Multilevel laminotomy entails the risk of instability of the spine. In
this paper, we propose an application of the open-door laminoplasty t
echnique in pediatric spinal neurosurgery. A standard laminotomy is pe
rformed at one side while a groove is drilled out at the other side to
preserve the internal periosteum of the lamina. This allows a rolling
elevation without complete separation of the laminae. The advantages
of such a method are discussed.
