PURPOSE The lateral transpsoas interbody fusion (LTIF) is an increasingly popular minimally invasive technique for lumbar interbody fusion. Although a posterior approach to the lumbar spine has traditionally been favored for the treatment of canal stenosis and neural foraminal stenosis, a growing body of evidence suggests that indirect decompression of the spinal canal and neural foramen can be...
[Purpose] The objective of this study was to propose a work environment that could reduce musculoskeletal workload. Accordingly, spinal muscle fatigue caused by ultrasound therapy at various treatment table heights was examined and compared. [Subjects and Methods] Twenty-five healthy subjects participated in this experiment. The table height was set to 100%, 125%, and 150% of the stool height (...
Lateral approaches to the lumbar disc space have become popular in recent years with very few reported complications. We report on a rare case of a stand-alone cage migration. A 77-year-old female presented with a right L2-3 radiculopathy that was refractory to maximum medical management. This was secondary to foraminal compression at L2-3 and L3-4 due to degenerative disc disease and levoscoli...
A 40 year-old man with C5 complete quadriplegia, had L2-L3 pyogenic spondylitis treated with debridement and fusion of the lumbar spine with left iliac bone graft. Three months later he developed symptoms of autonomic dysreflexia, including headache, cold sweating, and hypertension whenever he was in an upright position. These symptoms resolved after lying down. Roentgenograms of the lumbar spi...
The effect of incadronate, a third-generation bisphosphonate, was evaluated in rats with corticosteroid-induced osteopenia. Male Wistar rats were treated with methylprednisolone acetate (1 mg/kg, s.c.) once daily, 3 days a week for 12 weeks. Other groups received simultaneous treatment with methylprednisolone acetate and incadronate (0.03, 0.3 or 3 mg/kg, p.o.); incadronate was given once daily...
The purpose of this study was to investigate the association of the g.27667T>A genetic variant in the osteoprotegerin (OPG) gene with bone mineral density (BMD) and osteoporosis. A total of 393 primary osteoporosis subjects and 402 healthy controls were recruited. The BMD of the femoral neck hip, lumbar spine (L2-4), and total hip were evaluated by Norland XR-46 dual-energy X-ray absorptiometry...
Study Design Case report. Objective Presentation of an unusual case of an elderly patient with massive intradural disk herniation at the L2-L3 level. Methods Clinical and imaging data are presented after obtaining informed consent from the patient. Results A 90-year-old man suffering from sudden-onset neurogenic bladder dysfunction and lower back pain but no further neurologic deficits initiall...
Object: Previous reports have indicated that the level of lumbar spinal canal stenosis (LSCS) often differs from that diagnosed from neurological symptoms, and L5 nerve roots are often affected by stenosis at the L2–L3 or L3–L4 level; however, few cases have been described. Decompression surgery for upper lumbar spinal canal stenosis (LSCS) of L2–L3 and L3–L4 causing L5 and S1 symptoms was inve...
Osteochondroma (or osteocartilaginous exostosis) is the most common bone tumor of childhood, with an incidence ranging from 1 to 1.4 per 1,000,000. In the lumbar spine, osteochondromata usually arise from the posterior column at the secondary ossification center and grow away from the spinal canal without causing neurologic deficits. This article reports a rare intraspinal lumbar osteochondroma...
Although the mammalian locomotor CPG has been localized to the lumbar spinal cord, the functional-anatomical organization of flexor and extensor interneurons has not been characterized. Here, we tested the hypothesis that flexor and extensor interneuronal networks for walking are physically segregated in the lumbar spinal cord. For this purpose, we performed optical recordings and lesion experi...
