Finite Element Analysis of Stress Distribution and Range of Motion in Discogenic Back Pain.

Objective: Precise knowledge regarding the mechanical stress applied to the intervertebral disc following each individual spine motion enables physicians and patients to understand how people with discogenic back pain should be guided in their exercises and which spine motions to specifically avoid. We created an intervertebral disc degeneration model and conducted a finite element (FE) analysis of loaded stresses following each spinal posture or motion.

Methods: A 3-dimensional FE model of intervertebral disc degeneration at L4-5 was constructed.

The Effect of Evogliptin Tartrate on Controlling Inflammatory Pain.

: Evogliptin tartrate inhibits dipeptidyl peptidase-4 (DPP-4), boosting glucagon-like peptide 1 (GLP-1) secretion and improving insulin release and glucose tolerance, while also exerting anti-inflammatory effects. We investigated its anti-inflammatory and analgesic effects. : Forty male Sprague Dawley rats were divided into (N = 10 in each): (1) naïve, (2) complete Freund's adjuvant (CFA) inflammation + evogliptin tartrate (once for 10 mg/kg) (CFAE), (3) CFA + vehicle (same volume with normal saline with evogliptin tartrate/once) (CFAV), and (4) CFA + indomethacin (5 mg/mL/kg/1 time) (CFAI) groups.

Artificial Intelligence for Neurosurgery : Current State and Future Directions.

Artificial intelligence (AI) is a field of computer science that equips machines with human-like intelligence and enables them to learn, reason, and solve problems when presented with data in various formats. Neurosurgery is often at the forefront of innovative and disruptive technologies, which have similarly altered the course of acute and chronic diseases. In diagnostic imaging, such as X-rays, computed tomography, and magnetic resonance imaging, AI is used to analyze images.

Risk factors for reoperation after lumbar spine surgery in a 10-year Korean national health insurance service health examinee cohort.

Degenerative lumbar spine disease is becoming increasingly prevalent in the aging population. Surgical treatment is the standard treatment modality for intractable cases, but the reoperation rate remains high. We conducted this study to longitudinally evaluate the impact of health risk factors on the risk of lumbar spine reoperation in Koreans aged over 40 years.

A new surgical method for treating syringomyelia secondary to arachnoiditis following cervical spine surgery: the syringo-cisterna magna shunt.

Purpose: The 5-year postoperative failure rate of conventional shunt treatment for syringomyelia is 50%, with arachnoditis, shunt obstruction, and shunt malfunction being the most common causes. We report a new syringo-cisterna magna (SCM) shunt that allows syrinx cerebrospinal fluid (CSF) drainage normally into the cerebellomedullary cisterns through the subarachnoid space.

Methods: Between November 2012 and February 2017, six patients (mean age: 57.

Incidence, reasons, and risk factors for 30-day readmission after lumbar spine surgery for degenerative spinal disease.

This study investigated risk factors for 30-day readmission of discharged patients who had undergone lumbar spinal surgery. This retrospective, case-control study reviewed 3,933 patients discharged after elective spinal surgery for lumbar degenerative diseases from 2005 to 2012 at a university hospital. Of these patients, 102 were re-hospitalized within 30 days of discharge.

Efficacy of a Novel Annular Closure Device after Lumbar Discectomy in Korean Patients : A 24-Month Follow-Up of a Randomized Controlled Trial.

Objective: Lumbar discectomy is an effective treatment for lumbar disc herniation (LDH); however, up to 2-18% of patients with LDH have experienced recurrent disc herniation.
