STUDY DESIGN: Retrospective chart review. OBJECTIVE: The study purpose was to examine the feasibility of acute (<24 hours) and hyper-acute (<8 hours) treatment of thoracolumbar burst fractures to maintain or improve spinal injury scores. SUMMARY OF BACKGROUND DATA: Historically, treatment of spinal burst fractures within 24 hours from injury was considered an "acute" treatment timeframe. Patient polytrauma triage, multiple surgical specialty and hospital resource coordination affect time to treatment...

The development of reliable biomedical devices demands the use of an integrated manufacturing protocol with comprehensive understanding of prototype characterization in terms of 3D microstructural analysis along with biocompatibility. While addressing these issues for ZrO2 (3mol% Y2O3 stabilized)-toughened Al2O3-based femoral head prototypes, the present work reports a unique fabrication protocol involving a sequence of uniaxial compaction followed by pre-sintering, machining, final sintering and polishing to ensure dimensional tolerance with respect to the design of patient-specific femoral head...

Surgical management of thoraco-lumbar spine fracture in pregnancy has specific concerns during surgery like positioning, approach, and radiation exposure to fetus. We report a case of burst fracture of 12th thoracic vertebrae with paraplegia in a young female with 26 weeks of gestation. Surgery was performed in prone position on a Toronto frame. This report also discusses the management of thoraco-lumbar spine fracture in pregnancy with review of literature.

Hoverboards burst onto the scene with wide popularity only to be quickly deemed unsafe and banned in many arenas. We conducted a retrospective cohort study of 35 patients seen in our outpatient pediatric orthopedic office over a 1-year period. The mean age of injured patients was 11.14 years; 18 patients were male (51.4%), and 17 were female (48.5%). The highest number of injuries occurred in children 10 to 14 years old who had 57.1% of the injuries. There were a total of 31 fractures in 27 patients. Most of the fractures were in the upper extremities (93...

BACKGROUND: Jefferson's fracture, first described in 1927, represents a bursting fracture of the C1 ring with lateral displacement of the lateral masses. It has been determined that if the total lateral mass displacement (LMD) exceeds 6.9 mm, there is high likelihood of transverse atlantal ligament (TAL) rupture, and if LMD is less than 5.7 mm TAL injury is unlikely. Several recent radiographic studies have questioned the accuracy and validity of the "rule of Spence" and it lacks biomechanical support...

In 2004, a 61-year-old male presented to a chiropractic clinic complaining of neck pain after hearing a 'crunch' when getting out of bed that morning. The initial history intake and physical examination identified no red flags or indications for the patient's pain, with the exception of traction being pain-provoking. Conventional radiographs were ordered, which identified a pathological burst fracture of the fourth cervical vertebra. This Imaging Case Review (ICR) is to provide clinicians with a follow-up to the patient's care and current state...

RATIONALE: Burst fractures in thoracolumbar and lumbar spine typically occur from severe trauma, which may result in cauda equina herniation (CEH). In this study, we attempted to document the incidence and evaluate the sequelae of CEH that were found during decompression and fusion surgery for patients with burst fractures. PATIENT CONCERNS: A total of 416 patients were enrolled in this study. DIAGNOSES: The patients had been operated on through an anterior or posterior approach for treatments of thoracolumbar and lumbar burst fractures at our department between June 1, 2008 and June 1, 2011...

BACKGROUND: Thoracolumbar burst fractures (TBFs) are often followed by bilateral pedicle screw fixation (BPSF) at the level of fracture using posterior short-segment pedicle instrumentation (SSPI). There has been increasing support for unilateral pedicle screw fixation (UPSF) in an attempt to reduce complications and costs. The aim of this study was to compare the clinical and radiologic results of UPSF versus BPSF at the level of fracture using SSPI in the treatment of severe TBFs. METHODS: The records of 42 consecutive patients with severe TBFs who underwent SSPI were divided into 2 groups according to the number of screws in the fracture level, including 20 patients (five screws) in UPSF group and 22 patients (six screws) in BPSF...

Among the cues affecting cells behaviour, mechanical stimuli are known to have a key role in tissue formation and mineralization of bone cells. While soft scaffolds are better at mimicking the extracellular environment, they cannot withstand the high loads required to be efficient substitutes for bone in vivo. We propose a 3D hybrid scaffold combining the load-bearing capabilities of polycaprolactone (PCL) and the ECM-like chemistry of collagen gel to support the dynamic mechanical differentiation of human embryonic mesodermal progenitor cells (hES-MPs)...

A chemiluminescent mechanophore, bis(adamantyl-1,2-dioxetane), is used to investigate the covalent bond scission resulting from the sorption of chloroform by glassy poly(methyl methacrylate) (PMMA) networks. Bis(adamantyl)-1,2-dioxetane units incorporated as cross-linkers underwent mechanoluminescent scission, demonstrating that solvent ingress caused covalent bond scission. At higher cross-linking densities, the light emission took the form of hundreds of discrete bursts, widely varying in intensity, with each burst composed of 10(7)-10(9) photons...

Clinical classification of an injury has traditionally involved medical imaging, patient history, and physical examination. The pathogenesis or process of injury has been viewed as a crucial component to estimating fracture stability and direct treatment. However, injury classification systems generally exclude pathogenesis and injury mechanisms because these components are often difficult to elucidate. Furthermore, the development of bone damage relative to the mechanical response is difficult to quantify, which limits the ability to define injury and develop injury criteria...
