Broken Thumb: Symptoms, Diagnosis & Treatment

Your thumb has two bones called the phalanges. The most widely recognized break related to a broken thumb occurs in the long bone of your hand known as the main metacarpal. This bone interfaces with your thumb bones.

The primary metacarpal begins at the webbing between your thumb and pointer and stretches out back to the carpal bones of your wrist.

Where the main metacarpal joins your wrist is known as the carpometacarpal (CMC) joint. Most thumb bone fractures happen at the base of the principal metacarpal, just above the CMC joint.


Symptoms of a broken thumb include:

  • enlarging around the base of your thumb
  • serious torment
  • restricted or no capacity to move your thumb
  • outrageous delicacy
  • distorted appearance
  • cold or numb inclination

Most of these side effects can also happen with an extreme injury or tendon tear. You ought to see your PCP so they can determine the cause of your physical issue.

Diagnosis of Broken Thumb

You ought to see a specialist right away if you suspect you have a messed up or hyper-extended thumb. Two types of wounds may require immobilization with a brace and medical attention. A long wait for treatment can result in confusion or slow down your recovery process.

Your PCP will analyze your thumb and test the range of movement at every one of your joints. They’ll twist your thumb joints this way and that to check whether you’ve harmed your tendons.

An X-beam will help your PCP determine whether there is a crack and figure out where and what sort of break you have.

Breaks Versus Sprains

A sprained thumb happens when the tendons that interface the thumb joints stretch or tear. With an extended bone, there is no break in the bone, however, an individual might experience extreme pain and discomfort.

A few of the symptoms of a sprained thumb include:

  • swelling
  • a thumb joint that feels unsteady
  • An abnormality or knock present on the thumb joint
  • issues getting a handle on objects
  • enlarging
  • delicacy
  • Serious thumb injuries can separate the tendon from the thumb joint, causing it to feel shaky. Serious injuries often look like a break.
  • In some cases, an individual might have to consult a physician regarding deciding if they have a thumb sprain or a thumb break.
  • Extreme injuries might require careful adjustment — like the treatment of serious breaks.

Treatment for a Broken Thumb

On the off chance that you think you’ve broken your thumb, you can do a couple of things to help your side effects. These are while waiting to see a specialist. These include:

  • Take pain relievers – keep away from non-steroidal mitigating drugs (NSAIDs) until a specialist says taking them is OK
  • eliminating any rings from the harmed hand
  • not moving your thumb – have a go at tapping it to the finger close to it to keep it still
  • holding ice enclosed by a fabric against your thumb for 15 to 20 minutes each 2 to 3 hours to prevent it from expanding
  • holding your thumb up (if conceivable) to reduce the expanding

Clinical treatment might include:

  • desensitizing your thumb with a neighborhood sedative before fixing it back into its commonplace position
  • keeping your thumb still – for example by placing it in support or cast
  • giving you a lockjaw infusion or anti-infection agents (assuming there’s a cut) to forestall contamination
  • medical procedure, now and again – e.g. if you have nerve damage or many breaks in the bone.


Recuperation times for a broken thumb can vary depending on the type of treatment. For instance, assuming that an individual has a cast for their harmed thumb, they will likely need to wear it for 4 months and a half.

An individual might need to return to the specialist’s office for the specialist to remove the balancing out pins. This is normally somewhere in the range of 2 a month and a half after the physical issue happens.

When an individual has a cast after a medical procedure, a specialist will typically remove it about a month and a half later.

A specialist will for the most part suggest active recuperation following a thumb crack and after an individual has their cast removed. Non-intrusive treatment typically includes strengthening and extending activities to assist an individual with regaining development and strength in the thumb.

In any case, it may not feel like the thumb has recaptured its full capacity until around 90 days after the fact.

Inability to treat a broken thumb can result in joint inflammation or separation of the joint. This can cause ongoing pain, swelling, and enlarging.

Complications of broken thumb

Arthritis is a typical complication of a broken thumb. Some ligaments are generally damaged by the injury and aren’t replaceable. This increases the possibility of arthritis developing in the injured thumb joint.

An investigation of individuals who underwent nonsurgical treatment for Bennett breaks tracked down a high rate of joint degeneration and range-of-motion issues after 26 years. This prompted a higher use of medical procedures for Bennett cracks. Currently, there is no long-term observation of the perspective of those who have had a medical procedure for Bennett’s breaks.


Might I at any point move my thumb if it’s broken?

Side effects of a broken thumb include: swelling around the foundation of your thumb, extreme pain, and restricted or no ability to move your thumb.

Will a broken thumb mend itself?

A broken finger or thumb typically heals within 6 to about two months, though it may take longer. It very well might be 3 to 4 months before the original capacity is returned to you. Once it’s been repaired, you can use your finger or thumb as usual. Moving it will stop it from becoming solid.

What happens when a broken thumb is left untreated?

Inability to treat a broken thumb can result in arthritis or separation of the joint. This can cause persistent pain, swelling, and solidity.

How would you lash a broken thumb?

Ensure the tape isn’t too close and doesn’t restrict blood flow. With the second piece of tape, wrap one end around your internal wrist. Wrap the tape up over your thumb and circle it back down to the rear of your wrist. Repeat step 3 several times to get your thumb.


A broken thumb can cause severe pain and swelling, and it could be noticeably distorted. At times, a specialist might have the option to address the injury by repositioning the thumb back and applying a cast.

The requirement for a medical procedure will depend on the severity and location of the break. It is always wise to seek sure-fire treatment for advanced mending and decrease the risk of complications from a thumb crack that does not heal as expected.
