Traumatic cervical spinal cord injury after cervical laminoplasty for ossification of posterior longitudinal ligament: a case series.

All of the five traumatic CSCI participants had a history of previous cervical laminoplasty for C-OPLL. Cervical laminoplasty for C-OPLL might lead to cervical spine with rigidity and ankylosing due to developing OPLL and bony facet and laminar fusion, and might have a risk for traumatic CSCI.
