Simple Explanation

Foot drop is a condition where it is difficult to lift the front part of the foot due to muscle weakness or paralysis. This is often caused by nerve damage in the leg or spine. This case report describes a rare instance where a patient experienced bilateral foot drop (both feet) due to an infection in the spine (spondylitis) at the T12 vertebra, which occurred after a vertebroplasty procedure. The patient underwent surgery to relieve the pressure on the spinal cord and stabilize the spine. Following the surgery, the patient's leg strength improved, and they were able to walk without assistance.

Key Findings

  • 1
    Bilateral foot drop can be a rare complication of T12 infectious spondylitis following vertebroplasty.
  • 2
    Lesions at the thoracolumbar junction can cause atypical neurological symptoms, including bilateral foot drop, due to the complex anatomy of the spinal cord and nerve roots in this region.
  • 3
    Surgical decompression and reconstruction can lead to significant improvement in muscle strength and mobility in patients with bilateral foot drop caused by spinal cord compression.

Research Summary

This case report describes a 69-year-old male who developed bilateral foot drop due to T12 infectious spondylitis after undergoing vertebroplasty. The patient presented with leg pain, paralysis, and upper motor neuron signs. Radiological findings revealed compression of the conus medullaris due to the spondylitis. Electromyography indicated a bilateral L5 root lesion and conus medullaris lesion. The patient underwent surgical decompression and reconstruction. Postoperatively, the patient showed significant improvement in muscle strength and was able to walk without a cane. The case highlights the importance of considering thoracolumbar lesions as a cause of atypical neurological symptoms like bilateral foot drop.

Practical Implications

Diagnostic Awareness

Clinicians should consider infectious spondylitis at the thoracolumbar junction in patients presenting with atypical neurological symptoms such as bilateral foot drop, especially after vertebroplasty.

Surgical Intervention

Surgical decompression and reconstruction can be an effective treatment option for patients with bilateral foot drop caused by spinal cord compression due to infectious spondylitis.

Anatomical Understanding

A thorough understanding of the conus medullaris and nerve root anatomy at the T12-L1 level is crucial for diagnosing and treating patients with atypical neurological symptoms resulting from lesions in this region.

Study Limitations

  • 1
    Single case report limits generalizability.
  • 2
    Causative pathogen of spondylitis was not identified.
  • 3
    Long-term follow-up data is not available.
