Hip prosthesis revision surgery

Indications for hip replacement surgery

Hip replacement surgery is indicated for several reasons, all aimed at resolving the complications or failures associated with an initial hip replacement.

Unsealing the prosthesis

Unsealing the prosthesis is a common cause requiring revision. Over time, prosthesis components can loosen from the bone, causing pain and instability. This condition can occur years after the initial implantation.

Component wear

The wear and tear of prosthetic components is unavoidable with time and use. Prosthesis materials can wear out, causing debris that irritates surrounding tissue and leads to inflammation. This wear often requires intervention to replace damaged components.

Infection

Infection around the prosthesis is a serious complication that can occur after initial surgery. It represents a risk of less than 0.5% in a patient without risk factors but this may increase with smoking, especially obesity. An infection may require new washing surgery or even require the removal of the prosthesis and reimplantation of a new prosthesis associated with prolonged antibiotic treatment.

Instability

This is when the prosthesis is unstable, that is to say that it presents a risk of recurrent dislocation. This happens when the femoral head of the prosthesis moves out of the acetabular cup. This may be caused by sudden movements, muscle weakness, or problems positioning the initial prosthesis. Revision surgery may be required to correct this condition. This risk has become very low with the use of minimally invasive approaches and certain congruent implants, in particular dual-mobility cups in case of risk factors.

Periprosthetic fractures

Periprosthetic fractures are fractures of the bone around the hip prosthesis. They can occur after trauma or because of bone fragility. These fractures often require surgery to repair the bone and stabilize the prosthesis.

Total revision of the prosthesis

A total revision of the hip prosthesis may be necessary when both components, acetabular and femoral, need to be replaced. This procedure is complex and requires careful planning to restore joint function and stability.

Benefits and risks of hip replacement surgery

Hip replacement surgery has many benefits, but like any surgery, it also has risks.

Benefits

The main benefits of hip replacement surgery include:

Pain relief: Reduction or elimination of chronic hip pain.

Improving mobility: Restoring the range of motion.

Quality of life: Significant improvement in the ability to perform daily activities and hobbies.

Durability of modern prostheses: The materials used allow the prostheses to last a long time.

Risks associated with my surgery:
‍
Hematoma, hemorrhage, phlebitis, embolism, cardio-respiratory disorders, death.
‍
Infection and in particular its risk factors such as smoking or obesity. Although rare, there is a risk of infection. Strict asepsis protocols are followed to minimize this risk.
‍
Neurologic disorders
‍
Transient or permanent functional disorders with persistent pain

Specifically on my hip surgery, there are infrequent risks of:
‍
Feeling of unequal length. Common after surgery, they are resolving and linked to the need to adapt the spine to your new anatomy.
‍
Luxation: The femoral head may move out of the cup, but modern, minimally invasive surgical techniques and appropriate rehabilitation help prevent this complication.

Component wear: Prosthetic materials can wear out over time, but modern dentures are designed to last for decades. This risk must be taken with care, as the data available in the literature often refer to older materials.

Metal allergy: Often a cause for concern for patients, it is a rare entity. A known allergy to certain metals should be reported to your surgeon prior to surgery.

Conclusion

Hip replacement surgery is an effective solution for treating the complications and failures of existing hip prostheses.
