3D printed titanium banana interbody cages versus titanium-coated PEEK bullet cages for TLIF.

Introduction: Lumbar degenerative spinal disease is a common, major cause of pain and disability. Titanium and polyetheretherketone (PEEK) are popular materials for interbody implants although evidence is mixed on which material is superior in terms of fusion and subsidence. The purpose of this study was to evaluate the clinical outcome of 3D printed titanium (3DPT) cages in patients undergoing TLIFs, as well as complication profiles based on widely used outcome metrics and reoperation events.

A prospective evaluation of cellular bone matrix for posterolateral lumbar fusion.

Introduction: Autograft bone is the gold standard graft used in posterolateral lumbar intertransverse fusion (PLF) but can be limited by supply and donor site morbidity. Cadaveric cellular allografts represent an alternative source of graft material that avoids these limitations.

Objective: To assess the safety and efficacy of ViviGenCellular Bone Matrix in comparison to autograft bone in PLF.

Toxicity of additives present in conventional and biodegradable plastics on soil fauna: a case study of the root lesion nematode Pratylenchus neglectus.

Plastic pollution in terrestrial environments is a growing concern, with an increasing focus on the impact of plastic additives on soil ecosystems. We evaluated the impact of additives from conventional plastics (ACP) and biodegradable plastics (ABP) on the soil nematode, Pratylenchus neglectus. The additives represented five functional classes (antioxidants, colourants, flame retardants, nucleating agents, and plasticisers).

Comparison of intra-operative skull fixation techniques on cervical sagittal parameters.

Background: There is limited literature concerning the use of bi-vector traction to a Mayfield following posterior cervical fusion with respect to cervical alignment parameters. The objective of this study was to determine how variability of intra-operative fixation methods for posterior cervical fusion affects post-operative cervical sagittal alignment parameters.

Methods: After institutional review board (IRB) approval, retrospective chart review of a total of 54 patients who underwent posterior cervical fusion from July 2017 to December 2019 was conducted.

The effect of radiotherapy, chemotherapy, and immunotherapy on fusion rate in spinal surgery using osteobiologics for patients with metastatic spinal disease: a systematic review.

Objective: To evaluate the impact that adjuvant therapies like radiotherapy, chemotherapy, and immunotherapy have on osteobiologic properties and bony regeneration in patients with metastatic spine disease (MSD) undergoing spinal fusion surgery.

Methods: PubMed and ClinicalTrials.gov searches were performed.
