shoulder blade running between the superior angle superiorly and the inferior angle inferiorly. From a posterior perspective, this border lies medial to the scapular spine and the infraspinous fossa, and it parallels the thoracic vertebral column across the posterior thorax. The medial border forms a sharp transition between the costal surface (anterior, not visible) and the posterior surface where muscle attachments cluster along the margin. Clinically, the vertebral border is the palpated reference line when assessing scapular positioning and dyskinesis, because medial border prominence is a common bedside cue in serratus anterior palsy (long thoracic nerve injury) and in trapezius weakness (spinal accessory nerve injury). Rhomboid major and minor insert along this margin, and the dorsal scapular nerve courses deep to these muscles, so the border is a practical landmark when discussing posterior shoulder pain patterns and surgical or injection approaches near the medial scapula. Surface anatomy matters here. The fixed posterior presentation also supports teaching the relationship of the medial border to the superior and inferior angles, which helps learners orient fractures and traction apophysitis patterns around the scapular perimeter. Use this illustration in gross anatomy and kinesiology teaching to anchor scapulothoracic mechanics, protraction versus retraction, and muscle maps for rhomboids, levator scapulae at the superior angle region, and lower trapezius fibers approaching the medial border near the spine of the scapula. It also fits orthopedic and sports medicine materials covering winged scapula evaluation, posterior shoulder examination landmarks, and operative notes that reference the vertebral border and angles for incision planning and fracture description.
