1	Male	41	Putti-Platt procedure; Allograft humeral head reconstruction; Coracoid transfer; Revision allograft humeral head reconstruction	4.3	-
2	Female	64	Coracoid transfer	4.6	-
3	Male	48	No previous stabilisation procedures	4.8	-
4	Male	32	Putti-Platt procedure; Bankart repair; Revision Bankart repair; Allograft humeral head reconstruction; Humeral head resurfacing	5.0	Examination under anaesthesia and arthrocentesis due to persistent pain
5	Male	51	No previous stabilisation procedures	-	-

Case	Active forward elevation in degrees (preop/postop)	Active external rotation in degrees (preop/postop)	Oxford shoulder instability score (preop/postop)	Subjective shoulder value (preop/postop)
1	130/80	30/25	5/32	0/60
2	45/80	20/20	15/37	50/70
3	60/90	10/70	6/33	20/60
4	50/150	0/45	7/16	10/50

Preop: Pre operation; Postop: Post operation.
