OsteoBridge™ Knee Arthrodesis – Extended Plus System

A modular limb preservation system

The OsteoBridge™ Extended Plus System is designed to stiffen the knee joint and bridge bone defects 80-140 mm in length; it can also be used in resection of the metaphyseal region of the femur or tibia.

The Extended PLUS System is used for large-area restorations; it is made up of two spacers which are connected via a spacer connector and two nails. Two straight spacers or one straight spacer and one 10° angled spacer can be used for this configuration. The angled spacer can be rotated as needed to adjust the valgus or varus position of the knee. Defects between 80 mm and 140 mm in length can be treated using the Extended PLUS system.

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)
