A Modular Repository-based Infrastructure for Simulation Model Storage and Execution Support in the Context of Oncology and Medicine.

The plethora of available disease prediction models and the ongoing process of their application into clinical practice - following their clinical validation - have created new needs regarding their efficient handling and exploitation. Consolidation of software implementations, descriptive information, and supportive tools in a single place, offering persistent storage as well as proper management of execution results, is a priority, especially with respect to the needs of large healthcare providers. At the same time, modelers should be able to access these storage facilities under special rights, in order to upgrade and maintain their work.

High hip center technique using a biconical threaded Zweymüller cup in osteoarthritis secondary to congenital hip disease.

Background: The high hip center technique used for a deficient acetabulum is reconstruction of the hip at a high center of rotation. In the literature, there is no consensus regarding the value of this technique.

Questions/purposes: We investigated whether the new-generation biconical threaded Zweymüller cup fixed in a high nonanatomic position in patients with arthritis secondary to congenital hip disease experienced different rates of polyethylene wear and long-term survivorship when compared with anatomically positioned cups.

High tibial osteotomies: indications and techniques.

The rationale, definition, and techniques of high tibial osteotomies are discussed. The principle indication includes unicompartmental medial or varus knee gonarthrosis with a well-maintained range of motion. Preservation of bone stock and intraarticular structures and realignment during chondral resurfacing procedures are the major advantages of high tibial osteotomies.

Ankle arthrodesis using a tibio-calcaneal external fixator.

The results of open ankle arthrodesis in 23 patients with primary and secondary ankle-talar arthritis are presented. All patients were treated with open ankle arthrodesis using the Citieffe/CH-N external fixator with pins inserted in the tibia and the calcaneus. Union rate was 91% (21 patients) at an average of 13 weeks (range, 12-16 weeks).
