A 3-year-old girl presented with a history of low back pain. The initial X ray showed spondylolysis and minimal anterior spondylolisthesis at L5-S1 (Figure 1). Lumbar MRI showed extraforaminal disc protrusion with intervertebral disc height loss, vertebral endplate signal abnormality in L4-L5 vertebral bodies, left soft tissue abnormal signal from L2 to S1 and medial aspect of psoas muscle (Fig...

A single-center retrospective comparative study was designed to identify the risk factors for restenosis of lumbar foraminal stenosis (LFS) after microscopic foraminal decompression (MFD). 21 consecutive patients who underwent single-level MFD with an average of 19-month follow-up were divided into two study groups based on clinical outcomes; group 1 (7 patients with poor outcomes requiring rev...

Patients with Klippel-Feil syndrome (KFS) have an increased incidence of vascular anomalies as well as vertebral artery (VA) anomalies. In this article, we presented imaging findings of a 15-year-old female patient with KFS with a rare association of extraforaminal cranially ascending right VA that originated from the ipsilateral carotid bulb. Trifurcation of the carotid bulb with VA is a very ...

STUDY DESIGN Cadaveric Biomechanical and Radiographic Analysis. OBJECTIVE The purpose of this study was to quantify the changes in intervertebral height and lateral and central recess areas afforded by lateral interbody fusion cages with 2 supplemental forms of internal fixation in cadaveric specimens. BACKGROUND DATA When conservative treatment for symptomatic lumbar stenosis fails, tradit...

STUDY DESIGN Prospective nonrandomized study. PURPOSE To find a possible correlation between clinical outcome and extent of lumbar spondylolisthesis reduction. OVERVIEW OF LITERATURE There is no consensus in the literature concerning whether a beneficial effect of reduction on outcome can be expected following reduction and surgical fusion for low grade lumbar spondylolisthesis. METHODS F...

OBJECTIVE To determine the effects of a minimally invasive transilial vertebral (MTV) blocking procedure on the computed tomographic (CT) appearance of the lumbosacral (L7/S1) junction of dogs with degenerative lumbosacral stenosis (DLSS). STUDY DESIGN Prospective study. ANIMALS 59 client-owned dogs with DLSS. METHODS Lumbosacral CT images were acquired with hyperextended pelvic limbs bef...
