Can lumbar osteophyte formation cause numbness in the feet?

Generally, whether lumbar osteophyte formation causes numbness in the feet depends on the severity of the condition. Mild cases usually do not lead to foot numbness; however, if the bone spurs compress nearby nerves, numbness may occur. The detailed analysis is as follows:

When lumbar osteophyte formation is mild and does not compress surrounding nerves or blood vessels, patients typically experience only mild lower back soreness and stiffness, particularly after prolonged sitting or standing, with symptoms improving upon rest. Foot numbness does not usually occur in such cases. With adequate rest and avoiding excessive strain on the lower back, symptoms can generally be well controlled.

If lumbar osteophyte formation progresses and the bony overgrowths begin to compress the lumbar nerve roots, nerve conduction can be impaired, leading to numbness in the feet. This is often accompanied by radiating pain and weakness in the legs, and some patients may feel their legs giving way while walking. In such cases, timely adjustments to posture and appropriate rehabilitation exercises are necessary to relieve nerve compression and prevent worsening symptoms.

In daily care, it is recommended to avoid prolonged bending or sitting, and to use a mattress with moderate firmness that provides proper support for the lower back. Additionally, keeping the lower back warm and avoiding exposure to cold can help reduce flare-ups of lumbar osteophyte symptoms and maintain spinal health.
