An 84-year-old man experienced right buttock pain that radiated gradually to his right lower extremity over a few months before admission. MRI revealed a space occupying intraspinal lesion that was close to the right-sided L4-L5 facet joint and an extraspinal lesion posterior to the right-sided L5 lamina. The lesions appeared as hyperintense areas on T1 weighted images and heterogeneous areas o...

Hacking applied a method involving the labeling of sequent members to the problem of giving a Gentzen-style system for S 5, called L5, formulated with strict implication and no special modal operator. The method was generalized to a labeling of hypersequents by G. Mints. In this paper, we show how this generalization eliminates an “anti-symmetry” in Hacking’s system and greatly simplifies L5. W...

Methods and materials A retrospective study of 170 asymptomatic adolescent volunteers was performed and all of them had the standing whole-spine lateral radiography. All subjects were divided into 3 groups by age: Group A (10-12 years), Group B (13-15 years), and Group C (16-18 years). Four different radiographic parameters were measured: lumbar lordosis (LL, L1-L5), thoracic kyphosis (TK, T4-T...

BACKGROUND Using a rat L5 spinal nerve transection model we previously showed that pentoxifylline prevents hyperalgesia through antiinflammation in the prefrontal brain. In this study, we examined efficacy when applied after injury. METHODS We examined the effect of pentoxifylline on existing mechanical allodynia, observing glial activation and proinflammatory cytokine expression in the lumba...

Lumbar disc herniation is common and may be symptomatic. The magnetic resonance imaging (MRI) scan is an appropriate tool to confirm the diagnosis and affected level of the spine. While a disc herniation is usually associated with ipsilateral symptoms, a few cases have been reported to present with contralateral symptoms. We report a unique case of left lumbar disc herniation at L5/S1 who prese...

A 43-year-old drug addicted female was referred for a L5-S1 posterolateral in situ fixation with autologous graft because of an L5/S1 severe discopathy with listhesis. After six months, low back pain recurred. A Tc-99m HDP SPECT-CT diagnosed a pseudarthrosis with intense uptake of the L5-S1 endplates and a fracture of the right S1 screw just outside the metal-bone interface without any uptake o...

Room-temperature (RT) mechanical anisotropy limits the broad applications of wrought magnesium (Mg) alloys. To weaken anisotropy, here, we proposed a design idea to create mixed texture. In present study, successfully fabricated Mg-3Y/Mg-5Li (W3/L5, wt.%) laminated composite, having texture with closely orthotropic shape, consisting an ED-split component in W3 layer and TD-split L5 layer, via b...
