Study design: A case report.
Objective: To report the first myotonic dystrophy case in which cervical kyphosis had been surgically corrected.
Summary of background data: Myotonic dystrophy is an autosomal dominant disease that shows myotonia, progressive muscle atrophy, and other various symptoms. Instability of the neck is expected to cause disorders of the cervical spine; however, there are no detailed reports on deformity of cervical spine associated with this disease.
Methods: A 43-year-old man with cervical kyphosis due to myotonic dystrophy had undergone an occiput-T2 fusion with autogenous iliac bone using spinal instrumentation.
Results: The activity of daily life of the patient had improved markedly, and the good results continued to be preserved for 5 years. There were not any major perioperative complications.
Conclusions: Surgical correction of cervical spine is not necessarily a contraindication for myotonic dystrophy.
