Percutaneous cannulated screw fixation in the treatment of distal radius fractures.
The aim of this study was to determine the results of closed reduction and percutaneous fixation of distal radial fractures with standard 4.0-mm cannulated screw. ⋯ Cannulated screw fixation appears to be an effective means of allowing immediate range of motion of the wrist, resulting in a rapid and comfortable functional recovery while maintaining alignment to bone healing.

Wear patterns of tibiofemoral articulation in osteoarthritic knees: analysis and review of literature.
Osteoarthritis is a degenerative joint disease characterized by progressive erosion of the articular cartilage. The sites of erosion of articular cartilage have been reported, but no explanation for this particular pattern has previously been suggested. ⋯ In osteoarthritis of the knee joint, the middle third of both the femoral and tibial articular surfaces is most commonly involved in wears, followed by anteromedial and posterolateral compartments both for tibial and femoral surfaces. The wear patterns in the ACL-deficient knee changes due to altered loading characteristics.

Comparative StudyThe optimal carrier for BMP-2: a comparison of collagen versus fibrin matrix.
The aim of our study was to investigate in vitro and in a new in vivo rat model for impaired bone healing whether a low dose BMP-2 preparation in fibrin would be equivalent or better than the combination of collagen and a high dose of BMP-2 which is currently in clinical use. ⋯ We conclude that fibrin matrix is an excellent carrier for BMP-2 and that it provides equivalent results with a sevenfold lower dose of BMP-2 compared with ACS.
