Thumb carpometacarpal (CMC) joint hemiarthroplasty (Cartiva Implant): aftercare advice

You have undergone surgery to replace the joint surface at the base of your thumb with a synthetic cartilage implant. Over the next few weeks you will be given advice by your therapist about your rehabilitation and the management of your hand. Getting a good result from this surgery is directly related to the effort you put into your rehabilitation, so please follow the advice and guidance below.

When can I return to my daily activities?

• Recovery from this operation can be slow. It can often be three to six months before you can start normal heavy activities again.

• Most patients are able to return to driving eight weeks after their operation. However this is a decision made by your surgeon or therapist.

• When you can return to work depends on the job you do, and should be discussed with your surgeon or therapist.

Two to six weeks after your surgery

• Two weeks after your operation your plaster will be replaced with a lighter thermoplastic splint. This splint must be worn all the time for a further four weeks, but may be removed each day for washing.

• You may have dissolvable stitches, which will gradually fall out and disappear around two weeks after your surgery.

• If you have non-dissolving sutures, these will be taken out either by your therapist at your follow-up appointment, or by the nurse at your GP surgery around two weeks after your surgery. If you have them removed by your GP practice nurse, you will need to book this appointment yourself.

• Compared to non-smokers, smokers are more likely to have complications in tissue healing and infections after surgery. For free friendly support and medication to help you stop smoking, contact One You Kent Smokefree Call: 0300 123 1220 or email or visit their web site.

• Elevating (raising) your hand is important to prevent swelling and stiffness in your fingers. Remember not to walk with your hand dangling down by your side, and do not sit with your hand held in your lap.

• Using a small amount of cream (such as E45 or Diprobase), massage your scar in deep circular motions. This helps prevent hypersensitivity, and the tendons becoming stuck to surrounding structures and causing problems with the movement of your hand.

It is normal for these exercises to be uncomfortable, but they should not cause pain. If they do:

• Try more gentler / smaller movements, with less repetition. Build up slowly.

• If your wound has healed fully and the dressings are off, you can do the exercises after warming your hand up in warm water or using a heat pack. This can help with pain and stiffness.

Exercises: six to 12 weeks after your surgery

Exercise 1

• Touch the tip of each finger one at a time with your thumb.

Further advice

• With the advice of your therapist or doctor, your splint is removed during the day. Keep the splint on at night until eight weeks after your surgery.

• After week four, you may use your hand for very light activities only (do not lift anything heavier than 0.5kg to 1kg in weight).

• Increase your level of activity as shown by your therapist, but do not do more than your pain allows.

• Avoid heavy pinch grips (for example holding a book open or tearing open packets) and lifting (see above) until 12 weeks after your surgery.

• Continue scar massage. Your scar may still feel tender; this is normal.

Will I have follow-up appointments?

Yes. How many appointments you have and how often you have them will depend on your recovery, and will be discussed with your therapist at your first follow-up appointment.
