- Males or females 17 years or older with confirmed closure of the tibial epiphyses,
with a closed fracture of the tibial diaphysis undergoing treatment with reamed locked
IM nailing procedure and the absence of an associated compartment syndrome or vascular
injury;

- Closed tibial fractures Types A, B & C (See OTA fracture classification) can be
included.

administration;

- Any other planned invasive or non invasive interventions intended to promote bone
healing of the tibial fracture under study are not allowed in the first 24 weeks after
treatment.
