OsteoBridge™ Knee Arthrodesis – Standard System

A modular limb preservation system

The OsteoBridge™ Standard System is designed to reinforce the knee joint and bridge bone defects 40-70 mm in length; it can also be used in resection of the metaphyseal region of the femur or tibia.

Treatment using the Standard System involves combining two nails and a single spacer. Defects of lengths in the 40-, 60- or 70-mm range are treated using spacers without flexion angles. Spacers with and without 10° flexion angles are available for treating defects in the 50 mm-length range. The angled spacer can be rotated as needed to adjust the valgus or varus position of the knee.

Indications

– Consequence of an endoprosthesis or joint infection that renders revision/reimplantation of a knee endoprosthesis impossible, or one for which the patient refuses revision/reimplantation
– Tumours in the knee area
Ligamentary loss of the extensor apparatus for which reconstruction is impossible
Post-traumatic defect situations (for which reconstruction via endoprosthesis is not possible)
