Concerning the radiological evaluation of the modified Bristow procedure in the operative treatment of recurrent anterior dislocation of the shoulder, several aspects are of importance. In the first place, the position of the coracoid transplant and the screw used to fix it with should be underneath the equator of the humeral head and within 1 cm of the glenoid rim. Secondly, bony union appears to take place in most instances in which the screw has enough length to reach the posterior cortex of the scapular neck. However, when the screw is too short, in most cases a fibrous union develops. These features can be demonstrated on three routine radiological examinations: the anatomical anterior-posterior view, the axial projection with internally rotated humerus and the axial view with the arm in external rotation.
关于改良布里斯托手术治疗复发性肩关节前脱位的放射学评估，有几个方面很重要。首先，喙突移植骨及用于固定它的螺钉的位置应在肱骨头赤道下方且距关节盂边缘1厘米以内。其次，在大多数情况下，当螺钉长度足够到达肩胛颈后皮质时会发生骨愈合。然而，当螺钉过短时，大多数情况下会形成纤维性愈合。这些特征可在三种常规放射学检查中显示出来：解剖学前后位片、肱骨内旋时的轴位片以及手臂外旋时的轴位片。
