Labral lesions and anatomic variants have been studied by several authors in the last decade. Buford complex and sublabral recess and foramen are most common variants. 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.

SLAP 병변의 진단시에는 정상 meniscoid 상부 관절와순과 구분이 중요하다. 병변의 기전은대부분 외 회전손상에 의해 발생하게 되며 불안정한 견관절에서 이차적 안정화 구조물로 작용하게된다. 대부분 이두박근 부하검사법으로 진단할 수 있으며, 봉합나사를 이용한 관절경적 봉합술을 시행하였을 때 투구 동작을 하는 운동 선수를 제외한 대부분의 환자에서 만족스러운 결과를 나타낸다

Purpose: The purpose of this study is to measure the internal and external rotation of shoulder and compare with normal volunteer and patients diagnosed as SLAP lesion. Materials and Methods: Thirty-eight cases (group 1) who had SLAP lesions at shoulder arthroscopy and fourty young volunteers(group 2) were analyzed retrogradely with medical record, intra-operative arthroscopic photo & video for SLAP lesions and the ROM of shoulder Under the interscalene anesthesia, the range of motion of internal rotation and external rotation were measured on flxed scapula and 90 degree abduction of shoulder, and the same method for group 2. We analyzed the results with two sample T-test and Wisconsin signed ranks test. Results: There was a significant difference between group 1 and group 2 for the ROM of shoulder. (IR; p<0.001,ER; p<0.001).For the group 1, internal and external rotation with the arm abducted 90 averaged 50 and 64 degrees and for the group 2, internal and external rotation averaged 77 and 90 degrees with significant difference(IR; p<0.001,ER; p<0.001).Conclusion: The range of motion of shoulder, especially internal and external rotation significantly decreased in SLAP lesions. Our results suggest that a limited rotational motion of shoulder closely related with SLAP lesion.

SLAP(Superior labrum anterior to posterior) lesion is found in superior labrum injury alone and also combined with extension of the Bankart lesion(anteroinferior labral tear) in recurrent shoulder dislocation patients and rarely accompanied by the posterior Bankart lesion. There have been reports about SLAP lesions associated with various lesions, however, posterior type II SLAP lesion associated with posterior Bankart lesion has been rarely reported. In such a case, there are important technical tips in inserting anchors and suturing during arthroscopic repair. We experienced a rare case of posterior type II SLAP lesion associated with posterior Bankart lesion, occurred not after repetitive throwing(common mechanism) but after trauma in slipping down with the arm stretched during riding a bicycle. The satisfactory result was obtained after arthroscopic repair in this case.

Spinoglenoid cyst have been reported in small series in the orthopaedic literature in association with SLAP lesion, which is one of less common causes of shoulder pain. Authors experienced one case of spinoglenoid cyst with SLAP lesion initially missed with ultrasonographic examination and physical examination. This case was confirmed by MRI, EMG and arthroscopic surgery was done. When clinicians cannot find a definite cause of shoulder pain and decreased power of rotator cuff tendon with ultrasonographic examination, they need further study such as MRI and EMG with careful physical examination. Clinicians need to aware of the limitation of ultrasonography for spinoglenoid cyst especially, (1) cyst size is small, (2) location of cyst is too deep to detect and along the scapula spine from SLAP lesion.

Purpose: There are many known treatment modalities for spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy. However, to the author's knowledge, there is no report on the follow-up outcomes focused on remnant cysts. Materials and Methods: Six (n=6) patients with spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy, with a mean follow-up of 15 months (12-23months) following arthroscopic cyst decompression and superior labral repair, were enrolled. Residual cyst was investigated by ultrasonography and MRI. Results: Immediate postoperative ultrasonography revealed complete remission of ganglion cyst in one patient and reduced ganglion cyst size in five patients. Three-month follow-up ultrasonography showed spontaneous complete remission of the residual cysts in all patients. No recurrence on MRI was seen at one-year follow-up. Conclusion: Residual spinoglenoid ganglion cyst remaining after arthroscopic decompression and superior labral repair tends to resolve spontaneously within 3 months of surgery.

Purpose: The purpose of this study is to check the range of motion of shoulder and inverstigate the frequencies and patterns of partial thickness rotator cuff tear in SLAP lesions. Materials and Methods: Forty-six patients, forty-seven cases who had SLAP lesions at shoulder arthroscopy were analyzed spectively using the medical records, intra-operative arthroscopic photo & video for SLAP lesions and rotator cuff articular side partial tear. Under the interscalene anesthesia, the range of notion of foreward elevation, internal rotation and external rotation was measured on fixed scapula and 90 degree abduction of the shoulder. Results: The rang of Motion are 150 degree on foreward elevation, 65.5 degree on external rotation, 61.7 degree on internal rotation. By Snyder's classification, type ll SLAP lesion is noted in 24 cases (five cases in type 1, one case in type IV). Rotator cuff articular side partial tear is noted in 24 cases ( one case in type I, 22 cases in type II, one case in type IV SLAP). All the rotator cuff articular side partial thickness tear were located in the anterior part of the supraspinatus. Conclusion: The rotator cuff partial thickness tear is mostly noted on the articular side and frequently found in the relatively more unstable type of SLAP lesions. So we consider that SLAP lesion may be a one of the causes for partial tear of the rotator cuff articular side.

Purpose: The purpose of the study is to evaluate the usefulness of CT arthrography (CTA) by conducting a comparative study of CTA and MR arthrography (MRA) with the arthroscopic findings in the same patients. Materials and methods: Forty nine patients who suffered from shoulder disease underwent MRA and CTA concurrently. The sensitivity and specificity of CTA was evaluated, as compared to MRA, in the case of four types of shoulder pathological lesions. The accuracy of CTA was evaluated by analyzing the arthroscopic findings of thirty four patients. Results: Compared to MRA, CTA showed a sensitivity of 90% and a specificity of 100% for diagnosing supraspinatus tendon (SST) full thickness tear, and CTA showed a sensitivity of 100% and a specificity of 97.5% for making the diagnosis of superior labrum anterior to posterior (SLAP) lesion. For diagnosing partial articular side supraspinatus avulsion (PASTA) lesion, some studies have shown the usefulness of CTA with a sensitivity of 71.4% and a specificity of 97.7%. However, for diagnosing SST bursal side partial tear, the sensitivity of CTA was as low as 10%. CTA has been shown to be relatively accurate when the diagnoses were verified with the arthroscopic findings; diagnosing SST full thickness tear and SLAP lesion with CTA has shown an accuracy of 100% and87.5% respectively, and CTA showed 71.4% diagnostic accuracy for PASTA lesion. Conclusion: CTA was a useful tool and it was equivalent to MRA for the assessment of SST full thickness tear, SLAP lesion and PASTA lesion, but not bursal side partial tear. Thus, it may be used preferably to diagnose shoulder pathology and for follow up as an inexpensive tool after operation.
