THE RELATIONSHIP BETWEEN THE MORPHOMETRIC PARAMETERS OF SCAPULA AND SUPRASPINATUS TENDINITIS

42382

OBJECTIVE: Tendinitis is one of the most frequent shoulder lesions. The aim of this study is to evaluate the correlation of the radiological parameters including critical shoulder angle (CSA), glenoid inclination (GI) and acromion index (AI) with supraspinatus tendinitis. MATERIAL AND METHODS: Seventy-four patients (47 men, 27 women, mean age 29±5.2 (range 18- 40)) were included in the study. Two groups were formed as Group I (n=33) and Group II (n=41) according to supraspinatus tendon intensity revealed by shoulder magnetic resonance images. Critical shoulder angle, glenoid inclination and acromion index parameters were measured on shoulder radiographs obtained in neutral position. The relationship of the radiologic parameters and the presence of supraspinatus tendinitis were evaluated. RESULTS: The mean CSA was 37.9°, the mean GI was 17.2°, and the mean AI was 0.8 in Group I. The mean CSA was 38.3°, the mean GI was 17.1°, and the mean AI was 0.8 in Group II. No statistically significant difference was found between the groups. The CSA values of the women were statistically significantly higher than that of the men (p=0.04). CONCLUSIONS: Higher CSA values are found to be associated with the risk of rotator cuff tear and lower CSA values with osteoarthritis. Higher angles are associated with increased risk of supraspinatus tendinitis tear. Supraspinatus tendinitis is not associated with the morphometric parameters including CSA, AI and GI. New morphometric parameters should be identified and their relation with supraspinatus tendinitis should be investigated for early diagnosis.
