Structure
The subtendinous bursa of subscapularis is a closed sac of synovial fluid which sits on the lateral aspect of the scapula, near the scapular neck.
The subtendinous bursa of subscapularis muscle communicates with the synovial cavity of the glenohumeral joint via an opening in the fibrous layer of the capsule. This opening is situated on the anterior aspect of the joint just inferior to the coracoid process of the scapula (Moore et al., 2013). It corresponds to the region between the superior and middle glenohumeral ligaments (Standring, 2016).
Function
The subtendinous bursa of subscapularis muscle permits friction-free movement between the tendon of subscapularis muscle and the coracoid process, and the scapular neck.
