How do I Treat a Dislocated Thumb?


A splint is often an ideal way to keep a dislocated thumb immobilized.

The dorsal collateral ulnar collateral ligaments are the two main ligaments that keep a person's thumb in the proper place. When either of these ligaments is torn or damaged, usually after some sort of trauma, it is known as a dislocated thumb, or sometimes a jammed thumb. This is often extremely painful, and can result in abnormal thumb alignment if not treated properly. Resting and icing the dislocated thumb until you can receive proper medical care is considered to be very important. Afterward, your doctor will decide which type of treatment you need, depending on the severity of the injury.

If you even suspect that you may be suffering from a dislocated thumb, experts agree that the first thing you should do is rest the area, and stop using it. Though it might seem like the right thing to do, you should never try to fix or realign a dislocated thumb on your own. This can cause permanent damage to the tissues in the area.


Many doctors also recommend ice be applied to a dislocated thumb. To do this, apply an ice pack to the palm of the hand just under the thumb. If no ice pack is readily available, anything cold or frozen will do, such as a bag of frozen vegetables. This will lessen the amount of pain, as well as reduce the swelling in the affected area.


Someone who has a dislocated thumb should avoid typing as much as possible.

Splinting the dislocated thumb is one of the best ways to immobilize it. Your hand can swell substantially with this condition, so it is important to remove any jewelry from your hands. These can cut off the circulation, and cause some serious problems. Rings that are not easily removed may need to be snipped off with a ring cutter.

When splinting the thumb, try to keep it in the same position that it ended up in, if at all possible. If you do not have an actual thumb or finger splint available, a straight, flat, hard stick, such as a popsicle stick, will do in a pinch. Begin by placing the stick gently on the palm, following the thumb. You can then tape the splint to the thumb, taping the tip of the thumb to the splint first. You can then tape the bottom of the splint as close to the thumb joint as possible, and finish by wrapping the thumb, splint, and hand with either an elastic bandage or a roll of gauze.

Even if you think that the dislocation is not severe and will heal on its own, immediate medical attention is strongly recommended to prevent further, more permanent damage. Probably the first thing that a doctor will do when you seek treatment for a dislocated thumb is take an x-ray. This will allow him to see the extent of the damage, including whether you have any broken bone. The dislocation can either be a simple or a complex dislocation.

A medical doctor can determine whether a thumb is dislocated, sprained or broken.

In the case of a simple thumb dislocation, the ligaments are usually either stretched or torn only slightly. This kind of dislocated thumb is considered to be the easiest to treat, and usually just requires the doctor to maneuver the thumb back into the joint. Many times, the thumb will need to be immobilized, usually with a cast, for approximately three weeks. Afterward, the ability to move the digit slowly comes back.

A complex thumb dislocation is typically a little more serious, because at least one of the ligaments is torn completely. Most of the time, surgery is required to repair the damage. After the surgery, the thumb will usually need to be immobilized for up to six weeks. Some patients may also require physical therapy to regain full range of motion.
