OBJECTIVE To analyze the surgical outcome of traumatic lumbosacral spondylolisthesis treated using posterior lumbar interbody fusion, and help spine surgeons to determine the treatment strategy. METHODS We reviewed retrospectively five cases of traumatic lumbosacral spondylolisthesis treated in our hospital from May 2005 to May 2010. There were four male and one female patient, treated surgic...

BACKGROUND This is a retrospective analysis of long-term results of treatment of dysplastic, isthmic and degenerative spondylolisthesis with interbody fusion and transpedicular screw fixation. MATERIAL AND METHODS Twenty-one patients underwent interbody fusion with the "Bialstab" transpedicular system. Anterior lumbar interbody fusion (ALIF) was subsequently performed in 2 patients. In the re...

BACKGROUND Plain radiographic assessment of posterolateral fusion has been reported as accurate in only two thirds of patients who were found to be healed at surgical exploration. Plain radiographic techniques for fusion assessment of interbody fusion with radiolucent cages are reported to be accurate. A helical computed tomography (CT) scan shows a high sensitivity for pseudarthrosis compared ...

We report 2 cases of transforaminal lumbar interbody fusion for failed Graf ligamentoplasty. Both patients had residual or recurrent low back pain and leg pain after Graf ligamentoplasty, caused by lumbar segmental instability or narrowing of their intervertebral foramens. The pain improved markedly after the revision surgery. We recommend transforaminal lumbar interbody fusion for failed Graf ...

Traumatic lumbar spondylolisthesis is a rare lesion and frequently noted in patients with multiple traumatic injuries. We report one case of L5 traumatic spondylolisthesis, which obtained successful decompression, reduction, interbody fusion and fixation by posterior lumbar interbody fusion, and got satisfactory outcome. We recommend early decompression, reduction, interbody fusion and fixation...

A major sequelae of lumbar fusion is acceleration of adjacent-level degeneration due to decreased lumbar lordosis. We evaluated the effectiveness of 4 common fusion techniques in restoring lordosis: instrumented posterolateral fusion, translumbar interbody fusion, anteroposterior fusion with posterior instrumentation, and anterior interbody fusion with lordotic threaded (LT) cages (Medtronic So...

Operative techniques for fusing an unstable portion of the lumbar spine or immobilizing a painful vertebral motion segment have been in use for many years. Lumbar fusion procedures initially were used to treat patients with infections (tuberculous spondylitis) or misaligned spines (isthmic spondylolisthesis) (1–8). Early techniques involving the use of harvested autogenous bone graft without in...

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 ...

The increasing adoption of minimally invasive techniques for spine surgery in recent years has led to significant advancements in instrumentation for lumbar interbody fusion. Percutaneous pedicle screw fixation is now a mature technology, but the role of expandable cages is still evolving. The capability to deliver a multiexpandable interbody cage with a large footprint through a narrow surgica...

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...
