STUDY DESIGN Prospective randomized noninferiority trial. PURPOSE To evaluate whether the union rate of anterior cervical discectomy and fusion (ACDF) using a polyetheretherketone (PEEK) cage filled with a mixture of hydroxyapatite (HA) and demineralized bone matrix (DBM) is inferior to that of a mixture of β-tricalcium phosphate (β-TCP) and HA. OVERVIEW OF LITERATURE There have been no cli...

OBJECTIVE The authors conducted a retrospective study to compare the implantation of carbon fiber composite frame cages (CFCFCs) to the implantation of polyetheretherketone (PEEK) cages after anterior cervical discectomy for cervical degenerative disc disease. In addition, the predictive factors that influenced fusion or subsidence were investigated. METHODS A total of 58 patients with single...

The aim of this study was to assess the performance of a new vacuum plasma sprayed (VPS) titanium-coated carbon/polyetheretherketone (PEEK) cage under first use clinical conditions. Forty-two patients who underwent a one or two segment transforaminal lumbar interbody fusion (TLIF) procedure with a new Ca/PEEK composite cage between 2012 and 2016 were retrospectively identified by an electronic ...

AIM The aim of this study is to compare the different types of fusion materials known as PEEK cages used during anterior cervical discectomy (ACD) surgery. MATERIAL AND METHODS A total of 67 patients were operated and evaluated retrospectively under two groups (group A: 35 PEEK cage patients, group B: 32 bladed PEEK cage patients) between 2009 and 2013. Preoperative and postoperative (postope...

BACKGROUND Anterior C2/3 discectomy and interbody fusion (ACDF) with plating is increasingly performed as the primary treatment of unstable Hangman's fracture; however, plate-related complications, such as screw back-out, plate fracture and soft-tissue injury, is not uncommon. Polyetheretherketone (PEEK) cage has now been developed to provide initial stability before fusion; however, whether an...

The author retrospectively studied twenty-two patients who underwent revision lumbar surgeries using ALLIF with a self-anchored stand-alone polyetheretherketone (PEEK) cage. The operation time, blood loss, and perioperative complications were evaluated. Oswestry disability index (ODI) scores and visual analog scale (VAS) scores of leg and back pain were analyzed preoperatively and at each time ...

Objective: A variety of newly designed grafts for transforaminal lumbar interbody fusion (TLIF) have been introduced for clinical application. Biomechanical properties of the LOOP® PEEK cage (Medtronic GmbH, Meerbusch, Germany) have been shown in cadaver laboratory investigations, but not in clinical studies so far. In this study we analyze the safety, clinical and radiological outcome of the L...

BACKGROUND A prospective cohort study was performed to evaluate the clinical and radiological outcomes following posterior lumbar interbody fusion (PLIF) in patients treated with a PEEK cage compared to those treated with an autologous cage using the lumbar spinous process and laminae (ACSP). METHODS Sixty-nine consecutive patients with lumbar degenerative disc disease were randomly assigned ...

BACKGROUND Anterior cervical diskectomy and fusion (ACDF) is a well-established surgical treatment. Several types of intervertebral spacers can be used, but there is increasing evidence that PEEK cages yield insufficient fusion and thus less clinical improvement. The study aim was to assess the outcomes of single-level ACDF with an empty PEEK cage partially coated with titanium. METHODS This ...

Back and radicular pain is the leading cause of activity and productivity loss amongst adults of any age in the United States [Ref. 1]. In many cases, surgical intervention is required, including at least 5,000 interbody spinal fusion cages implanted each month in the U.S. alone [Ref. 2]. The total U.S. market for spinal fusion implants was valued at nearly $4 billion in 2008 [Ref. 3]. Interbod...
