Case Reports
[Fatal soft tissue infections after arthroscopy of the knee joint. A diagnostic or therapeutic problem?].
After detection of a bacterial infection of the joint, an absolute indication for intervention is given. Systemic antibiotic drug therapy is indicated and drainage of the joint has to be performed immediately. The following therapeutic algorithm regimen is a proven remedy in treating pyoarthrosis of the knee joint: During the initial period, the infection can be controlled by arthroscopic irrigation and systemic antibiotic therapy. ⋯ If open joint revision including synovectomy is not performed or is performed too late, there will be a threat of irreversible damage of the afflicted joint up to septic spread endangering the patient's life. We report on two patients suffering from generalized sepsis resulting in death after delayed therapy for knee joint infection. Regarding the presented cases, it can be concluded that indication to early surgical joint debridement including open synovectomy of the knee is still rarely seen after development of pyoarthritis.

Comparative Study Clinical Trial
[Stable and unstable pertrochanteric femoral fractures. Differentiated indications for the dynamic hip screw].
The aim of all surgical procedures in the treatment of trochanteric fractures in elderly and even geriatric patients is achievement of initial stability. We examined in a clinical trial whether primary stability was achieved in all types of trochanteric fractures following osteosynthesis with the Dynamic Hip Screw (DHS). From 1994 to 1996, 122 patients with trochanteric fractures had osteosynthesis by dynamic hip screw. ⋯ Assessment of the functional outcome according to THRS showed a significant deterioration of 20 points in 71% of all patients compared with the preoperative score. The results show that dynamic hip screw osteosynthesis in instable trochanteric fractures is associated to a higher incidence of complications. While the dynamic hip screw still represents the standard implant in stable fractures of the trochanteric region, being aware of improved intramedullary implants regarding biomechanical features and surgical technique, the results justify to critical consider the use of DHS for osteosynthesis in instable fractures of the trochanteric region.

Case Reports Comparative Study
[Ventilation in prone position in a 5-year-old child after multiple trauma. Effective treatment of persistent atelectasis].
We report on the ventilation in prone position in a 5-year-old traumatized child with severe thoracic and abdominal injuries (lung contusion, rib fractures, rupture of liver and spleen). Under continuous analgesic sedation, the young patient was ventilated in prone position for 6 h, since acute lung injury and atelectasis persisted despite various therapeutic measures (artificial ventilation in the pressure controlled mode, fiberoptic bronchoscopy, reexpansion maneuver). After initiation of the prone position, we observed a rapid increase in arterial oxygenation, which persisted in the following period. ⋯ After cessation of analgesic sedation, the extubation was performed 2 days later. Furthermore, we found no side effects of the prone position on the injured abdomen, and the liver function improved rapidly. Although there is a lack of experience with ventilation in prone position in pediatric intensive care, our report might be a recommendation for the indication of this technique in children.

Comparative Study
[Ultrasound characterization of burn scars in children].
So far, little is known about the acoustic phenomena of high-frequency sonography for the assessment of healing processes in thermal wounds. However, ex vivo investigations have shown clear age-dependent differences in the rate of sound propagation in thermal scars compared to healthy skin. In order to answer the question of whether measurable acoustic characteristics of burn or scald scars can be classified in a way which corresponds to the clinical severity of the injuries, age of scar or type of treatment, 92 thermal scars, with an average scar age of 3.1 years, in 55 children were investigated with regard to corium thickness and echogenicity. ⋯ The comparison of different therapeutic strategies showed no therapeutic effect either for compression or for the application of silicone gel sheets. In contrast, a decrease in scar thickness and a loosening of scar structure could be seen after early application of a sterile, silicone-covered polyamide net bandage. The 20-MHz-Sonography is a suitable non-invasive procedure for the characterisation of burn scars.
