CPT® Code 24410

The procedure described by CPT® Code 24410 involves multiple osteotomies of the humeral shaft, specifically utilizing a technique known as the Sofield type procedure. An osteotomy refers to a surgical operation in which a bone is cut to facilitate realignment. In this case, the humeral shaft, which is the long bone of the upper arm, is targeted to correct deformities that may arise from conditions such as malunion, where a bone heals improperly, or osteogenesis imperfecta, a genetic disorder characterized by fragile bones. The specific type of osteotomy performed can vary based on the nature and location of the deformity, with options including transverse, wedge, sliding, and angular cuts. During the procedure, an incision is made in the upper arm to access the affected area. The surgeon carefully dissects the soft tissues to expose the humerus and elevates the periosteum, which is the membrane covering the bone. Using surgical instruments such as drills, saws, or osteotomes, the bone is cut according to the predetermined configuration necessary for correction. After the osteotomies are completed, internal fixation devices, such as pins, screws, or plates, may be applied to stabilize the bone fragments in their new alignment. In this specific procedure, an intramedullary rod is inserted to provide additional support and alignment. The intramedullary rod is positioned within the canal of the humerus, and the bone is secured at each osteotomy site to ensure proper healing and restoration of function.
