The Arthrosurface HemiCAP® joint restoration technology was designed for patients who want to alleviate their joint pain but who also want to continue working and maintaining their active lifestyles. Many patients are looking for a treatment option that “bridges the gap” between a cheilectomy and a fusion plate or total toe replacement.
The Toe HemiCAP® implant system is designed to match the shape and contour of the individual patient’s cartilage surface. It is a contoured cap that replaces the area of damaged cartilage and is designed to protect the remaining (healthy) cartilage in the joint. Instead of a one-piece implant with a stem built in, the HemiCAP® is two components. It consists of a cap and screw that mate together via morse taper lock. Stemmed implants have been shown to loosen, whereas the HemiCAP® screw system has been a stable construct with no reported loosening over the last 10 years. The idea behind the system is to prevent further damage to the joint while maintaining the patient’s native anatomy and motion.
For patients with extensive damage on both sides of the joint, Arthrosurface® also provides a total toe restoration called the ToeMotion™ system. This consists of the Toe DF HemiCAP® implant on the metatarsal side of the joint and a metal baseplate with plastic insert for the opposing (phalangeal) side of the toe joint. The Arthrosurface® total toe is different than other existing replacements because it is implanted into the bone rather than on top, leaving natural bone to support the implant around its edges. This type of implant placement does not disturb any surrounding tissue attachments which are needed to maintain stability and lift-off for walking. The Arthrosurface ToeMotion™ is also the only total toe replacement that is implanted with screws on both sides of the joint to provide rock-solid fixation.
The Arthrosurface® toe systems are indicated for the treatment of patients with the following clinical conditions: hallux rigidus, hallux limitus, hallux valgus and an unstable or painful MTP joint. The implants are designed to match not only the diameter of the damaged area but also the precise radius of both curvatures on the patient’s joint surface. Once the mapping points are defined, the appropriate implant is chosen and then implanted into the patient. Different diameters & curvatures are available to provide a proper fit for each individual patient.
For patients looking to maintain an active lifestyle, receiving a fusion and never being able to move their toe again is not a viable or appealing option. With the Arthrosurface HemiCAP® systems and the ToeMotion™ total toe restoration, patients now have an option that is minimally invasive, completely stable and motion preserving.
With the Arthrosurface® Systems, the surgeon only restores the damaged area of the joint, similar to the way a dentist fills in a cavity, leaving the rest of the structures in your joint intact. This way, your native anatomy is preserved. The exposed and painful bone is covered, while all the structures in your joint that help you move and function properly are left in place allowing you to return to your normal active lifestyle.
- It is custom matched and fit to a patient’s joint size and shape
- Significantly less cartilage and bone is removed than traditional joint replacements
- It is placed into the surface rather than on top, leaving the joint less surgically altered
- Joint motion and the native structures are preserved so no bridges are burned
The HemiCAP® implant was the first implant designed for the metatarsal side of the joint, which is where the arthritic changes begin. This side also tends to have more wear and tear as well as spurring. Other hemiarthroplasty devices replace the phalangeal side, which may still have remaining cartilage and fails to address the primary disease site, which is the metatarsal.
For many patients who have widespread arthritis with damage on both sides of the joint, the Arthrosurface ToeMotion™ system can be a great option. This system restores both sides of the joint by implanting a HemiCAP® on the metatarsal side and a metal baseplate with plastic insert on the opposing side of the joint. Unlike standard total toe replacements or fusions, the ToeMotion™ system can restore a natural range of motion while alleviating or eliminating pain.
- Aged 35 to 75 years old
- Want to regain your active lifestyle
- Want to be able to bend your toe, reach up and kneel again
- Want to wear normal shoes such as high heels or boots
- You want to fix your toe problem now versus waiting for your toe to undergo further damage
- You may have been told by a surgeon that you will need a toe fusion in the future
Here are a few helpful suggestions as you recover and rehabilitate from your toe surgery:
- Follow the recommendations of your surgeon and physical therapist.
- Keep a log to track your progress as you recover and increase activity.
- Ask for assistance from family and friends to help with chores and errands during your recovery.
- Walking aids such as crutches or a cane may reduce stress on your operated toe
- Eliminate possible tripping hazards in your home – wires, cables, rugs, etc.
- Return to any moderate or demanding activities should be guided by your tolerance for weight bearing.
We wish you good luck with your decision and your treatment
Toe HemiCAP® systems are approved for use in the USA, CE Marked countries and many other markets around the world.
