Thirty years after its introduction in Germany, the benefits of the helicopter emergency medical service (HEMS) compared to ground ambulances (GA) still remain unclear. The aim of this study was to evaluate the influence of helicopter transport on rescue time and mortality based on the data of the German Trauma Registry. ⋯ Only minor differences in age and ISS were found between the groups. The time between the accident and arrival of the physician was longer in the HEMS group. The HEMS group also remained on the scene for longer, but had a higher rate of intervention. According to our analysis of the German Trauma Registry, patients with multiple injuries benefit from HEMS transportation.

In recent years, the use of expandable titanium cages for vertebral body replacement in the thoracolumbar spine has been well established for the treatment of tumors, unstable traumatic lesions, or posttraumatic deformity. Collapse of the implant into the vertebral body remains a point of concern. A biomechanical compression test was designed to assess implant subsidence for a newly developed prototype for vertebral body replacement in the thoracolumbar spine using human cadaveric lumbar vertebrae. The objective of this study was to compare the compressive performance of a new expandable cage with modified end-plate design with three commonly available expandable cages for vertebral body replacement. ⋯ The modified endplate design of the new prototype was found to improve its compressive performance under constrained uniaxial loading conditions at the implant-bone interface. The improved compressive behaviour of the new implant might help to reduce the risk of implant subsidence and collapse into the vertebral body in vivo.

The controversial situation relating to assessment and management of the traumatic head injury (THI) in children inspired us to study our own patient pool. The aims were to find a significant correlation between skull fracture or clinical symptom and intracranial lesion as well as to determine the importance of each radiological diagnostic method in the initial management of the pediatric THI. ⋯ A management plan for pediatric head and brain injury in the emergency room based on our own and published international results is introduced.

In polytraumatized patients severe joint injuries represent a special entity because their management is complex and lengthy. The surgeon must decide if limb salvage is indicated and which further surgical steps have to be instituted. The decision for amputation is based on the patient's general condition and the soft-tissue and neurovascular injury. ⋯ Priority is given to restoration of sufficient blood supply and soft tissue repair; the indication for fasciotomy covers a wide field. To avoid further compromise to soft tissue and perfusion, temporary joint and fracture stabilization is required. Definitive surgery has to be delayed until the 2 week period, starting between the fifth and tenth day after trauma.

The authors present the case of a 57-year-old man with polytrauma, who was injured in a train accident. Together with other injuries, he also sustained multiple comminuted fractures on the left half of the rib cage. ⋯ Extensive damage to the thoracic skeleton was treated by removal of the damaged tissues and replacement by the HI-TEX PARP NT implant. The presented procedure is being discussed as an alternative to metallic fixation in thoracic instability in cases of devastating injury or injury resulting in bone and tissue loss.
