Clinical Scorecard: Evaluation of Surgical Interventions for Degenerative Cervical Myelopathy in Older Adults: Insights from a Nationwide Registry and Patient-Reported Outcomes

At a Glance

Key Highlights

• DCM is the most common cause of spinal cord impairment with a broad symptom spectrum and often delayed diagnosis.
• Decompressive surgery can halt progression and improve function, but complete symptom resolution is unlikely and surgical risks are significant.
• Elderly patients (≥ 70 years) may have less favorable outcomes and higher complication rates compared to younger patients (50–70 years), though data remain limited.

Guideline-Based Recommendations

Diagnosis

• Clinicians should maintain high suspicion for DCM in patients with relevant symptoms and refer for MRI to confirm diagnosis.

Management

• Selected patients with clinical and radiographic evidence of DCM should be considered for decompressive surgery to arrest progression and improve neurological function.
• Surgical approach and instrumentation should be individualized based on surgeon discretion and patient factors.

Monitoring & Follow-up

• Use validated outcome measures such as Neck Disability Index (NDI), European Myelopathy Score (EMS), EQ-5D, and Numeric Rating Scales (NRS) for pain to assess pre- and postoperative status.
• Monitor for perioperative complications within 3 months post-surgery through both surgeon and patient reports.

Risks

• Approximately one in three patients report adverse events within 3 months post-surgery.
• Elderly patients may have increased risk of complications and less improvement in functional outcomes.

Patient & Prescribing Data

Patients aged ≥ 50 years undergoing decompressive surgery for degenerative cervical myelopathy, stratified into 50–70 years and ≥ 70 years cohorts.

Surgical decompression improves functional status and quality of life but does not typically result in complete symptom resolution; elderly patients may experience less improvement and higher complication rates.

Clinical Best Practices

• Early recognition and diagnosis of DCM with MRI referral to reduce diagnostic delay.
• Use of standardized and validated patient-reported outcome measures (NDI, EMS, EQ-5D, NRS, GPE) for comprehensive assessment.
• Individualized surgical planning considering patient age, comorbidities, and severity of myelopathy.
• Close postoperative monitoring for complications within the first 3 months.
• Informed consent discussions should include realistic expectations about symptom improvement and potential risks, especially in elderly patients.
