Bennett lesion of the shoulder

A.Prof Frank Gaillard et al.

A Bennett lesion (of the shoulder) refers to a mineralisation of the posterior band of the inferior glenohumeral ligament . 

More prevalent in overhead throwing athletes.

Patients may have pain during the cocking and follow-through phases of throwing. There may be tenderness of the posterior glenoid on palpation.

It is thought to be due to a traction injury of the posterior band of the inferior glenohumeral ligament during the deceleration phase of throwing.

Associations

It is associated with posterior labral tear, posterior undersurface rotator cuff tear, and posterior subluxation of the humeral head.

Plain radiograph and CT

It is best seen on CT or axillary view x-ray of the shoulder as a curvi-linear extra-articular calcification along the posteroinferior rim of the osseous glenoid near the attachment of the posterior band of the inferior glenohumeral ligament .
