Wrist Spanning and Fusion

The Avanti Wrist & Forearm System contains meticulously designed and manufactured implants to address the variety of wrist pathology encountered by today’s surgeons. The Spanning and Fusion plates are very low profile to facilitate application and reduce soft tissue complications. Far-cortical locking screws reduce construct rigidity to reduce stress shielding and promote rapid bone healing. Additionally, the Wrist & Forearm System contains all you may need to address associated injuries including fractures of the radius, ulna and carpal bones. Move forward with Avanti!

Wrist Spanning and Fusion (single page version)Wrist Spanning and Fusion (double page version)

01

Bridge/Spanning plate for severe comminution, complex ligamentous injuries, expeditious rigid fixation or prolonged unloading of the wrist.

Separate incisions over the 2nd metacarpal and over the intersection of the thumb outcroppers and the wrist extensors, or a single extensile dorsal approach

02

Plate designed for ease of insertion and to fit comfortably in the 2nd dorsal compartment.

Passed from distal to proximal within the 2nd dorsal compartment or from proximal to distal under the outcroppers.

Secured first to the 2nd metacarpal and then to the radial metadiaphysis.

To be used as temporary fixation.

Removed usually at approximately 10 weeks post-operatively.

03

Pre-contured wrist fusion plates in standard and short bends as well as straight configurations.

Designed to be applied to the 3rd metacarpal and the radial metadiaphysis.

Tapered for ease of insertion and to reduce stress concentration at ends of the plate.

Low-profile to reduce hardware prominence and soft tissue irritation.

Cartilage and subchondral bone adjacent to the 3rd carpometacarpal, capitolunate and radiolunate (or radiocaptiate in case or prior /concomitant PRC) joints must be removed to expose cancellous bone

04

Excised carpal bones or distal radius (such as the dorsal distal radius) may be used as supplemental bone graft.

Plate is applied to the metacarpal first to insure correct plate positioning.

Screw placement with a bicortical non-locking screw in the oblong hole.

Axial compression is applied with the Dynamic.

Device prior to final fixation A variety of 2.7mm fasteners are available to obtain secure fixation

05

Cannulated, headless screws for carpal reconstruction and fragment-specific fixation.

Designed for ease of insertion, compression and secure fixation.

Suitable for partial wrist fusions, carpal fracture fixation, distal radius fragment fixation and distal ulna fracture fixation Intuitive, standard cannulated technique.
