Surgical Outcomes for Degenerative Cervical Myelopathy in Older Adults

Overview

This study compared surgical outcomes for degenerative cervical myelopathy (DCM) between patients aged ≥70 years and those aged 50–70 years using data from the Norwegian Registry for Spine Surgery. Findings indicate that while elderly patients experience meaningful improvements post-surgery, they have a higher risk of complications compared to younger patients.

Background

Degenerative cervical myelopathy is the leading cause of spinal cord impairment, presenting with symptoms such as gait disturbances, limb numbness, and autonomic dysfunction. Diagnosis is often delayed due to subtle initial symptoms, but decompressive surgery can halt progression and improve function. However, surgery carries risks, especially in older adults, and the impact of age on surgical outcomes remains unclear. This study aimed to evaluate the effectiveness and safety of surgery in patients aged ≥70 years compared to those aged 50–70 years.

Data Highlights

Key Findings

• Both age groups showed significant functional improvement after decompressive surgery for DCM.
• Patients aged ≥70 years had less improvement in Neck Disability Index and European Myelopathy Score compared to those aged 50–70 years.
• Quality of life measured by EQ-5D improved in both cohorts post-surgery.
• Older patients experienced a higher rate of perioperative and postoperative complications within 3 months.
• Complete symptom resolution after surgery is unlikely in all age groups.
• Age is a predictor of less favorable surgical outcomes and increased risk of complications.

Clinical Implications

Clinicians should consider that decompressive surgery for DCM in elderly patients can provide meaningful improvements in function and quality of life, but these patients have a higher risk of complications. Careful patient selection and counseling regarding realistic expectations and potential risks are essential when managing older adults with DCM. Early diagnosis and referral for MRI remain critical to optimize surgical outcomes.

Conclusion

Surgery for degenerative cervical myelopathy in patients aged ≥70 years is effective but yields less improvement and higher complication rates compared to younger patients. These findings support individualized surgical decision-making in the elderly population.
