Abstract

A bone loss plate for the rigid fixation of a bone having a bone gap where portions of the bone are absent, the plate includes an elongated fixation plate having a first plate side, a second plate side, a proximal portion, a distal portion, and a middle portion and a tubularly-shaped containment cage connected to the second plate side of the elongated fixation plate, the tubular containment cage having a length shorter than the elongated fixation plate.

Claims (5)

1. A bone loss plate for the rigid fixation of a long bone having a bone gap where portions of the bone are absent, the plate comprising:

an elongated fixation plate having a cage aperture located in a middle portion of the fixation plate, a first end for fixation to the long bone on one side of the bone gap, a second end for fixation to the long bone on the opposite side of the bone gap; and

a tubularly-shaped containment cage forming a circumferential cage wall with a first open end, a second open end and a plurality of cage wall openings, the circumferential cage wall connected to the middle portion of the fixation plate wherein the cage aperture of the fixation plate communicates with an interior of the containment cage to permit the addition of osteogenic bone material to the interior of the containment cage after the containment cage of the bone loss plate is positioned within the bone gap of a bone and the fixation plate is secured to the bone having the bone gap, the containment cage having the first and second open ends shaped similar to the cross-sectional shape of the long bone at the bone gap wherein the tubularly-shaped containment cage is expandable along a longitudinal axis that is parallel to a longitudinal axis of the fixation plate.

2. The plate of claim 1 wherein the long bone is selected from the group consisting of a tibia, a femur, a fibula, a humerus, a radius, and an ulna.

3. The plate of claim 1 wherein the circumferential cage wall has one or more cage braces extending across one of the first open end, the second open end or both of the tubularly-shaped containment cage.
