BACKGROUND
This study was performed to define the dimensions of the rotator interval (RI) in adhesive capsulitis using magnetic resonance (MR) arthrography preoperatively to clarify and evaluate pathology.
METHODS
We performed a retrospective review of a series of 73 shoulders that underwent MR arthrography. The shoulders were grouped according to their diagnosis: group I comprised 47 shoulders without adhesive capsulitis; group II comprised 26 shoulders with adhesive capsulitis. Using MR arthrography, we estimated the height, base, RI area, width, RI index, and RI ratio.
RESULTS
The group II shoulders differed significantly in height, base, RI area, RI index, and RI ratio from the group I shoulders. There were statistically significant differences in RI dimensions between patients with and without adhesive capsulitis of the shoulder.
CONCLUSIONS
Estimating the dimensions of the RI in adhesive capsulitis using MR arthrography may prove to be valuable for assessing patients preoperatively.
背景
本研究旨在通过术前磁共振（MR）关节造影确定粘连性关节囊炎中旋转间隙（RI）的尺寸，以阐明和评估病理情况。
方法
我们对一系列73例接受MR关节造影的肩部进行了回顾性研究。根据诊断将肩部进行分组：第一组包括47例无粘连性关节囊炎的肩部；第二组包括26例有粘连性关节囊炎的肩部。通过MR关节造影，我们估计了高度、底部、RI面积、宽度、RI指数和RI比率。
结果
第二组肩部在高度、底部、RI面积、RI指数和RI比率方面与第一组肩部有显著差异。有肩部粘连性关节囊炎和无肩部粘连性关节囊炎的患者在RI尺寸上存在统计学显著差异。
结论
使用MR关节造影估计粘连性关节囊炎中RI的尺寸可能被证明对术前评估患者有价值。
