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...

BACKGROUND CONTEXT The lateral transpsoas approach to interbody fusion is gaining popularity because of its minimally invasive nature and resultant indirect neurologic decompression. The acute biomechanical stability of the lateral approach to interbody fusion is dependent on the type of supplemental internal fixation used. The two-hole lateral plate (LP) has been approved for clinical use for ...

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: Cervical spondylotic radiculopathy and myelopathy are common problems for which anterior cervical discectomy fusion is a gold standard procedure. There various implant options available, two of commonly used in practice. Anterior cage with plate locking standalone cage. Our study aims to compare these methods know the functional radiological outcomes after Materials Methods: We perf...

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...

BACKGROUND Interbody fusion surgery has been considered by many to be a treatment of choice for instability in lumbar degenerative disc disease. A posterior lumbar interbody fusion (PLIF) has the advantages of spinal canal decompression, anterior column reconstruction, and reduction of the sagittal slips from a single posterior approach. The PLIF using double cage was a standard practice till m...

AIM: The aim of this study was to evaluate the efficacy of cage-assisted fusion in three and four level cervical arthrodesis without additional anterior plating in patients with normal bMD. We hypothesized that omitting the use of long anterior cervical plate in multi-level ACDF will simplify the surgery, reduce the surgical time, avoid excessive and prolonged retraction on esophagus and caroti...

Between January 1996 and December 2005, a total of 1241 patients underwent anterior cervical decompression and fusion for cervical degenerative diseases in the authors' institution. Sixty-three (5.1%) patients underwent revision anterior cervical diskectomy and fusion for adjacent segment disease between October 2003 and August 2010. This series included 35 men and 28 women with a mean±SD age o...

OBJECTIVE We compared the clinical and radiographic outcomes of stand-alone polyetheretherketone (PEEK) cage and Zero-Profile anchored spacer (Zero-P) for single level anterior cervical discectomy and fusion (ACDF). METHODS We retrospectively reviewed 121 patients who underwent single level ACDF within 2 years (Jan 2011-Jan 2013) in a single institute. Total 50 patients were included for the ...
