When patients with gunshot injuries are medically treated, it is also important to examine the wound itself to achieve further information concerning the distance and direction from where the bullet was fired. Besides that, it must be remembered that the bullet does not necessarily penetrate the target in a linear direction, but there can be various curves and angles in the bullet channel and subsequently adjacent organs injured.

Intraoperative ultrasonography is recommended for operations on the thoracolumbar spine to complement the information provided by standard X-ray, intensifier screen or myelography. There are no unanimates opinions concerning the impaction or exeresis of these fragments. The aim of this study was to show the advantages of intraoperative ultrasonography for anatomic determination and control of the maneuvers used. ⋯ The tilting before the impaction and the state of the overlying intervertebral disk represent essential factors for failures. Ultrasonography is better than intraoperative myelography. Nevertheless, it still needs to be complemented by intraoperative profile X-rays and a very precise preoperative CT scan of the intervertebral disk lesions analysis of complicated cases (fragments with residual pedicular attachments--type A 3.1.2.; T-like fractures--type A 3.2.1.).

Numerous epidemiological studies about multiple trauma patients do not include an analysis of patients under the age of 18. To study this, the data of 682 patients with multiple traumata, treated between 1981 and 1991 at Hannover Medical School, Germany, were retrospectively analyzed. The patients were divided into four age-related groups: preschool age (< 6 years), school age (< 13 years), teenagers (< 18 years) and adults (> or = 18 years). ⋯ Spinal cord injuries, especially injuries to the neck, also showed a high risk of death. Children younger than 6 years had the most severe head injuries. Safety improvements for children in cars, helmet usage on bicycles and early training in traffic safety for children might decrease the lethality in this group of trauma patients.

Pseudoarthrosis and cubitus valgus as main complications following displaced fractures of the radial condyle in children can be prevented by open reduction and fixation by K wires. However, delayed union and stimulation of the radial physis with condylar overgrowth and varisation of the elbow as well as fishtail deformities of the distal end of the humerus are reported nevertheless. To prevent those growth disturbances all primary and secondary (4-day X-ray control) displaced fractures of the radial condyle, i.e. those with a central gap of more than 2 mm, were prospectively treated by open reduction and osteosynthesis with a metaphyseal lag screw beginning 1974. Sixty-six patients (41 boys, 25 girls) with an average follow-up of 10 years (2-22 years) sustained 28 primary and 6 secondary displaced fractures. In 5 cases a K wire fixation was performed in view of the smallness of the fragment. Two children with conservative treatment following overlooked displaced fractures showed condylar overgrowth and varisation of the elbow. Screw osteosynthesis led to symmetric elbow angles and function in all cases, whereas fishtail deformities could be observed in 8 of 27 children, probably as a consequence of the remaining central fracture instability. ⋯ Open reduction and osteosynthesis with a metaphyseal lag screw prevents condylar overgrowth in displaced fractures of the radial condyle by guaranteeing fracture healing in anatomic position within 3-4 weeks. However, fishtail deformity can not be prevented by metaphyseal compression only.

Blunt chest trauma is the leading cause of thoracic injuries in Germany, penetrating chest injuries are rare. Hereby, single or multiple rib fractures, hemato-pneumothorax and pulmonary contusion represent the most common injuries. The early management of thoracic injuries consists of detection and sufficient therapy of acute life threatening situations like tension pneumothorax, acute respiratory insufficiency or severe intrathoracic bleeding. ⋯ Early intubation and PEEP-ventilation, alternate prone and supine positioning of multiple injured patients with lung contusion and differentiated concepts of volume- and catecholamine therapy represent the basic therapeutic principles. Additionally, the entire early trauma management of multiple injured patients must focus on the presence of pulmonary contusion. Every additional burden on their pulmonary microvascular system like microembolisation during femoral nailing, the trauma burden of extended surgery or mediator release in septic states may cause rapid decompensation and organ failure and therefore, has to be avoided.
