Final answer:
The last elbow apophyses to fuse during growth are the distal condyles of the femur. Fusion of these condyles occurs between the ages of 16-19 years.
Step-by-step explanation:
The distal condyles of the femur are the last elbow apophyses to fuse during growth. The ossification of the distal end of the femur, which forms the condyles and epicondyles, begins shortly before birth.
The fusion of the distal condyles occurs between the ages of 16-19 years, which is the final stage of growth for the femur.
