Outcome Evaluation of Modified Uninstrumented Open-door Cervical Laminoplasty for Ossified Posterior Longitudinal Ligament with Cervical Myelopathy.

Study Design: This was a retrospective study.

Purpose: To evaluate the short term outcomes of a novel self-developed technique of performing uninstrumented open-door cervical laminoplasty (ODCL) in patients with cervical myelopathy secondary to ossified posterior longitudinal ligament (OPLL).

Review Of Literature: Published literature on cervical laminoplasties largely focuses on the outcomes of instrumented variants.
