The authors point out that prior authors suggested coracoid morphology may be related to subscapularis pathology.
This illustration proposes a "roller wringer" phenomenon
This MRI is thought to show a decreased coracohumeral space and complete tear of the subscapularis tendon.
These authors examined MRIs of 201 patients 45 years or older who underwent shoulder arthroscopy for any indication, measuring the coracohumeral distance (CHD), lateral extent (LE), and caudal extent (CE) of the coracoid process. Patients’ subscapularis condition was assessed via operative reports; stratified according to Lafosse grade criteria.
112 patients had no evidence of subscapularis injury, whereas Lafosse grade I injuries were identified in 52 patients; grade II, in 19; and grades III-V, in 18.
The CHD, LE, and CE were not correlated with the degree of subscapularis injury
They concluded that coracoplasty may not be necessary prophylactically or as part of subscapularis repair.
