Wrist fractures are breaks in the small bones in the wrist or the ends of the forearm bones. Treatment may include a splint, cast or surgery, depending on the severity and location of the break. Rehabilitation therapy is usually part of the recovery process.
Some wrist fractures can interrupt blood flow to a wrist bone, causing part of it to die. If this occurs, a piece of bone taken from another location in the body (bone graft) may be inserted to help the fractured bone heal. If the bone doesn't heal, several wrist bones might need to be fused together.
