  Background & Objective : The preferred Selection of the anterior cervical discectomy alone, with iliac crest bone graft fusion and using the PEEK cage is still in controversial in degenerative disc disease. The aim of this study is comparing them on radiographic and clinical results. Materials & Methods: The all consecutive patients in the three hospitals in Tehran between the 2000 up to the ...

STUDY DESIGN An experimental pilot study using an acrylic interbody cage in a dog cervical spine fusion model. OBJECTIVE To compare bony fusion in autologous bone grafting with a novel acrylic cage in terms of preservation of disc height, biomechanical properties, and histologic characteristics. SUMMARY OF BACKGROUND DATA Degenerative diseases of cervical intervertebral discs are commonly t...

Study Design A retrospective clinical case series. Purpose To determine the strength of association between cage retropulsion and its related factors. Overview of Literature Lumbar interbody fusion with cage can obtain a firm union and can restore the disc height with normal sagittal and coronal alignment. Although lumbar interbody fusion procedures have satisfactory clinical outcomes, peri...

Objective The authors prospectively analyzed the effect of one-level or two-level anterior cervical discectomy and fusion (ACDF), comparing stand-alone cages and cage-with-plate fixation constructs with respect to clinical outcomes and radiologic changes. Methods A total of 84 patients who underwent one-level (n=52) or two-level ACDF (n=32) for cervical disc disease and who completed 2 years ...

Posterior lumbar interbody fusion (PLIF), as recommended with bilateral lumbar interbody cages and pedicle screw fixation, has increased the successful fusion rate to nearly 100%. Presently, a unilateral approach to the disc space with a variant of PLIF, the trans-foraminal interbody fusion is often used. There are few clinical studies of unilateral interbody fusion. The clinical and fusion res...

Background: Interbody cage stabilization as a stand-alone procedure in lumbar spine fusion is questioned due to inconsistent mechanical effects registered in human cadaveric studies. Even segmental mobility exceeding the normal range of motion is described after cage implantation. For the anterior interbody cage fusion, this potential, undesired destabilization is explained by the resection of ...
