INTRODUCTION Lumbosacral fracture dislocation is a rare entity mainly occurred in high-energy trauma accidents. In this unstable injury, anatomical separation of the spinal column from pelvis is usually associated with severe neurological deficits. CASE PRESENTATION We described a 16-year-old girl with extremely severe axial trauma to the lumbosacral spine who presented with fracture dislocat...

Electrodiagnostic findings of fibrillations and positive sharp waves in the lumbosacral paraspinals in patients without previous back surgery has been generally considered to be abnormal, consistent with posterior rami denervation. In some cases, it is the only abnormality on the electromyographic examination. This study was undertaken to determine the prevalence of abnormal spontaneous activit...

Five patients presenting with sensory-motor disturbances consistent with a clinical diagnosis of L5 or S1 radiculopathy were studied. All had conventional nerve conduction tests and electromyography. The lumbosacral roots were stimulated in the lumbosacral region by using the Cadwell MES-10 Magneto-electric stimulator. The compound muscle action potentials were recorded bilaterally by surface e...

We have studied fracture-dislocation of the fifth lumbar vertebra in seven patients and reviewed 50 previously reported cases. Based on this information, we have classified the injury into five types: type 1, unilateral lumbosacral facet-dislocation with or without facet fracture; type 2, bilateral lumbosacral facet-dislocation with or without facet fracture; type 3, unilateral lumbosacral face...

PURPOSE To evaluate prospectively the unoperated lumbosacral spine by gadolinium-enhanced MR for evidence of clinically correlative abnormal enhancement of nerve roots. METHODS Two hundred patients were prospectively studied with intravenous gadolinium- (0.1 mmol/kg) enhanced MR. Evidence was sought of intrathecal enhancement of lumbosacral nerve root(s), and the correlation of this enhanceme...

OBJECTIVES To test whether the position of lumbosacral dermatomes varies in the presence of transitional vertebrae. MATERIAL AND METHODS Fifty consecutive male patients were tested for thoracolumbar and lumbosacral transitional vertebrae by radiography and for the position of the dermatome gap between the lumbar dermatomes L1, L2, L3, and the sacral dermatomes S2 and S3. The dermatome gap was...

Lumbosacral dislocations are rare disorders; since they were first reported by Watson-Jones [1], only 100 cases have appeared in the literature [2]. A traumatic bilateral lumbosacral dislocation is even rarer, with a mere 10 cases reported [3]. Because of its low incidence and atypical location, the lesion may often go unnoticed on initial clinical assessment [4]. Surgical treatment modalities ...

BACKGROUND To identify dosimetric parameters associated with acute hematologic toxicity (HT) in rectal cancer patients undergoing concurrent chemotherapy and intensity-modulated pelvic radiotherapy. METHODS Ninety-three rectal cancer patients receiving concurrent capecitabine and pelvic intensity-modulated radiation therapy (IMRT) were analyzed. Pelvic bone marrow (PBM) was contoured for each...

introduction: transient receptor potential vanilloid type 1 (trpv1) and protein kinase cγ (pkcγ) are involved in sensitization/desensitization to noxious stimuli. we aimed to examine the gene expression levels of trpv1 and pkcγ in rat lumbosacral cord and midbrain on days 1, 4 and 8 of induction of morphine analgesic tolerance. methods: two groups of male wistar rats received twice daily saline...

This paper reports a rare case of a lumbosacral dislocation associated with symphysis pubis separation and cauda equina syndrome. A 39-year-old male who diagnosed traumatic lumbosacral dislocation underwent an open reduction without fusion. After an open reduction and internal fixation of a symphysis pubis separation, a missed lumbosacral dislocation was diagnosed and an open reduction was perf...
