Patients and Methods: Eighteen consecutive
patients with recurrent, unidirectional, posttraumatic
shoulder instability were included in
the study. All patients underwent open Bankart
reconstruction involving absorbable suture
anchors. The patients underwent serial
radiographic evaluations during a follow-up
period of 90 (80-95) months.
Results: The median age at the index operation
was 27 (16-50) years. Two patients suffered redislocations
during the follow-up period. At
follow-up the Rowe and Constant scores were 94
(63-100) and 88.5 (65-100) points respectively.
Strength measurements in 90º abduction
displayed 8.1 (3.7-17.2) kg on the index side and
7.6 (2.7-17.6) kg on the contralateral side (n.s.).
The external rotation in abduction was 80º (60-95)
compared with 100º (70-120) on the contralateral
side (p=0.0015).
Signs of minor or moderate degeneration were
found in 5/18 (28%) patients on the pre-operative
radiographs. On the 90-month radiographs 12/18
patients (67%) revealed minor, moderate or severe
degenerative changes. Compared with the preoperative
assessments there was a significant
increase in degenerative changes during the
follow-up period as seen on the seven, 33 and 90-
month radiographs, (p=0.01, p=0.03 and p=0.01
respectively). On the seven-month radiographs
2/18 patients revealed invisible or hardly visible
drill holes in conjunction with the absorbable
implants. The corresponding on the 90-month
radiographs was found in 12/18 patients (p=0.003,
seven v 90 months).
Conclusion/Discussion: In the long-term stable
shoulders were found in 16/18 patients. The
stabilisation could, however, not prevent an
increase in degenerative changes as seen on the
serial radiographs obtained until seven to eight
years after the index procedure. The drill-holes
used for absorbable implants appeared to heal in
a majority of patients during the follow-up period.

Arthroscopic Rotator Interval Closure as a
Supplement to Arthroscopic Bankart Repair for
Reccurent Anterior Dislocation of the Shoulder

Introduction: The increasing use of Arthroscopic
surgery for recurrent anterior shoulder
dislocations (RASD) has questioned the
indications and contraindications for this
procedure. The ideal candidate for this kind of
surgery is an overhead athlete, who participates in
a no contact sport, with traumatic unidirectional
anterior instability with a well-defined Bankart
lesion.
Purpose of the paper: To demonstrate that
complementing the Arthroscopic Bankart Repair
(ABR) with an Arthroscopic Rotator Interval
Closure (ARIC) the indication for Arthroscopic
management of anterior shoulder instability can
be broaden for patients who has a less defined
Bankart lesion and has additional multidirectional
Hyperlaxity.
Patients and Methods: Between January 1, 1999
and June 30, 2002, 145 patients (153 shoulders)
suffering from recurrent anterior dislocations were
treated by ABR. In the first two years, only
patients who had unidirectional instability with
no Hyperlaxity or grade 1 Hyperlaxity were
selected for this specific method of treatment.
Encouraged by the results, beginning of October
2001, in addition to the first group of patients we
started to operate patients suffering of recurrent
dislocations having grade 2 or grade 3 Hyperlaxity.
In this second group of patients we added to the
ABR an ARIC procedure. In the first group 121
shoulders whereas in the second group 32
shoulders were operated on. We used Panalok-
Panacryl (Mitek), TwinFix 3.5mm x2 Ethibond
sutures (OBL, Smith & Nephew) suture anchors or
Bioknotless (Mitek) anchors. 139 cases had one
side operated whereas in 7 cases both sides were
operated on. There were 133 male patients and 13
females in these two groups, 82 patients had the
left shoulder, 57 patients had the right shoulder
and seven patients had both shoulders operated
