on. In 78 cases the dominant and in 75 cases the non-dominant shoulder were involved. In 10 cases the Arthroscopic procedure was used to review and to correct failed Arthroscopic (6 cases) or open (4 cases) stabilization procedures. Additional findings: in 87 cases an ALPSA lesion was corrected, and in 15 cases an additional superior labral lesion was repaired and in 4 cases a small osteochondral fragment (bony Bankart lesion) was removed. The mean follow-up was 2.2 years ranging between 3.5 to 1.1 years. Results: In spite of the relatively short follow-up for the second group of patients we encountered very good preliminary results. At revision of all the cases we found 9 recurrences for the ABR group (rePresenter 7.43%) in comparison of the one reoccurrence in the ABR supplemented by ARIC procedure (3.12%) thus indicating that recurrent shoulder dislocations associated with multidirectional Hyperlaxity should be treated arthroscopicaly. The operating time was pronged with an average of 14 minutes for the ARIC procedure. The average shortened external rotation was 9 degrees in the second group compared to the 6 degrees encountered in the ABR group. Longer rehabilitation period was needed in the ARIC group due to shortened external rotation. Conclusions: The ARIC is a new technique that permits a strong reliable closure of the Rotator Interval. This technique broadens the indications for Arthroscopic shoulder surgery as a solution for recurrent dislocations associated with joint Hyperlaxity. Key words: shoulder instability, Hyperlaxity, rotator interval closure, arthroscopy. E-poster w/ Standard #869 Latarjet Procedure for Anterior Shoulder Instability in Rugbymen Elias Dagher, Paris, FRANCE, Presenter Bertrand Sonnery-cottet, Lyon, FRANCE LaurentNova-Josserand, Lyon, FRANCE Gilles Walch, Lyon, FRANCE Clinique Sainte Anne Lumiere, Lyon, FRANCE Introduction: Rugby players have been reported to be at high risk for failure after shoulder stabilisation for anterior shoulder instability. We report the results of the Latarjet procedure in 85 rugbymen shoulders with a mean follow-up of 7 years. Materials and Methods: Retrospective analysis of 1518 patients who underwent open stabilisation for anterior shoulder instability by the Latarjet procedure in our department between 1988 and 2002 revealed 125 rugby players. 85 shoulders in 79 patients were reviewed for this study with a mean follow-up of 7 years (range,1-15). The average age was 19.5 years (range,12-40). 46 patients had a national or international level. 60 patients had recurrent dislocations and 19 patients had recurrent subluxations. Pre-operative X-rays revealed 56 osseous Bankart lesions (66%) and 53 Hill-Sachs lesions (62%). The mean interval between instability and surgery was 33 months (range, 2-288). At the last follow-up patients were questioned about the return to sports. They were further evaluated according to the Duplay score system. Results: 93% of the patients were satisfied (40%) or very satisfied (53%). 53 patients (67%) returned to playing rugby in an average time of 6 months (range, 3-24). 16 patients (20%) decided to give up for reasons unrelated to their shoulder. Rate of recurrent instability was 7%, one patient (1,1%) sustained a dislocation (pseudarthrosis due to biodegradable screw fixation) and subluxation occurred in 5 patients (5,8%). The average Duplay score was 76 points. 89% of the patients had excellent (36%) or good (43%) results. Better results were observed in patients who were operated in the first year after the occurrence of instability (Duplay score=84, 42% excellent and 51% good results). Conclusion: The Latarjet stabilisation procedure is a safe and efficient procedure in anterior shoulder instability. Post-operative stability appears to be satisfactory in this population in camparison to that reported with other techniques. We still recommend it in contact sports. E-poster w/ Standard #870 Arthroscopic Bankart Repair using Knotless or BioKnotless Suture Anchors Matthew Nofziger, Bennington, VT, USA, Presenter Raymond Thal, Reston, VA USA Mark Bridges, Reston, VA USA Town Center Orthopaedic Associates, Reston, VA, USA A retrospective evaluation of 73 consecutive patients with traumatic anterior instability of the shoulder treated with arthroscopic Bankart repair using Knotless or BioKnotless Suture Anchors is reported. Results at a minimum 2-year follow-up
(range 2-7 years) are reported on 72 patients available for follow-up evaluation. The study population consisted of 57 males and 15 females at an average age of 27 years (range 15-64). Thirty-seven of the patients were 22 years of age or younger. The average duration of preoperative symptoms was 55 months (range1- 300 months). All patients had an initial traumatic event and recurrent instability. Forty-seven patients had preoperative dislocations (average 2.3 dislocations) and 47 patients had recurrent subluxations (average 6.1 episodes). Metallic Knotless suture anchors were used in 45 patients; BioKnotless suture anchors were used in 27 patients. Forty patients in this study were athletes involved in contact or collision sports. The average postoperative loss of external rotation, at 90 degrees of abduction, was one degree. Five patients (6.9%) experienced a postrepair dislocation. Redislocation rate was 8.8% in the Metallic Knotless anchor group (4 of 45 patients) and 3.7% in the BioKnotless anchor group (1 of 27 patients). All patients who experienced a post-repair dislocation were 22 years old or younger. Redislocation rate in this age group was 13.5% (5 of 37 patients). There were no redislocation episodes in patients over 22 years of age. Two of the post-repair dislocations were in patients involved in contact or collision sports (7.5% redislocation rate). Revision arthroscopic repair using Knotless suture anchors was performed on 4 of the 5 patients who experienced redislocation. Three remained stable at last follow-up of a minimum of 2 years. E-poster #871 Arthroscopic Bankart Repair Using Anchor Suturing and Thermal Capsulorrhaphy for Traumatic Anterior Instability of the Shoulder Shigeru Sasaki, Kashiwazaki, JAPAN, Presenter Akihiro Kotani, Mitaka, Tokyo, JAPAN Masahiko Kemmochi, Setagaya-ku, Tokyo, JAPAN Yoshiaki Ishii, Mitaka, Tokyo, JAPAN Kazuhiko Satomi, Mitaka, Tokyo, JAPAN Dept. of Orthop. Surg., Kashiwazaki Chuo Hospital, Kashiwazaki, JAPAN average age of 27.6 years (range: 16-53) at the time of operation. Each subjects Bankart lesion was identified and mildly decorticated; capsulolabral tissue was mobilized by using an abrader burr and meniscal rasp, then 3 or 4 absorbable PLLA suture anchors were implanted. The capsule was sutured to the anterior margin of the glenoid with the anterior inferior glenohumeral ligament complex to provide restraint. Then, thermal capsular shrinkage was performed mainly on the unstable anterior and anteroinferior aspects of the capsule, at 20 W and at an average temperature of 67.3, using the Mitek bipolar VEPR system. Postoperatively, immobilized with a sling with a pillow spacer for 3 weeks. A physical therapist began mild assistedpassive movements of abduction at 10 days after the operation; then, activities were increased toward full sporting participation at 6 months. The clinical treatment results were assessed based on Rowe score, recurrence of dislocation/subluxation, and average range of motion (ROM) limitations of passive external rotation at 0 and 90 degree of abduction. Preoperatively, none of the patients had an overall rating of good or excellent according to the system of Rowe et al.; however, our results indicated that 94.4% (17 of 18 patients) had a rating of good or excellent at the time of the final follow-up, except for one patient who had recurrent subluxation after the surgery. The average ROM limitations of passive external rotation at 0 and 90 degree of abduction measured 6.6 and 5.8 degrees. Mologne et al. reported that 75% of unsuccessful arthroscopic Bankart repair operations were associated with capsular laxity. Gartsman et al. reported that the combination of suture anchor and thermal capsulorrhaphy (with a Holmium laser) was effective in cases with traumatic anterior instability of the shoulder. Our results also indicated that the instability was reduced by eliminating the laxity of the anterior aspect of the capsule through arthroscopic Bankart repair with thermal capsular shrinkage. This study describes the clinical results of arthroscopic Bankart repair using anchor suturing and thermal capsular shrinkage for traumatic anterior instability of the shoulder in 18 patients with an average follow-up of 22.9 months. The subjects were 12 males and 6 females, with an
