若年性の頸椎部flexion myelopathyの外科的治療

Surgical Outcome of Cervical Flexion Myelopathy in Young Adults

　われわれは，5例の若年性の頸椎部flexion myelopathy症例を経験し，全例に外科的治療を行った。5例のうち3例に2椎体切除3椎間前方固定術，2例に5椎弓後方固定術を施行し，術後の症状の変化を追跡した。術後3カ月以内に4例で上肢の麻痺の改善がみられ，残り1例に知覚障害の改善が認められた。すなわち全例に症状の進行停止および改善が認められ，外科的治療は若年性のflexion myelopathyに対する有力な治療法と考えられた。

We encountered five young male patients with cervical flexion myelopathy, and treated them all surgically. Symptoms were first noted at 15 to 18 years of age (mean : 16.6 years), and their ages at the time of admission to our hospital, ranged from 19 to 25 years old (mean : 20.8 years). Anterior decompression and fusion of the cervical spine with long bone graft following resection of two vertebrae was performed in three cases. The other two patients were treated by posterior fusion of five laminas (C3-C7) using Rogers' method.
