Kind Code:

Abstract:
An osteosynthetic apparatus uses an intramedullary nail. The intramedullary nail is formed in a hollow shape and is provided with an outflow portion for outflow of a bone filling agent near the tip thereof. In the osteosynthetic apparatus, the intramedullary nail is provided with an insertion opening for insertion of a fixing nail in a base region thereof, the fixing nail is formed in a hollow shape and has an outflow portion for outflow of the bone filling agent near the tip thereof, and the fixing nail is inserted in the insertion opening and is fixed to the intramedullary nail. A fixing nail is of a curved shape and is rotatable in a state in which it is inserted in the fixing-nail insertion opening in the base region of the intramedullary nail. The osteosynthetic apparatus provides an enhanced fixing force of the intramedullary nail to a bone, particularly, to a bone being fragile because of osteoporosis or the like. The osteosynthetic apparatus does not have to use screws as fastening devices between the intramedullary nail and the bone, so as to reduce the invasion into the skin and soft tissue.
