Abstract
|
|
|
Purpose: The results of the repair for the superior labrum lesions attaching at the superior glenoid have not been satisfactory in every cases. We wanted to analyze the shoulder MRI and the anatomical morphology and pattern of the superior glenoid at which the superior labrum attaches to get anatomical information helpful in treating the superior labrum.
Materials and Methods: We analyzed the coronal images of the shoulder MRI of 108 cases taken at our hospital. Average age was 52 years (range, 17~71 years), 55 males and 53 females. On two coronal images behind the attachment of the long head of biceps that the repair of the SLAP was performed at, the length of the attachment of superior labrum and the angle of the supero-lateral glenoid were measured.
Results: The average length of the attachment of superior labrum was 9.78±1.64 mm. The average length was 10.1 ± 1.61mm in male, 9.43±1.6 mm in female. The angle of the supero-lateral glenoid was 89.6±7.6 degrees.
Conclusion: The attachment of the superior labrum in coronal plane was shorter in posterior spot than anterior. The angle of the supero-lateral glenoid was less in posterior spot.
