The purpose of this paper is to report on our clinical findings and operative results of SLAP lesion in throwing athletes. Eighteen throwing shoulders underwent arthroscopic superior labrum repair. Snyders procedure was performed using Mini Revo anchors or a Revo anchor in all the patients. One anchor was used in 16 shoulders and two anchors were used in 2 shoulders. The average age at the operation was 24.7 years old (range : 16 - 51). There were 17 baseball players (11 pitchers and 6 fielders) and one badminton player. In all the shoulders superior labrum detachments were recognized on MR arthrography. Eleven patients complained of pain during the cocking phase and 6 patients complained of pain at ball release. Only one patient had pain with follow through. Crank test was positive in all 18 shoulders (100%). Seventeen of 18 patients had pain on anterior apprehension test (94%). Mimori test was positive in 14 of 18 shoulders (78%). OBrien test was positive in 12 of 16 shoulders (75%). Arthroscopic evaluation revealed type 2 SLAP lesion in 17 shoulders and type 3 in one shoulder. Fourteen patients were followed up over 12 months after arthroscopic surgery. Twelve of these 14 patients were able to return to their previous levels. Complete return rate was 86%. The average duration between the operation and the return was 8.4 months (range : 6 - 11) in 7 pitchers and 6.8 months (range : 5 - 8) in 4 fielders. Crank test, anterior apprehension test, Mimori test and OBrien test are beneficial to diagnose as SLAP lesion. The results of arthroscopic superior labrum repair for SLAP lesion in throwing athletes were good.
