Reverse HAGL: a possible complication of a tight anterior gleno-humeral stabilization.
Recently the posterior humeral avulsion of the glenohumeral capsule (Reverse HAGL or RHAGL) has been reported in the orthopaedic literature as another possible cause of posterior traumatic shoulder instability. In the present paper we describe three patients in whom a RHAGL was probably a consequence of a tight open anterior shoulder stabilisation. The main complaint of these patients was a stiff shoulder after an open anterior stabilisation. A progressive and worsening discomfort was reported by patients in spite of an accurate rehabilitation program. At persistence of symptoms arthroscopy was performed with evidence of RHAGL that was repaired in association with an anterior release. Clinical and functional improvement was observed but the final outcome seems to be related to range of motion recovery and not only to the posterior repair.
