Abstract

A two-part implant which is used to provide operative treatment of femoral neck fractures, comprising a sliding screw that has a threaded head on the front end thereof and a bolt which extends beyond the surface of the fracture, whereby a sliding bushing having an inserted thread on the outer periphery thereof is screwed into the other part of the bone. The two-part sliding screw is positioned in a minimally invasive manner. A stop device is arranged in between both parts to ensure that only one part can be displaced axially towards the other in a single direction.

Claims

12GEÄNDERTE CLAIMS [the International Bureau on 25 January 2001 (25/01/01) Received; original claims 1-10 replaced by amended claims 1-8 (2 pages)]
1. Implant for surgical treatment of such. As femoral neck fractures, which is designed as an elongated, at least two-part member whose one part on one part of the bone and whose other part can be anchored in / in / at the opposite, separated by the fracture, other part of the bone, between the two parts of the implant, an arresting device (13, 16) is arranged which only the one part of the implant to another in only the direction allowed, in which the two parts of the implant are subjected to shear an axial displacement and one of the parts the implant as a sliding sleeve (5, 15) is formed and the other part of the implant is designed as a bolt-shaped sliding member, characterized in that the bolt-shaped sliding element is designed as a sliding screw (7,17,27) which (a threaded head at the front free end 8) which can be screwed into one of the bone parts, and that the sliding sleeve (5, 15) at least partially on the outer circumference is provided with a screw thread (20) and can be screwed into the other bone member, said axial Verstellspiel the sliding screw (7,17,27) in the sliding sleeve (5, 15) is selected such that the Gleithüise (5, 15) with its lateral end is not out of the sliding sleeve (5,
15) emerges.
2. The implant according to claim 1, characterized in that the locking device (13, 16) is designed as a ratchet gear.
3. The implant according to claim 2, characterized in that the ratchet gear of a locking ring (13), the radially inwardly at the sleeve (15) is fixed and with an associated, sawtooth Rastzähnung (14, 18) on the outer periphery of the sliding screw (17, 27) cooperates.
4. The implant according to claim 3, characterized in that the Rastzähnung (14) extends over the entire circumference of the bolt (9).
5. The implant according to claim 3, characterized in that the Rastzähnung (14a) extends only partially extends around the circumference of the bolt (9). 13
6. The implant according to claim 3, characterized in that the Rastzähnung as slots (18) formed in the bolt (9).
7. The implant according to one of claims 1 to 6, characterized in that said sliding screw (7, 17, 27) on the outer circumference one or more extending in the axial direction and radially outwardly open cannulas (19).
8. implant for surgical treatment of such. As femoral neck fractures, which is designed as an elongated, at least two-part member whose one part on one part of the bone and whose other part is anchored in / on the opposite, separated by the fracture, other part of the bone in / wherein between the two parts of the implant, an arresting device (13, 16) is arranged, which, characterized by only an axial displacement of a part of the implant to another in only one direction allowed, wherein the implant is formed as intramedullary nail that
Locking means (13, 16) only permits an axial displacement of part of the implant to another in only the direction in which the two parts of the implant are subjected to shear.
