Hyperextension Of The IP Joint

Hand

What is Hyperextension of the IP joint?

Hyperextension of the IP joint is a condition in which the middle joint (proximal interphalangeal joint) of a finger is forced backward and hyperextends. This can result in injury to the ligaments that support the joint, as well as the surrounding soft tissues.

The middle joint (proximal interphalangeal joint) of a finger is where your finger bends backward. The proximal end of your finger connects to your palm bone, while the distal end connects to your wrist.

If you hyperextend this joint, you may injure ligaments and/or surrounding soft tissues.

What are the types of Hyperextension of the IP joint?

There are three types of hyperextension injuries:

1. Partial dislocation (subluxation)

This occurs when there is partial separation between the bones and ligaments, but they remain connected by soft tissue. The fingers will have limited movement after this type of injury.

2. Complete dislocation

There will be complete separation between both bones as well as ligaments, so there will be no movement in the injured finger at all.

3. Subluxation with intra-articular fracture

In this case, only one side of the joint is dislocated while the other side remains intact; however, an intra-articular fracture may also be present so that it cannot move freely anymore because it has been damaged by an outside force.

What are the causes of Hyperextension of the IP joint?

A common cause is an injury to the ligaments of the middle joint of a finger. This may occur with a fall on an outstretched hand or from catching one’s finger in something. The ligament can be torn, which will cause swelling and pain, but sometimes only inflammation occurs without any specific injury to the ligament itself.

Another cause is tightness of the intrinsic muscles and increased pull at the central slip (the area where the tendon passes over). This could be secondary to rheumatoid arthritis, spasticity from traumatic brain injury, or stroke and intrinsic tightness alone.

If you have pain in your finger without any specific injury being present, it would be worth seeing a doctor as there may be another cause for your symptoms.

What are the symptoms of Hyperextension of the IP joint?

Symptoms of hyperextension of the interphalangeal (IP) joint include:

  • The pain is worse when you squeeze your fingers together and also when you open them out wide. It can be on one or both sides of your hand.
  • You may feel stiff if you try to bend your fingers too far back.
  • Tenderness over the knuckle area on the middle finger side of your hand.
  • The finger may look crooked (bent).

What are the risk factors for Hyperextension of the IP joint?

The risk factors for Hyperextension of the IP joint include:

  • Athletes and sportsmen are at a higher risk of suffering from hyperextension of the IP joint. This condition can affect anyone, but athletes are more likely to suffer from it than non-athletes.
  • The lack of flexibility in the IP joint leads to this condition. When there is a lack of flexibility in a joint, it can lead to hyperextension of that particular joint.
  • An accident, such as falling on an outstretched hand.

Recommended Exercise

Hand

What are the exercises for Hyperextension of the IP joint?

The exercises for Hyperextension of the IP joint are:

1. Finger curls

This is a great way to strengthen your fingers and help relieve the pain from hyperextension of the IP joint.

2. Finger press-ups

This exercise will strengthen your fingers, hand and forearm muscles, improving grip strength and relieving pain from hyperextension of the IP joint.

3. Wrist extension exercises

These work on strengthening your wrist muscles, which helps reduce pressure on the joints and ligaments that support them, reducing pain caused by hyperextension of the IP joint.

4. Ball Squeeze

The most common method to treat finger hyperextension is by using a tennis ball. Place the tennis ball on your desk and squeeze it with your fingers. You can also squeeze it between your knees or in the palm of your hand. As you squeeze, make sure to use proper form so that you don’t strain yourself.

5. Finger Stretches

Using your opposite hand, gently pull outward on the finger until you feel a stretch in your injured finger. It may take several weeks for this exercise to become effective so be patient and keep working at it!

What are the treatments for Hyperextension of the IP joint?

The treatment for this condition depends on its severity. In some cases, just resting the affected finger is enough to alleviate symptoms. In others, surgery may be necessary to correct the issue.

Resting the Finger

Resting your finger is an easy way to reduce pain and inflammation in your hand. If you have injured your hand or wrist, give it time to heal before resuming normal activities. Avoid any strenuous activity until you are pain-free and able to move normally again.

Buddy taping

Buddy taping is another way to treat hyperextension of the IP joint but it should only be used if there is no other option available. Buddy taping is basically bandaging a damaged finger together with a healthy one so that they can help each other heal properly. This method should only be used temporarily until your injury has healed enough so that you don’t need any more support from another healthy finger or toe anymore
