Intended Use

The Wristore Fixator is intended to provide external fixation of the upper extremity. External fixation devices allow for three plane (axial, AP & medio/lateral) control over fractures and bone segments.

Device Story

Wristore Fixator; external fixator for upper extremity fractures. Inputs: bone segments requiring stabilization. Operation: surgeon places K-wires and fixation pins into bone; polyetherimide resin external frame attached and tightened to stabilize fracture; provides three-plane (axial, AP, medio/lateral) control. Output: stabilized bone segments. Used in clinical/surgical settings by physicians. Benefits: fracture stabilization via external fixation. Supplied non-sterile; requires steam sterilization before use. Uses standard orthopaedic instrumentation for placement and adjustment.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on design, material, and intended use comparisons to legally marketed predicate devices. Bench testing validated the cleaning protocol and steam sterilization cycle (250° F for 30 minutes) in accordance with AAMI ST32 Method 3, Protocol B.

Technological Characteristics

Materials: medical grade polyetherimide resin (frame), instrument grade stainless steel (instruments/pin guides), implant grade 316L stainless steel (pins/K-wires). Design: single frame, transfixing pin-based external fixator. Connectivity: none. Sterilization: non-sterile, requires steam sterilization (250° F, 30 min).

Indications for Use

Indicated for patients requiring external fixation for Colles, mid, and proximal fractures of the upper extremity.

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.

Predicate Devices

• Colles C Series Frame Sterile Pack (K003397)
• Articulating Distal Radius Fixator (K984498)

#### Substantially Equivalent Device(s):

Millennium Medical Technologies, Inc. believes that the Wristore is substantially equivalent to the following legally marketed upper extremity external fixators marketed by DePuy, Inc and Synthes, Inc. respectively.

- K003397, Colles C Series Frame Sterile Pack. ●
- K984498, Articulating Distal Radius Fixator. ●

Both referenced equivalent fixators are legally marketed. Both fixators have the same indications for use as the Wristore and, in the case of the Synthes fixator, is made from the identical material. All three systems utilize the same type of fixation pins. All three systems are clinically equivalent in terms of design, materials, indications, cautions, precautions and adverse events. A feature comparison chart is included at the end of the summary that graphically depicts substantial equivalence.

#### Description of the Device:

The materials utilized for the construction of the external elements of the Wristore Fixator are medical grade polyetherimide resin. This material is the identical material utilized to construct the Articulating Distal Radius Fixator (K984498). The materials utilized in the instruments and pin guides are instrument grade stainless steel. The pins and K-wires used to fix the fractured bones are produced from implant grade stainless steel (316L). The Wristore Fixator utilizes legally marketed commercially available fixation pins and/or K-wires. Once the provided K-wires and pins have been properly placed, the poly-resin external frame is tightened and the fracture(s) stabilized. Typical orthopaedic instrumentation is provided to place, tighten and adjust the fixator.
