STUDY DESIGN A retrospective study of 58 patients undergoing cantilever transforaminal lumbar interbody fusion (c-TLIF). OBJECTIVES To evaluate morphologic changes in the intervertebral foramen (IVF) on the side contralateral to spacer insertion in patients undergoing c-TLIF using plain x-ray films and computed tomography scan. SUMMARY OF BACKGROUND(More)
Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is a lysosomal storage disorder caused by deficiency of N-acetylgalactosamine-6-sulfate sulfatase, which results in systemic accumulation of glycosaminoglycans (GAGs), keratan sulfate and chondroitin-6-sulfate. Accumulation of these GAGs causes characteristic features as disproportionate dwarfism(More)
STUDY DESIGN Retrospective study of surgery for spondylolysis patients. OBJECTIVE To assess clinical outcome of bony union using multislice computed tomography after segmental wiring fixation. SUMMARY OF BACKGROUND DATA How bony union affects surgical outcome of spondylolysis repair is unclear. METHODS Forty-four athletes with symptomatic(More)
We report an extremely rare case with bilateral and symmetric dumbbell ganglioneuromas of the cervical spine in an elderly patient. A 72-year-old man came by ambulance to our hospital due to progressive incomplete paraplegia. Magnetic resonance imaging demonstrated bilateral symmetric dumbbell tumors at the C1/2 level. We performed total resection of the(More)
A patient with postlaminectomy kyphosis with a neurological deficit which developed following the initial surgical treatment is reported. A 49-year-old man, complaining of neck pain, sought treatment in 1995. An extramedullary cervical spinal tumor was diagnosed and C2-C4 laminectomy and resection of the tumor were performed. Recurrence of the tumor was(More)
PURPOSE This study aimed to compare the differences in functional recovery between patients undergoing plate and nail fixation in the very early period after surgery. METHOD This study was designed as a controlled clinical trial that included 18 patients who were surgically treated with either dynamic hip screw as plate fixation or proximal femoral nail(More)
Matrix metalloproteinase-1 (MMP-1, collagenase-1) plays a pivotal role in the process of joint destruction in degenerative joint diseases. We have examined the regulation of MMP-1 production in human chondrocytic HCS-2/8 cells stimulated by tumor necrosis factor-alpha (TNF-alpha). In response to TNF-alpha, MMP-1 is induced and actively released from HCS-2/8(More)
Calpain is secreted by intra-articular synovial cells and degrades the main components of cartilage matrix proteins, proteoglycan, and collagen, causing cartilage destruction. Matrix metalloproteinase-3 (MMP-3) has also been detected in synovial fluid and serum, and is involved in the development and progression of rheumatoid arthritis by degradation of the(More)
Although fat embolism syndrome is a well-known complication of fractures of the long bones or pelvis, fat embolism syndrome occurring subsequent to fracture of the lumbar spine is rare. We report a fatal case of fat embolism syndrome characterized by fat and bone marrow embolism that occurred 36 h after an isolated fracture-dislocation of the L1 vertebra. A(More)
Retrospective analyses of six cases. To describe six patients with previous failed laminoplasty who were subsequently managed by anterior cervical decompression and fusion (ACDF) using fibular strut as revision surgeries. While several complications and unsatisfactory results of cervical laminoplasty have been reported, there is no general consensus on how(More)
