Duocentric Expert Trauma
Product catalog summary
Indications: The DUOCENTRIC Trauma prosthesis is designed for shoulder arthroplasty in cases of complex proximal humerus fractures, specifically 3 or 4 part fractures.
Materials: The prosthesis is made from stainless steel (ISO 5832-9).
Principles: The prosthesis aims to reconstruct the geometry of the proximal humerus to restore normal joint kinematics. Proper tuberosity fixation is crucial for stability and longevity, preventing issues like stem migration and shoulder dysfunction. The prosthesis allows for suturing of the greater and lesser tuberosities using a tension band technique, reducing fractures to a 2-part configuration.
Implant Characteristics: The DUOCENTRIC Trauma Prosthesis includes two implant designs: a trauma humeral head with a perforated rim for osteo-sutures and a humeral stem with a T-shaped cross-section to counteract rotational forces. The cervico-diaphyseal angle is 140°. The head and stem are connected with a removable screw, allowing for head exchange and compatibility with both standard anatomic and reversed prostheses.
Sizes and References: Humeral heads are available in diameters of 40, 44, and 50 mm. Humeral stems come in various lengths, both anatomical and cemented, with specific reference numbers provided for each size.
Manufacturer: The prosthesis is manufactured by SGM and Aston Médical, located in Saint Etienne, France, and complies with ISO 13485 standards.

Trauma Indications Shoulder arthroplasty for complex fractures of the proximal humerus (3 or 4 part fractures). Raw materials : ■ Stainless steel (Iso 5832-9) Principles : The geometry of the proximal humerus should be reconstructed to restore normal joint kinematics. Changes in ligament tension and rotator cuff balance due to malplacement of tuberosity fixation may lead to stem migration, shoulder dysfunction and progressive wear of the bearing surface. ■ The optimal position for tuberosity fixation is therefore a determining factor in the stability and longevity of a trauma shoulder prosthesis.
