Comparative Study
Neurological, functional, and biomechanical characteristics after high-velocity behind armor blunt trauma of the spine.
Behind armor blunt trauma (BABT) describes a nonpenetrating injury to the organs of an individual wearing body armor. The aim of this study was to investigate the neurologic and functional changes that occur in the central nervous system after high-velocity BABT of the spine as well as its biomechanical characteristics. ⋯ The results from our animal model indicate that high-velocity BABT of the spine generates high pressure and acceleration in the spine, induces varying degrees of paralysis of hind limbs, and disturbs cerebral function. The neuronal degeneration caused by the pressure wave may be one of the important pathologic events involved in the development of trauma-related complications.

Continuous intercostal nerve blockade for rib fractures: ready for primetime?
Providing analgesia for patients with rib fractures continues to be a management challenge. The objective of this study was to examine our experience with the use of a continuous intercostal nerve block (CINB). Although this technique is being used, little data have been published documenting its use and efficacy. We hypothesized that a CINB would provide excellent analgesia, improve pulmonary function, and decrease length of stay (LOS). ⋯ Utilization of CINB significantly improved pulmonary function, pain control, and shortens LOS in patients with rib fractures.

Traumatic sternal fractures occur in approximately 3% to 8% of all blunt trauma patients. Most of these fractures are treated conservatively, but a small number require operative intervention. Only a few studies have reported operative fixation of sternal fractures, and no investigation to our knowledge has systematically reviewed the literature on this intervention. ⋯ Although the outcomes were generally positive, only one-half of the articles documented patient follow-up. In future studies, focus needs to be placed on long-term results and specific indications for surgery. The first step toward a standardized sternal fracture operative trial must be a prospective study of incidence and nonoperative long-term outcomes. It is likely that as the interest and demand for plate fixation increases, the demand for orthopedic involvement with sternal fractures will also increase.

Apnea (APN) and pneumothorax (PTX) are common immediately life-threatening conditions. Ultrasound is a portable tool that captures anatomy and physiology as digital information allowing it to be readily transferred by electronic means. Both APN and PTX are simply ruled out by visualizing respiratory motion at the visceral-parietal pleural interface known as lung sliding (LS), corroborated by either the M-mode or color-power Doppler depiction of LS. We thus assessed how economically and practically this information could be obtained remotely over a cellular network. ⋯ The emergent exclusion of APN-PTX can be immediately accomplished by a remote expert economically linked to almost any responder over cellular networks. Further work should explore the range of other physiologic functions and anatomy that could be so remotely assessed.

The treatment of interprosthetic femoral fractures is challenging because of several factors. Poor bone stock, advanced age, potential prosthetic instability, and limited fracture fixation options both proximally and distally can complicate standard femur fracture treatment procedures. The purpose of this report was to describe our experience treating interprosthetic femoral fractures, providing an emphasis on treatment principles and specific intraoperative management. ⋯ The principles for treatment of isolated periprosthetic fractures are useful to guide the fixation of interprosthetic fractures. Locked plating is an effective method for the treatment of interprosthetic femoral fractures. Bypassing the adjacent prosthesis by a minimum of two femoral diameters is a necessary technique to prevent a stress riser.
