Comparative Study
Skeletal traction versus external fixation in the initial temporization of femoral shaft fractures in severely injured patients.
: Damage control with external fixation (DC-EF) of femoral shaft fractures in polytrauma patients is becoming standard treatment in many trauma centers. However, skeletal traction (ST) has long been used in the temporization of fractures. The purpose of this study was to compare the major physiologic clinical outcomes of provisional ST with DC-EF of femoral shaft fractures in severely injured patients. ⋯ : DC-EF of femur fractures in severely injured patients offers no significant advantage in clinical outcomes compared with ST. Unless initially subjected to general anesthesia for life saving procedures, the use of ST as a temporization method remains a practical option.

Controlled Clinical Trial
Measuring tissue oxygen saturation via spectrometer in children.
: Near-infrared spectroscopy is a new noninvasive method of monitoring oxygen saturation at a tissue level. The purpose of this study was to evaluate new near-infrared tissue spectrometer InSpectra (Hutchinson Technology Inc.) in children and to determine preferable areas of the body to measure tissue oxygen saturation (StO2). ⋯ : Bicep and deltoid muscles are the most appropriate areas to measure StO2 using the 25-mm transducer in children of different ages. The use of near-infrared spectroscopy on the thenar eminence, which is usually used for measurement in adults, has varied results in children depending on the age, weight, and presence of fever.

: Intraoperative contouring of long bridging plates for stabilization of flail chest injuries is difficult and time consuming. This study implemented for the first time biometric parameters to derive anatomically contoured rib plates. These plates were tested on a range of cadaveric ribs to quantify plate fit and to extract a best-fit plating configuration. ⋯ : A small set of anatomic rib plates can minimize the need for intraoperative plate contouring for fixation of ribs 3-9. Anatomic rib plates can therefore reduce the time and complexity of flail chest stabilization and facilitate spanning of flail segments with long plates.

Controlled Clinical Trial
Cervical spine clearance in obtunded blunt trauma patients: a prospective study.
: An acceptable algorithm for clearance of the cervical spine (C-spine) in the obtunded trauma patient remains controversial. Undetected C-spine injuries of an unstable nature can have devastating consequences. This has led to reluctance toward C-spine clearance in these patients. ⋯ : Our results indicate that CT of the C-spine is highly sensitive in detecting the vast majority (99.75%) of clinically significant C-spine injuries. We recommend that CT be used as the sole modality to radiographically clear the C-spine in obtunded trauma patients and do not support the use of flexion-extension radiographs as an ancillary diagnostic method.

: Generations of clinicians have used the Baux score, defined as the sum of age in years and percent body burn, to predict percent mortality after trauma, but advances in burn care have rendered the predictions of this score too pessimistic. Additionally, this score does not include the effects of inhalation injury. ⋯ : Our proposed revised Baux score is simple enough for mental calculation, and its inverse logit transformation (provided with a calculator or nomogram) can provide precise predictions of mortality. Better predictions can be obtained using our more complex statistical model. Burn surgeons and nurses accustomed to using the original Baux score may welcome an updated version.
