X-ray Measurement of the Subacromial Space / 实用放射学杂志

ABSTRACT

Objective To explore X-ray measurement of the subacromial space and to determine the normal range of it.Methods Shoulder joints in 188 healthy adults were examined with routine X-ray on the anterior-posterior position and the anterior lateral part of acromion to the intercondylar line of humerus(h1),as well as the most lateral part of acromion to intertubercular sulcus of humeral head(h2) were measured and observed.Results The 95% reference ranges in h1,h2 were 6.4～10.4 mm and 11.0～17.6 mm,respectively.Conclusion Both h1 and h2 can correctly reflect the bony distance of subacromial space,which is of significant meaning for guiding clinical diagnosis and therapy.
