“…Additionally, a restorative laminoplasty for intraspinal surgery enables surgeons to prevent postoperative bleeding and the invasion of hematoma and scar tissue and facilitates uncomplicated access for any subsequent surgeries. It has been demonstrated that the restorative laminoplasty is a versatile surgical option that is not limited by age, surgical site, or the number of affected segments [19]. There is little debate that a laminoplasty is a more practical surgical technique than a laminectomy for the treatment of intraspinal pathologies [19].…”

There is little debate that a laminoplasty is a more practical surgical technique than a laminectomy for the treatment of intraspinal pathologies [19]. In this case, a restorative laminoplasty should be a potentially valuable option; however, it has not yet gained widespread recognition or application [4,[20][21][22][23][24][25].…”

“…In addition to other factors, the widespread use of pedicle screws was another significant factor influencing the widespread adoption of restorative laminoplasties [5]. Pedicle screws are currently the most commonly utilized internal fixation devices following laminectomies [5,19]. A laminectomy using pedicle screw fixation has increasingly become the preferred method for addressing this disorder, as it can help prevent postoperative instability and deformity, particularly in cases in which long segments need to be exposed [19].…”

A novel H-shaped miniplate (HSM) was specifically designed for restorative laminoplasties to restore patients’ posterior elements after laminectomies. A validated finite element (FE) model of L2/4 was utilized to create a laminectomy model, as well as three restorative laminoplasty models based on the fixation of different miniplates after a laminectomy (the RL-HSM model, the RL-LSM model, and the RL-THM model). The biomechanical effects of motion and displacement on a laminectomy and restorative laminoplasty with three different shapes for the fixation of miniplates were compared under the same mechanical conditions. This study aimed to validate the biomechanical stability, efficacy, and feasibility of a restorative laminoplasty with the fixation of miniplates post laminectomy. The laminectomy model demonstrated the greatest increase in motion and displacement, especially in axial rotation, followed by extension, flexion, and lateral bending. The restorative laminoplasty was exceptional in preserving the motion and displacement of surgical segments when compared to the intact state. This preservation was particularly evident in lateral bending and flexion/extension, with a slight maintenance efficacy observed in axial rotation. Compared to the laminectomy model, the restorative laminoplasties with the investigated miniplates demonstrated a motion-limiting effect for all directions and resulted in excellent stability levels under axial rotation and flexion/extension. The greatest reduction in motion and displacement was observed in the RL-HSM model, followed by the RL-LSM model and then the RL-THM model. When comparing the fixation of different miniplates in restorative laminoplasties, the HSMs were found to be superior to the LSMs and THMs in maintaining postoperative stability, particularly in axial rotation. The evidence suggests that a restorative laminoplasty with the fixation of miniplates is more effective than a conventional laminectomy due to the biomechanical effects of restoring posterior elements, which helps patients regain motion and limit load displacement responses in the spine after surgery, especially in axial rotation and flexion/extension. Additionally, our evaluation in this research study could benefit from further research and provide a methodological and modeling basis for the design and optimization of restorative laminoplasties.
