First Claim
1. An internal prosthesis for use with a prosthesis attachable externally to a residual limb having a bone with a free end therein, the internal prosthesis comprising:
- bone end pressure distributing means disposed completely within the residual limb;
open-bottomed bone end containing means attached to the bone end pressure distributing means;
means for reinforcing the bone end pressure distributing means; and
wherein the bone end pressure distributing means comprises a large, flexible, tubular sock/sleeve sized to fit over the muscle tissue of the residual limb and underneath the skin thereof, having a smooth, continuous, reinforced, closed end portion to receive the full force of pressure generated by the free end of the bone.

Abstract
Disclosed is an internal prosthesis for use with a prosthesis attachable externally to a residual limb having a bone with a free end thereof. The internal prosthesis comprises bone end pressure distributing means disposed completely within the residual limb and open-bottomed bone end containing means attached to the bone end pressure distributing means. In separate embodiments, the bone end pressure distributing means comprises a tubular, mesh sock/sleeve with a central aperture. The open-bottomed end containing means comprises a mesh bone sock/sleeve which surrounds the central aperture and extends up the bone disposed around the aperture and also provided with a reinforced portion. Alternatively, the bone end pressure distributing means comprises a radially extending plate with an central aperture around which is disposed an upwardly extending boss. The bone end containing means comprises an open-ended bone cap which is formed of two sections. The first section comprises a portion of bone pins and the second section comprises a boss with a smaller diameter than the first section.
