Intended Use

The APTUS® Titanium Fixation System is intended for use in hand and forearm fractures, osteotomies and arthrodeses.

Device Story

APTUS Titanium Fixation System consists of titanium implant plates and screws for internal fixation of small bones in hand and forearm. Plates available in various shapes (H-frame, straight, T, L) for specific anatomical segments. Screws include TriLock locking screws utilizing spherical three-point wedge locking design for locking plates, and conventional bone screws with double thread design, sharp thread profile, and tapering core diameter. Device used by surgeons in clinical settings to stabilize bone fractures, osteotomies, or arthrodeses. Surgeon selects appropriate plate/screw configuration based on fracture type and anatomical location. Fixation provides mechanical stability to bone segments, facilitating healing and restoring function.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Titanium bone fixation plates and screws. Locking mechanism: TriLock spherical three-point wedge. Conventional screws: double thread design, tapering core, atraumatic tip. Various plate geometries (H, straight, T, L).

Indications for Use

Indicated for hand and forearm fractures, osteotomies, and arthrodeses. Includes management of distal, middle, proximal phalangeal and metacarpal fractures (transversal, spiral, joint-involved, shaft, comminuted, dislocation, avulsion); DIP and PIP arthrodeses; and distal radius fractures (extra-articular/articular extension and flexion) and correction osteotomies via volar or dorsal approaches.

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.

#### 510(k) Summary

# DEVICE DESCRIPTION

The APTUS® Titanium Fixation System consists of implant plates and implant screws and is used for internal fixation of small bones.

#### APTUS Plates

Implant Modules are provided in sizes Hand 1.2, Hand 1.5, Hand 2.0, Hand 2.3 for miplant Modules are pro rised in oristius reconstruction plate system is used for fixation valious iniger segmonts. The distal for corrective osteotomies of the distal radius with of fractures or the under laccess. Variations of plate shapes include H frame, straight, T and L shaped.

#### APTUS Screws

Locking screws for the Radius and Hand 2.0 Lock product lines, designated TriLock™, utilize a spherical three point wedge locking design and are used with locking plates. Conventional bone screws have a double thread design and precisely cut sharp thread profile, tapering core diameter and atraumatic tip. The shorter screws have a small pitch in order to maintain optimal purchase in the bone, while the longer screws have a larger pitch in order to minimize the number of revolutions.

### EQUIVALENCE TO MARKETED PRODUCT

The APTUS® Titanium Fixation System is substantially equivalent in indications and design principles to the following predicate devices, each of which has been determined by FDA to be substantially equivalent to pre-amendment devices: Profyle™ Titanium Hand and Small Fragment System (K961497) from Howmedica (Stryker); Stryker® Leibinger Universal Distal Radius System (K040022) from Stryker Leibinger; and Distal Radius Fracture Repair System (K002775, K023007, K030198) and Fragment Plate System (K041081) from Hand Innovations.
