Revision Hip Replacement
Dr. Ajoy Jana - Omaha, Ne
Dr. Jana has extensive experience taking care of replacements that have worn out or failed. The most common reasons for revision of a previous hip replacement are:
Plastic (Polyethylene) Wear
The plastic part of the prosthetic hip socket can simply wear down over time. In many cases, replacing only this plastic piece will provide many years of continued good function without having to replace the parts of the prosthesis that are attached to the bone.
Hardware Loosening
Over time, the prosthetic parts that are attached to the femur and/or pelvis can become loose. A loose prosthesis causes pain and needs to be replaced
Infection
Although infections are uncommon, they are a very serious complication. Patients are often surprised to learn that infections can happen right after surgery or months or years later. Most hip infections that happen long after the surgery occur when an infection from another part of the body spreads to the replaced hip through the blood stream.
Bone Damage
As the prosthesis is put through year after year of use, microscopic debris is produced that can cause the bone to deteriorate, get soft and form large cysts. This can cause pain, loosening of the prosthesis, and even fracture.
Dislocation
If a patient's artificial hip keeps coming out of the socket, surgery to change some or all of the prosthetic parts can usually stabilize the hip. This is the most common cause for revision when hip replacement is done through the posterior approach.
