Abstract | OBJECTIVE: METHODS: The series included 49 patients with OPLL. Characteristics of preoperative and postoperative x-ray, computed tomography, and magnetic resonance images were compared between the patients with and those without C5 root palsies. RESULTS: Postoperative C5 root palsies occurred in 9 patients 6 to 64 hours postoperatively. They tended to have increased cervical lordosis and severe OPLL. However, there was no significant positive correlation with an increase in T2-weighted hyperintense foci on magnetic resonance studies. CONCLUSIONS: The tethering effect on the root seemed to be the main pathogenic mechanism of C5 root palsies in this study.
