腱板断裂に随伴した肩甲上腕関節内病変 The Incidence of Glenohumeral Joint Abnormalities Concominant to Rotator Cuff Tears
[Purpose]To evalutate the incidence of glenohumeral joint abnormalities concominant to rotator cuff tears.<BR>[Materials and Methods]305 patients who underwent an arthroscopic examination of glenohumeral joint and a rotator cuff repair were studied. The average age of the patients was 58.8years and they consisted of 213 men and 92 women. The rotator cuff tears included 239 complete tears and 66 incomplete tears. The diagnosis of the joints was determined by an arthroscopy.<BR>[Results]Synovitis with a villous formations at the superior capsule were found in 152 cases(50%), at the rotator interval in 177(58%)and at the axillary pouch in 19(6.2%). Type 1 SLAP lesions were found in 52 cases(17%), type II in 14(4.6%), type III in one(0.3%)and type IV in 2(0.7%). Bankart lesions were in cases(1%). Partial tears of the long head of biceps tendon were in 34cases(11%), com-Plete tears in 15(4.9%)and dislocation of the tendon in 2(0.7%). Osteoarthrotic change of the glenoid were in 18 cases(5.9%), of the humeral head in 29(9.5%)and free bodies in 3(1%).<BR>A Total of 239 cases(78%)out of 305 had glenohemeral joint abnormalities and 72 cases(24%)needed arthroscopic treatments or a change of post operative rahabilitation.<BR>[Conclusion]Glenohumeral joint abnormalities concominant to rotator cuff tears can sometimes be overlooked because they are masked by the pathology from a rotator cuff tear. Using an arthroscopy as a rotator cuff repair has the advantages of both an examination and treatment of the glenohumeral joint.
