Abstract
X-ray findings of the shoulder were analyzed in 55 hemiplegic patients, especially about the relationship to clinical subluxation of the shoulder joint. Subjects were 55 hemiplegic patients whose average age was 49.7 and the interval from the onset was within 1 year. In A-P view of bilateral shoulder joints, α; the angle between spine and glenoid, and G; the interval between medial humeral neck and lower edge of glenoid were measured. AHI: Acromio-Humeral Interval was also measured in each side A-P view. Bone atrophy and osteoarthritic change in affected shoulder were evaluated, the relation between clinical subluxation and x-ray findings, Br. stage, and the interval from the onset were examined. In affected side, as a result, the angle of glenoid to the spine was more steep, and humeral head dislocated more downward. Bone atrophy was seen in almost cases, and osteoarthritic change was observed in about 60% of the subjects. In the group that had clinical subluxation, AHI and G was significantly increased and there was close relationship, α was not significantly increased in this group. Osteoarthritic change was seen more frequently in the group that did not have clinical subluxation. In Br. stage. II to VI, the stage was lower, the incidence of subluxation was higher. However, within 1 year, the incidence of subluxation was not relate to the interval from the onset.
