An intramedullary nail found in the left knee of a mummified Egyptian man. The oldest intramedullary nail was found in the left knee of a mummy named Usermontu, the remains of an Egyptian man from more than 3,500 years ago. Researchers believe the pin was inserted after the man's death, but before his burial. [4]
Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [1] especially in the femur and tibial bones, but can also occur genetically at birth.
For femoral shaft fractures, reduction and intramedullary nailing is currently recommended. [14] The bone is re-aligned, then a metal rod is placed into the femoral bone marrow, and secured with nails at either end. This method offers less exposure, a 98–99% union rate, lower infection rates (1–2%) and less muscular scarring. [14] [15] [17]
Unreamed intramedullary nailing is advantageous because it has a lower incidence of superficial infection and malunion compared to external fixation. [24] However, unreamed intramedullary nailing can result in high rates of hardware failure if a person's weight bearing after surgery is not closely controlled. [24]
Küntscher first performed the process using the nail in November 1939 at the University Department of Surgery in Kiel. He first presented 12 cases of intramedullary fixation with rods at a surgical meeting in Berlin 03/18/40 and was met with general disapproval for using surgery for fractures [ 1 ] The German military initially disapproved of ...

After introducing medically assisted treatment in 2013, Seppala saw Hazelden’s dropout rate for opiate addicts in the new revamped program drop dramatically. Current data, which covers between January 1, 2013 and July 1, 2014, shows a dropout rate of 7.5 percent compared with the rate of 22 percent for the opioid addicts not in the program.
Implant that has been used for fixation of a broken wrist. Closed reduction internal fixation (CRIF) is reduction without any open surgery, followed by internal fixation. It appears to be an acceptable alternative in unstable distressed lateral condylar fractures of the humerus in children, but if fracture displacement after closed reduction exceeds 2 mm, open reduction and internal fixation ...
