Abstract

A device for containing bone graft material includes a mesh outer sleeve extending longitudinally from a proximal end to a distal end and sized and shaped to correspond to a profile of an outer surface of a target bone. The outer sleeve includes a longitudinal slot extending along a length thereof. The device also includes a mesh inner sleeve connected to an interior surface of the outer sleeve via at least one strut so that a bone graft collecting space is defined therebetween. The inner sleeve is sized and shaped to correspond to a profile of a medullary canal of the target bone. In addition, the device includes an interstitial mesh extending radially away from an exterior surface of the inner sleeve toward an interior surface of the outer sleeve to hold graft material in the bone graft collecting space.

Claims11

Dependent claims

A method for treating a bone with bone graft material, comprising:

opening a mesh outer sleeve of a bone graft containment device by separating longitudinal edges defining a longitudinal slot extending therealong;
packing a bone graft material into an interstitial mesh extending radially away from an exterior surface of a mesh inner sleeve toward the interior surface of the outer sleeve so that the bone graft material is packed against the exterior surface of the inner sleeve, an exterior surface of the interstitial mesh separated from an interior surface of the mesh outer sleeve so that, when the longitudinal edges are separated, the outer sleeve is moved away from the interstitial mesh, the inner sleeve connected to the outer sleeve via at least one strut so that a bone graft collection space is defined therebetween;
positioning the device so that the inner sleeve and interstitial mesh extend in a target area between separated portions of a target bone to be treated and the outer sleeve overlaps ends of the separated portions;
and
closing the outer sleeve so that the device is mounted over the target bone.
