C5 Palsy After Cervical Decompression: A 10-Year Single-Institution Study Highlighting Early Onset, High Bilaterality, and Poor Recovery

C5 palsy in this cohort showed early onset, high bilaterality, and poor recovery, suggesting multifactorial mechanisms rather than isolated root traction. Posterior approaches and foraminal stenosis appear to be important risk factors. Preventive strategies should include detailed imaging, selective foraminotomy, neuromonitoring, and refined surgical technique. Further multicenter studies are needed to clarify pathogenesis and improve outcomes.
