Cranial flap fixation in sheep using a resorbable bone adhesive.

Objective: The authors' goal in this study was to investigate the use of a novel, bioresorbable, osteoconductive, wet-field mineral-organic bone adhesive composed of tetracalcium phosphate and phosphoserine (TTCP-PS) for cranial bone flap fixation and compare it with conventional low-profile titanium plates and self-drilling screws.

Methods: An ovine craniotomy surgical model was used to evaluate the safety and efficacy of TTCP-PS over 2 years. Bilateral cranial defects were created in 41 sheep and were replaced in their original position.

Benefit of Transforaminal Lumbar Interbody Fusion vs Posterolateral Spinal Fusion in Lumbar Spine Disorders: A Propensity-Matched Analysis From the National Neurosurgical Quality and Outcomes Database Registry.

Background: Despite increasing use and potential benefits of transforaminal lumbar interbody fusion (TLIF) compared with posterolateral spinal fusion (PSF), previous studies have not documented improved clinical outcomes with TLIF vs PSF.

Objective: To compare the outcomes of TLIF with PSF in patients with spondylolisthesis, spinal stenosis, and adjacent level disease.

Methods: The National Neurosurgical Quality and Outcomes Database was queried for patients who had a lumbar fusion.

Endovascular treatment for acute paraplegia after epidural steroid injection in a patient with spinal dural arteriovenous malformation.

Spinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal arteriovenous malformations. Type 1 spinal arteriovenous malformations are defined by the presence of radiculomeningeal feeders that drain into intradural veins. Patients with these lesions frequently present with chronic myelopathy, which is most often caused by venous hypertension.

Randomized, prospective, and controlled clinical trial of pulsed electromagnetic field stimulation for cervical fusion.

Background Context: Multilevel fusions, the use of allograft bone, and smoking have been associated with an increased risk of nonunion after anterior cervical discectomy and fusion (ACDF) procedures. Pulsed electromagnetic field (PEMF) stimulation has been shown to increase arthrodesis rates after lumbar spine fusion surgery, but there are minimal data concerning the effect of PEMF stimulation on cervical spine fusion.

Purpose: To determine the efficacy and safety of PEMF stimulation as an adjunct to arthrodesis after ACDF in patients with potential risk factors for nonunion.
