The Ascension PyroCarbon MCP is a metacarpophalangeal total joint replacement consisting of separate proximal and distal components. The proximal component replaces the metacarpal head and the distal componentreplaces the base of the proximal phalanx. It is available in five sizes. Intramedullary stems stabilize both components. Components are implanted using a press-fit technique. Guided osteotomies are made first to the metacarpal head and then the phalangeal base. Next the medullary canals are progressively broached to the desired size. The phalanx is broached first because it generally determines the sizing of the implant. Trial implantsare then inserted, and the joint is reduced. Once the trial reduction is satisfactory, the trial implants are removed, and the final implants are impacted into place.
The Ascension MCP System is the only total system on the market with two implant options: a two component anatomical total joint replacement made out of biocompatible pyrocarbon and a one component Silicone Spacer.
Both implants use the same colored coded instrumentation giving your surgeons an intra—operative choice. The MCP system consists of five sizing options with colored coded instrumentation. Components are press fit eliminating the need for cement.
