background: anterior interbody fusion of the cervical spine have become the gold standard for treating spinal diseases, hence the aim of this study was to compare long term follow up results in patients with cervical disk disease treated with anterior peek cage implantation and without it in anterior approach. methods: retrospectively 63 patients with known cervical discogenic disorders who wen...

Aim To compare anterior fusion in standalone anterior lumbar interbody fusion (ALIF) using cage and screw constructs and anterior cage-alone constructs with posterior pedicle screw supplementation but without posterior fusion. Methods Eighty-five patients underwent single- or two-level ALIF procedure for degenerative disk disease or lytic spondylolisthesis (SPL). Posterior instrumentation was p...

BACKGROUND Initial promise of a stand-alone interbody fusion cage to treat chronic back pain and restore disc height has not been realized. In some instances, a posterior spinal fixation has been used to enhance stability and increase fusion rate. In this manuscript, a new stand-alone cage is compared with conventional fixation methods based on the finite element analysis, with a focus on inves...

This report is a rare case of a lumbar interbody fusion cage dislocation in the procedure of Minimal Invasive Transforaminal Lumbar Interbody Fusion surgery (MI-TLIF) for spondylolisthesis of segment L5/S1. A 65-year-old lady underwent MI-TLIF surgery, and the interbody fusion cage was dislocated forward into retroperitoneal space. The cage was extraction with lateral approach and replaced by l...

Transforaminal lumbar interbody fusion (TLIF) is commonly used procedure for spinal fusion. However, there are no reports describing anterior cage dislodgement after surgery. This report is a rare case of anterior dislodgement of fusion cage after TLIF for the treatment of isthmic spondylolisthesis with lumbosacral transitional vertebra (LSTV). A 51-year-old man underwent TLIF at L4-5 with post...

A variety of implant-related short and long-term complications after lumbar fusion surgery are recognized. Mid to long-term complications due to cage migration and/or cage subsidence are less frequently reported. Here, we report a patient with a complete cage migration into the superior adjacent vertebral body almost 20 years after the initial posterior lumbar interbody fusion procedure. In thi...

BACKGROUND The use of an interbody fusion device (cage) to assist fusion and increase intervertebral stability is widely supported. We applied the morselized impacted bone graft method without using a cage in a single level interbody fusion with encouraging medium-term clinical results. The purpose of this paper is to compare the clinical and radiological results of local bone grafts with a cag...

BACKGROUND One- and two-level lumbar interbody fusion with unilateral instrumentation is as effective as that with bilateral instrumentation. The height of the interbody cage influences the operated segment stability and the fusion technique success. The purpose of this research was to determine the effect of the fusion cage height (i.e. long and short) on both the stability (based on flexibili...

Study design: An in vitro biomechanical flexibility and fatigue test comparing two different lumbar interbody fusion cages using mono segmental lumbar spine specimens. Objective: To investigate and compare the stabilizing effect of a transforaminal lumbar interbody fusion (TLIF) cage against an expandable posterior lumbar interbody fusion (PLIF) cage. Method: Six intact human lumbar spine segme...

Although posterior lumbar interbody fusion (PLIF) is a widely accepted procedure, perioperative and postoperative complications are still encountered. In particular, cage migration can result in severe sequelae, and revision surgery is technically demanded. Here, we report a rare case of repeated migration of a fusion cage after PLIF. To the best of our knowledge, no report has been previously ...
