The implants of the Alians Forearm range are dedicated to the fixation of radius and ulna fractures and osteotomies in adults.
Positive ulnar variance may be constitutional or post-traumatic following a distal radius fracture. It results from a relative lengthening of the ulna compared to the radius. When symptomatic, this anomaly can lead to ulnocarpal impaction, characterized by overload of the ulnar-sided wrist structures. It is a frequent cause of pain and may result in decreased grip strength.
One of the surgical treatments consists of performing a diaphyseal ulnar shortening osteotomy and stabilizing the correction with a stable osteosynthesis system using a locked plate.
The Alians Ulna 3.3 range offers a complete system of plates and associated cutting guides designed to perform ulnar shortening osteotomies. All implants and instruments are gathered in a single kit.
A simple and effective solution
for ulna shortening osteotomies.
This plate model, symmetrical and anatomical, is designed for the stabilization of ulna osteotomies. It includes three Ø3.5 mm screws on each side of the osteotomy site, in both the distal and proximal parts, as well as a Ø2.8 mm transfixing screw crossing the site to maintain it under compression.
The associated cutting guide is modular, to match the shortening value defined for the osteotomy (from 2 mm to 6 mm). It is designed to perform oblique cuts, allowing for a larger interosseous contact surface during the healing phase.
The implant is compatible with three different surgical approaches: palmar, dorsal, and lateral.
The system is equipped with a cannulated rack handle, allowing for effective and intuitive compression.
This mechanism facilitates closing the osteotomy site once the cuts are made, while maintaining the alignment of the bone fragments.
