A new radiologic sign is described which seems to diagnose an early presubluxation phase of glenohumeral malalignment in hemiplegic shoulders. The sign consists of a V-shaped widening of the upper part of the space between the humeral head and the glenoid cavity on anteroposterior shoulder films in the erect position. Twelve of 14 patients showing this sign went on to develop chronically painful shoulders, and four of them developed radiologically evident subluxation within several months. The sign may be helpful in diagnosing shoulder pathology following stroke at an early stage, when orthotic measures may still have preventive value.
描述了一种新的放射学征象，它似乎可诊断偏瘫肩部盂肱关节排列不齐的早期半脱位前期。该征象表现为站立位肩部前后位X线片上肱骨头与关节盂之间间隙上部呈V形增宽。出现此征象的14例患者中有12例继而发展为慢性肩部疼痛，其中4例在数月内出现了放射学上明显的半脱位。当采取矫形措施仍可能具有预防价值时，该征象可能有助于早期诊断中风后的肩部病变。
