Analgesia is one of the physician's genuine challenges. Pain makes the patient suffering and leads to unfavourable somatic effects as well, which may have negative outcome effects. Sufficient perioperative analgesia depends on well defined organizational conditions. ⋯ Special syringe pumps allow a patient controlled analgesia (PCA) under fixed conditions. Regional anaesthesia via catheter is powerful as well and avoids systemic opioid side effects. In these cases as well, a continuous or patient controlled analgesia is possible.

Unstable pelvic ring injuries AO type C ("vertical shear") with a fractured sacrum are treated operatively in less than 50% of the cases (DGU pelvis study group). Furthermore, only 12% of these ORIF involve the sacrum bone itself. No specific technique has gained wide acceptance in treating transsacral instability. ⋯ This allowed immediate mobilization in all cases. The radiologic follow-up examination ( n=20) revealed a solid union in all patients. Complications focused on management of the soft tissue degloving injury (Morel-Lavalleé lesion), which needs special attention.

The goal of this study was to evaluate the accuracy of CT-based computer-assisted pedicle screw insertion in the thoracic spine in patients with fractures, metastases, and spondylodiscitis compared to a conventional technique. A total of 324 pedicle screws were inserted in the thoracic spines of 85 patients: 211 screws were placed using a CT-based optoelectronic navigation system assisted by an image intensifier and 113 screws were placed with a conventional technique. ⋯ Despite use of the navigation system, 1.9% of the computer-assisted screws perforated the pedicle wall by more than 4 mm. The additional use of the image intensifier helped to identify the correct vertebral body and avoided cranial or caudal pedicle wall perforations.

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.

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.
