Wright Swanson Basal Thumb Implant 4283001, Size 1, Silicone Arthroplasty

Wright Swanson Basal Thumb Implant | Silicone Arthroplasty | 4283001

The Wright Swanson Basal Thumb Implant (4283001) is a precision-engineered orthopedic solution designed for 2026 standards in hand reconstruction. Specifically developed for the treatment of severe osteoarthritis or rheumatoid arthritis of the trapeziometacarpal (TM) joint, this Size 1 silicone elastomer spacer acts as an internal cushion to restore joint space, alleviate pain, and maintain functional mobility of the thumb.

Based on the clinically proven Swanson design, this implant provides a stable yet flexible interface that mimics the natural pivot-point of the basal joint, significantly improving the patient's grip strength and manual dexterity.

Key Performance Features

• Medical-Grade Silicone Elastomer: Constructed from a high-performance, biocompatible silicone that offers the ideal balance of compressive strength and flexibility, ensuring long-term durability under the repetitive stresses of thumb movement.

• Anatomical Contouring: The implant geometry is designed to seat securely within the prepared base of the first metacarpal, providing a stable "buffer" that prevents bone-on-bone contact with the trapezium.

• Size 1 Optimization: Specifically sized for smaller anatomical profiles, ensuring a precise fit that minimizes the risk of implant migration or subluxation post-surgery.

• Biomechanical Stability: Effectively restores the longitudinal height of the thumb ray, preventing the "radial drift" and shortening often associated with advanced basal joint degeneration.

• Radiopaque Properties: The material is easily visualized under fluoroscopy or standard X-ray, allowing the surgeon to verify exact intraoperative placement and monitor long-term positioning.
