Knee arthrodesis using a short locked intramedullary nail. A new technique.

This article reports on the use of a new intramedullary nail designed specifically for fixation of knee fusions. The nail is a short locked stainless steel nail that is inserted through a single anterior knee incision and uses an outrigger targeting rod to guide the insertion of the locking screws. The successful use of this technique is illustrated in two cases. The advantages of this nail compared with previously reported techniques of fixation for knee fusions are that the short locked nail avoids the second incision required for the insertion of long knee fusion nails, the bulkiness of the double plating technique in the relatively subcutaneous anterior knee area, and the difficulties inherent with the prolonged use of pins for external fixation.
