　1956年Wolf^15）により初めてcervical spondylosisにおける脊髄症状発現には，脊椎管腔前後径の大きさが重要な因子として関与することが指摘され，1964年Hinck^3）はdevelopmental stenosis of the cervical spinal canalの概念を提唱した．最近われわれは，50歳男性で，鼻根部陥凹，三尖手，四肢短小等の特異な体型を有し，その脊髄症状発現の主要因が著明な頸椎脊椎管腔前後径の狭小であると老えられたdevelopmental stenosis ofthe cervical spinal canalの1症例を経験したので，文献的考察を加えてここに報告する．

A case of developmental stenosis of the cervical spinal canal with the flat nasal bridge, the trident-shaped hands and the short limbs was reported.

The patient was 50-year-old man, who noticed gait disturbance and weakness of the upper extremities eight years prior to admission and three years later complained of difficulty in urinary and bowel control, and sensory disturbance in the arms and legs. These symptoms became worse progressively and he was admitted to Hokkaido University Hospital on June 20, 1978.
