Post-operative nerve injuries after cervical spine surgery

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Neurology

Background:

• Cervical spine surgery can lead to rare but significant post-operative nerve injuries.
• Common injuries include C5 nerve palsy, Parsonage-Turner syndrome, C8-T1 palsies, and Horner's syndrome.
• Understanding these risks is crucial for prevention and management.

Purpose of the Study:

• To review the most common nerve injuries following cervical spine procedures.
• To identify risk factors, clinical presentations, and management strategies for each type of nerve injury.
• To emphasize the importance of early diagnosis and appropriate treatment.

Main Methods:

• Literature review of post-operative nerve injuries after cervical spine surgery.
• Analysis of risk factors, clinical manifestations, and treatment approaches for C5 palsy, Parsonage-Turner syndrome, C8-T1 palsies, and Horner's syndrome.
• Discussion of preventative surgical techniques and diagnostic evaluations.

Main Results:

• C5 nerve palsy presents as deltoid/biceps weakness, associated with male gender, OPLL, and posterior approaches.
• Parsonage-Turner syndrome involves severe pain followed by brachial plexus deficits.
• C8-T1 palsies cause hand weakness and sensory loss; Horner's syndrome results from sympathetic chain injury.

Conclusions:

• Early recognition and understanding of risk factors for C5 palsy, Parsonage-Turner syndrome, C8-T1 palsies, and Horner's syndrome are vital.
• Conservative treatment is often employed, but evaluation for residual compression is essential.
• Specific surgical considerations can minimize the risk of these nerve injuries.
