Laminoplasty has gained acceptance as an effective surgical option. Over the last two decades many laminoplasty techniques have been developed. Our specific aim is to distinguish the biomechanical differences, if any, of the FDL and ODL techniques. There have been numerous clinical follow-up studies in the literature specifying differing degrees of cervical laminoplasty involvement. Our goal is to determine the degree of instability as a fuction of level involvement.
Bone exhibits an astounding ability to regenerate in response to a gradual distractive force.
This principle has been utilized in the clinical setting to treat various skeletal deformities. Whether varying these parameters influences differentiation by way of callus stresses and strains remains unclear. Current remodeling theories that relate the mechanical environment to tissue differentiation are unable to elucidate the mechanism of this time-dependent relationship between distraction and tissue regeneration. We postulate that this is because viscoelastic behaviors, such as fluid flow, are not incorporated into the existing engineering models. Increasing the distraction rhythm, which in the extreme becomes continuous distraction, is associated with enhanced mineralization in the regenerate.
