Transfixation pin casting is a modified form of external skeletal fixation used to repair lower limb fractures in large animal patients.  Transfixation pins are placed proximal to the fracture and are incorporated into a cast that includes the foot.  Fiberglass cast material is most commonly used.  In this application, the cast becomes somewhat analogous to external bars of a fixation frame transferring loads through the foot to the pins above the fracture site – thus providing stability to the fracture.  IMEX® was the first company to produce transfixation pins specific to large animal application.

These pins along with related drill bits and taps are designed for lower limb application in large animal patients.
