Abstract
Osteosynthesis constructs for treating bone fractures and bone screws for use in such systems are disclosed. The bone screws include a threaded front section configured for engagement with cortical bone, a threaded mid-section and an unthreaded neck section configured for limited movement within the near cortex of the bone. Osteosynthesis constructs of the type disclosed promote secondary healing by allowing for substantially parallel motion at the near and far cortex within the effective motion range for callus formation.
