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.
