Patients who experience a corrosion of components in Stryker hip implants may need to receive a revision surgery. As Stryker components become worn, they can release metal debris into the bloodstream. The release of metal debris can then trigger conditions like metallosis (see here) and adverse tissue reaction. If patients experience pain and swelling, these can be indicators of adverse tissue reaction. Patients who have these symptoms should speak with a physician about their options and whether they may require a revision surgery.
Diagnosing Issues Related to Stryker Hip Implants
Those who have Stryker hip implants may wish to speak with a medical professional about any issues related to the implant. Ever since Stryker Orthopaedics initiated a voluntary recall of the Rejuvenate and ABG II systems in 2012, thousands of patients have experienced pain, swelling, infection and other serious health issues as a result of defects in the Stryker hip implants.
People who experience a loss of mobility or cannot place weight on a hip may require a revision surgery (learn more about these procedures here). A patient may feel pain in an area in which a hip implant component has loosened. Prior to any hip revision surgery, a physician will conduct a diagnosis to detect the exact causes of pain in the patient. He or she will study the movement of the components in the hip region and detect whether corrosion has impacted the hip implant. The physician can also determine whether a patient has developed an infection, and this may require immediate revision surgery. Symptoms of an infection include swelling, redness, itching and extreme pain. A revision surgery may be required for patients who have deep infections.
Symptoms Leading to a Stryker Hip Revision Surgery
A patient may experience other symptoms or conditions that indicate a revision surgery may be necessary. These symptoms and conditions include:
- Dislodged neck component
- Broken stem
- Dislocated bone
- Severe swelling or infection
- Metal poisoning
Preparation for Hip Revision Surgery
Prior to the hip revision surgery, a physician will need to prepare a patient. Preoperative preparation may include determining any health conditions that can be contraindications for hip revision surgery. These conditions may include a mental disorder, depression, cancer or other terminal illness, infection, obesity, and paralysis. The physician will also prepare X-rays and diagnostic images to review before the operation. If a patient has a dislodged bone or other unusual condition, then special procedures may be required for his or her treatment. A patient who has severe bone loss may not be an eligible candidate for hip revision surgery.
Procedure Involved in Hip Revision Surgery
During the operation, a physician will remove the old hip implant. The physician cleans and sanitizes the hip socket. He or she then places a new shell in the acetabulum. The actual revision of the hip implant is the most difficult and arduous part of the surgery. This part entails cutting apart the hip bone and then cementing a new implant into the femur. If a patient has weak bones, a physician may need to implant bone grafts to strengthen the new structure.
Physicians may also use a ballistic chisel technique to remove old cement pieces. The chisel can be used to crack old cement and loosen a defective hip implant. The physician then implants the new femoral component and stitches up the incision.
Risks Associated with Hip Revision Surgery
Every patient should be informed of the serious risks associated with hip revision surgery. Research studies have indicated that risk factors may affect certain demographics. For example, African American patients frequently have more complications than Asian Americans or Caucasians. Men also struggle with recovering from a hip revision more often than women. Some of the other risks associated with hip revision surgery include:
- Risk of death
- Development of infection
- Need for additional revision surgeries
- Adverse tissue reaction
Aftercare: Recovering From a Hip Revision Procedure
After hip revision surgery, physicians may suggest that patients use a walker, cane or wheelchair to move around for a few weeks. Patients may also need to permanently use a walker depending on the pain that they experience after a revision surgery. Doctors may prescribe pain-killers for patients after a revision surgery and may also provide instructions for cleaning the wound area.
