Fixation system for bones
First Claim
1. A fixation system for bones comprising:
- a connection carrier with at least one passage hole;
at least one bone screw inserted into the at least one passage hole;
the connection carrier including a seat surface and the bone screw including a seat surface, permitting a mutual alignment at various angles for fixing the bone screw at a certain angle to the connection carrier, the bone screw further including a preformed thread below the bone screw seat surface, the preformed thread deforming a portion of the passage hole below the seat surface of the connection carrier when the bone screw is screwed in so that a thread connection is formed between the bone screw thread and the connection carrier, the deformation being formed by rotating the bone screw at a certain angle to the connection carrier.

Abstract
A fixation system for bones including a connection carrier with at least one passage hole and at least one bone screw inserted into the at least one passage hole. The connection carrier including a seat surface and the bone screw including a seat surface, permitting a mutual alignment at various angles for fixing the bone screw at a certain angle to the connection carrier. The bone screw further including a preformed thread below the bone screw seat surface, the preformed thread deforming a portion of the passage hole below the seat surface of the connection carrier when the bone screw is screwed in so that a thread connection is formed between the bone screw thread and the connection carrier, the deformation being formed by rotating the bone screw at a certain angle to the connection carrier.

- 28. A fixation system for bones with a marrowbone nail, comprising at least one passage hole, for bridging bone fragments and at least one locking bolt for screwing into the passage hole and into a bone fragment, in order to connect this to the marrowbone nail, wherein the passage hole has an inner thread for forming a thread into the locking bolt and the locking bolt has a threadless and conical casing region which simplifies the forming of a thread by way of the inner thread at various angles, which reduces the wear and release of swarf and ensures the fixing in the formed-in thread, said casing region having a lower hardness than its core region which ensures the transmission of higher forces.
