Osteosynthesis Testing

Osteosynthesis is used to treat open bone fractures with concomitant injury to the skin or soft tissue. It is also the preferred form of treatment for bone fractures with multiple fragments, bone fractures on the leg and bone fractures in patients with osteoporosis.

STEMart performs a wide range of mechanical properties testing for various of osteosynthesis such as screw, plate, staple, gliding nail, wire and cable to characterize their lifespan and durability.
