Is spinal stenosis better treated surgically or nonsurgically?

Area of Science:

• Neurosurgery
• Orthopedics
• Rehabilitation Medicine

Background:

• Lumbar spinal stenosis (LSS) significantly impacts patient disability.
• Optimal treatment strategy (surgical vs. nonsurgical) for LSS remains a key clinical question.
• Understanding patient outcomes and expectations is vital for informed decision-making.

Purpose of the Study:

• To compare surgical versus nonsurgical treatment for lumbar spinal stenosis.
• To assess patient-reported outcomes and functional improvements.
• To determine the proportion of patients experiencing improvement, worsening, or stability over time.

Main Methods:

• Prospective, non-randomized cohort study of 125 consecutive patients with LSS.
• Patients were divided into surgical (decompression only, decompression with fusion) and nonsurgical groups.
• Outcomes assessed using the Roland-Morris questionnaire at 2-year follow-up.

Main Results:

• Surgical groups (decompression only: 6.9, decompression with fusion: 6.1) showed greater average improvement in Roland-Morris scores than the nonsurgical group (1.2).
• Surgical patients reported higher rates of improvement (63.3% and 61.5%) compared to nonsurgical patients (25.0%).
• A majority of nonsurgical patients experienced persistent symptoms; surgical patients often had residual symptoms.

Conclusions:

• Surgical intervention for lumbar spinal stenosis leads to better functional outcomes compared to nonsurgical management.
• While surgery improves outcomes for most patients, realistic expectations regarding residual symptoms are essential.
• Nonsurgical management is associated with a higher likelihood of persistent symptoms in LSS patients.
