The Endo-Exo-Femurprosthesis is a transcutaneous, press-fit distal femoral intramedullary device with the distal, external aspect serving as a hard point for attachment of an above-the- knee prosthesis.

The device is a porous modular construct with a smoothly polished coupler exiting distally through the skin. Horst Heinrich Aschoff et al. J Bone Joint Surg Am 2010;92: ©2010 by The Journal of Bone and Joint Surgery, Inc.
At least 12 to 15 cm of distal femoral bone is needed for adequate bone stock for implantation of the intramedullary device. Horst Heinrich Aschoff et al. J Bone Joint Surg Am 2010;92: ©2010 by The Journal of Bone and Joint Surgery, Inc.

Fig. 6 A quick-disconnect coupler can be used if desired, and essentially any type of external prosthesis may be employed. Horst Heinrich Aschoff et al. J Bone Joint Surg Am 2010;92: ©2010 by The Journal of Bone and Joint Surgery, Inc.
Partial weight-bearing can begin as early as two to three weeks after the stoma procedure. Horst Heinrich Aschoff et al. J Bone Joint Surg Am 2010;92: ©2010 by The Journal of Bone and Joint Surgery, Inc.

The device is coupled to a leg prosthesis, with a very functional transfer of the load across the prosthesis. Horst Heinrich Aschoff et al. J Bone Joint Surg Am 2010;92: ©2010 by The Journal of Bone and Joint Surgery, Inc.
