The Persian Prybar
•••••••••••••••••
Dustin Akbari, @persian.fury, one of the most exciting grapplers at the recent East coast ADCC trials had no shortage of highlight real matches. One in particular where Akbari used a creative shoulder lock to submit his opponent that @flograppling writer @hywelteague coined the term “Persian Prybar”.
.
Anatomically what is happening with this joint lock?
This joint lock differs from a Kimura or Americana because it primarily is creating a shear force to anterior translate the glenohumeral joint in the glenoid fossa. This motion is common for anterior shoulder dislocations.
.
The rotator cuff muscles help to stabilize the humeral head in the glenoid fossa with the subscapularis being the primary dynamic constraint that may resist this motion. The static structures that oppose this motion are anterior band of the inferior glenohumeral ligament, axillary pouch and the middle glenohumeral joint ligament. A forceful anterior translation may also fray or tear the glenoid labrum. Glenohumeral capsule laxity can also occur from repeated stretching of these structures, such as years of late tapping to this shoulder lock.
