Medacta® Shoulder for Surgeons

The Medacta Shoulder System is a modular solution that features a broad range of options, including wide-ranging sizes, adjustable offset and innovative configurations both in the anatomic and in the reverse configuration.

The Medacta Shoulder System provides 2 stem options, standard and short, 3 humeral inclination options for TSA (128 º /135 º /142º) and 2 for RSA (145° and 155°), 4 sizes for RSA glenosphere and 10 cemented pegged glenoid for TSA for an optimized mismatch.

The Medacta Shoulder System offers the flexibility to move from a total to a reverse arthroplasty, without the need to revise all components. The aim is to have conversions rather than revisions of the all prosthesis components.

Composed of innovative components, the design of which has been based on the most recent research in shoulder replacement the system is compatible with, and can be further enhanced by, the CT-based MyShoulder 3D preoperative planning solution, offering patient-specific humeral and glenoid guides.

Humeral Stability

The humeral diaphysis has a self-centering and self-orienting shape. The calcar design has been optimised, through extensive trialing using 3D imaging and cadaver analysis, and delivers enhanced primary stability. Achieving a precise fit between stem and humeral canal is made possible with the extensive size range available with this system.

Reverse Configuration Improvements

With an innovative design of the liner, the surgeon has the opportunity to adapt the system to the patient’s conditions by potentially increasing joint ROM (145° humeral inclination) and maximizing joint stability (155° humeral inclination). The glenosphere has a lateral offset (4 mm) and also an inferior offset (2 mm) to reduce the risk of scapular notching. The complete hemispherical design delivers stability through full ROM.

Anatomic Configuration Improvements

The surgeon has the opportunity to ideally match and reproduce the head-stem offset using the double eccenter-head. This option delivers an adjustable head eccentricity between 0 and 5 mm. The Medacta Shoulder System provides 3 anatomical metaphysis inclination options (128° / 135° / 142°) to match the pre-operative humeral inclination.

Ideal Platform for conversion from TSA to RSA

In case of revision, the humeral diaphysis remains in place and is used to receive the reverse metaphysis and the reverse liner. This is a less invasive revision surgery option but continues to deliver satisfactory stability of the prosthesis.
