The Cartiva Implant, also known as Cartiva Synthetic Cartilage Implant (SCI), is a medical device used primarily in the treatment of osteoarthritis of the big toe, a condition known as hallux rigidus. Here's an overview:
Purpose
Treatment of Hallux Rigidus: The Cartiva Implant is designed to relieve pain and improve function in patients suffering from arthritis in the big toe joint.
Design
Material: The implant is made from polyvinyl alcohol (PVA) hydrogel, a biocompatible material that mimics the properties of natural cartilage.
Structure: It has a porous structure, allowing tissue ingrowth, which helps to anchor it in place within the bone.
Procedure
Implantation: The implant is inserted into the metatarsophalangeal (MTP) joint of the big toe. This is done through a minimally invasive surgical procedure.
Bone Preparation: A small hole is drilled into the metatarsal head, where the implant is placed to act as a cartilage replacement.
Benefits
Pain Relief: Reduces pain associated with arthritis in the big toe.
Range of Motion: Preserves and may even improve the range of motion of the joint compared to traditional treatments like joint fusion.
Minimally Invasive: The procedure is less invasive than traditional joint fusion surgeries, leading to quicker recovery times.
Alternatives
Conservative Treatments: Orthotics, physical therapy, pain medications.
Surgical Alternatives: Joint fusion (arthrodesis), joint replacement (arthroplasty), cheilectomy (removal of bone spurs).
Outcomes
Success Rate: Studies have shown positive outcomes in terms of pain relief and function, with many patients experiencing significant improvements.
Longevity: While the Cartiva Implant provides a promising alternative to joint fusion, long-term studies are ongoing to fully understand its durability and long-term benefits.
Considerations
Suitability: Not all patients are candidates for the Cartiva Implant. Factors such as the severity of arthritis, bone quality, and patient activity levels are considered.
Potential Complications:** As with any surgical procedure, there are risks, including infection, implant displacement, or continued pain.
Regulatory Status
FDA Approval: The Cartiva SCI received FDA approval in 2016, indicating it has been evaluated for safety and efficacy in the treatment of hallux rigidus.
The Cartiva Implant represents a significant advancement in the treatment of hallux rigidus, offering an alternative that maintains joint mobility and has a quicker recovery time compared to traditional fusion surgeries.
