Review Comparative Study
[Periprosthetic fractures: classification, management, therapy].
The incidence of periprosthetic fractures is increasing because of the increasing age and the rising number of joint replacements. Elderly patients are endangered because of a higher rate of co-morbidity such as osteoporosis or cardiovascular diseases. The treatment of periprosthetic fractures depends on these preconditions and has to solve the problem after an exact analysis of the fracture. ⋯ Intraoperative and postoperative periprosthetic fractures will be discussed with emphasis on classification and treatment. The aim has to be an early functional postoperative treatment with partial/full weight bearing in order to avoid postoperative complications. In discussing the scope of periprosthetic fractures, the site, incidence, treatment and outcome of periprosthetic fractures of the hip and knee will be outlined.

Comparative Study
[DRG reimbursement for multiple trauma patients -- a comparison with the comprehensive hospital costs using the German trauma registry].
The introduction of diagnosis related groups (DRG) will radically change the payment system for German hospitals. In 2002 the values for most DRG's were published for the german system (G-DRG). The polytrauma working group of the German Trauma Society developed a calculating algorithm to estimate the comprehensive hospital costs for every patient in the German trauma registry. The aim of this study was to compare these costs with the reimbursement according the the G-DRG's for a standardized population of polytrauma patients. ⋯ The comprehensive hospital costs for treating polytrauma patients are on average 12.893 euro higher than the reimbursement according the G-DRG's. For hospitals to be fully reimbursed G-DRG values have to be reconfigured according to the German health care system. Thus, inclusion criteria to specific G-DRG have to be changed and a specific G-DRG group for very severely injured patients needs to be established.

The orthopedic treatment is the first choice in shaft fractures of the humerus in children. Angulations of more than 10 degrees need reduction, in that case anesthesia should be used for surgical stabilization. The preferred method is the elastic-stable intramedullary nailing (ESIN). ⋯ In severe displaced fractures, reduction and stabilization by ESIN is recommended in patients over the age of 10 years. The method is even applicable to pathological fractures in juvenile bone cysts. In adolescents after the start of epiphyseal plate closure, angle-stable implants are an alternative.
