• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3030
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Avanta carpal fusion plate is designed for fusion of the carpal bones of the hand including; capitate, hamate, and triquetrum. The fusion plate is intended for use in patients suffering from pain and/or loss of function due to osteoarthritis, post-traumatic arthritis, fractures, revision of failed partial wrist fusions, carpal instability, or rheumatoid arthritis. The fusion plate is used in conjunction with screws that fix the plate to the carpal bones of the hand.

Device Story

Low-profile, single-piece metallic plate designed for dorsal carpal bone fixation; features spherical holes/slots for bone screws. Used by orthopedic surgeons in clinical settings to stabilize and fuse carpal bones (capitate, hamate, lunate, triquetrum). Provides mechanical stabilization to facilitate bone fusion; addresses patient pain and functional loss from arthritis, fractures, or instability. Output is a physical construct providing rigid fixation; clinical decision-making relies on surgeon assessment of patient pathology and radiographic evidence.

Clinical Evidence

No clinical data provided; substantial equivalence based on design characteristics and intended use comparison to predicate devices.

Technological Characteristics

Implantable grade stainless steel; low-profile plate with spherical holes/slots for bone screws; single-piece construct; mechanical fixation; non-sterile (implied, requires sterilization); no software or electronic components.

Indications for Use

Indicated for patients with pain or loss of function due to osteoarthritis, post-traumatic arthritis, fractures, failed partial wrist fusion revision, carpal instability, or rheumatoid arthritis requiring fusion of carpal bones (capitate, hamate, lunate, triquetrum).

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.
