Which bone completes growth last?

Explanation:
Growth in bone length happens at the growth plates, and these plates fuse at different times for different bones. The clavicle is the last to finish growing because its secondary ossification center appears late and its growth plate remains open longer, typically into the early to mid-20s. The radius and ulna close their growth plates in the late teens, and the femur also finishes growing earlier than the clavicle. So, among these bones, the clavicle completes growth last.
