Proximal Humerus System 3.5

Designed to perform.

The Proximal Humerus System 3.5 focuses simplicity without compromising surgical options. The asymmetrical plate shape facilitates straightforward fixation of the greater tubercle. Additionally, the spiral blade option maximizes support of the calcar region. Diverging screw orientation and suture holes complete the offering for stable bone and soft tissue fixation.

Asymmetrical Design

Asymmetrical design supports greater tubercle fixation.

Blades for Calcar Support

Spiral blade to enhance medial support in calcar region.

Drill Guide Blocks

Drill guide block for easy screw insertion of diverging screws.

One System Size 3.5

One screw diameter allows for reduced instrumentation.

Surgical Options

When addressing a fracture pattern that requires additional medial support of the proximal humerus, the plate can be combined with the spiral blade 40° or the spiral blade 50°. These spiral blades provide additional calcar support to the plate-screw-construct in the medial bone tissue. In addition, the long plate (XL) types of the system enable the management of fracture patterns that extend to the humeral shaft.

Highlights

Optional spiral blades reduce the risk of secondary varus displacement of the humeral head by means of enhanced calcar support^[1]
The asymmetrical plate shape and posterior plate holes support the fixation of the greater tubercle
Due to its flat form, the spiral blade has a larger contact surface within the bone than a conventional screw

This prospective study reports on 17 patients with a displaced fracture of the proximal humerus, treated with a APTUS Proximal Humeral Plate 3.5, either with the helical blade to support the calcar, or without it. Patients in this cohort achieved good functional results. The authors found that insertion of the blade significantly reduced the occurrence of seconday varus displacement compared to fixation with the polyaxial plate fixations alone.
