Background: The consensus is that a bony Bankart lesion shorter than 25% of the length of glenoid does not affect the clinical result; hence, such lesions were often neglected. However, small bony Bankart lesions are associated with various types of capsulolabral lesions. Methods: A total of 82 patients who had undergone arthroscopic capsulolabral lesion repair surgery for anterior shoulder dislocation were reviewed. The prevalence rates of early and late type of capsulolabral lesions were compared between a group of patients with and a group without small bony Bankart lesions. In addition, the types of accompanying capsulolabral lesion were analyzed according to the type of bony Bankart lesion. Finally, the clinical outcomes were evaluated (active range of motion, American Shoulder and Elbow Surgeons score and Rowe's score). Results: Among the 13 patients who had small bony Bankart lesions, the prevalence rate of early and late type of capsulolabral lesions was 38.5% and 61.5%, respectively. Among the 69 patients without bony Bankart lesion, the prevalence rates of early and late type of capsulolabral lesions were 74% and 26%, respectively. Significantly worse clinical outcome was observed for the group of patients with both small bony Bankart lesions and late type of capsulolabral lesion. Conclusions: More severe type of small bony Bankart lesion appears to be associated with late type of capsulolabral lesion. The significantly worse clinical outcome for patients with both small bony Bankart lesion and late type of capsulolabral lesion indicates that small bony Bankart lesions cannot always be neglected.

We introduce arthroscopic Bankart repair technique using antegrade suture passer that can effectively restore detached anteroinferior capsulolabral complex for shoulder anterior instability. After diagnostic arthroscopy is performed using posterior, anteroinferior and anterosuperior portals, we confirm Bankart lesion and perform debridement and decortications of anteroinferior glenoid edge and neck. Suture anchor is inserted through anteroinferior portal at 2 mm medial side of glenoid edge (4:30 direction). Scorpion$^{TM}$ loaded suture is directly advanced to detached and retracted anteroinferior capsulolabral complex and the suture is passed at 10~15 mm medial side of detached anteroinferior capsulolabral complex (5:30 direction). The suture is retrieved by Scorpion's hook and then is tied using samsung medical center (SMC) sliding knot technique. Then suture anchors are serially inserted (2:30, 3:30) and capsulolabral complex repair is performed using suture hook and suttle-relay technique. This technique that can obtain anatomical restoration of anteroinferior glenohumeral ligament with proper tension is useful technique to reduce postoperative recurrence and makes it possible for less experienced surgeons.

Background: Recent studies have reported high rates of recurrence of shoulder instability in patients with glenoid bone defects greater than 20% after capsulolabral reconstruction. The purpose of the present study was to evaluate the failure rate of arthroscopic capsulolabral reconstruction for the treatment of anterior instability in the presence of glenoid bone deficits >20%. Methods: Retrospective analyses were conducted among cases with anterior shoulder instability and glenoid bone defects of >20% that were treated by arthroscopic capsulolabral reconstruction with a minimum 2-year follow-up (30 cases). We included the following variables: age, bone defect size, instability severity index score (ISIS), on-/off-track assessment, incidence recurrent instability, and return to sports. Results: The mean glenoid bone defect size was 25.8%±4.2% (range, 20.4%-37.2%), and 18 cases (60%) had defects of >25%. Bony Bankart lesions were identified in 11 cases (36.7%). Eleven cases (36.7%) had ISIS scores >6 points and 21 cases (70%) had off-track lesions. No cases of recurrent instability were identified over a mean follow-up of 39.9 months (range, 24-86 months), but a sense of subluxation was reported by three patients. Return to sports at the preinjury level was possible in 24 cases (80%), and the average satisfaction rating was 92%. Conclusions: Arthroscopic soft tissue reconstruction was successful for treating anterior shoulder instability among patients with glenoid bone defects >20%, even enabling return to sports. Future studies should focus on determining the range of bone defect sizes that can be successfully managed by soft tissue repair.

Superior labrum anterior to posterior (SLAP) lesions of the shoulder has recently been a popular issue to shoulder surgeons. Now we are correlating many shoulder symptoms to this SLAP lesion. A 45 year-old female patient injured her shoulder when her arm sleeve was entrapped in moving automobile door. A forceful pull of the arm in external and abduction position was suspected. She complained continuous shoulder pain with limited range of motion for 2 months. Magnetic resonance image showed possible SLAP lesion but no definite diagnosis were made prior to the operation. Arthroscopic evaluation revealed SLAP type Ⅱ lesion with concomitant avulsion of the superior glenoid cartilage. In addition anterior labrocapsular tear was seen from 7 to 9 o'clock of anterior glenoid. The SLAP lesion and the anterior capsulolabral lesion were repaired properly to the glenoid. We report a case of glenoid-cartilage avulsion type of SLAP Ⅱwith anterior labrocapsular lesion.

Background: The study aimed to determine the type of capsular insertion and the extent of capsular elongation in anterior shoulder instability by quantitatively evaluating their computed tomography arthrographic (CTA) findings, and to investigate the correlation of these parameters with surgical outcomes. Methods: We retrospectively reviewed 71 patients who underwent CTA and arthroscopic capsulolabral reconstruction for anterior shoulder instability between April 2004 and August 2008. The control group comprised 72 patients diagnosed as isolated type II superior labrum anterior to posterior (SLAP) lesion during the period. Among the 143 patients, 71 were examined with follow-up CTA at an average 13.8 months after surgery. It was measured the capsular length and cross-sectional area at two distinct capsular regions: the 4 and 5 o'clock position of the capsule. Results: With regards to the incidence of the type of anterior capsular insertion, type I was more common in the control group, whereas type III more common than in the instability group. Anterior capsular length and cross-sectional area were significantly greater in the instability group than in the control group. Among patients of the instability group, the number of dislocations and the presence of anterior labroligamentous periosteal sleeve avulsion lesion were significantly associated with anterior capsular redundancy. Postoperatively, recurrence was found in 3 patients (4.2%) and their postoperative capsular length and cross-sectional area were greater than those of patients without recurrence. Conclusions: Capsular insertion type and capsular redundancy derived through CTA may serve as important parameters for the management of anterior shoulder instability.

Purpose: Point fixation at the margin of the glenoid is a limitation of conventional arthroscopic stabilization using suture anchors, and does not afford sufficient footprint healing, especially in glenoid bone deficiency. So, we introduce an arthroscopic suture bridge transosseous-equivalent technique for bony Bankart lesions to avoid the technical disadvantage of point contact with anchor fixation and to improve mechanical stability through cross compression of the labrum. Surgical approach: The technique was adapted from the transosseous-equivalent rotator cuff repair technique using suture bridges, which improved the pressurized contact area and mean pressure between the tendon and footprint. After preparation of the glenoid bed by removal, reshaping, or mobilization of the bony lesion, two anchors (3.0 mm Biofastak, $Arthrex^{(R)}$, Naples, FL) were inserted into the superior and inferior portion of the bony Bankart lesion. Using a suture hook, medial mattress sutures were applied around the capsulolabral portion of the IGHL complex to obtain sufficient depth of glenoid coverage. A 3.5 mm pushloc anchor ($Arthrex^{(R)}$, Naples, FL) hole was made in the articular edge of the anterior glenoid rim. distal, suture bridge was applied, and proximal was inserted to mobilize the labrum in the proximal direction. This avoided the technical disadvantage of point contact with anchor fixation and decreased the level of gap formation through cross-compression of the labrum.

Purpose: An osseous defect in the glenoid and humeral head is closely associated with recurrence of anterior shoulder instability. The purpose of this article is to describe the open surgical techniques and introduce our experiences with anterior instability with a significant osseous defect. Materials and Methods: We reviewed the articles that have focused on and/or mentioned the affect of osseous defects on anterior shoulder instability. The open surgical techniques and its related pearls are summarized in this review. Results: Accurate evaluation for the size and location of the osseous defect is critical for preventing recurrence after restoration of the anterior capsulolabral structure. The glenoid bone restoration techniques include the coracoids transfer (the Bristow procedure and the Latarjet procedure) and a structural iliac bone graft. Rotational humeral osteotomy and an osteoarticular allograft could be used for repairing a significant posterosuperior humeral defect (Hill-Sachs lesion). Shoulder arthroplasty may be tried for treating a humeral bone defect, but more study on this is needed. Conclusion: Open surgical restoration decreases the risk of recurrence anterior shoulder instability that is combined with a significant osseous defect. Arthroscopic surgery currently has limitations for treating an osseous defect, but it will become useful in proportion to the development of arthroscopic instruments and techniques in the future.
