Intercalary prosthesis, kit and method

摘要

An intercalary prosthesis spans a space in the shaft of a long bone between native proximal and distal ends of the long bone. The intercalary prosthesis has first and second intercalary segments connected to proximal and distal stem components. The stem components are implanted in the proximal and distal ends of the long bone. One of the intercalary segments has a male dovetail and the other has a female dovetail. The male and female dovetails are positioned to allow the male dovetail to be moved into the female dovetail in a direction other than the proximal-distal direction. The intercalary segments can thus be connected after the segments have been implanted without damaging the soft tissue at the native bone through distraction. The intercalary segments and stem components are provided as part of a kit. The method of implanting the intercalary prosthesis is also disclosed.
