1 Transcutaneous, Distal Femoral, Intramedullary Attachment for Above-the-Knee Prostheses: An Endo-Exo Device by Horst Heinrich Aschoff, Robert E. Kennon, John M. Keggi, and Lee E. Rubin J Bone Joint Surg Am Volume 92(Supplement 2):180-186 December 1, 2010 ©2010 by The Journal of Bone and Joint Surgery, Inc.

2 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. Horst Heinrich Aschoff et al. J Bone Joint Surg Am 2010;92:180-186 ©2010 by The Journal of Bone and Joint Surgery, Inc.

3 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;92:180-186 ©2010 by The Journal of Bone and Joint Surgery, Inc.

4 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;92:180-186 ©2010 by The Journal of Bone and Joint Surgery, Inc.

10 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;92:180-186 ©2010 by The Journal of Bone and Joint Surgery, Inc.

11 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;92:180-186 ©2010 by The Journal of Bone and Joint Surgery, Inc.
