In Brief Study Design. A histologic, biologic, and immunohistochemical assessment using human samples of lumbar ligamentum flavum. Objective. To clarify the pathomechanism loss elasticity hypertrophy flavum (LF) in elderly population. Summary Background Data. The most common spinal disorder patients is canal stenosis, causing low back leg pain, paresis. Canal narrowing, part, results from LF. Although histologic biologic literature on this topic available, LF still unknown. Methods. One...
Study Design. A retrospective review of prospectively collected data. Objective. The aim this study was to investigate recent outcomes conservative treatment for bony healing in pediatric patients with lumbar spondylolysis (LS) and identify the problems that need be resolved. Summary Background Data. Several diagnostic therapeutic techniques LS have been developed recently, leading better healing. Methods. Overall, 63 consecutive (53 boys 10 girls) (average age: 13.8 years; range: 6–17...
Background: Endoscopic lumbar decompression is useful for the treatment of various spinal conditions and being performed in an increasing number patients worldwide. We reviewed surgery-related complications who underwent endoscopic surgery discuss learning curve this procedure.
A biomechanical study.To compare, in cervical vertebrae (C3-C6), the pullout strengths of pedicle screws and lateral mass after both types screw had been subjected to a period cyclic loading 2 planes.In posterior subaxial fixation systems, are usually inserted into mass. As an alternative fixation, became popular 1990s was first used for lower spine trauma cases. However, it is controversial as whether upper-middle offers much security compared with fixation.For each 32 vertebrae, 1 side...
Lumbar spondylolysis, a stress fracture of the pars interarticularis, is prevalent in adolescent athletes. Recent advances diagnostic tools and techniques enable early diagnosis before these fractures progress to complete through pars. However, because patients often consult family physicians for primary care low back pain may not have access modalities such as magnetic resonance imaging (MRI) computed tomography, can be missed. This study surveyed prevalence symptomatic spondylolysis...
Connective tissues such as tendon, ligament and cartilage are mostly composed of extracellular matrix (ECM). These insoluble, mainly due to the highly cross-linked ECM proteins collagens. Difficulties obtaining suitable samples for mass spectrometric analysis render application modern proteomic technologies difficult. Complete solubilization them would not only elucidate protein composition normal but also reveal pathophysiology pathological tissues. Here we report complete human Achilles...
The pedicle screw (PS) system is widely used for spinal reconstruction. Recently, insertion using the cortical bone trajectory (CBT) technique has been reported to provide increased holding strength of vertebra, even in an osteoporotic spine. CBT also beneficial due its low invasiveness. We have performing hybrid reconstruction with at cranial level and PS caudal based on concept minimal applied this 6 cases degenerative spondylolisthesis. Surgery was completed a small skin incision around...
Study Design. Using fresh cadavers, real-time dosimeters were used to estimate the radiation exposure dose from C-arm fluoroscopy surgeons, medical staff, and patients during various procedures. Objective. The aim of this study was evaluate fluoroscopy, which is generate images human body, under a variety conditions in different areas. Summary Background Data. Awareness harmful effects long-term low-dose rising. There are no all-inclusive reports evaluating staff associated with fluoroscopic...
The mechanisms driving bone marrow stem cell mobilization are poorly understood. A recent murine study found that circulating marrow-derived osteoprogenitor cells (MOPCs) were recruited to the site of recombinant human morphogenetic protein-2 (BMP-2)-induced formation. Stromal cell-derived factor-1α (SDF-1α) and its cellular receptor CXCR4 have been shown mediate homing injured tissues. We hypothesized chemokines, such as SDF-1, also involved with cells. CD45(-) fraction is a major source...
Spinal cord transection and peripheral nerve cause muscle atrophy fiber type conversion. It is still unknown how spinal each affect the differentiation of conversion mechanism atrophy. The aim our study was to evaluate difference weight change, conversion, Peroxisome proliferator-activated receptor-γ coactivatior-1α (PGC-1α) expression brought about by transection.Twenty-four Wistar rats underwent surgery, control a laminectomy; injury group transection; denervation sciatic transection. were...
Study Design. Using fresh cadavers, the biomechanical testing were used to examine pullout strength of each pedicle screw. Objective. The aim this study was evaluate (1) a redirected screw following lateral wall breach; (2) end-plate and (3) without redirection after breach redirection. Summary Background Data. Screw malposition, such as or breach, is one main pitfalls inserting screws. Methods. From 17 spines, 54 vertebrae harvested. In vertebra on pedicle, inserted correctly down axis...
