(Purpose)
Injuries to the superior labrum of the shoulder called SLAP lesions are often successfully managed with arthroscopic treatment. This study presents the postoperative results of the cases of arthroscopic debridement only for SLAP lesions.
(Materials and methods)
23 patients could not reflect when doing the exercises for the rotator cuff muscles and mobilization of the shoulder joint, and had SLAP lesions at the time of arthroscopy. There were 15 males and 8 females in this study. The average age at the time of surgery was 23 years, with a range of from 16 to 29 years old. The torn and frayed labral tissue was debrided back to the intact labrum with a motorized shaver vial in all cases. The postoperative follow-up average was 27 months (15-38 months).
(Results)
SLAP lesion was classified by Snyder's classification of lesions. The findings were classified as follows: Type I: 13 cases, Type II: 10 cases, Type III: 1 case and Type IV 2 cases. The mean JOA scores were as follows: (preoperative/postoperative) Type I: 86.2/96.6, Type II: 82.1/91.6, Type III: 88/100 Type IV: 89/100.
(Conclusion)
Type II means that the superior labrum and attached biceps tendon were stripped off the underlying glenoid. Many authors were said that it is necessary to promote healing of the avulsed labrum to the underlying bone. However our technique for these cases were debrided back to the intact labrum. The results of this study are sufficient enough to warrant a debridement in a labrum lesion that could enhance stability.
