New Motion Preserving Wrist Implant hits 1 year Milestone [Press Release]

September 13, 2016

FRANKLIN, Mass., Sept. 12, 2016 /PRNewswire/ — In May of 2015 the new motion preserving WristMotion™ hemiarthroplasty implant from Arthrosurface, Inc. (www.arthrosurface.com) was launched. The following month, the first patients were treated by the three co-developing surgeons, Dr. Randall Culp, Dr. Joseph Sherrill and Dr. Insok Yi. The WristMotion™ implant system is designed to intraoperatively map the curvature of the patients’ wrist joint and resurface the arthritic bone with a congruent and robust articular surface implant. To date more than 100 procedures have been performed across the US with new surgeons treating more patients every month. The product was launched at the ASSH Hand Meeting in September of 2015 to an overwhelmingly positive response.

There are a variety of conditions that lead to pain and arthritis in the hand joint, many of which are caused by previous trauma or chronic overuse. Historically, when patients developed arthritis in their wrist, several procedures were performed: a PRC (Proximal Row Carpectomy), a 4 corner fusion (4CF) or a joint replacement with implants. The implants either replaced one side (hemi) or both sides of the joint (Total). In the PRC procedure, the arthritic bones in the middle of the hand were removed and a new articulation formed between the remaining bones. In the 4 corner fusion procedure, the arthritic bones were left intact but immobilized so they no longer move against each other. The idea was that once the bones fused together, the pain would go away. Total replacements were performed more commonly than hemi’s and they involved significant bone resection. The WristMotion™ system consists of an anatomic implant to resurface the arthritic capitate bone. The implant creates a new articulating surface and is designed to preserve more bone than other implants, thereby providing patients with an alternative to other treatments.

Dr. Randy Culp said, “The bones in the hand are very uniquely shaped and contribute to the overall mobility of the hand. Whether we fuse or remove the bones for a PRC, we are making a compromise. Now that we can use an implant to reshape the bones to match each other, we have another way to preserve motion.” Follow-up on early patients has shown that the implants are stable, patients are able to return to their previous activities with pain-free motion and many have returned to sports such as golf.

Previously, surgeons promoted fusions or PRC’s over joint replacements. That thinking is starting to change. As Dr. Joseph Sherrill commented, “In spite of initial successful outcomes following PRC or four corner fusions, there is a significant failure rate over time due to progressive radio carpal arthritis. The WristMotion™ implant is an excellent treatment option for these patients who may be considering fusion but would prefer to maintain wrist motion.”

The WristMotion™ system is based on the same time tested principles of other Arthrosurface joint restoration systems. Match the implant to the patient and restore joint congruency using instrumentation that is reproducible and intuitive. “When I saw how well the knee and shoulder patients of my partners functioned when they used Arthrosurface, I thought that we needed something like that for the wrist. As hand surgeons we operate in a small space so instruments and implants need to be streamlined and small. The WristMotion™ system is extremely intuitive and reproducible which makes the procedure reliable and quick,” said Dr. In Sok Yi.

Steven Ek, CEO, Arthrosurface commented, “We are very excited about expanding our joint preserving technology into the hand and wrist. By adding new products to our extremity portfolio, surgeons have more options to treat disabling arthritis with unique and motion preserving solutions. For Arthrosurface, the extremity product line is a key to driver for our growth.”

    As of today, May 11, 2017, how many wrist surgeries have been performed using the arthrosurface implant? Realizing that “long term” results are not available what are the results to this point? After the surgery can pressure be applied to the joint such as in doing push ups or bench presses?

    Thanks and I very much appreciate your prompt reply. I need to doing something for my SLAC wrist in the very near future.

      Hello – We sent you an email with additional information.

      Thank you

      • Alex says:

        Interested as well – After the surgery can pressure be applied to the joint such as in doing push ups or bench presses?
        Any other sport activities, like bicycle riding, swimming or tennis?

        Thanks and I very much appreciate your prompt reply.
        I need to doing something for my SNAC wrist in the very near future, a month or two

    Available in Netherlands?

    • arthrosurface says:

      Yes, our products are available in the Netherlands.

    • Kevin Sheridan says:

      Can the procedure be applied to an already fused wrist to reverse what was done?

      • arthrosurface says:

        Hi Kevin- It is possible to reverse a Wrist Fusion, however there are many things for your surgeon to consider when deciding if it is a viable option for your specific situation.
        Some things for your surgeon to look at include, if the capitate’s bone stock is good enough to support the screw fixation of our WristMotion Implant and whether the lunate fossa’s cartilage is healthy or not. Please let us know if you have any other questions!

    Is this available in Canada?

  4. John baker says:

    I am a very active sports and fitness. I am wondering what the restrictions would be?

  5. Matrice Williams says:

    My 15 year old daughter has unfortunately been diagnosed with stage III Keinbock Disease. The doctor is recommending a proximal row carpectomy. Has there been any success using the arthrosurface implant for a patient with her diagnosis? Also, what is the youngest patient that has received the implant?

  6. Randy says:

    I am a golfer and was diagnosed with SLAC wrist years ago. I’ve managed to play competitive golf into my early 60s but now the discomfort in my wrist and thumb is affecting my golf swing. Are your implants suitable for a golfer who relies on his wrists to release the club. I am right handed and it is my right wrist that is affected.

  7. Gary Nick says:

    how quick is recovery time and can you go back to regular activities weight lifting and push ups chin ups Thanks Gary
