Comparison of outcomes and safety of using hydroxyapatite granules as a substitute for autograft in cervical cages for anterior cervical discectomy and interbody fusion
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 ...
متن کاملStability After Anterior Lumbar Fusion with Interbody Cages: A Radiostereometric Evaluation
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 ...
متن کاملAnalysis of the correlative factors in the selection of interbody fusion cage height in transforaminal lumbar interbody fusion.
BACKGROUND Selecting an interbody cage with appropriate height is one of the key steps in lumbar interbody fusion, and has an important impact on clinical efficacy. How to choose the appropriate height of the cage becomes one of the core problems of lumbar interbody fusion for spine surgeons. However, studies about objective selection criteria on interbody cage height was rare. METHODS One hu...
متن کاملDoes TLIF aggravate adjacent segmental degeneration more adversely than ALIF? A finite element study.
AIM To determine whether transforaminal lumbar interbody fusion aggravate adjacent segmental degeneration more adversely than anterior lumbar interbody fusion. MATERIAL AND METHODS A normal finite element model, an anterior lumbar interbody fusion model and a transforaminal lumbar interbody fusion model of L3-5 were developed. 800 N compressive loading plus 10 Nm moments simulating flexion, e...
متن کاملDoes disc space height of fused segment affect adjacent degeneration in ALIF? A finite element study.
AIM The restoration of disc space height of fused segment is essential in anterior lumbar interbody fusion, while the disc space height in many cases decreased postoperatively, which may adversely aggravate the adjacent segmental degeneration. However, no literature available focused on the issue. MATERIAL AND METHODS A normal healthy finite element model of L3-5 and four anterior lumbar inte...
