Intended Use

Use of the TIE-IN™ Trapczium may be considered in degenerative or post-traumatic disabilities of the thumb basil joint with: - Localized pain and palpable crepitation during circumduction movement with axial . compression of involved thumb ("grind test") - Decreased motion, decreased pinch and decreased grip strength . - X-ray evidence of arthritic changes of the trapeziometacarpal, trapczioscaphoid, . trapeziotrapezoid, and trapezium second metacarpal joints, singly or in combination - Associated unstable, stiff, or painful distal joints of thumb or swan-neck deformity . The TIF-IN™ Trapezium is for single use.

Device Story

TIE-IN™ Trapezium is a silicone elastomer carpal trapezium prosthesis. It features an hourglass-shaped body for tendon stabilization and a round peg for insertion into the ulnar canal. Offered in three sizes, it is intended for single use in patients with thumb basal joint disabilities. The device replaces the trapezium bone to address pain and functional deficits associated with arthritis. It is implanted by a surgeon in a clinical setting. The device is substantially equivalent to the Swanson Trapezium Implant, utilizing identical materials and design principles.

Clinical Evidence

No clinical data provided; substantial equivalence is based on design and material identity to the predicate device.

Technological Characteristics

Material: Silicone elastomer. Design: Hourglass-shaped body for tendon wrapping; round peg for ulnar canal insertion. Sizes: 3. Sterilization: Not specified. Connectivity: None. Software: None.

Indications for Use

Indicated for patients with degenerative or post-traumatic disabilities of the thumb basal joint exhibiting localized pain, crepitation during grind test, decreased motion/pinch/grip strength, and radiographic arthritic changes of the trapeziometacarpal, trapezioscaphoid, trapeziotrapezoid, or trapezium-second metacarpal joints, with or without associated distal thumb joint instability, stiffness, or swan-neck deformity.

Regulatory Classification

Identification

A wrist joint carpal trapezium polymer prosthesis is a one-piece device made of silicone elastomer or silicone elastomer/polyester material intended to be implanted to replace the carpal trapezium bone of the wrist.
