Evolution of Cervical Laminoplasty

Laminoplasty was first performed by hinging the bone open and holding it in place with a piece of bone taken from another location. This piece of bone would be held in place by a small metal plate bent to the correct position by the surgeon. The goal with this would be for the bone that was holding the gap open to heal across. However with advancements in technology and understanding of outcomes there has been the development of special plates that hold the bone open at the ideal angle to allow for increased room for the spinal cord.

Additionally, it has been determined that patients do extremely well with this procedure even if there is not a bony bridge holding the gap open, as the plate provides sufficient strength. Additionally, there is decreased operative time, faster recovery as the patient does not have to wait for the bone bridge to heal, and mitigate the risk of morbidity at another operative site for bone harvest.

Technology Spotlight

DePuy Synthes MOUNTAINEER™ Laminoplasty Spine System

DePuy Synthes MOUNTAINEER™ Laminoplasty Spine System has designed the ideal plate for the laminoplasty procedure. The system has been designed for ease of surgeon use, with multiple configurations of plates to better match patient anatomy, and allows for increased stability with the ability to supplement with redundant fixation and bony augmentation. The procedure is done through a posterior midline approach to the cervical spine. This implant allows the maintenance of neck motion without the risk of instability while effectively relieving pressure on the spine.
