Cementless distal radius prosthesis 7115-29/17Le

After to the preoperative planning, ideally, a regional anesthetic is given and the patient is positioned in supine position with an arm support. After blood draining of the arm a pneumatic tourniquet is applied at the base of the arm. After to the preoperative planning, ideally, a regional anesthetic is given and the patient is positioned in supine position with an arm support. After blood draining of the arm a pneumatic tourniquet is applied at the base of the arm. The dorsal retinaculum of the extensor tendon is cut longitudinally on the ulnar side and raised en bloc to the radial side of the wrist The extensor tendons of the little finger, the extensor carpis radialis longus and brevis and the extensor pollicis longus are looped together. If necessary, Lister’s tubercle is removed and then the radiocarpal capsule of the joint is opened. The mediocarpal capsule remains intact. The cartilage and the subchondral bone of the radial epiphysis on the entire joint of the distal radius are removed; the sigmoid cavity is preserved An opening of the surface of the radius is carried out using an awl, directly in the center of the intramedullary canal. The opening point must be slightly dorsal and radial to the center of the articulating surface of the radial joint. The intramedullary nail is inserted with a handle through the opening point and pushed forward to the subchondral bone of the radius head. The intramedullary nail is inserted with a handle through the opening point and pushed forward to the subchondral bone of the radius head. A cannulated rasp is introduced over the intramedullary nail and, with the hammer, space is created for the radius implant.
