Abstract

A winged compression bolt for repairing or fusing bone which is implanted and later removed from bone through a single skin incision. The device includes a central elongated shaft which movably sits in an outer cylindrical tube and supports adjacent one of its ends a pair of wings. A bore is drilled through the bone portions, the device is inserted and the wings are rotated to the horizontal position and compressed against the edge of the outer cylindrical tube and an adjacent bone surface. A securing means is on the opposite end of the central elongated shaft and tightened against the adjacent edge of the outer cylindrical tube and an adjacent bone surface, compressing the bone portions between the securing means and the wings. To remove the device, the securing means is removed, the outer cylindrical tube is removed and the central elongated shaft is pulled through the bore in the bone, causing the wings to rotate from the horizontal to the vertical position and trail the shaft as it is removed from the bore.
