The Anatomical Mechanism of C5 Palsy After Expansive Open-door Laminoplasty

Expansive open-door laminoplasty (ELAP) has been an effective and safe method with favorable outcomes for treating patients with multilevel cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) [1-6]. However, postoperative C5 nerve root palsy (C5 palsy) remains a common complication of ELAP [7, 8]. Postoperative C5 palsy is often defined as an unilateral severe weakness of the deltoid and/or the biceps brachii muscle without any deterioration of myelopathy symptoms [7-14].
