Comparative Study
An in-depth technical and medical investigation of facial injuries caused by car accidents.
Many studies have investigated the issue of facial injuries caused by car accidents, but only a few have addressed the technical and clinical aspects of such accidents and injuries in depth. The aim of this study was to identify risk factors and protective elements for facial injuries in car accidents. ⋯ Male sex and a high speed at the time of collision are significant risk factors for the occurrence of facial injuries. The security measurements evaluated in this study only exerted a protective influence at low speeds (below 40 km/h). This indicates a possible weakness of these security systems with regard to preventing facial injuries. Engineers could benefit from these findings and improve the efficiency of existing security measures and eventually help decrease the incidence of facial injuries.

Older adults enduring a polytrauma have an increased mortality risk. Apart from age, the role of other predisposing factors on mortality are mainly described for the total polytrauma population. This study aimed to describe the mortality pattern of older polytrauma patients, its associated risk factors, and the role and etiology of in-hospital complications. ⋯ Age is strongly associated with in-hospital mortality in polytraumatized elderly. Coagulopathy, acidosis, a low Glasgow coma score, presence of a large subdural hematoma and injury severity score were independently of age associated with an increased mortality. Patients older than 75 years showed a unique trimodal distribution of mortality with a late onset one week following the initial trauma. Elderly were more susceptible for fatal complications. Respiratory failure was the most prevalent severe and fatal complication. Aggressive monitoring and treatment of the pulmonary status is therefore of utmost importance.

In this retrospective study we have analyzed a consecutive series of patients affected by isolated radial head Mason III fractures and treated with bone resection or prosthesis. ⋯ According to our experience and to the most recent literature, we recommend prosthesis in patient younger than 50 y.o., high demanding or manual worker, while in other cases we think that radial head resection can be the treatment of choice.

Intramedullary nailing is a valuable treatment option for many types of fractures. Furthermore nailing is applicable for osteosynthesis following osteotomy in deformity correction. For intraoperative fine-tuning of alignment in intramedullary (IM) nailing procedures, a bending device for customization of IM nails under sterile conditions was developed. We have performed a retrospective clinical study to analyze and describe the technical requirements, indications and limitations for intraoperative customization of IM nails. ⋯ Intraoperative customization of intramedullary nails is a valuable technique for precise alignment control with IM nailing. With this technique, the benefits of IM nailing can be used for a wide range of indications, including deformity correction. The sterile bending device is safe and easy to handle. It is strong enough to bend all commercially available IM nails. Monofocal or linear bending in multiple planes is possible. However, when defining the site of bending, one must consider the removal of the implant in the future.

Tibiotalocalcaneal arthrodesis is commonly considered a salvage option for a variety of hindfoot disorders involving the ankle and subtalar joint mostly with concomitant deformity. Retrograde interlocking nailing represents one of the biomechanically most stable fixation modes after reduction of hindfoot geometry. The considerable complications, non-union and revision rates at a moderate outcome reported even with modern retrograde nails underscore the idea that the development of an optimized retrograde nail may be warranted. ⋯ On the basis of our results, which saw a high rate of successful fusion and patient satisfaction and where the hindfoot reduction was maintained until definite healing in the vast majority of cases, the novel circular arc nail represents a viable and safe option for tibiotalocalcaneal arthrodesis with a low complication rate.
