Cementless Distal Radius Prosthesis

Ideally, a regional anesthetic is administered following the preoperative planning, and the patient is placed in a supine position with an arm support. After the arm has been drained of blood, a pneumatic tourniquet is applied to the base of the arm.input:

The dorsal retinaculum of the extensor tendon is longitudinally cut on the ulnar side and raised en bloc to the radial side of the wrist.input:
output:The extensor tendons of the little finger, including the extensor carpis radialis longus and brevis and the extensor pollicis longus, are interconnected.input:
output:The radiocarpal capsule of the joint is opened, and Lister's tubercle is removed if necessary. The mediocarpal capsule remains unaltered. The sigmoid cavity is preserved, while the cartilage and subchondral bone of the radial epiphysis on the entire distal radius joint are removed.input:
output:An awl is employed to open the radius's surface in the intramedullary canal. The opening point must be slightly dorsal and radial to the center of the articulating surface of the radial joint.input:
output:A handle is used to insert the intramedullary nail through the opening point and advance it to the subchondral bone of the radius head.input:
output:A handle is used to insert the intramedullary nail through the opening point and advance it to the subchondral bone of the radius head.input:
output:The intramedullary nail is penetrated by a cannulated rasp, and the radius implant is inserted into the resulting space using a hammer.
