Abstract The aim of this is to evaluate the biomechanical performance double-level semirigid pedicle screw fixation and artificial intervertebral disc replacement in lumbar spine. Ti6Al4V CFR-PEEK material are used for replacement. In present study, carried out between L3-L4-L5 regions under application moment 6,8,10 Nm range motion compared during flexion, extension, right-left lateral bending...

Paravertebral muscles play an important role in the development of deformities and degenerative diseases spine. The impact posterior arthrodesis ileosacral articulation (sacrum-iliac joint) on morphological characteristics m. sacrocaudalis (coccygeus) dorsalis lateralis mongrel dogs was studied animal experiments. Titanium cages were used, followed by stabilization with external fixation device...

Objective: To examine the validity of using cadaveric spines of deer or boars for biomechanical experiments as substitutes for the cadaveric spine of humans. Materials and Methods: Five specimens of the L3-4 functional spinal unit of human cadavers, mature deer and mature boars were prepared according to 3 models: 1) normal model, 2) injured model and 3) pedicle screw fixation model and they we...

INTRODUCTION Injuries around shoulder and clavicle are quite common. Injuries involving lateral end of clavicle involving acromioclavicular joints are commoner injuries. In this rare injury, we report about a case involving clavicle and scapular spine fracture with acromioclavicular disruption which has never been described in English literature as per our knowledge. CASE REPORT A patient wit...

Specific and non-specific infections of the spine are rare. Due to their potential for severe instabilities, deformities and the impairment of neurological structures, the treatment is often prolonged and needs an interdisciplinary management. The clinical presentation is uncharacteristic, therefore diagnosis is often delayed. There are no prospective randomized studies for therapy recommendati...

BACKGROUND Our group developed a protocol, entitled Early Appropriate Care (EAC), to determine timing of definitive fracture fixation based on presence and severity of metabolic acidosis. We hypothesized that utilization of EAC would result in fewer complications than a historical cohort and that EAC patients with definitive fixation within 36 h would have fewer complications than those treated...
