Summary
C5 palsy, a complication following cervical spine surgery, is often caused by surgical instrument injury to the cervical spinal cord's anterior horn. Reducing instrument compression can mitigate this risk.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Neurology
Background:
- C5 palsy is a recognized complication after cervical spine surgery.
- Existing theories, including nerve root tethering and spinal cord injury, have limitations in fully explaining C5 palsy.
- The condition primarily affects motor function in the upper limb muscles.
Purpose of the Study:
- To review the definition and explore potential etiologies of C5 palsy.
- To analyze the causes of C5 palsy based on extensive literature review and clinical experience.
Main Methods:
- Comprehensive literature review of C5 palsy.
- Analysis of clinical practice experience and research findings.
Main Results:
- Two primary theories (nerve root tether and spinal cord injury) exist but are insufficient.
- A proposed etiology is instrumental injury to the anterior horn of the cervical spinal cord during anterior cervical decompression.
- Posterior approach C5 palsy may relate to nerve root tethering from spinal cord drift post-decompression.
Conclusions:
- C5 palsy following cervical decompression surgery is primarily attributed to instrumental injury to the cervical spinal cord.
- Recommendations include minimizing spinal cord compression by surgical instruments to reduce complication risk.
