Dislocation Following Total Hip Replacement

Hips

What is Dislocation Following Total Hip Replacement?

Dislocation Following Total Hip Replacement is a condition that occurs when the ball and socket joint of the hip become dislocated, or separated, from each other. This can be caused by trauma, such as an accident or fall, or it can occur spontaneously.

A dislocation following total hip replacement is different from a broken hip because it involves damage to the prosthetic components of the hip joint rather than to the bone itself. The exact cause of this type of dislocation is not well understood.

Dislocation Following Total Hip Replacement is usually treated with surgery to reposition the ball and socket joint back into their correct position in the pelvis. If you have already had surgery on your hip joint and experience pain or swelling around it, contact your doctor immediately so they can determine whether you need more treatment or if there may be another underlying cause for your symptoms.

What are the causes of Dislocation Following Total Hip Replacement?

The causes of Dislocation Following Total Hip Replacement may be due to any of the following:

1. Post-operative factors

  1. The dislocation is a result of infection or any other post-operative complication.
  2. The dislocation may occur due to overstretching of the ligaments, which are responsible for keeping the ball and socket joints intact.

2. Pre-operative factors

  1. The dislocation may occur if the hip replacement has been done in an inappropriate position or there are excess amounts of bone fragments in an area where bone grafting was done.

What are the symptoms of Dislocation Following Total Hip Replacement?

The symptoms of dislocation following total hip replacement include:

  • Pain in the groin area
  • Feeling like your leg is “losing” strength and becoming numb or weak
  • Feeling like you have no control over your leg (you may be unable to lift it)
  • An inability to stand up straight or put weight on your leg
  • A sensation of something being out of place in your hip area
  • Pain when you move your hip or knee while lying down
  • Severe pain around the joint
  • Reduced mobility
  • Difficulty walking or performing physical activities

What are the risk factors for Dislocation Following Total Hip Replacement?

The risk factors for dislocation following total hip replacement are the same as the risk factors for dislocation following any joint replacement, which include:

  • poor bone stock at the time of surgery
  • poor bone quality
  • poor soft tissues (ligaments, cartilage)
  • a patient who is elderly or in poor physical condition
  • a patient who has a history of smoking or other forms of exposure to carcinogens

What are the complications of Dislocation Following Total Hip Replacement?

The main reason for dislocation following total hip replacement is an improperly positioned or malpositioned hip replacement. This means that the surgeon did not place the new hip ball in the correct position, and as a result, the patient may experience significant pain and discomfort. This can lead to further complications if left untreated, such as joint stiffness and osteoarthritis.

Other complication includes:

  • Infection (bacterial or fungal)
  • Blood clots (deep vein thrombosis)
  • Osteonecrosis (bone death)
  • There are many reasons why a surgeon might not properly position or malposition a hip replacement:
  • Poor bone quality
  • Inadequate surgical technique
  • Improper preoperative planning

What are the exercises for Dislocation Following Total Hip Replacement?

If you have dislocated your hip, there are several exercises you can do to help prevent it from happening again. Here are a few of them:

Ankle pumps

When you are sitting in a chair, lift your toes off the floor and then lower them again. Repeat 10 times.

Thigh squeezes (quadriceps sets)

Tighten the muscles in your upper leg by pressing your thigh against a table or wall with your knee bent and your foot flat on the floor in front of you. Hold for 5 seconds, and then relax for 5 seconds before repeating 10 times.

Buttock squeezes (gluteal sets)

Tighten the muscles in your buttocks by pressing against a table or wall with each leg crossed over the other at the ankle and both knees bent at 90 degrees or less (so that they don’t touch the table or wall). Hold for 5 seconds, then relax for 5 seconds before repeating 10 times with each leg crossed over the other at the ankle and both knees bent at 90 degrees or less (so that they don’t touch the table or wall).

What are the treatments for Dislocation Following Total Hip Replacement?

The most effective treatment for dislocations following total hip replacement is the use of a multimodal protocol including patient education, the use of large femoral heads, posterior soft-tissue repair, and intraoperative adjustment of limb length and hip offset. This approach has been shown to reduce the dislocation rate by more than 50%.

Patient education should include the importance of avoiding certain activities (such as running) and using anti-inflammatory medication if hip pain occurs.

Large femoral heads are used to increase stability in the joint.

Posterior soft-tissue repair is performed during surgery to ensure that there is enough soft tissue at the back of the hip socket to hold it in place.

Intraoperative adjustment of limb length and hip offset ensures that these factors are balanced during surgery so that dislocation does not occur later on.

What brace is used for Dislocation Following Total Hip Replacement?

The abduction brace is used to prevent the hip from dislocating after total hip replacement surgery. It works by keeping the leg from moving too far out to either side. The abduction brace comes in a variety of sizes, so make sure you measure your leg carefully before ordering a custom fit version.
