Intercalary endoprosthesis

An intercalary prosthesis for spanning portions of a long bone, comprising:

• a first intramedullary component having a first stem and a first connector disposed at one end of the first stem, the first stem being configured to be received within an intramedullary canal of a long bone;
• a second intramedullary component having a second stem and a second connector disposed at one end of the second stem, the second stem being configured to be received within the intramedullary canal of the long bone at the same time as the first stem;
• and
• a monolithic connector component having a body and third and fourth connectors disposed at opposed ends of the body,
• wherein the first and third connectors and second and fourth connectors are configured to be locked to each other by radial interference between the connector component and the first and second connectors upon rotation of the connector component relative to the first and second, and wherein the body of the connector component includes a solid shell surrounding a lattice structure.
