CMCJ OA
John Hardy, Consultant Orthopaedic Surgeon working at a Private London Clinic said "I use them for grade one Gamekeepers Thumb in skiers and after injection of patients with osteoarthritis of the carpometacarpal joint (CMCJ) of the thumb.
If your patient has osteoarthritis at the base of the thumb you have a high chance of controlling symptoms with simple conservative treatments like Non-steroidal Anti-inflammatories, a temporary splint for rest and occasionally a cortisone injection. The need for surgery for this condition is rare and no one should be offered it without an attempt at simple treatment first.
I do the injection using a local anaesthetic so there is no pain. I mark the level of the joint with my fingernail.
I then ask a nurse assistant to hold the patient by the thumb to distract the CMCJ. I first use a 2 ml syringe and a blue needle with 2ml of 1% plain lignocaine local anaesthetic and then about 10mg of kenalog cortisone". I always warn the patients about the very small risks of a flare up over the first 24 hours, infection, depigmentation, lipoatrophy, syncope and no cure. The DonJoy® Rizoform Thumb Brace is very comforting worn after the injection.
