PURPOSE The aim of this study was to investigate the biomechanical stability provided by a novel, polylactic acid/nano-sized, β-tricalcium phosphate, bioabsorbable, self-retaining cervical fusion cage (BCFC). METHODS Quasistatic nonconstraining torques (maximum 1.5 NM) induced flexion, extension, lateral bending (±1.5 NM), and axial rotation (±1.5 NM) on 32 sheep cervical spines (C2-C5). The ...
TLIF (transforaminal lumbar interbody fusion) is a method of interbody fusion, which is alternative to other vertebral fusion wherein, with an approach through intervertebral foramen, through lateral segment of intervertebral space, complications occurring with other methods are reduced. Today, there are numerous versions of this method in terms of implants and transplants. At our Department pa...
Abstract Background We developed a porous Ti alloy/PEEK composite interbody cage by utilizing the advantages of polyetheretherketone (PEEK) and titanium alloy (Ti alloy) in combination with additive manufacturing technology. Methods Porous cages were manufactured using various controlled porosities. Anterior intervertebral lumbar fusion posterior augmentation performed at three vertebral levels...
Study Design Retrospective case series. Purpose To examine the efficacy of platelet-rich plasma (PRP) for bone fusion in transforaminal lumbar interbody fusion (TLIF) using local bone grafting. Overview of Literature Several authors have reported the efficacy of PRP for bone union in animal models. However, the use of PRP for bone fusion in TLIF surgery has not been fully explored. Method...
STUDY DESIGN Cross-sectional survey study. OBJECTIVE To determine what are the most commonly used graft materials in anterior cervical discectomy and fusion and whether the choice of graft is affected by surgeon's training, years in practice, geographic location, practice setting, or surgeon's perceived difficulty in achieving fusion. METHODS A 23-question survey was sent out to 5334 surgeo...
BACKGROUND The traditional posterior lumbar interbody fusion (PLIF) technique usually involves implantation of two cages through a bilateral approach and bilateral laminectomy, which requires bilateral transpedicle screw fixation. The procedure itself has several negative impacts. Therefore, a modified PLIF procedure that includes insertion of a unilateral cage through the symptomatic side with...
