[Myelopathy and cervical spino-stenosis]

Area of Science:

• Neurology
• Orthopedic Surgery
• Traumatology

Context:

• Traumatic myelopathy of the cervical spine is a significant cause of neurological deficit.
• Sagittally narrowed vertebral canals predispose individuals to severe spinal cord injury even with minimal trauma.
• A review of 31 cases admitted between 1986-1990 identified this specific patient cohort.

Purpose:

• To analyze the clinical characteristics and treatment outcomes of patients with traumatic cervical myelopathy and a sagittally narrowed vertebral canal.
• To highlight the diagnostic challenges associated with this condition, where imaging may not reflect the severity of spinal cord damage.
• To evaluate the efficacy of non-operative versus surgical management.

Summary:

• Patients with a narrowed cervical spinal canal are vulnerable to severe spinal cord damage from minor neck trauma or hyperextension.
• Clinical presentation often shows minimal neck symptoms and subtle bony abnormalities on imaging, despite significant spinal cord injury.
• Non-operative management frequently results in poor recovery or progressive deterioration.
• Surgical intervention, specifically expansion canal laminoplasty, demonstrated potential for better outcomes.

Impact:

• This study underscores the importance of considering spinal canal stenosis in patients with unexplained neurological deficits after cervical trauma.
• It emphasizes the limitations of conventional imaging in assessing the full extent of spinal cord injury in these cases.
• The findings support surgical decompression and expansion (laminoplasty) as a potentially superior treatment option for improving neurological recovery in this high-risk group.
