A dislocation is when the bones
in a joint slip out of their normal position. A dislocated thumb may happen from a
fall, blow, or sports injury,
especially if the thumb is bent back or jammed.
More to Know
An X-ray is usually used to diagnose a dislocated thumb. The bones may move back
into place on their own or a doctor may gently put the joint back with a quick maneuver
called a reduction. In some cases, surgery is needed to repair the joint.
To keep the joint from dislocating again, a splint is put on the thumb (the splint
might later be changed to a cast). The splint or cast is worn for a few weeks
while the thumb heals. Also, a sling (sleeve to hold the arm up) may be fitted to
help with swelling.
Keep in Mind
With proper treatment, most people who dislocate a thumb can gradually return to
their normal activities. The thumb may feel sore or stiff for a while.
