Prospective study.To examine the efficacy of teriparatide or bisphosphonate treatment to reduce pedicle screw (PS) loosening after instrumented lumbar posterolateral fusion in postmenopausal women with osteoporosis.Failure fixation caused by PSs osteoporosis is a problem spinal surgery. Oral administration intermittent injection parathyroid hormone increases bone mass and reduces risk osteoporotic vertebral fractures. Although these treatments may be factor improving quality, clinical study...
A retrospective multicenter survey.To investigate the perioperative complications of oblique lateral interbody fusion (OLIF) surgery.OLIF has been widely performed to achieve minimally invasive, rigid lumbar fusion. The associated are not yet well described.The participants were patients who underwent OLIF surgery under diagnosis degenerative diseases between April 2013 and May 2015 at 11 affiliated medical institutions. collected data classified into intraoperative early-stage postoperative...
In Brief Study Design. Prospective trial. Objective. To examine the clinical efficacy of teriparatide for bone union after instrumented lumbar posterolateral fusion using local grafting in women with postmenopausal osteoporosis. Summary Background Data. Intermittent parathyroid hormone (PTH) treatment increases mass and reduces risk osteoporotic vertebral fractures. Recombinant human PTH (1–34) has already been approved as a severe Preclinical data support spinal fusion. However, results...
Surgery for lumbar spinal degeneration disease is widely performed. While posterior decompression and fusion are popular, anterior interbody (ALIF) also used treatment. Extreme lateral (XLIF) commonly noninvasive ALIF; however, several complications, such as nerve psoas muscle injury, have been reported. In the current study, we examined clinical efficacy complications of oblique (OLIF) disease.Thirty-five patients with degenerated spondylolisthesis, discogenic pain, kyphoscoliosis were...
Prospective case series.To examine the clinical efficacy of mini-open anterior retroperitoneal lumbar interbody fusion: oblique lateral fusion (OLIF) for degenerated spinal kyphoscoliosis.The existing surgical procedures treatment kyphotic deformity, including Smith-Petersen osteotomy, pedicle subtraction and vertebral column resection procedures, are invasive in nature. Extreme to provide less deformity has been reported, but complications nerve psoas muscle injury have noted. In current...
Age-related sarcopenia can cause various forms of physical disabilities. We investigated how affects degenerative lumbar scoliosis (DLS) and spinal canal stenosis (LSCS).Subjects comprised 40 elderly women (mean age 74 years) with disease whose chief complaints were low back pain lower limb pain. They included 15 cases DLS 74.8 25 LSCS 72.9 years). performed whole-body dual-energy X-ray absorptiometry (DXA) to analyze body composition, including appendicular trunk skeletal muscle mass index...

Objective: In recent years, there has been an increase in research on the therapeutic effects of exergaming, but have few studies these types interventions for chronic low back pain. this study, we hypothesized that Nintendo Ring Fit Adventure (RFA) exergame would be effective patients with pain, and conducted a randomized prospective longitudinal study. Materials Methods: Patients pain were included Twenty randomly selected (9 males 11 females, mean age 49.3 years) RFA group, exergaming was...
Emergency medical triage is crucial for prioritizing patient care in emergency situations, yet its effectiveness can vary significantly based on the experience and training of personnel involved. This study aims to evaluate efficacy integrating Retrieval Augmented Generation (RAG) with Large Language Models (LLMs), specifically OpenAI's GPT models, standardize procedures reduce variability care.
Retrospective case series.To examine the most effective duration of teriparatide use for spinal fusion in women with postmenopausal osteoporosis.We reported that daily subcutaneous injection (parathyroid hormone) significantly improved bone union after instrumented lumbar posterolateral (PLF) osteoporosis when compared oral administration bisphosphonate. However, has not been explored.Forty-five diagnosed degenerative spondylolisthesis from one three treatment groups were evaluated based on:...
Case series.To present the difficulty of diagnosing origin lower leg pain in patients with lumbar spinal stenosis and hip joint arthritis.Pain arising from a degenerated is sometimes localized to leg. Patients disease may also show radicular corresponding area. If both conditions only at leg, it difficult determine pain.We reviewed 420 who had diagnosed by myelography, computed tomography after or magnetic resonance imaging. Pain ipsilateral lateral aspect but slight low back around was...
Purpose: Osteoarthritic pain is largely considered to be inflammatory pain.Sensory nerve fibers innervating the knee have been shown significantly damaged in rat models of osteoarthritis (OA) which subchondral bone junction destroyed, and this induces neuropathic (NP).Pregabalin was developed as a killer for NP; however, there are no reports on pregabalin use OA patients.The purpose study investigate efficacy patients.Materials Methods: Eighty-nine patients were evaluated randomized...
Objective. To examine the analgesic effect of intradiscal administration a tumor necrosis factor-αα (TNF-α) inhibitor in patients with discogenic low back pain (LBP). Design. Prospective, randomized study. Setting. Department Orthopaedic Surgery, Chiba (Japan) University Hospital. Subjects. Seventy-seven diagnosed LBP. Methods. Discogenic LBP were randomly assigned to etanercept (n = 38; bupivacaine [2 mL] [10 mg]) or control 39; mL]) groups. Patients received single injection. Numerical...
Osteoarthritic (OA) pain is largely considered to be inflammatory pain. However, during the last stage of knee OA, sensory nerve fibers in are shown significantly damaged when subchondral bone junction destroyed, and this can induce neuropathic Several authors have reported that tumor necrosis factor-α (TNFα) a joint plays crucial role modulation. The purpose current study was evaluate efficacy etanercept, TNFα inhibitor, for OA.Thirty-nine patients with OA 2-4 Kellgren-Lawrence grading were...
Abstract We developed a new scaffold material—oriented collagen tubes (OCT)—and evaluated the potential of OCTs combined with basic fibroblast growth factor (bFGF) to repair 15 mm sciatic nerve defect in rats. The treatment groups consisted OCT adsorbed bFGF (OCT/bFGF group), phosphate‐buffered saline (PBS) (OCT/PBS and no‐treatment group (Defect group). Functional evaluation regeneration was performed using CatWalk system, histological analyses sites were also performed. In rats treated...
Finite element analysis (FEA) of the proximal femur has been previously validated with large mesh size, but these were insufficient to simulate model small implants in recent studies. This study aimed validate femoral computed tomography (CT)-based specimen-specific FEA smaller size using fresh frozen cadavers. Twenty femora from 10 cadavers (mean age, 87.1 years) examined. CT was performed on all specimens a calibration phantom. Nonlinear prediction stance configuration Mechanical Finder...
Controlled laboratory study.This study aimed to evaluate the efficacy of platelet-rich plasma (PRP) stored at room temperature (RT), frozen, or after freeze-drying.PRP enriches tissue repair and regeneration, is a novel treatment option for musculoskeletal pathologies. However, whether biological activity preserved during PRP storage remains uncertain.PRP was prepared from blood 12 healthy human volunteers (200 mL/person) using three methods: RT with shaking, frozen -80℃, freeze-dried RT....
Abstract The emergency department is an environment with a potential risk for diagnostic errors during trauma care, particularly fractures. Convolutional neural network (CNN) deep learning methods are now widely used in medicine because they improve accuracy, decrease misinterpretation, and efficiency. In this study, we investigated whether automatic localization classification using CNN could be applied to pelvic, rib, spine We also examined fracture detection algorithm help physicians...
