The authors describe a patient with congenital spondylolysis of the axis that caused myelopathy. The patient was a 57-year-old woman with long-standing gait disturbance. Plain cervical radiography revealed a radiolucent defect across the pedicle of the axis. Magnetic resonance imaging of the cervical spine in the neutral, flexion, and extension neck positions as well as a computerized tomography myelography in the neutral neck position failed to demonstrate any spinal cord compression. When she rotated her neck, however, the spinal cord was caught between the hypertrophic anterior arch of the atlas and posterior part of the slipped pedicle of the axis on the contralateral side. The spinal cord was transformed into a pear shape. Mechanical injury to the spinal cord seemed to explain her neurological presentation. This is, to the authors' knowledge, the 15th case of axial spondylolysis and the sixth case of spinal cord involvement of the cervical spondylolysis. No cases involving myelopathy secondary to such a unique mechanism have been reported previously in the literature.<\/jats:p>","DOI":"10.3171\/spi.2003.98.1.0084","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:59:32Z","timestamp":1241711972000},"page":"84-86","source":"Crossref","is-referenced-by-count":5,"title":["Congenital spondylolysis of the axis with associated myelopathy"],"prefix":"10.3171","volume":"98","author":[{"given":"Motoo","family":"Kubota","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naokatsu","family":"Saeki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Yamaura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiaki","family":"Yamamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuko","family":"Nemoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshio","family":"Fukutake","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Skeletal Radiol","doi-asserted-by":"publisher","first-page":"79","DOI":"10.1007\/BF00363958","article-title":"Spondylolysis and spondylolisthesis of the cervical spine.","volume":"3","author":"Charlton","year":"1978"},{"key":"b2","series-title":"Pediatr Radiol","doi-asserted-by":"publisher","first-page":"535","DOI":"10.1007\/BF02389566","article-title":"Primary spondylosis of the axis vertebra (C2) in three children, including one with pyknodysostosis.","volume":"19","author":"Currarino","year":"1989"},{"key":"b3","series-title":"J Bone Joint Surg Br","first-page":"526","article-title":"Defects of the pedicle and spondylolisthesis of the second cervical vertebra.","volume":"63","author":"Fardon","year":"1981"},{"key":"b4","series-title":"AJR","doi-asserted-by":"publisher","first-page":"751","DOI":"10.2214\/ajr.154.4.2107670","article-title":"Cervical spondylolysis: imaging findings in 12 patients.","volume":"154","author":"Forsberg","year":"1990"},{"key":"b5","series-title":"AJR","doi-asserted-by":"publisher","first-page":"682","DOI":"10.2214\/ajr.128.4.682","article-title":"Spondylolisthesis of the axis vertebra.","volume":"128","author":"Gehweiler","year":"1977"},{"key":"b6","series-title":"Neuroradiology","doi-asserted-by":"publisher","first-page":"159","DOI":"10.1007\/BF00337553","article-title":"Congenital spondylolysis of cervical vertebrae with spondylolisthesis and frontal narrowing of the spinal canal.","volume":"11","author":"Guillaume","year":"1976"},{"key":"b7","series-title":"Spine","doi-asserted-by":"publisher","first-page":"901","DOI":"10.1097\/00007632-198311000-00015","article-title":"Spondylolysis of the axis.
