Final answer:
Treatment for a child with a floating elbow typically involves surgery to set and stabilize the fractures using pins, wires, or plates. Immobilization with a cast or splint is often necessary post-surgery, followed by physical therapy to aid in recovery.
Step-by-step explanation:
Treatment for a child with a floating elbow, which is a combination of a distal radius fracture and a supracondylar humerus fracture, will depend on the severity and stability of the fractures. In most cases, surgery is required to set the fractures and stabilize them with pins, wires, or plates. The humeral fracture is usually repaired first, followed by fixation of the radius fracture. After surgery, the child may require immobilization with a cast or splint for several weeks, followed by physical therapy to regain strength and mobility.
