Abstract:
1. A fracture compressive system comprising: a sleeve comprising a proximal sleeve portion and a distal sleeve portion, wherein the sleeve is configured to contact a first bone portion, wherein the sleeve includes a surface which forms a ridge on the inside surface of the sleeve; a stop cap; a shaft comprising a distal shaft portion, a proximal shaft portion, and a body portion, wherein an exterior of the distal shaft portion is configured to anchor into a second bone portion, wherein the proximal shaft portion of the shaft is received within the sleeve such that shaft and sleeve move longitudinally relative to one another, wherein the stop cap attaches to the proximal shaft, wherein the shaft includes a flat surface such that the ridge impacts a distal portion of the stop cap to limit the outward longitudinal movement of the shaft and the ridge impacts a distal portion of the flat surface to limit the inward longitudinal movement of the shaft; and a compressive device engaged between the sleeve and the shaft, wherein the proximal end of the sleeve comprises a recessed region comprising a ledge, wherein the compression device has one end abutting the ledge, and wherein the compressive device is configured to shorten in direct relationship with collapse of the shaft relative to the sleeve, and wherein the shaft, the sleeve and the compressive device cannot move rotationally relative to one another.
