鏡視下Bankart 修復術前後のMR arthrography による評価

抄録

The purpose of this study was to evaluate Bankart lesion on MR arthrographies (MRA) at pre and post arthroscopic Bankart repair.23 patients with traumatic shoulder instability who had undergone arthroscopic Bankart repair were studied. There were 24 men and 3 women (ave.24.6 y. o). The minimal follow-up period was 1-year. The labral height (LH), glenoid depth (GD), and balance stability angle (BSA) were measured on 2slices at axial images of MRA. One slice passed through the center of the glenoid and another passed the inferior quarter of the glenoid. As clinical evaluations, the existence of re-dislocations were assessed at 1year after the surgery. A re-dislocation was recognized in 3patients. After the surgery, LH, GD, and BSA were significantly improved both center-slice and inferior-slice.
