Biomechanical Analysis of Intervertebral Cement Extravasation in Vertebral Motion Segments.

Kyphoplasty is a therapeutic option for pain relief in the setting of compression fractures. Cement extravasation into adjacent disks is a common occurrence. The biomechanical and clinical consequences of cement in the disks currently are unknown.

Changes in the care of patients with cervical spine fractures following health reform in Massachusetts.

Introduction: There is a substantial concern among spine surgeons that healthcare reform efforts will alter the processes through which spinal care is delivered and decrease overall quality. We used the Statewide Inpatient Dataset for Massachusetts to evaluate changes in hospital processes and quality of care for patients with cervical fractures following the implementation of health reform.

Methods: This was a pre-post retrospective analysis of patients (n=9,387) treated for cervical fractures in Massachusetts between 2003-2006 and 2008-2010.

Delayed presentation of pharyngeal erosion after anterior cervical discectomy and fusion.

Dysphagia after anterior cervical discectomy and fusion (ACDF) is common, with a prevalence ranging between 28% and 57% of cases. However, nearly all cases resolve spontaneously within 2 years, thus identifying patients who require more detailed or invasive work-up is a challenging task for clinicians. A review of literature reveals a paucity of case reports detailing work-up and successful management options.

Mortality, complication risk, and total charges after the treatment of epidural abscess.

Background Context: The treatment of epidural abscess is known to have a high rate of morbidity. Little is known regarding the risk factors for postoperative complications, mortality, and costs of care.

Purpose: To identify predictors of postsurgical morbidity and mortality, and total charges, associated with epidural abscess.

Acromial base fractures after reverse total shoulder arthroplasty: report of five cases.

Background: Most series of reverse total shoulder arthroplasty (rTSA) have reported acromial fractures, but they have not been shown to alter reported outcomes in most series. We present 5 patients with acromial base fractures where the entire deltoid origin was displaced from its anatomic location.

Materials And Methods: Five patients with acromial base fractures after rTSA were identified and evaluated for functional outcomes and pain relief as well as results of fracture treatment.

Naringenin inhibits neointimal hyperplasia following arterial reconstruction with interpositional vein graft.

Vessels respond to injury by a healing process that includes the development of neointima. Stenosis secondary to neointima formation is the main cause of failure following arterial reconstructions. Vessel wall homeostasis is regulated by proinflammatory cytokines that affect smooth muscle cell proliferation, growth, migration, and death.
