Prosthetic support socket for an osseointegrated femoral abutment

An osseointegrated abutment support socket for a residual limb in which an osseointegrated abutment has been implanted is described. The osseointegrated abutment support socket may include a distal socket base assembly, multiple longitudinal struts and a percutaneous site protector. The distal socket base assembly may include a base plate, a collar extending proximally from the base plate and forming a receptacle for receiving a distal end of the osseointegrated abutment, and a strut support ring disposed around the collar. The struts are connected at their distal ends to the strut support ring and extend proximally upward. The percutaneous site protector contacts a distal surface of the residual limb near a percutaneous site where the distal end of the osseointegrated abutment exits the residual limb.
