Abstract:
1. An implantable bone fixation system for providing compression between a first exterior bone surface and a second exterior bone surface, the bone fixation system comprising: a first elongated structure comprising a head and a shaft; a washer comprising a rim, the rim shaped to bear against the first exterior bone surface, the washer including a bore, wherein the bore is oblique relative to the rim; a second elongated structure having a proximal end, and terminating at a distal end, and having a longitudinal axis extending between the proximal end and the distal end, and an external diameter perpendicular to the longitudinal axis, wherein the distal end comprises a pair of extensions between which a gap is formed, a pin immovably secured to the distal end; and an anchor rotatably joined to the pin at the distal end of the second elongated structure in the gap, the anchor having a deployed configuration in which a portion of the anchor protrudes beyond the external diameter of the second elongated structure, the anchor shaped to bear against the second exterior bone surface; wherein the shaft of the first elongated structure passes through the bore, is coaxially received in the proximal end of the second elongated structure and is selectively adjustable relative to the second elongated structure to increase or decrease a distance between the washer and the distal end of the second elongated structure to provide a selected level of compression between the first exterior bone surface and the second exterior bone surface.
