関節突起間脊椎分離症の保存的療法の遠隔成績に就て

抄録

In a series of 50 patients of spondylolysis with low back pain, the results of conservative treatments were investigated.
Fifty percent of the series were relieved from pain, and the other remained unimproved.
The abnormal mobility of separated vertebra was detected in 29 patients, but not in remaining 21 patients.
The effectiveness of the conservative treatment was established in those who were not engaged in labour and belonged to the latter group; not only any improvement was obtained in labourers belonged to the former group, but also increased the pain gradually.
