Finite element simulation of three surgical treatments of distal radius intra-articular fracture

Distal radius fractures are the most common injuries, with an estimate overall crude incidence of 36.6/10,000 person-year in women and 8.9/10,000 person years in men. Assuming a continuous rise in the incidence of distal radius fractures with age, and based on the fact that older population continue...
