Our Summary

This study looked at how fusing the joint closest to the palm on the index finger (a procedure called arthrodesis) at different angles impacts the overall function and movement of the hand. It’s important to note that while this procedure can help create a stable, pain-free joint, it also means that the joint can’t move anymore.

The researchers had 20 healthy people perform basic hand activities with their index finger joint either free to move or fixed at certain angles (0, 20, and 40 degrees). They then recorded their motions and asked the participants about their experiences.

They found that fixing the joint at 0 degrees made the tasks seem harder, took longer, and affected the range of motion in more joints of the hand compared to when the joint was free or fixed at 20 or 40 degrees. Therefore, the researchers suggest that if this procedure is necessary, the joint should be fixed between 20 and 40 degrees for the best results. However, they also suggest that more activities need to be tested to confirm this.

Doctor’s Tip

A doctor might tell a patient undergoing joint fusion to follow a rehabilitation program to strengthen the surrounding muscles and improve overall function of the hand. They may also recommend regular physical therapy to maintain flexibility and prevent stiffness in the joint. It’s important for patients to follow their doctor’s instructions and attend follow-up appointments to monitor progress and address any concerns.

Suitable For

Patients who are typically recommended joint fusion are those who have severe arthritis or joint damage that causes chronic pain, instability, and limited function in the affected joint. Joint fusion may be recommended when other treatments, such as medication, physical therapy, or injections, have not provided sufficient relief. Additionally, patients with certain deformities, fractures, or joint instability may also benefit from joint fusion to stabilize the joint and improve overall function. It is important for patients to discuss the potential risks and benefits of joint fusion with their healthcare provider to determine if it is the right treatment option for their specific condition.

Timeline

Before joint fusion:

  1. Patient experiences persistent pain, swelling, and limited range of motion in the affected joint.
  2. Patient may undergo various conservative treatments such as medications, physical therapy, and injections to manage symptoms.
  3. If conservative treatments are ineffective, patient may be recommended for joint fusion surgery to stabilize the joint and alleviate pain.

After joint fusion:

  1. Patient undergoes joint fusion surgery, where the bones are fused together to create a stable, pain-free joint.
  2. Patient goes through a period of recovery, including physical therapy to regain strength and range of motion in the hand.
  3. Patient may experience improved stability and reduced pain in the affected joint.
  4. Patient may need to adjust to limitations in movement in the fused joint, as it can no longer move freely.
  5. Patient may need to make modifications in daily activities to accommodate the limitations of the fused joint.
  6. Overall, patient may experience improved function and quality of life after joint fusion surgery.

What to Ask Your Doctor

Some questions a patient should ask their doctor about joint fusion include:

  1. What are the reasons for recommending joint fusion in my specific case?
  2. What are the potential risks and complications associated with joint fusion surgery?
  3. How long is the recovery period after joint fusion surgery?
  4. Will I need physical therapy or rehabilitation after the surgery?
  5. What limitations in movement or function can I expect after the joint fusion?
  6. Are there alternative treatments to joint fusion that I should consider?
  7. How long will the effects of joint fusion last?
  8. What is the success rate of joint fusion surgery for my condition?
  9. Will I need any additional surgeries or treatments in the future after joint fusion?
  10. Are there any specific activities or movements I should avoid after joint fusion surgery?
