an intramedullary metal nail used for internal fixation of a fracture.
Etymology: Gerhard Küntscher, German surgeon, 1902-1972; AS, naegel
a stainless steel nail used in orthopedic surgery for the fixation of fractures of the long bones, especially the femur. Also called Küntscher intramedullary nail.
intramedullary nailA metal rod forced into the medullary cavity of long, weight-bearing bones (e.g., femur, tibia), which allows ambulation within weeks rather than months. Intramedullary nails have a cloverleaf appearance on cross-section and are made of titanium, which has a lower rate of mechanical failure and improved biocompatibility.
Persistent knee pain (present in 3/4 of patients), arthritis (1/3), and atrophy of the quadriceps and calf muscles (1/4).
Kuntscher nailA large, strong, stainless steel nail with a clover-leaf cross-section, used to maintain alignment in fractures of the shaft of the thigh bone (FEMUR) or TIBIA. The nail is hammered into the hollow canal of the bone. (Gerhard Kuntscher, 1902–72, German surgeon)
