Combined large Hill–Sachs and bony Bankart lesions treated by Latarjet and partial humeral head resurfacing

Location: http://www.cma.ca/multimedia/staticContent/HTML/N0/l2/cjs/vol-52/issue-3/pdf/pg249.pdf

The bony conformity of the glenoid and humeral head articular surfaces provides some of the stability of the shoulder. Frequently, patients with recurrent dislocations have bony deficits in one or both of these sur- faces. Glenohumeral instability with substantial glenoid defects or engaging Hill–Sachs lesions poses a difficult challenge for...

Multidirectional Glenohumeral Instability eMedicine Orthopedics

Location: http://www.emedicine.com/orthoped/topic521.htm

Multidirectional instability (MDI) is a relatively common, generally bilateral, atraumatic condition affecting shoulder function. MDI is caused by generalized capsular laxity—that is, insufficiency of the static ligament constraints. There is excessive mobility of the glenohumeral joint in all directions, although there may be a predominance of 1 direction, typically anteroinferior...
