Abstract

Laminoplasty is a technique often used in spine surgery as a way of restoring a patient's normal anatomy and posterior tension band (PTB). In pediatric patients, this is an important consideration given their intrinsic relative ligamentous laxity and significant potential for future growth. Conventional laminoplasty re-approximates the bone removed at each vertebral segment, relying on the lamina to heal through osteogenesis and the soft tissue of the PTB to heal from a sharp division. Ligamentous healing of the PTB constitutes the formation of a scar that is biologically and biomechanically inferior to the tissue it has replaced. Herein, the authors present two pediatric cases in which the novel technique of transverse split laminoplasty was used to approach intradural pathology and subsequently reconstruct the spine, while maximizing preservation of the PTB, with excellent post-surgical outcomes.
