Abstract
A surgical kit suitable for repair of articular surfaces in the talocrural joint, includes: a surgical implant having a cap with an outer surface conforming to a talus dome surface and an inner surface having a central implant anchoring peg extending perpendicularly from said inner surface, a hollow tubular shell suitable for correct pre-drilling for implantation of the surgical joint implant in the dome of the talus, and a saw guide conforming and fixable to the lower portion of the tibia and providing saw guide surfaces in at least one plane, suitable for osteotomy of a lower portion of a tibia to expose the dome of the talus.
Claims9
A surgical kit suitable for use in osteotomy surgery for repair of articular surfaces in the talocrural joint, comprising:
- a surgical implant with an outer surface conforming to a talus dome surface;
- a hollow tubular shell suitable for correct pre-drilling for implantation of the surgical joint implant in the dome of the talus;
- and
- a saw guide conforming and fixable to the lower portion of the tibia and providing a saw guide surface in one plane, suitable for osteotomy of a lower portion of a tibia to expose the dome of the talus, wherein the saw guide is adapted to conform to the lower medial anterior portion of the tibia and is configured to provide for a saw cut in one plane for severing a portion of the malleolus to gain access to the medial portion of the talus dome, and wherein the saw guide is configured to provide for said saw cut in one plane to temporarily expose the dome of the talus by the saw cutting out of a tibia piece in the temporary osteotomic removal of a distal portion of the tibia for implantation of the surgical implant in the dome of the talus.
