An Overview on Revision Hip Replacement Surgery

????????????????????????????????????????????????A number of patients choose metal-on-metal (MoM) hip implant because it is marketed to be more durable and lasts longer than other types of hip prosthesis. However, MoM hips have been found out to break down at a faster rate which may potentially damage the tissues and the bones surrounding the implant, resulting to inflammation, swelling, dislocation and loosening of the implant. MoM patients have allegedly pointed that hip replacement manufacturers failed to disclose its potential dangers, according to media reports.

Stryker Rejuvenate Modular hip recall is a procedure in which the damaged hip prostheses are replaced with a new one. Hip revision surgery has three major goals: relieving pain in the affected hip; restoring the mobility; and removing the damaged or loose prostheses before irreversible harm is done to the joint. The approaches are the same when performing the initial hip replacement procedure but the surgical approach associated with revision may be extended with an increased exposure for what is a more complex procedure. It is usually done by an orthopaedic surgeon.

Revision surgery is always a tough challenge to both patient and surgeons. This is so even when infection is not present. The most difficult issue to manage is the threat of bone loss around the implants. When a primary hip replacement starts to loosen, the bone surrounding it may gradually thin, leaving less bone to insert a new implant into and in the worst cases thinning so much that fracture occurs. Inserting a new component into the thin bone is a possibility, but the revision operation may not last long if this technique is used.

One popular brand of MoM hip implants is Stryker. It keeps two known products, Rejuvenate and ABG II, which have been very controversial. These products were marketed to provide increased stability, better movement, and superior fit over other hip replacement products available in the market. However, Stryker Rejuvenate Modular hip recall is very dangerous and causes health complications. Because of these concerns, these implants should be closely monitored to watch for potential problem.
