Rhomboid Minor Muscle, Posterior View

Description

Posterior trunk anatomy is presented with the scapular girdle centered on the rhomboid minor, a small quadrangular muscle spanning from the nuchal ligament and spinous processes of C7 to T1 to the medial border of the scapula at the level of the scapular spine. It lies inferior to the levator scapulae and superior to the rhomboid major, with its fibers running inferolaterally from the vertebral column toward the scapula. Superficially, the trapezius blankets the region from the midline to the acromion and scapular spine, and the deltoid caps the lateral shoulder while the latissimus dorsi appears more inferior and lateral. Clinically, this posterior view helps clarify why scapular retraction and downward rotation depend on coordinated action between the rhomboid minor, rhomboid major, and middle trapezius, and why imbalance often presents as medial scapular border prominence and altered scapulothoracic rhythm. Dorsal scapular nerve (C5) irritation or injury can weaken the rhomboids and levator scapulae, producing fatigue with sustained posture and pain along the medial scapular border that can mimic cervical radiculopathy. A small muscle. A frequent pain generator. The layering with trapezius also mirrors the surgical reality: reaching the rhomboids for dorsal scapular nerve decompression, scapular fixation procedures, or posterior approaches to the upper thoracic spine requires controlled trapezius elevation along the medial scapular spine. Use this illustration in gross anatomy and kinesiology teaching to compare the rhomboid minor and major, to map attachments to the vertebral midline and medial scapular border, and to explain scapular dyskinesis in physical therapy and sports medicine materials. It also suits orthopedic and spine publications that need a clear posterior surface anatomy reference before deeper dissection planes. Anatomical accuracy verified by SciePro's Medical Advisory Board.
