Purpose: The results of the repair for the superior labrum lesions attaching at the superior glenoid have not been satisfactory in every cases. We wanted to analyze the shoulder MRI and the anatomical morphology and pattern of the superior glenoid at which the superior labrum attaches to get anatomical information helpful in treating the superior labrum. Materials and Methods: We analyzed the coronal images of the shoulder MRI of 108 cases taken at our hospital. Average age was 52 years (range, 17~71 years), 55 males and 53 females. On two coronal images behind the attachment of the long head of biceps that the repair of the SLAP was performed at, the length of the attachment of superior labrum and the angle of the supero-lateral glenoid were measured. Results: The average length of the attachment of superior labrum was $9.78{\pm}1.64\;mm$. The average length was $10.1{\pm}1.61mm$ in male, $9.43{\pm}1.6\;mm$ in female. The angle of the supero-lateral glenoid was $89.6{\pm}7.6$ degrees. Conclusion: The attachment of the superior labrum in coronal plane was shorter in posterior spot than anterior. The angle of the supero-lateral glenoid was less in posterior spot.

Purpose: Labral lesions and its anatomic variants have been studied by several authors in the last decade. Buford complex and sublabral recess are most common variants. Their recognition is important in order to distinguish them from superior and anterior labral tear. Materials and Methods: We report one case of a 19-year-old female who was mistaken SLAP lesion for normal variant and was treated with arthroscopic surgery. Results: The arthroscopic finding shows rare normal variant of biceps anchor and superior labrum. The biceps long head tendon was inserted at superior labrum and supraspinatus tendon area. This finding was mistaken to SLAP lesion. Conclusion: We report rare normal variant of biceps anchor and superior labrum that was observed during arthroscopic surgery for SLAP lesion.

Their recognition is important in order to distinguish them from superior and anterior labral tear. We report rare normal variant of biceps anchor and superior labrum that was observed during arthroscopic surgery for SLAP lesion.

Most of the caicific tendinitis have been reported to be found on the rotator cuff, in particularly on supraspinatus. We reported a case of calcific tendinitis on the posterosuperior glenoid labrum. The location of the lesion was diagnosed accurately by the MRI and easily removed the lesion with arthroscopic surgery and got satisfactory results.

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.

일반적으로 견관절의 전방안정력은 하관절와상완인대에서 주역할을 하며, 불안정성으로 인한 병변은 관절순과 골관절와사이의 분리(Bankart lesion)로 나타난다고 한다. 중관절와상완인대는 특히 중등도의 외전위치에서 견관절의 전방안정성에 중요한 역할을 하는 정적 안정물로써, 다른 관절와상완인대의 동반손상없이 단독으로 파열된 례는 문헌고찰상 보고된 바가 없었다. 본 증례의 경우 특별한 외상력없이 내원 1년전부터 우측 견관절의 전방 불안정성과 동통성운동제한의 소견을 보였으며 상기 증상은 3개월 전부터 점차 악화되었다. 관절경 소견상 관절와순 부착부위에서 파열된 중관절와상완인대를 확인할 수 있었으며 동반된 관절와순의 부분파열 및 관절와관절면의 미란을 확인할 수 있었다. 파열된 중관절와상완인대와 비후된 활막을 변연절제 후 8개월 정도의 단계적 재활운동을 시행하였으며 동통과 관절운동의 회복소견을 볼 수 있었다. 본저자들은 관절경검사상 중관절와상완인대의 단독파열소견을 보인 39세의 여교사를 치료하였으며 그 결과를 문헌고찰과 함께 보고하는 바이다.

Glenoid labrum acts as one of static stabilizer of the glenohumeral joint. It deepens the glenoid socket and may also serve as a chock, acting as a wedge in preventing glenohumeral translation. Two types of variations in labral anatomy were noted by Detrisac and Johnson. Type A has a superior labrum that is detached centrally but well attached peripherally. The type B labrum is well attached centrally and peripherally at all sites. A meniscoid-type labrum is thought to be normal unless there are splits or fragmentation of the overlying labral tissue. Meniscoid type labrum is different from SLAP II lesion in that it has a firm anchoring on the superior labrum. We observed four cases that had a meniscoid variant superior labrum, which covered the superior glenoid unusually larger than normal in the arthroscopic treatment of shoulder pathology including instability and rotator cuff diseases. We did arthroscopic reshaping and debridement of meniscoid variant superior labrum combined with pathologic change of the glenohumeral joint. Further study would be required for understanding the mechanism of the development of meniscoid variant labrum and its clinical significance.

Purpose: Too develop a flexible drill device that can be inserted into the shoulder joint so that arthroscopic transosseous suture repair for Bankart lesion is possible. Materials and Methods: We created a device composed of a flexible drill unit and a guide pipe unit. The flexible drill unit was made of flexible multifilament wires (1.2 mm in diameter) that was twisted into one cord so that it can flex in any direction and a drill bit (1.2 mm in diameter) that is attached onto one end of the flexible wire. The guide pipe unit was a 150 mm long metal pipe (2.0 mm in inner diameter and 3.0 mm in outer diameter), with one end bent to 30 degrees. The flexible drill set was inserted into the shoulder joint through the posterior portal of the joint. The guide pipe component was placed onto the medial wall of the glenoid so that the pipe was placed 5 mm posterior to the margin of the anterior glenoid rim. The flexible drill was driven through the glenoid by the power drill so that holes were made in the glenoid. A non- absorbable suture was passed through the hole. Tying of a sliding knot tying was accomplished over the capsule and labrum after making a stitch through the capsule and labrum with a suture hook loaded with suture passer. The same procedures were done at the 2 and 4 O'Clock positions of the glenoid. Results: Five cases with Bankart lesion received arthroscopic transosseous repair with our flexible drill device. There were no intraoperative problems. Neither redislocation nor subluxation was reported at final follow-up. Conclusion: Arthroscopic transosseous suture repair without suture anchors and easy tying of a sliding knot are possible with a flexible drill set.
