Lumbar spine and proximal femoral bone densities of Caucasian women, aged 35-45, were measured by dual photon densitometry model DPX. The measurement sites were assessed at the lumbar spine (vertebrae L2 to L4) and at the proximal femur (trochanter, femoral neck and Ward's triangle). After exclusion of women with climacteric symptoms, sterilized patients or those with menopausal concentrations ...

In performing neuraxial procedures, knowledge of the location of the conus medullaris in patients of all ages is important. The aim of this study was to determine the location of conus medullaris in a sample of newborn/infant cadavers and sagittal MRIs of children, adolescents, and young adults. The subjects of both the samples were subdivided into four developmental stages. No statistical diff...

Knowledge of lumbar coupling biomechanics is foundational in many manual therapy disciplines. 3-D studies of lumbar coupling indicate that coupling direction may not be predictable. The purpose of this study was to investigate physiotherapists' perception of importance of lumbar coupling for validation of manual therapy, necessity in treatment, and perceived direction of lumbar coupling biomech...

Lumbar diskectomy is a common procedure in neurosurgery, besides the common complications broken scalpel blade during disc removal is a rare event. Usually retrieval of such sharp retained fragments in same sitting is difficult and to prevent further complications another session is warranted [1]. We report a case of broken scalpel blade during L1-L2 lumbar intervertebral disc removal and succe...

A 61-year-old man presented with a 4-month history of progressive vision loss and paresthesia between the right L2-L4 dermatome. Funduscopy revealed severe bilateral papilledema (figure 1). Head CT showed mild hydrocephalus. CSF from a lumbar puncture at the L4-L5 level was xanthochromic with an elevated protein level (4,350 mg/dL). Lumbar spine MRI demonstrated a large intradural tumor at the ...

[Purpose] This study assessed the reliability and validity of an ultrasound-based imaging method for measuring the interspinous process distance in the lumbar spine using two different index points. [Subjects and Methods] Ten healthy males were recruited. Five physical therapy students participated in this study as examiners. The L2-L3 interspinous distance was measured from the caudal end of t...

A 72-year-old woman without a history of spinal injury was admitted to our hospital with prolonged severe back pain and high fever. Clinical laboratory findings and magnetic resonance imaging (MRI) revealed severe inflammation of the L2 and L3 lumbar vertebrae. Meropenem trihydrate administration improved her symptoms. Klebsiella pneumoniae isolated from the patient's blood indicated that the o...

OBJECTIVE: To evaluate the prognostic value of bowel loops dilatation as a finding on radiographs in the development and mortality of neonates with necrotizing enterocolitis. MATERIALS AND METHODS: On abdominal radiographs of 53 patients for diagnostic suspicion of necrotizing enterocolitis, the major diameters of dilated bowel loops (AD) were measured, as well as the distance between the upper...

The present study was conducted to examine the effects of body weight on intradiscal pressure (IDP) and annulus stress of intervertebral discs at lumbar spine. Three-dimensional finite element model of osseoligamentous lumbar spine was developed subjected to follower load of 500 N, 800 N, and 1200 N which represent the loads for individuals who are normal and overweight with the pure moments at...

Introduction: Intradural spinal cord tumors are uncommon with an incidence of 3 per 100,000 individuals. Multiple reports concerning intraspinal hematomas with neurologic deterioration following spinal needle insertion exist, but few reports have confirmed intraspinal hemorrhages from an undiagnosed lumbar ependymoma after attempted spinal anesthesia. Methods: A 22-year-old male with progressiv...
