The number of rib fractures has been reported to correlate with mortality after blunt chest trauma. These reports, however, predate routine truncal helical computed tomographic (CT) scanning and their conclusions are based on data derived from plain chest radiographs (CXR). CT scan provides better anatomic definition of chest injuries than plain CXR, and we hypothesized CT evaluation of rib fracture number and patterns would provide a better prediction of respiratory failure and mortality after chest injury than the data derived from the initial CXR. ⋯ Rib fracture mortality was lower than that in the previously published studies and is likely reflect the increased sensitivity of CT scan in diagnosing rib fractures. Screening CXRs miss rib fractures more than 50% of the time. Radiology reports are often not sufficiently descriptive or are incomplete with respect to the number and location fracture and reliance on these data will lead to erroneous conclusions. Using CT scanning, only the finding of rib fractures in multiple locations was associated with increased incidence of respiratory failure. In contrast, the presence of any parenchymal injury or visible rib fracture on the screening CXR significantly increases the risk for subsequent pulmonary morbidity (odds ratio, 3.8; CI95, 2.2-6.6). Although truncal CT scanning markedly improved the diagnosis and delineation of rib fractures, the screening CXR was a better predictor of subsequent pulmonary morbidity and mortality.

To compare the stability of a novel, nonspanning external fixator with a standard volar locked plate for treatment of unstable distal radius fractures. ⋯ This study demonstrated no significant difference in the mechanical stiffness of the CPX nonspanning external fixator and volar locked plate in a cadaveric fracture model. Both constructs appear to be biomechanically equivalent in this experimental model; however, this is only one factor in the choice of fixation device for the management of unstable distal radius fractures.

Some recent studies have suggested that certain types of orthopedic trauma result in ongoing disability and that factors other than injury severity or location may influence outcome. This study aimed to evaluate outcome 12 months and 2 years after severe orthopedic trauma, as measured on the Short Form (SF)-36 Health Survey, relative to a control group, to examine change over time and to examine which demographic, injury-related and psychological factors are associated with persisting disability. ⋯ This study has highlighted pain and PTSD symptoms as frequent and disabling factors after othropedic trauma. There is clearly a need to focus on alleviating these problems as part of the rehabilitation process.

Serum albumin level is correlated with outcome in various clinical situations. Albumin has multiple physiologic properties that could be beneficial in brain injury. The Lund therapy for elevated intracranial pressure uses albumin as part of its protocol and demonstrates favorable outcome. We sought to find out if albumin is associated with outcome after traumatic brain injury to justify conducting a randomized trial. ⋯ Serum albumin level seems to be an independent predictor of poor outcome. The model also identified classic predictors of poor outcome that tends to strengthen its adequacy. Because albumin level is the only modifiable factor influencing outcome, it seems justified to carry out a randomized trial of the use of albumin in the treatment of brain injury.
