Spine of scapula

The Human Scapula Bone

The spine of scapula is a structural feature on the scapula bone (also known as the shoulder blade or shoulder bone).

The spine of the scapula bone is a prominent projection (alternatively described as a "plate" of bone) that extends across the top of the dorsal surface of the scapula, as shown in the diagram below.

The spine of the scapula separates the supraspinous fossa (above the spine of scapula) from the infraspinous fossa (below the spine of scapula).

The spine of the scapula itself has two surfaces, the upper, or 'superior' surface and the lower or 'inferior' surface, and three borders - anterior, posterior and crest. The superior surface of the spine of scapula is concave and leads to the supraspinous fossa.

For more about this and related topics see the links to other features on the scapula bone listed on the left and the pages about the scapula bone and about bone markings and features on bones.
