CPT® Code 24516

Treatment of humeral shaft fracture, with insertion of intramedullary implant, with or without cerclage and/or locking screws

The CPT® Code 24516 refers to the treatment of a humeral shaft fracture through the insertion of an intramedullary implant, which may be accompanied by cerclage and/or locking screws. This procedure is categorized as an open treatment method, meaning that it involves surgical intervention to stabilize the fracture. The use of an intramedullary implant allows for internal fixation of the fracture without the need for direct exposure of the fracture site. The procedure can be performed using either an antegrade or retrograde approach, depending on the specific circumstances of the fracture and the surgeon's preference. In the antegrade approach, an incision is made over the proximal humerus, which may involve the rotator cuff or be positioned laterally to the articular surface. The intramedullary nail is then inserted into the medullary canal of the humerus and is typically secured with locking screws that are placed both proximally and distally to enhance stability. Conversely, the retrograde approach involves splitting the distal triceps muscle and drilling a hole in the olecranon process to facilitate the insertion of the nail. A locking screw is then placed at the proximal end of the nail to secure it in position. Throughout the procedure, the stability of the fracture is assessed, and if necessary, wire cerclage may be employed to provide additional support to the fracture fragments. Radiographic verification is often utilized to ensure adequate reduction and alignment of the fracture fragments post-insertion.
