AIMS To study the effect of a conditioning stimulus on an external urethral sphincter (EUS)contraction evoked by a magnetic stimulation at different time intervals. METHODS Seven healthy male volunteers underwent EUS pressure measurement. At baseline, magnetic stimulation of the lumbosacral spinal cord above the motor threshold was performed and evoked EUS pressure responses were recorded. Th...

OBJECTIVES To investigate whether the voiding dysfunction caused by spinal cord injury (SCI) in rats can be improved by i.v. administration of the serotonin (5-HT)2A/2C receptor agonist 2,5-dimethoxy-4-iodophenyl-2-aminopropanehydrochloride (DOI), and to discuss whether the mechanism can be ascribed to 5-HT2A and 5-HT 2C receptor upregulation in lumbosacral cord motoneurons. MATERIALS AND MET...

Patients with Bertolotti's syndrome have characteristic lumbosacral anomalies and often have severe sciatica. We describe a patient with this syndrome in whom standard decompression of the affected nerve root failed, but endoscopic lumbosacral extraforaminal decompression relieved the symptoms. We suggest that the intractable sciatica in this syndrome could arise from impingement of the nerve r...

We present a case of lumbosacral fracture-dislocation, which was spontaneously reduced during radiological examination. Such rapid reduction is, however, not reliable for long-term stability. We would like to report this case briefly because spontaneous reduction of lumbosacral fracture-dislocation has not been reported previously.

Most of the previously reported lumbosacral nerve root avulsions presented with pseudomeningoceles at the time of delayed initial imaging. We report a case of traumatic lumbosacral nerve root injury associated with an isolated femur fracture and demonstrate the evolution of pseudomeningoceles following nerve root avulsions and edema in the perineural fat identified on the initial MR imaging.

This is an evidence-based review of electrodiagnostic (EDX) testing of patients with suspected lumbosacral radiculopathy to determine its utility in diagnosis and prognosis. Literature searches were performed to identify articles applying EDX techniques to patients with suspected lumbosacral radiculopathy. From the 355 articles initially discovered, 119 articles describing nerve conduction stud...

BACKGROUND Sciatica has been classically described as pain in the back and hip with radiation in the leg along the distribution of the sciatic nerve, secondary to compression or irritation of the sciatic nerve. Spinal abnormality being the most common etiology, is one of the most common indications for MRI of the lumbosacral spine. Here we describe imaging findings secondary to a supralevator p...

Study Design Case report. Objective To analyze the surgical difficulties in restoring global spinal stability and to describe an effective surgical option for tuberculosis with extensive destruction of the lumbosacral spine. Advanced tuberculosis with destruction of the lumbosacral spine can result in a kyphosis or hypolordosis, leading to back pain, spinal instability, and neurological deficit...

BACKGROUND CONTEXT The prospective, double-blind, randomized, placebo-controlled study design is essential in the interventional spine literature to truly evaluate whether or not a procedure is effective. PURPOSE This article will critically evaluate the highest quality interventional spine literature with strict interpretation of the results of these trials. STUDY DESIGN Review article. ...

UNLABELLED Lumbosacral transitional vertebrae can alter the biomechanics of weight transfer at the affected spinal segment. Low-back pain may result. This study assessed what skeletal scintigraphy reveals about stress associated with a lumbosacral transitional vertebra in young patients with low-back pain. METHODS The study population included 48 patients (30 male, 18 female; age range, 6-19 ...
