A Novel Technique for Creating an Articulating Cement Spacer for Ankle Prosthetic Joint Infections.

Total ankle arthroplasty has been increasing as a treatment for end-stage ankle arthritis. With this increase, the incidence of total ankle prosthetic infections will also increase. Treatment of these infections depends on the duration of symptoms and whether the infection is acute or chronic in presentation.

Comparison between suprapatellar and parapatellar approaches for intramedullary nailing of the tibia. Cadaveric study.

Unlabelled: Intramedullary nailing is one viable option for treating fractures of the tibia with a short, proximal segment. For a procedure being carried out with the knee in a semi-extended position, either a suprapatellar or parapatellar approach may be used. The objective of this study is to demonstrate whether the entry point for tibia nails is obtainable through suprapatellar or parapatellar approaches and to evaluate the most frequent injuries of the knee with these two approaches.

Antibiotic-like actions of vitamin D.

Vitamin D is a secosteroid hormone that has expanding importance for a healthy lifestyle and disease prevention. A multitude of studies have highlighted that vitamin D acts not only in bone and calcium homeostasis but is critically important for human immunity. The discovery that the storage form of vitamin D (25-hydroxyvitamin D3) can be locally converted to the active form (1,25-hydroxyvitamin D3) in immune cells, epithelial cells and numerous other non-renal tissues highlights the importance of maintaining sufficient stores.
