| 摘要 |
The invention relates to a prosthetic body for an upper leg prosthetic comprising a shaft (5, 5a, 5b) having a proximal support plate (4) for a prosthetic head (15), wherein at least two proximally spaced and distally converging shaft posts (5a, 5b) are mounted on the support plate (4), descending below the same and connected by struts (6), particularly diagonal struts (6), and wherein cavities (12), and/or free open regions (12) are formed between the shaft posts (5a, 5b) and the struts (7), into which spongy bone can grow, wherein at least the lower connecting area of the support plate (4) whereon the shaft posts (5a, 5b) are mounted is disposed horizontally, the support plate (4), extending medially over the cross section of the shaft (5, 5a, 5b), immediately below the connection areas, and the support plate (4) transitioning ventrally and dorsally into the shaft (5, 5a, 5b) without protruding. The invention further relates to a rasp instrument for a prosthetic body and a vibration device for generating mechanical vibrations in order to induce the same in the prosthetic body.
