Multicenter Study Observational Study
Physiologic, demographic and mechanistic factors predicting New Injury Severity Score (NISS) in motor vehicle accident victims.
Current literature on motor vehicle accidents (MVAs) has few reports regarding field factors that predict the degree of injury. Also, studies of mechanistic factors rarely consider concurrent predictive effects of on-scene patient physiology. The New Injury Severity Score (NISS) has previously been found to correlate with mortality, need for ICU admission, length of hospital stay, and functional recovery after trauma. To potentially increase future precision of trauma triage, we assessed how the NISS is associated with physiologic, demographic and mechanistic variables from the accident site. ⋯ This study in victims of MVAs demonstrated that injury severity (NISS) was concurrently and independently predicted by poor pre-hospital physiologic status, increasing age and female gender, and several mechanistic measures of localised and generalised trauma energy. Our findings underscore the need for precise information from the site of trauma, to reduce undertriage, target diagnostic efforts, and anticipate need for high-level care and rehabilitative resources.

Winter sports have evolved from an upper class activity to a mass industry. Especially sledging regained popularity at the start of this century, with more and more winter sports resorts offering sledge runs. This study investigated the rates of sledging injuries over the last 13 years and analysed injury patterns specific for certain age groups, enabling us to make suggestions for preventive measures. ⋯ Mild head trauma was mainly found in very young sledgers, and injuries to the lower extremities were more frequent in adults. In accordance with the current literature, we suggest that sledging should be performed in designated, obstacle-free areas that are specially prepared, and that children should always be supervised by adults. The effect of routine use of helmets and other protective devices needs further evaluation, but it seems evident that these should be obligatory on official runs.

Comparative Study
Comparative study of phrenic nerve transfers with and without nerve graft for elbow flexion after global brachial plexus injury.
Nerve transfer is a valuable surgical technique in peripheral nerve reconstruction, especially in brachial plexus injuries. Phrenic nerve transfer for elbow flexion was proved to be one of the optimal procedures in the treatment of brachial plexus injuries in the study of Gu et al. ⋯ Phrenic nerve transfers with and without nerve graft for elbow flexion after brachial plexus injury had no significant difference for biceps reinnervation according to MRC grading and EMG. A delay of the surgery after the 4 months might imply a bad prognosis for the recovery of the function.

We hypothesised that in blunt trauma patients with haemodynamic instability and haemoperitoneum on hospital admission, the haemorrhagic source may not be confined to the peritoneum. The purpose of this study was to describe the incidence and location of bleeding source in this population. ⋯ Haemoperitoneum was associated with PAB in only 52% of hypotensive blunt trauma patients and 63% of bleeding patients. In contrast, 59% of bleeding patients had at least one EPAB. The screening of a haemoperitoneum as a marker of active haemorrhagic source may be confusing and lead to misdiagnosis and inappropriate strategy. Clinician should exclude carefully the presence of any EPAB explaining haemorrhagic shock, before to decide haemostatic treatment.

To address midfoot instability of Charcot disease a promising intramedullary implant has recently been developed to allow for an arthrodesis of the bones of the medial foot column in an anatomic position. We report on a group of patients with Charcot arthropathy and instability at the midfoot where the Midfoot Fusion Bolt had been employed as an implant for the reconstruction of the collapsed medial foot column. ⋯ Medial column support in midfoot instability of Charcot arthropathy with a single intramedullary rod does not provide enough stability to achieve osseous fusion. MFB loosening was associated with deep infection in a majority of our cases. To prevent early loosening of the intramedullary rod and to increase rotational stability, additional implants as angular stable plates are needed at the medial column and eventually an additional stabilisation of the lateral foot column where manifest instability exists at the time of primary surgical intervention.
