Novel Three‐Holed Titanium Plate Fixation during Open Door Laminoplasty for Cervical Spondylotic Myelopathy: Comparison with Conventional Titanium Plate

Abstract

Objective: For reconstructing the posterior cervical muscular-ligament complex, attachment points and various modified techniques were designed and applied in clinical practice. This study investigated the clinical and radiographic outcomes of open door laminoplasty with modified centerpiece mini-plate fixation and extensor attachment point reconstruction in the treatment of cervical spondylotic myelopathy (CSM).Methods: Sixty-nine patients with CSM who underwent C3-C7 open door laminoplasty at our hospital from January 2016 to May 2018 were divided into two groups: 37 and 32 patients underwent laminoplasty with modified and conventional centerpiece titanium plate fixation (MPF and CPF groups), respectively. Changes in cervical spinal angle (CSA), cervical range of motion (ROM), posterior cervical muscle atrophy, neurological function (Japanese Orthopaedic Association [JOA] score), Neck Disability Index (NDI), and axial symptom severity were compared between the two groups.

Ipsilateral Fixation and Reconstruction of the Cervical Spine after Resection of a Dumbbell Tumor Via a Unilateral Posterior Approach: A Case Report and Biomechanical Study

“…During removal of a dumbbell tumor via a unilateral posterior approach, the damage to the posterior stabilizing structures, which include the lamina, facet joints, and posterior ligaments, 15 has been shown to increase spinal instability, accelerate disc degeneration and progression to adjacent segment disease (ASD). In addition, surgical damage to cervical muscle attachment points can weaken the cervical stability 16 . Therefore, internal fixation treatment should be considered to provide additional support for the stability of the affected segment.…”

“…In addition, surgical damage to cervical muscle attachment points can weaken the cervical stability. 16 Therefore, internal fixation treatment should be considered to provide additional support for the stability of the affected segment. However, it is unclear if unilateral pedicle screw and contralateral lamina screw fixation combined with lateral mass reconstruction (UPS + CLS + LM) provides sufficient stability as compared to pedicle screw fixation and transarticular screw fixation after removal of a dumbbell tumor via a unilateral posterior approach.…”
