Thumb Fracture

Thumb Fracture: Causes, Symptoms, and Treatment

A thumb fracture is a break in one of the bones that make up the thumb, most often the metacarpal (the bone connecting the thumb to the wrist) or the phalanges (the bones within the thumb itself). These injuries can result from falls, sports, or direct blows and may affect hand strength and function.

Symptoms of a thumb fracture include pain, swelling, bruising, and difficulty gripping or pinching. The thumb may appear crooked or shortened, and motion can be limited. In more serious cases, the joint may be unstable or bone fragments may shift out of place.

Diagnosis is confirmed with a physical exam and X-rays to determine the type and severity of the fracture. Treatment depends on whether the bones are aligned (nondisplaced) or out of place (displaced). Many stable fractures can be treated with a splint or cast. If the fracture is unstable, involves the joint, or significantly affects alignment, surgery may be needed to realign and stabilize the bone with pins, screws, or plates.

Most thumb fractures heal well with proper treatment and rehabilitation. Slocum’s orthopedic specialists provide expert care to restore thumb strength, mobility, and function.
