Lumbar spinal stenosis and lower extremity arthroplasty

Area of Science:

• Orthopedics
• Neurosurgery
• Geriatric Medicine

Background:

• Elderly patients frequently present with both acquired lumbar spinal stenosis and degenerative joint disease of the lower extremity.
• These conditions can manifest concurrently or sequentially, impacting patient mobility and quality of life.

Purpose of the Study:

• To investigate the relationship between lower extremity degenerative joint disease and acquired lumbar spinal stenosis in elderly patients.
• To analyze the timing of symptom presentation and the need for surgical intervention in patients with both conditions.

Main Methods:

• Retrospective review of 14 patients diagnosed with both lower extremity degenerative disease and acquired lumbar spinal stenosis.
• Categorization of patients into concomitant (simultaneous) and sequential (post-arthroplasty) symptom presentation groups.
• Comparison of preoperative hip and knee scores between the two groups.

Main Results:

• Five patients presented with concomitant symptoms, while nine presented with spinal stenosis symptoms after joint arthroplasty.
• No significant differences in preoperative hip and knee scores were found between the concomitant and sequential groups.
• Seven of the nine patients in the sequential group required subsequent spinal decompression surgery.

Conclusions:

• Lumbar spinal stenosis should be considered in elderly patients with persistent neurogenic claudication after joint arthroplasty.
• Preoperative counseling regarding the potential need for subsequent spinal surgery is crucial for patients undergoing joint replacement.
