Comparative Study[Primary hip- and knee arthroplasty--comparison of the actual costs with the Australian diagnosis related groups (DRG)-].
With the introduction of the Australian DRG system in Germany the question arises which current procedures remain reasonable in cost. The present study compares the actual costs with the expected DRG reimbursement. ⋯ To cover the current costs for patients free of complications, an enormous reduction of the length of stay is required. Otherwise complicated cases may result in a loss of quality or selection of patients. The present cost analysis outlines a guideline for an individual calculation and assessment of the necessary DRG reimbursement.

Lumbar disc herniation is rare in adolescents and often misread. The difference of etiology, symptoms and therapy in comparison to adults were investigated and the long-term outcome of conservative and surgically treatment evaluated. ⋯ The etiology of lumbal disc herniations in adolescents has a multifactoral basis. Conservative treatment should be pursued as a mainstay of treatment. Only if conservative treatment fails, surgical treatment should be considered.

[Prognostic factors for avascular necrosis following talar fractures].
We performed an investigation of factors for avascular necroses after talus fracture and on the reliability of the Hawkins Sign. ⋯ The Hawkins Sign proved to be a relatively reliable sign for vitality of the talus after fracture. Risk for avascular necrosis increases according to the degree of fracture dislocation.

[Technique and results of monosegmental transpedicular subtraction osteotomy in patients with ankylosing spondylitis and fixed kyphotic deformity of the spine].
The posterior extension osteotomy leads to a lengthening of the anterior column, which is associated with neurological complications and the risk of injuring retroperitoneal structures. Especially in high-grade syndesmophytosis the results are dissatisfactory. In this study we report on the results of an alternative procedure named the transpedicular subtraction osteotomy. ⋯ With the transpedicular subtraction osteotomy fixed kyphotic deformities of the spine in patients with ankylosing spondylitis can be corrected produce safely. The level of osteotomy is discussed and should depend upon the apex of kyphosis.
