Foot drop caused by single-level disc protrusion between T10 and L1

Area of Science:

• Neurosurgery
• Spinal Surgery
• Neurology

Background:

• Foot drop is rarely associated with single-level disc protrusion between T10 and L1.
• Existing literature primarily reports cases involving T12-L1 disc protrusions.

Purpose of the Study:

• To describe surgical outcomes for foot drop resulting from single-level disc protrusion in the T10-L1 region.
• To investigate the characteristics of foot drop and associated neurological findings in this patient cohort.

Main Methods:

• Retrospective analysis of 25 patients with T10-L1 single-level disc protrusion and foot drop.
• Surgical intervention involved circumferential decompression with fixation.
• Assessment included neurological status, muscle strength, and imaging pre- and post-operatively.

Main Results:

• All patients presented with both lower and upper motor neuron signs.
• Mean muscle strength recovery rate was 95% post-surgery.
• Significant improvements were observed in Japanese Orthopaedic Association scores and dural sac cross-sectional area.

Conclusions:

• Single-level disc protrusion between T10 and L1 can cause foot drop, often with upper motor neuron involvement.
• Surgical decompression and fixation appear effective for treating this condition.
• The presentation of pathological reflexes may vary based on the specific level of protrusion.
