Metal ion blood levels determine

Patients with “metal on metals” (artificial hips) are at risk of complications due to adverse reactions to metal debris (Armad). A study published on September 20, 2017 in the Journal of Orthopedic Surgery confirmed that levels of blood-specific metal ions for the type of hip implant used may help predict patients at low risk of erythema.

The use of special parts indicates an implant to reduce the number of Navy cases compared to the use of the currently recommended US thresholds. and missing British regulatory authorities, according to a report Golraj S. Matharo BSc (Hons), Marcus, magnetic resonances, Leadville of Oxford University and colleagues. The results provide an advanced method to predict the risk of patients in the Navy with two types used in a wide range of minerals in hip hip replacements: Rissourvasing hip sow Birmingham (mainland) and Kuraijl-Pinnacle plantation.

Metal ion blood levels determine patients under aramad risk

Patients may develop negative feedback on the metal debris generated by the positioning surfaces by sliding over themselves into the artificial joint. It is recommended to measure levels of chromium and cobalt ions in the blood, reflecting the presence of small molecules of worn implant surfaces as part of the patient’s early follow-up. However, there is no agreement on the specific levels of metal ions that should raise concerns after replacement of the mother’s hip. Previous studies by Dr. Matthrow and his colleagues suggest that the use of specific implant thresholds may improve the ability to detect patients at low risk of developing aramad.

To confirm this approach, the researchers carried out an external validation study involving 710 patients (803 hep) undergoing hip replacement in March using one of the two hip prostheses in three European hospitals. It has been tested specific implant points versus the regulation of fixed energy points for metal ion blood rates for its ability to bind with the clinically diagnosed Armed, and rates 12 percent after replacing the single hip, and 18 percent after replacing a hip double hip, and 7 percent after a Hip Corel-Pinnacle Replacement.

Specific cutoff points implant well in distinguishing between patients with and without. Allergies – The percentage of patients with erythema that have levels above the specific ion-transplant threshold – ranged from 65 to 79 percent in all three groups. Equally important, the negative predictive value – the percentage of patients who did not have ARMs that had ion levels below the threshold – was 93 to 97 percent between the groups.

In general, specific cutoff points were identified for all transplants, but 2.8 percent of the cases were expanded. On the contrary, fixed regulatory controls did not reach 6.5% of the cases.

Early identification of anaphylaxis is important, especially for some patients in whom early detection (removal of implantation and replacement) can reduce complications and give the patient better results. The new findings confirm the value of plant blood parameters to help assess the risk of vascular injury after hip replacement.

The use of these cut-off points helps identify patients who should be closely monitored for asymptomatic as possible, while minimizing the use of additional testing in patients is unlikely to be or developing a wider one. But Dr. Matthrow and his colleagues say there is not a single test that can determine if the patient really has a cure or what treatment is needed.
