OBJECTIVE To evaluate the properties of a combination bone graft consisting of biphasic calcium phosphate ceramic, polyetheretherketone (PEEK) cage in one- and two-level surgery. METHODS Over a 12-month time period, a prospective single surgeon series of 75 patients were included in the study and 58 patients selected based on adequate data points. From these 58 patients, 32 were supplemented ...

OBJECTIVE To investigate the safety and efficacy of demineralized bone matrix (DBM) as a bone graft substitute for anterior cervical discectomy and fusion (ACDF) surgery. METHODS Twenty consecutive patients treated with ACDF using stand-alone polyestheretherketone (PEEK) cages (Zero-P) with DBM(CGDBM100) were prospectively evaluated with a minimum of 6 months of follow-up. Radiologic efficacy...

AIM Cervical disc herniation (CDH) can be treated using different anterior and posterior methods. Anterior cervical discectomy and fusion (ACDF) is currently gold standard and provides bony fusion and good clinical outcome. Recently many studies reported good clinical and radiological outcomes in cases who underwent anterior cervical discectomy (ACD) and reconstruction with empty cage. This stu...

INTRODUCTION Recently, novel polymers including polyetheretherketone (PEEK) and carbon fiber reinforced polymer (CFRP) have been used for spinal cages because of their advantages such as radiolucency, low incidence of artifacts on magnetic resonance imaging scans, less bone subsidence, and the capacity to tailor its mechanical properties, as well as its safety for patients with metal allergies....

Background: Decompression and fusion with autograft is the gold standard technique in the treatment of narrowing of the cervical canal. Using polyetheretherketone (PEEK) cages or nonabsorbable polymer boxes with elasticity similar to bone, radiolucent, and the same degree of fusion reduces morbidity. methods: We carried out a prospective, longitudinal, deliberate intervention case series with e...

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...

Background:   After cervical discectomy, autogenetic bone is packed into the cage to increase the rate of union between adjacent vertebral bodies, but donor site–related complications can still occur. In this study we evaluate the use   of hydroxyapatite granules as a substitute for autograft for interbody fusion.     Methods:   From November 2008 to November 2011, 236 patients participated in ...
