Calssfication of Shoulder Instability

Thomas and Masten in 1989

TUBS - traumatic unidirectional Bankart lesion treated with surgery


AMBRI - atraumatic multidirectional bilateral

                bilateral treated with rehabilitation

              responds with inferior capsular shift and closure of rotator cuff interval



Stanmore classification

Type I - true TUBS , structural

Type II- true AMBRI , strucutral

Type III - muscular patterning
