BACKGROUND:  Anterior cervical fusion (ACF) with autologous bone was reported > 50 years ago. The continuous development of materials with elastic properties close to that of the cortical bone improves induction of osteogenesis and simplifies the technique of interbody fusion. To determine the safety and efficiency of stand-alone trabecular metal (TM) (or porous tantalum) cages for ACF, we performed a retrospective analysis of 88 consecutive patients with one-level or two-level degenerative disk disease (DDD) causing cervical myelopathy treated by interbody fusion with stand-alone TM cages...

A new miniplate applied differently from conventional application method for bone fixation has been developed. The novel approach is the insertion of the screw into the bone before miniplate installation. This study aimed to assess the stress distribution of a newly designed Yang's Keyhole (YK)- plate for segmental-bone fixation during sagittal split ramus osteotomy (SSO). Moreover, the effectiveness of the YK-plate system based on the clinical results was determined. The YK-plate system has a widened hole in the anterior region to permit a screw-head to be screwed through the system...

Objective: The use of open reduction and internal fixation (ORIF) for unstable pelvic injuries is associated with extensive blood loss, iatrogenic neurovascular injury, and infection. Moreover, the placement of sacroiliac (SI) screws is a blinded procedure, guided primarily by palpation and two-dimensional radiological screening, which demands expertise. The complex three-dimensional anatomy of SI joint and its proximity to neurovascular structure require a safe and precise technique...

BACKGROUND: Anterior chest wall numbness after plate fixation of clavicular shaft fractures is a common complication. This is usually related to damage of the branches of the supraclavicular nerve in conventional open plating. We investigated whether the use of minimally invasive plate osteosynthesis could reduce the incidence of post-operative numbness and improve patients' satisfaction compared to open plating. METHODS: Between August 2012 and October 2015, 73 patients with acute clavicle shaft fracture (Robinson classification 2A2-2B2) were treated with plate fixation at our institution...

Several conditions related to the intrauterine environment are associated with neuropsychiatric conditions in later life. In humans, approximately 2% of infants are exposed to perinatal hypoxia-ischemia or prolonged anoxic insult, a condition to which very low birth weight preterm infants exhibit the highest susceptibility. Analyses of postmortem tissue link some presentations of these conditions to changes in GABA pathway functionality in the brains of affected subjects. Using animal models of early-life hypoxia-ischemia, losses of particular interneuron populations were reported...

Avulsion fractures of the tibial eminence, although generally a rare injury pattern, are more common in children and adolescents than in adults. Many open and arthroscopic techniques are available with variable degrees of satisfying results and incidence of complications and adverse effects. Arthroscopic fixation appeared to improve the functional outcomes with fewer complications than the open fixation. New techniques were reported using commercially available suspension sling devices for the acromioclavicular joint that offers an easy and rapid method of fixation...

BACKGROUND: Patients with diabetes often develop diabetic peripheral neuropathy, which is a distal symmetric polyneuropathy, so foot function on the non-amputated side is expected to affect gait in vascular trans-tibial amputees. However, there is little information on the kinematics and kinetics of gait or the effects of diabetic peripheral neuropathy in vascular trans-tibial amputees. This study aimed to clarify these effects, including the biomechanics of the ankle on the non-amputated side...

The neural crest is induced at the edge between the neural plate and the nonneural ectoderm, in an area called the neural (plate) border, during gastrulation and neurulation. In recent years, many studies have explored how this domain is patterned, and how the neural crest is induced within this territory, that also participates to the prospective dorsal neural tube, the dorsalmost nonneural ectoderm, as well as placode derivatives in the anterior area. This review highlights the tissue interactions, the cell-cell signaling and the molecular mechanisms involved in this dynamic spatiotemporal patterning, resulting in the induction of the premigratory neural crest...

INTRODUCTION: Biomechanical studies have compared fixation methods in transverse acetabular fractures, yet there is not enough clinical data to suggest an optimal fixation method. The aim of this randomized controlled trail was to compare fracture stability in posterior plating alone versus posterior plating and anterior column lag-screw fixation in treatment of transverse and transverse with posterior wall acetabular fractures. METHODS: Thirty patients were randomized to one of two groups, either posterior fixation alone (single column group), or posterior plating and anterior fixation with percutaneous anterior column screw (double column group)...
