AbstractThe incidence of cervical spondylosis in the elderly is increasing with the higher proportion of elderly individuals among the Japanese population. The present study retrospectively analyzed the clinical and radiological features of this clinical entity in 107 patients with cervical spondylosis aged 70 years or older surgically treated between 1995 and 2005. The patients were divided into Group 1 (n = 60) aged between 70 and 74 years, and Group 2 (n = 47) 75 years or older. Patients with localized compression within 2 levels responsible for the neurological symptoms underwent anterior fusion, and patients with a narrow spinal canal were treated by laminoplasty. The pre- and postoperative neurological status (Neurosurgical Cervical Spine Scale) and postoperative complications were compared. More patients in Group 2 required laminoplasty but most patients underwent single-level anterior fusion. There was no statistically significant difference in the surgical results. Group 2 had a much higher ratio of anterior fusion at the C3-4 level. Many of the aged patients had multiple risk factors. Surgical decompression for cervical spondylosis is beneficial even in elderly patients. Single-level anterior fusion to treat the lesion most responsible for the symptoms is the least invasive choice. Elderly patients tend to present with multiple risk factors so require careful perioperative management.
