A Case Study and Reassessment of Pathophysiology: C5 Nerve Root Palsy Following Surgical Correction of Severe Congenital Cervicothoracic Scoliosis
To present a rare case of C5 nerve root palsy following corrective surgery for severe congenital cervicothoracic scoliosis and explore its unique pathogenesis and treatment strategy.
Key Findings:
C5 nerve root palsy developed postoperatively on day 7 with decreased left deltoid strength.
CT imaging excluded direct implant impingement and laminectomy, ruling out classic posterior cord drift.
Dynamic foraminal stenosis due to excessive traction through the C5 pedicle screw was identified as the mechanism for C5 palsy, highlighting the significance of imaging studies.
Interpretation:
Iatrogenic alteration of foraminal geometry during cervical deformity surgeries can lead to C5 nerve root palsy, underscoring the need for careful surgical technique and awareness of this novel mechanism.
Limitations:
Single case report limits generalizability of findings.
Lack of long-term follow-up data on neurological recovery.
Absence of comparative cases to further assess the findings.
Conclusion:
Surgeons should avoid overtightening screws during rod reduction to prevent C5 palsy; conservative treatment typically results in favorable outcomes, emphasizing the importance of surgical technique.
