The Ascension Silicone MCP is a single-component metacarpophalangeal silicone spacer consisting of proximal and distal intramedullary stems and a central flexible hinge of 30 deg. It is provided sterile and available in five sizes. Guided osteotomies are made first to the metacarpal head and then the proximal phalanx base. The medullary canals are then progressively broached to the desired size. The phalanx is broached first because it generally determines the sizing of the implant. Trial implants are then inserted, and the joint is reduced. Once the trial reduction is satisfactory, the trial implants are removed, and the final implants are inserted.The efficient choice for small joint replacement technology, the Ascension Silicone MCP features a similar design to our PyroCarbon MCP and utilizes the same instrumentation for intra-operative flexibility. The intramedullary alignment awl accepts a uniquely designed parallel external alignment guide providing an accurate visual alignment reference along the bone axis.
