Modified French door laminoplasty using autologous spinous process as interlaminar spacer

摘要

Sir, Laminoplasty is one surgical option to treat multilevel cervical spondylotic myelopathy, especially when associated with ossified posterior longitudinal ligament (OPLL) and spinal canal stenosis. Posterior approaches to decompress multilevel cervical spinal cord compression include laminectomy, laminectomy with fusion, and laminoplasty. Laminectomy safely brings adequate decompression of the cervical spinal cord; nevertheless, it can have the adverse outcomes of epidural scar formation (post-laminectomy membrane) after cervical laminectomy and of post-laminectomy kyphosis secondary to iatrogenic destabilization of the cervical spine. Laminoplasty allows the spinal cord and the neuro-foramen to be decompressed without directly removing anterior pathology. By preserving the dorsal elements of the spine, laminoplasty preserves spine stability and alignment and decreases the risk of post-laminectomy kyphosis and instability.
