Retrospective study of new muscle-preserving exposure techniques and their application to posterior cervical spine surgery.To describe for the spine, demonstrate how a variety surgeries varying pathologies allows preservation mobility stability.Although surgical approaches through intermuscular planes have been applied extremities anterior spinal column, our knowledge, they yet be spine.We used since 2000, applying them selective mono laminoplasty (73 patients) myelopathy, intervertebral...
Study Design. A retrospective single-center study. Objective. The aim of this study was to evaluate the compensatory mechanism cervical lordosis (CL), changes in sagittal alignment, and range motion (ROM) after muscle-preserving selective laminectomy (SL). Summary Background Data. CL increases as a for adjustment balance or horizontal gaze. However, laminoplasty invades causes kyphosis higher T1 (C7) slope patients. Methods. SL is posterior surgery selecting decompression laminae without...
Extracellularly released adenosine triphosphate (ATP) modulates sensory signaling in the spinal cord. We analyzed spatiotemporal profiles of P2X receptor-mediated neuronal and glial processing signals distribution receptor subunits rat dorsal horn. Voltage imaging cord slices revealed that extracellularly applied ATP (5-500 μM), which was degraded to acting on P1 receptors, inhibited depolarizing it also enhanced long-lasting slow depolarization, potentiated after washed out. This post-ATP...
In spine surgery, instrumentation surgery using augmented reality (AR) and navigation systems have become widespread, while decompression those applications is not so common. However, we sometimes encounter intraoperative problems such as excessive blood loss or bony resection in surgery. Therefore, a practical system needed for safer spinal Furthermore, the cost of AR has been expensive. this study, report utility applying head-mounted display (HMD) at lower to identify osteotomy area...
A retrospective study at a single academic institution.
The diaphragm is driven by phrenic motoneurons that are located in the cervical spinal cord. Although anatomical location of nucleus and function at a single cellular level have been extensively analyzed, spatiotemporal dynamics motoneuron group activity not fully elucidated. In present study, we analyzed functional structural characteristics respiratory neuron population cord voltage imaging, together with histological analysis neuronal astrocytic distribution We found spatially distinct...
Wrong-site spine surgery is an incident that could result in possible severe complications. In this present spinal surgery, the accurate level confirmed via preoperative or intraoperative radiographic marking. However, location of marking has been determined from manual palpation on landmarks body surface. As a result, deformity can make it hard to identify by palpation, thus leading misidentification level.Recently, use mixed reality gradually increasing. study, we will demonstrate...
Study Design Retrospective multicenter study. Objectives To investigate surgical outcomes following posterior decompression for cervical ossification of the longitudinal ligament (OPLL) when performed by board-certified spine (BCS) or non-BCS (NBCS) surgeons. Methods We included 203 patients with OPLL who were followed a minimum 1 year after surgery. Demographic information, medical history, and imaging findings collected. Clinical assessed preoperatively at final follow-up using Japanese...
The characteristics of cervical spondylolisthesis are not currently fully understood, because the shortage reports covering large population patients with spondylolisthesis. purpose this study was to elucidate by examining a relatively number cases.We analyzed 101 cases more than 2 mm vertebral listhesis as determined from X-ray or computed tomography (CT) images among 731 who underwent surgery at single institute. We considered C2-7 angle, range motion, and sagittal vertical axis on lateral...
Several reports have compared spinal cord tumor removal techniques but none clearly described the appropriate site and level of indication for laminectomy or laminoplasty. The approach method depends on type localization surgeon's skill. Therefore, a system that can suggest various surgical is useful surgery. mixed reality introduced in this paper an excellent procedures. Using removal, we made surgery less invasive; therefore, demonstrated its usefulness. Stereoscopic data patients with...
Study Design: This was a case-control study. Objective: The objective of this study to clarify the surgical outcomes after cervical posterior decompression in patients who smoked. Summary Background Data: Smoking is associated with poor field spinal surgery. However, impact tobacco smoking on surgery has not been fully evaluated spondylotic myelopathy. Materials and Methods: In retrospective multicenter study, 587 myelopathy were enrolled at 17 institutions Japan. Patients underwent...
Multicenter retrospective study.We aim to investigate features of cervical spondylotic myelopathy (CSM) associated with anterior spondylolisthesis (ACS) during posterior decompression surgery.A total 732 patients CSM were enrolled, who underwent surgery between July 2011 and November 2015 at 17 institutions. The ACS (group A), defined as an slippage ≥2 mm on plain radiographs, compared those without non-A). Also, the characteristics progression P), postoperative worsening or newly developed...
Study Design. A retrospective single-center study. Objective. The aim of this study was to investigate the influence K-line in neck-flexed position (flexion K-line) on surgical outcome after muscle-preserving selective laminectomy (SL) for cervical spondylotic myelopathy (CSM). Summary Background Data. Development CSM is associated with dynamic factors and alignment. flexion K-line, which reflects both alignment factors, provides an indicator posterior decompression surgery patients...
Abstract Methotrexate-associated lymphoproliferative disorder is recognized as a lymphoma that occurs following methotrexate administration. The lesion of the spine extremely rare, and only one case in lumbar has been reported so far. Here, we present methotrexate-associated thoracic 54-year-old woman with rheumatoid arthritis. formed an extra-skeletal tumor mass from lateral to vertebral body paravertebral muscle extending posterior epidural space without bone destruction. Magnetic...
As C7 slope increases, lordotic change of C2-C7 angle compensates for adjustments in cervical sagittal balance. However, ossification the posterior longitudinal ligament (OPLL) may affect compensatory mechanism spine. This study aims to evaluate impact OPLL on compensation after muscle-preserving selective laminectomy (SL).This involved 235 patients with spondylotic myelopathy (CSM) and who underwent ≥ 3 consecutive levels SL. was classified into continuous, segmental, mixed, or localized...
