(Purpose) The purpose of this study was to evaluate the diagnostic value of air CT arthrography for SLAP lesion of the shoulder joints.
(Patients & Methods) We studied 184 shoulders that underwent operative findings. One hundred and forty-one shoulders were anterior instabilities,26 shoulders were SLAP lesions and 17 shoulders were both in preoperative diagnosis. The mean age at operation was 23 years (15-40). Air CT arthrography was performed prior to surgery. Type 2 SLAP lesion was diagnosed by existence of trapped air sign between superior labrum and glenoid rim.
(Results) Type 2 SLAP lesion were diagnosed in 33 shoulders by air CT arthrography. According to Snyder' s classification,14 shoulders were type 1,49 shoulder were type 2,4 were type 3 and one shoulder was type 4 in operative findings. Air CT arthrography demonstrated 55% sensitivity,94%specificity and 84% accuracy in the diagnosis of type 2 SLAP lesion.
(Conclusions) Air CT arthrography were useful for preoperative diagnosis of type 2 SLAP lesion.
