Bicompartmental Knee Resurfacing System
| ConforMIS, Inc. announced the launch of a patient-specific bicompartmental knee resurfacing implant. The iDuo is a bicompartmental resurfacing implant designed for patients whose arthritic damage is limited to either the medial or lateral compartment of the knee, in addition to the patellofemoral compartment. ConforMIS emphasizes that the iDuo resurfaces only the affected areas, preserving far more bone on both the femur and tibia than traditional knee replacement surgery. The iDuo also preserves both the anterior and posterior cruciate ligaments, helping to maintain natural knee kinematics. The extent of tissue preservation with the iDuo helps patients retain their future surgical options. The implant is 510(k) cleared for marketing by the US Food and Drug Administration. The iDuo was developed for patients with advanced osteoarthritis affecting one of the tibiofemoral compartments along with the patellofemoral compartment. The bone-and cartilage-preserving features of the iDuo may be especially valuable for young and active patients for whom traditional knee replacement is considered too early, but who suffer from arthritis in one or two compartments. The iDuo allows the patient to preserve their joint for future surgical options, while receiving an implant with the potential to prevent or delay the need for a more invasive surgery. The ConforMIS iDuo is intended for use in patients with severe knee joint pain and disability whose conditions cannot be solely addressed by the use of a prosthetic device that treats only a single knee compartment, such as the unicondylar or patellofemoral prosthesis. The indications for use include restoring joint function and relief of pain due to painful joint disease caused by osteoarthritis, traumatic arthritis, or rheumatoid arthritis of the knee; posttraumatic loss of joint function; and failed osteotomies, hemiarthoplasties, and unicondylar implants. The iDuo may be utilized when the medial or lateral condyle and the patellofemoral areas have been affected by one or more of these conditions. To learn more, contact ConforMIS, Inc. |
Nitinol Implant
| BME (BioMedical Enterprises, Inc.) has launched the Barbed OSStaple™ (BOSS), a nitinol implant designed for internal fixation of bone. The BOSS is an orthopedic nitinol implant with barbs on the legs for bone adhesion. Like the BME OSStaple™ product line, the BOSS nitinol staple changes shape when heated above body temperature to provide compression between 2 bones. The BOSS is ideal for upper and lower extremity procedures, especially when surgeons want the added security of barbed legs to stabilize the implant. Made of nitinol, a biocompatible alloy possessing shape memory and super-elastic properties, the BOSS implant is inserted at room temperature. Using BME’s patented OSSforce™ Implant Controller, the implant is safely heated above body temperature. During this process, the implant’s legs and back change shape to compress bone. In addition, the movement of the legs causes the barbs to anchor more securely in bone. After heating, the nitino |
