DRUJ Faq


1. What can I expect to gain from having this implant?

There are 3 main benefits:

1. The reduction or elimination of pain

2. Regained motion in the wrist/forearm 
3. Improved ability to lift and bear weight

2. How long will the operation last?

On average, the procedure will last between 1.5 and 2 hours.

3. Is this an Outpatient procedure or will I have to stay in the hospital?

With the exception of special circumstances, this is an outpatient procedure.

4. will I require a cast after surgery, and, if so, for how long?

In most circumstances, a bulky dressing will be worn post-operatively for approximately 2 weeks.

5. After surgery, when can I expect to have full use of my wrist?
At two weeks, you may begin unrestricted motion and limited lifting.  On average, a possible full return of use occurs by 6 weeks.

6. How can I get the prosthesis?

Visit your doctor and ask about the Aptis DRUJ prosthesis.

7. Is the prosthesis FDA cleared?

Yes, the Aptis prosthesis (aka The Scheker Prosthesis) has been cleared by the FDA for sale in the United States since 2005.

8. Is the Aptis prosthesis available in Europe?

Yes, the prosthesis is CE marked and has been available since 2005.

9. How many patients have the prosthesis?

Over 1,200 prostheses have been implanted, some patients with one in each wrist.

10. Is there any medical risk from the cobalt chromium?

There are risks with any implantable device, but studies have shown that cobalt chromium reacts more favorably with your body than the other available metals. Patients with nickel allergies, however, should be tested before the procedure to prevent any possible allergic reactions.

11. How about the Polymer ball? Any medical risk of an adverse reaction?

Again, there is always a possible risk associated with any implantable device, but the UHMWP ball has been tested through millions of weight bearing cycles showing almost unperceivable wear. This means it is very unlikely that material from the ball will cause a reaction within your body.

12. Is the prosthesis guaranteed? What if it breaks?

Due to not knowing how each individual will be using the device, it is impossible to guarantee implantable devices. However, the Aptis DRUJ is made up from a modular design and should a piece break, it can be replaced and should be covered by your insurance.

13. How many pounds can I lift after the prosthesis is in place?

The recommended maximum is 20lbs on the affected extremity.

14. Is this operation covered by my insurance?

This device and the corresponding procedure should be covered by your insurance, but be sure to check with your health care provider.

15. Are patients with Ehrlers-Danlos or Madelung's Deformity candidates for the Aptis DRUJ?

Yes, there have been several patients treated successfully. However, every patient is different and we always recommend evaluation by a certified health care professional.

16. Are patients with Rheumatoid Arthritis candidates for the Aptis DRUJ?

Yes, depending on the condition of the bone and if it will allow fixation of the device. The advantage of this prosthesis is that it can replace the displaced head of the ulna responsible for extensor tendon rupture frequently seen in Rheumatoid patients.

17. Can the Aptis DRUJ be used in patients when other DRUJ prostheses have failed?

Yes, this prosthesis has been used to replace all other prostheses currently on the market that have failed due to their inability to remain stable or wear into the bone.

18. Can this prosthesis be used in patients with wrist fusion?

Yes, it can reduce pain and allow motion of the DRUJ.

19. Can this prosthesis be used in patients when the radius and ulna have been fused together?

Yes, this is referred to as a one bone forearm, and we have seen success when the bones have been separated and the prosthesis implanted.

20. Can this device be used in patients who have had part of the ulna removed by other arthroplasties?

Yes, we have extended ulnar stems that can fill most voids. In extreme situations, custom length stems can be ordered.

21. Can patients with this device walk thru metal detectors?

Yes, we have not heard of anyone being stopped due to the detectors.
