Electrical stimulation promotes functional recovery after spinal cord injury by activating endogenous spinal cord-derived neural stem/progenitor cell: an in vitro and in vivo study.

Background Context: Electrical stimulation is a noninvasive treatment method that has gained popularity in the treatment of spinal cord injury (SCI). Activation of spinal cord-derived neural stem/progenitor cell (SC-NSPC) proliferation and differentiation in the injured spinal cord may elicit considerable neural regenerative effects.

Purpose: This study aimed to explore the effect of electrical stimulation on the neurogenesis of SC-NSPCs.

Psoas weakness following oblique lateral interbody fusion surgery: a prospective observational study with an isokinetic dynamometer.

Background Context: Although the surgical corridor used for oblique lateral interbody fusion (OLIF) protects the intrapsoas nerves by causing minimal compression, transient weakness remains the most commonly reported postoperative complication.

Purpose: Using a dynamometer to evaluate how the hip flexor strength changes following OLIF.

Study Design/setting: A prospective observational study.

Development of Neuromonitoring Pedicle Screw - Results of Electrical Resistance and Neurophysiologic Test in Pig Model.

Objective: To analyze the electrical resistance of a newly developed neuromonitoring pedicle screw (Neuro-PS) and to verify the electrophysiologic properties of the Neuro-PS in a pig model.

Methods: We developed 2 types of the Neuro-PS in which a gold lead was located internally (type I) and externally (type II). We measured the electrical resistance of the Neuro-PS and the conventional screw and analyzed the electrical thresholds of triggered EMG (t-EMG) of each screw by intentionally penetrating the medial pedicle wall and contacting the exiting nerve root in a pig model.

Dorsal Epidural Gas after Lumbar Microdiskectomy Treated with CT-guided Needle Aspiration.

To present a case of unusual dorsal epidural gas (EG) accumulation after a simple lumbar microdiskectomy (MD), treated with computed tomography (CT)-guided needle aspiration. A 78-year-old woman underwent simple lumbar MD at the L3-4 level. One week after the operation, the patient complained of severe back pain radiating to the right thigh.

Risk factors for cage migration and cage retropulsion following transforaminal lumbar interbody fusion.

Background Context: Transforaminal lumbar interbody fusion (TLIF) is a widely accepted surgical procedure, but cage migration (CM) and cage retropulsion (CR) are associated with poor outcomes.

Purpose: This study seeks to identify risk factors associated with these serious events.

Study Design: A prospective observational longitudinal study.

Recurrent esophageal perforation after anterior cervical spine surgery: case report.

Purpose: Delayed esophageal perforation after anterior cervical discectomy and fusion (ACDF) is an extremely rare cause of infection such as spondylodiscitis. We present a rare case in which a patient had two delayed esophageal perforations occurring 20 and 25 years after ACDF. By sharing our experience of this rare case, we hope to provide new information related to delayed esophageal perforation.

Relationships between vitamin D and paraspinal muscle: human data and experimental rat model analysis.

Background Context: Vitamin D deficiency (VDD) has been closely linked with skeletal muscle atrophy in many studies, but to date no study has focused on the paraspinal muscle.

Purpose: To verify paraspinal muscle changes according to serum vitamin D level.

Study Design: A cross-sectional study of patients who visited our hospital and an in vivo animal study.

Curcumin Increase the Expression of Neural Stem/Progenitor Cells and Improves Functional Recovery after Spinal Cord Injury.

Objective: To investigates the effect of curcumin on proliferation of spinal cord neural stem/progenitor cells (SC-NSPCs) and functional outcome in a rat spinal cord injury (SCI) model.

Methods: Sixty adult male Sprague-Dawley rats were randomly and blindly allocated into three groups (sham control group; curcumin treated group after SCI; vehicle treated group after SCI). Functional recovery was evaluated by the Basso, Beattie, and Bresnahan (BBB) scale during 6 weeks after SCI.

Primary eosinophilic granuloma of adult cervical spine presenting as a radiculomyelopathy.

We report a case of 29-year-old man diagnosed as a primary eosinophilic granuloma (EG) lesion of the seventh cervical vertebra. He had paresthesia on both arms, and grasping weakness for 10 days. Cervical magnetic resonance image (MRI) showed an enhancing mass with ventral epidural bulging and cord compression on the seventh cervical vertebra.

Valproic Acid increases expression of neuronal stem/progenitor cell in spinal cord injury.

Objective: This study investigates the effect of valproic acid (VPA) on expression of neural stem/progenitor cells (NSPCs) in a rat spinal cord injury (SCI) model.

Methods: Adult male rats (n=24) were randomly and blindly allocated into three groups. Laminectomy at T9 was performed in all three groups.
