Medartis | Ankle Trauma System 2.8/3.5

Designed to perform.

The APTUS Ankle Trauma System 2.8/3.5 provides low profile straight and anatomically precontoured plates for a variety of surgical approaches for treatment of fractures and osteotomies around the ankle.

Anatomical design

The anatomical design of the precontoured plates is based on CT data to accommodate different anatomies.

Anatomical flaps

Flaps in the lateral fibula plates and anterolateral tibia plates allow for capture of the Wagstaffe fragment and Chaput fragment.

Specialized instrumentation

Controlled reduction of the syndesmosis.

TriLock

TriLock locking technology provides multidirectional locking of the screw in the plate.

Approaches

The APTUS Ankle Trauma System 2.8/3.5 is designed for surgical approaches around the ankle including specific MIPO instrumentation.

WEB GL Fibular Anatomic Plate

Highlights

Plate is available with and without flap for Wagstaffe fixation.
20° posterior-anterior oblong hole and single syndesmotic hole for placement of syndesmotic screws or suture button implants (single hole).
Plate position can be adjusted on the bone before final fixation.
Eight screw holes in the distal end of the plate offer fixation options for comminuted fractures or extra fixation in osteoporotic bone.

Features

3.5 TriLock Straight Plates

Highlights

Fibula fractures with syndesmosis injuries can be stabilized using the 2-, 3- and 4-hole 3.5 TriLock straight plates.
Holes are designed to fit the lateral button of a syndesmosis suture implant, allowing the button to sit flush within the plate.

The science behind

Joint-Preserving Surgery in Varus Ankle Osteoarthritis. Alajlan A, Santini S, Alsayel F, Teoh KH, Alharbi W, Puls L, Camathias C, Herrera-Pérez M, Tejero S, Barg A, Wiewiorski M, Valderrabano V. 2022 J Clin Med.

In this paper, Alajlan et al. review the causes and treatment options in varus ankle osteoarthritis, focussing on Joint-Preserving Surgery (JPS). The authors conclude that:" ...JPS is a valuable treatment option in Varus OA, which should not be neglected since it has showed a promising result, optimizing biomechanics and improving the survivorship of the ankle joint."

Joint Preserving Surgery for Valgus Ankle Osteoarthritis. Alajlan A, Valderrabano V. 2022 Foot Ankle Clin.

This review by Alajlan and Valderrabano provides a comprehensive overview of valgus ankle osteoarthritis, including its etiology, clinical presentation, and classification. The authors discuss different treatment options, with a focus on joint-preserving surgical techniques- They conclude that JPS, especially the varisating medial closing-wedge supramalleolar osteotomy of the tibia with solid plate fixation, has been consistently associated with good outcomes for patients with valgus ankle OA.

Large Reduction Forceps

Reduction of the syndesmosis can be achieved using the reduction forceps 230 mm.

MIPO Instrument for Tunnel Preparation

In percutaneus tibia or fibula procedures, the MIPO instrument prepares a path for the plate next to the periosteal tissue.

3.5 Drill Sleeve, Self-Holding

The drill guide or self-holding drill sleeve prevents damage to the screw hole and protects the surrounding tissue from direct contact with the drill. The drill guide also serves to limit the pivoting angle.
