Your thumb has two bones called the phalanges. The most common fracture associated with a broken thumb is actually to the larger bone of your hand known as the first metacarpal. This bone connects to your thumb bones.
A hand fracture is a break in one of the bones in the hand. This includes the small bones of the fingers phalanges and the long bones within the palm metacarpals. A broken hand can be caused by a fall, crush injury, twisting injury, or through direct contact in sports.

Thumb X-rays pass through skin and soft tissue mostly, but do not pass through bone or metal easily. As different tissues in the body absorb different amounts of radiation, the images will show different shades of black and white. One of the most common uses of a thumb X-ray is to check for broken bones after an accident, but they are also used under many other circumstances. Thumb X-rays are used to identify, diagnose, and treat many types of medical conditions.
The thumb has two bones - the distal phalange placed between the tip and the knuckle; and the proximal phalange extending between the knuckle and the base. The first metacarpal connects the thumb to the hand. A break or a crack in any of these bones is called the thumb fracture.
Thumb fractures can range from fairly straightforward, clean breaks all the way to multiple fractures along a joint that require surgery to repair. Since injuries to a thumb can have lifelong effects on everything from eating to your occupation, the injuries should always be taken seriously. To diagnose a broken thumb, note any severe pain immediately following the injury. Additionally, check if your thumb is bent at an odd angle or is twisted in a strange way, which may indicate a broken bone.
