Risk factors for C₅ palsy following the posterior spinal process-splitting laminoplasty for cervical ossification of the posterior longitudinal ligament: a case control study.

ABSTRACT:

Background

Postoperative C₅ palsy is a common complication of laminoplasty for cervical ossification of the posterior longitudinal ligament (C-OPLL), although there are several hypotheses regarding its etiology, the exact pathomechanism for this undesirable event remain unclear. The aim of this study was to review clinical and imaging findings in patients with C₅ palsy and to propose potential risk factors for this complication.

Methods

A total of 220 consecutive patients who had undergone posterior spinal process-splitting laminoplasty (pSPSL) for C-OPLL between January 2018 and December 2019 were included in this study. Postoperative C₅ palsy was defined as deltoid muscle weakness of a grade ≤3 in manual muscle test (MMT). These patients we
