All metal hip devices are under surveillance because of the problems related to these prostheses that were reported, news reports say. There were even several DePuy ASR XL Acetabular Systems that were removed because of the high failure rate and complication reported by patients, according to the Food and Drug Administration (FDA), the prosthesis was voluntarily recalled by DePuy Orthopedics after the complications started to surface. Men and women who have the recalled hip device are now questioning the safety of the prosthesis. The complications from these hip devices are continually being monitored by orthopedic specialists.
The FDA has included the complications related to the use of these devices in the product safety information that they have released. If the recalled device has already been implanted, then the best option for patients is to monitor the symptoms. Early detection may give way to early treatment to prevent the damage from spreading. The concentration of metal ions due to the wear and tear of the prosthesis is thought to be the cause of the problem. Reducing the adverse events related to these implants may be done by surgeons through looking at the patients that would best benefit from this of type prosthesis.
The cobalt and chromium ions may or may not harm patients. Depending on the sensitivity of the patient to the cobalt and chromium ions, adverse reactions may vary. Adverse local tissue reaction may lead to soft tissue damage. Eventually, the device might loosen and fail because of these localized lesions. Factors that may increase the risk of adverse events are the following:
- Age – younger patients are prone to develop this problem.
- Gender – women have an increased risk of developing this complication.
- Weight – the added weight adds more pressure to the joint and this makes overweight individuals at risk.
- Diagnosis – more damage may ensue depending on the diagnosis of the patient.
- Activity level – the joints may experience more pressure because of high activity levels.
If there is evidence of device failure, patients may follow-up with their orthopedic specialist. MedWatch or the FDA Safety Information and Adverse Event Reporting Program helps in monitoring the reports of health care providers, patients and medical device manufacturers. These adverse events may need to be reported, in order to build a database. The risk of faulty metal hip implants may put the health of patients in serious condition.
