Arthroscopic Bankart Repair and Rotator Interval Plication by Transglenoid Technique: Preliminary Report / 대한정형외과학회잡지

PURPOSE: To evaluate the clinical results of arthroscopic Bankart repair and rotator interval plication by the transglenoid technique on Traumatic Unidirectional Bankart Surgery (TUBS) with concomitant rotator interval widening. MATERIALS AND METHODS: From May 2002 to May 2003, 13 cases who underwent arthroscopic Bankart repair and rotator interval plication by the transglenoid technique were studied, out of the 14 cases that were diagnosed as TUBS with concomitant rotator interval widening. Follow up period was at least 1 year. Results were evaluated by Rowe score before and after surgery. RESULTS: All the cases were male. Nine cases were on the right shoulder and 4 on the left. The mean age was 22 years old (range, 14-26 years old). The mean duration from injury to operation was 4.3 (range, 1.3-10) years. The Rowe score was improved from 58.3 to 86.4 (p=0.00). Overall outcomes were excellent in 10 cases, good in 2 and fair in 1 at final follow up. There was no sulcus sign in any of the cases at the last follow up, and redislocation did not appear in any of the cases during the follow up period. CONCLUSION: In the treatment of TUBS with concomitant rotator interval widening, arthroscopic Bankart repair and rotator interval plication by the transglenoid technique have made good results.

Results According to Arthroscopic Repair Methods of Bankart Lesion (Operative Methods According to Labral Tear) / 대한정형외과학회잡지

PURPOSE: To recommend optimal surgical techniques in cases of remaining anterior instability after Bankart repair, according to the amount of remaning labrum. MATERIALS AND METHODS: Between December 1996 and April 1999, we experienced 27 pateints that have undergone arthroscopy for recurrent shoulder dislocation. They were followed over 1 year (1 year to 3 year 2 months) and classified into three groups: Group I (Arthroscopic Bankart repair by transglenoid technique); 9 cases, Group II (Arthroscopic Bankart repair by suture anchor); 11 cases, Group III (Arthroscopic Bankart repair by transglenoid technique with suture anchor); 7 cases. RESULTS: A significant difference was found between Group I and Group III patients with poor or no remaining labrum, especially in teims of shoulder stability and range of motion recovery. CONCLUSION: Arthroscopic Bankart repair by suture anchor in a shoulder that has good labrum produced a good result. However, in a shoulder with poor labrum, the combination method of transglenoid technique with suture anchor should be considered to reduce recurrency.

Arthroscopic Transglenoid Suture Technique ( Rhee's method ): Cadaveric Studies on Relationship between Pinning site and Neurovascular Structures / 대한정형외과학회잡지

Arthroscopic treatment of shoulder instability involves two techniques mainly, transglenoid suture technique and anterior anchoring system. However, anterior anchoring system has some disadvantages such as limited indication, high cost, technical difficulty and incapability to suture or reconstruct for all types of Bankart lesion. Disadvantages of transglenoid suture techniques are indirect suture tie, bump effect and possibility of the suprascapular nerve injury. The authors use modified transglenoid suture technique (Rhees method) for shoulder instability involving Bankart lesion, type II SLAP lesion and capsular laxity. The purpose of this study is to accurately describe the relationship between the major neurovascular structures and the pinning sites used in transglenoid suture technique (Rhees method). Placement of two or three arthroscopic Beath pinning sites was simulated in four fresh cadaveric shoulder specimens by placing Steinman pins into the glenoid rim under open field. The specimens were then dissected and the relationship of the pinning sites to the suprascapular nerve and suprascapular artery were recorded. In Bankart lesion repair, safe zone of pinning sites were 2 and 5 oclock in two portals in right shoulder, safe zone of pinning sites were 7 and 10 oclock in two portals in left shoulder. Safe direction of pinning was as possible as inferomedial side in scapula. In type II SLAP repair, safe zone of pinning sites were 2 oclock and just above 2 oclock of glenoid in right shoulder and 10 oclock and just above 10 oclock of glenoid in left shoulder. Safe direction of pinning was pararell to glenoid cavity and slightly superior in horizontal plane. From this study, these sites and directions appeared to be safe. Proper pinning depends on careful attention to the topographical anatomy about the shoulder.
