I.はじめに
頸部椎間板障害に対して頸椎前方固定術は広く行われている手術法であるが,Cloward法4),Smith-Robinson法11,12),Bailey法2)に代表される頸椎前方固定術では,一般的には,腸骨より採取した骨片が移植骨として使用されているため,腸骨採取に伴う合併症14)は避けられない.今回,われわれは,腸骨採取に伴う合併症を避けるため,新しい試みとして,頸椎椎体より採取した自家骨を移植骨として用いた頸椎前方固定術を行い,良好な手術結果を得たので報告する.本報告では,本法による短期手術成績を述べると共に,手術手技を紹介する.
Since April, 1990, the authors have been reporting a surgical technique for anterior cervical fusion utilizing autogenous bone graft from the cervical vertebrae. This series included 53 patients (40 males and 13 females). The age ranged from 24 to 72 years with a mean of 49 years. There were 42 cases of cervical disc disease, and 11 cases of cervical disc disease with ossification of the posterior longitudinal ligament (OPLL). The patient was out of bed within two days and treated in a soft collar for 3 months. In all patients, the symptoms im-proved postoperatively. Postoperative X-ray showed slight anterior angulation deformity in 3 out of 53 cases (6%). The advantages of our surgical technique are as follows: 1) There are no problems related to the iliac donor site 2) The removal of posterior spur and localized OPLL is safely and easily performed.
