Abstract Discogenic back pain is multifactorial; hence, physicians often struggle to identify the underlying source of pain. As a result, discogenic hard treat—even more so when clinical treatment strategies are questionable efficacy. Based on broad literature review, our aim was define into series specific and interacting pathologies, highlight need develop novel approaches for this challenging unmet need. involves degenerative changes intervertebral disc, including structural defects that...
Retrospective study of registry data.Aging society and recent advances in surgical techniques general anesthesia have increased the demand for spinal surgery elderly patients. Many complications been described patients, but a multicenter perioperative patients aged 80 years or older has not reported. Therefore, goal was to analyze associated with spine cervical, thoracic, lumbar lesions.A performed who underwent 262 surgeries at 35 facilities. The frequency severity were examined...
In Brief Study Design. A retrospective, radiographical study. Objective. To evaluate short-term radiological changes in sagittal alignment after lumbar decompression without fusion for canal stenosis. Summary of Background Data. Although the importance global balance is underscored recently, little known about decompression. Methods. We retrospectively reviewed 88 patients who underwent at a single institution between November 2008 and May 2013, with minimum follow-up 5 months. Standing...
Retrospective database analysis.Spine surgeries in elderly patients have increased recent years due to aging of society and advances surgical techniques, postoperative complications become more a concern. Postoperative delirium is common complication that impairs recovery increases morbidity mortality. The objective the study was analyze associated with spine surgery aged 80 or older cervical, thoracic, lumbar lesions.A retrospective multicenter performed 262 age who underwent at 35...
This study compared patient characteristics, clinical outcomes, and antibiotic durations between patients undergoing posterior fixation for gram-negative rods (GNR) or gram-positive cocci (GPC) thoracolumbar pyogenic spondylitis. In this multicenter retrospective cohort study, 53 who underwent minimally invasive spondylitis were categorized into a GPC GNR group based on the identified causative organisms. Patient surgical postoperative infection control two groups to identify factors...
This study aimed to determine the relationship between preoperative fatty infiltration of lower extremity muscles and walking speed at 2 weeks after total hip arthroplasty (THA). was a single-institution retrospective cohort study. Participants in this were patients undergoing primary THA. Fatty each muscle (bilateral psoas major, gluteus maximus, medius, minimus, quadriceps, triceps surae) assessed using non-contrast X-ray computed tomography images obtained during detailed examination. The...
Loosening of screws is a common problem in orthopedic and maxillofacial surgery. Modifying the implant surface to improve mechanical strength has been tried reported. We developed coated with fibroblast growth factor-2 (FGF-2)−apatite composite layers. then showed, percutaneous external fixation model, that this layer had ability hold release FGF-2 slowly, thereby reducing risk pin tract infection fixation. The objective current study was clarify effect FGF-2−apatite layers on titanium bone...
Context: The hybrid assistive limb (HAL) is a wearable robot suit that assists in voluntary control of knee and hip joint motion by detecting bioelectric signals on the surface skin with high sensitivity. HAL has been reported to be effective for functional recovery motor impairments. However, few reports have revealed utility patients who undergone surgery thoracic ossification posterior longitudinal ligament (thoracic OPLL). Herein, we present postoperative OPLL patient showed remarkable...
Abstract This prospective multicenter study, established by the Japanese Ministry of Health, Labour and Welfare involving 27 institutions, aimed to compare postoperative outcomes between laminoplasty (LM) posterior fusion (PF) for cervical ossification longitudinal ligament (OPLL), in order address controversy surrounding role instrumented cases surgical decompression OPLL. 478 patients were considered participation study; from among them, 189 (137 52 with LM PF, respectively) included...
Background: The incidence of low back pain (LBP) is high in patients with hip osteoarthritis (OA). Evidence from previous studies suggests that lumbar alignments and range motion (ROM) are important etiological factors for LBP. However, no stu
A prospective multicenter study.To evaluate and compare the surgical outcomes after open-door (OD) double-door (DD) laminoplasties in subjects with cervical ossification of posterior longitudinal ligament (OPLL).Although previous studies compared clinical results OD DD laminoplasties, they were performed at a single institution relatively small sample size targeting mixed pathologies, including spondylotic myelopathy.This study was by Japanese Multicenter Research Organization for...
This article was updated on October 19, 2022, because of previous errors, which were discovered after the preliminary version posted online. On page 1787, in legend for Figure 2, sentence that had read "The vertebral collapse rate (in %) defined as 1 - (A/P) × 100, and instability difference between loaded non-loaded images." now reads (1 [A/P]) 1788, section entitled "Data Collection," (anterior wall height/posterior height) images 9 ."

The usefulness of minimally invasive posterior fixation without debridement and autogenous bone grafting remains unknown. This multicenter case series aimed to determine the clinical outcomes limitations this method for thoracolumbar pyogenic spondylitis. Patients with spondylitis treated alone were retrospectively evaluated at nine affiliated hospitals since April 2016. study included 31 patients (23 men 8 women; mean age, 73.3 years). course requirement additional anterior surgery...
Context: The hybrid assistive limb (HAL) (the wearable robot) can assist kinesis during voluntary control of hip and knee joint motion by detecting the wearer's bioelectric signals on surface their skin. purpose this study was to report walking ability following robot treatment in a patient with chronic myelopathy after surgery for cervical ossification posterior longitudinal ligament (OPLL). Findings: 66-year-old woman OPLL who able ambulate independently aid bilateral crutches. received...
