In addition, broken thumbs in children can permanently affect their growth by damaging their growth plates. Even if you suspect the injury might be a sprain (torn ligament) rather than a bone fracture, you should still see a doctor for an accurate diagnosis. Additionally, some serious sprains can still require a hand surgeon to repair. You should ultimately leave the final diagnosis and treatment decisions to a medical professional.

This will not only confirm that diagnosis, but it will also show the doctor exactly how many fractures your thumb has sustained, which will assist in determining the best treatment option. The angles for the x-rays include:  Lateral: The lateral view is an x-ray with the hand resting on its side, so that the thumb is up. Oblique: The oblique view is an x-ray with the hand tilted, resting on its side, so that the thumb is up. AP: The AP view is an x-ray of your hand in a flattened position, from above. A CT scan can also be referred to as a computerized axial tomography (CAT) scan.

This way, your doctor can get a better idea of what the break is like and the best way to go about fixing it. Tell your doctor if you are pregnant because CT scans might...
