Randomized Controlled Trial Comparative Study Clinical Trial
[Differences between anteroposterior and posterior spondylodesis in clinical scores].
The present study on spondylitis patients was carried out to compare prospectively results of clinical scores of patients treated with anteroposterior or anterior spondylodesis. A total of 22 patients with spondylitis were enrolled in the randomized trial to undergo an operation with anteroposterior or posterior spondylodesis. For quality of life adjustment, the SF-36 health survey was applied. ⋯ No statistical difference was found between the two groups at any time. The less invasive nature of anterior spondylodesis could be responsible for that result. Anterior spondylodesis should used if possible and deemed adequate because it causes less discomfort.

Primary malignant neoplasms of the bone are rare. One of the most common bone tumors is osteosarcoma, most often localized in the metaphysis of adolescent long bones. ⋯ Osteosarcoma patients from Germany, Austria, and Switzerland are treated by neoadjuvant chemotherapy combined with complete surgical excision according to the Cooperative Osteosarcoma Study Group (COSS). Based on a review of the literature, diagnosis, treatment, and complications of two cases of sacrum osteosarcoma are introduced.

The aim of this study was to evaluate the costs involved in treating severely injured patients at the clinic differentiated by several characteristics (injury, age), sectors (emergency room, surgery, intensive and normal care), and kinds of costs (fixed costs, variable costs) and to determine influencing factors regarding costs based on the register of the DGU (Deutsche Gesellschaft für Unfallchirurgie). All patients were taken into account who had an injury severity score (ISS) of at least 16. On this basis costs of 3702 patients were analyzed. ⋯ Due to the high portion of fixed costs, the overall costs strongly depend on the capacity utilization and less on hospital stay. That is why it may be necessary in the future to create centers for trauma care to maintain economic efficiency for treatment of these patients. Besides large differences of costs within closely defined groups of patients, hospitals carry a high economic risk so that a more complex reimbursement system should be discussed than implemented by the German DRGs.
