A study of degradable orthopedic implant: An insight in magnesium metal matrix composites.

Majority of the properties required for orthopedic implants operation are demonstrated by magnesium and its alloys, however the metal degrades rapidly in the body's environment. Therefore, a magnesium-based metal matrix composite capable of safely and gradually degrading in the body within the required healing time is required, thereby eliminating the need for a secondary surgery. In this study, three AZ31 Mg alloy samples with 50% reinforcement of Calcium Carbonate Powder, 25% reinforcement of CaCo, and no reinforcement (As-received) were developed via stir-casting technique.

The effect of plyometric training on peroneal latency.

Context: Peroneal reaction to sudden inversion has been determined to be too slow to overcome the joint motion. A focused plyometric training program may decrease the muscle's reaction time.

Objective: To determine the effect of a 6-wk plyometric training program on peroneus longus reaction time.
