Treatment of a tibial bone defect with a motorized intramedullary bone transport nail: A case review with 32 months follow up.

Nowadays, massive segmental bone defects represent a surgical challenge for trauma surgeons. Most of these injuries appear in the context of high-energy trauma, not only significantly affecting the bones, but also involving severe injuries of the adjacent soft tissues. For these reasons, their treatment requires complex reconstruction surgeries. There are multiple techniques to treat bone defects, bone transport being one of the most widely used. Historically, external fixators (monolateral and circular) have been and still are the gold standard for performing this technique, although they are not exempt from complications. By means of specific intramedullary nails for bone transport, it is possible to minimize the complications of external fixation, allowing large tibial bone defects to be treated through distraction osteogenesis (all-internal system), which is favoured by early weight bearing.
