Multicenter, retrospective chart analysis was performed using data housed in the trauma registries of 2 independent American College of Surgeons verified, Level I Trauma centers. The trauma registries were queried for all cases of penetrating cervical trauma. Abstracted data included age, sex, race, mechanism of injury, Glasgow Coma Scale (GCS) level on arrival, neurologic findings on arrival, zone of injury, associated injuries, imaging studies and results, operations performed, neurologic sequelae, disposition from the hospital and the presence or absence of neurologic injury, cervical spine fracture, and cervical spine immobilization. ⋯ Cervical spine immobilization does not appear to prevent progression of neurologic injury in cases of penetrating cervical trauma. Comorbid penetrating injuries may be negatively impacted by prehospital cervical spine immobilization.

Case Report. ⋯ Neoplasm and infection were excluded. Careful reassessment alerted to the diagnosis of undifferentiated spondyloarthropathy. Solid arthrodesis and pain relief could be obtained by surgery together with medical control of the disease.

Clinical prospective cohort study in academic tertiary setting. ⋯ No significant changes in spinal cord function (to better or worse) were found in the current series after indirect spinal cord decompression through a posterior approach in patients with mild or no neurologic deficits. Further studies with larger series of patients presenting severe neurologic deficits are necessary to better establish these findings.

A finite element (FE) model of the human neck was used to study the distribution of neck muscle loads during multidirectional impacts. The computed load distributions were compared to experimental electromyography (EMG) recordings. ⋯ The passive muscle forces, strains, and energies computed using a continuum FE model of the cervical musculature distinguished between impact directions and peak accelerations, and on the basis of prior studies, isolated the most important muscles for each direction.

Retrospective case series. ⋯ Intralesional resection should be avoided as it is associated with a higher LR rate and worse survival. Rectus abdominus flaps ought to be considered as they lower the wound complication rate. Sacral resection is associated with significant morbidity.
