Abstract
The present disclosure relates to a system for the fixing of bone segments or bone fragments comprising an implant plate or an implant surface plate having a bore or a cut-out and comprising an implant screw which can be guided through the bore or cut-out of the plate, wherein the implant screw has a screw shaft and a screw head and wherein both the screw shaft and the screw head have a thread with identical pitches.
Claims18
A system for the fixing of bone segments or bone fragments comprising:
- an implant plate or an implant surface plate having a bore or a cut-out;
- and
- an implant screw which can be guided through the bore or cut-out of the plate, wherein the implant screw has a screw shaft and a screw head, wherein both the screw shaft and the screw head have a thread with identical pitches, wherein the screw head has a larger outer thread diameter than the screw shaft, wherein the bore or cut-out of the plate is provided with an internal thread and the thread of the screw head is able to engage the internal thread of the bore or cut-out of the plate, wherein an outer thread diameter of the screw shaft is less than an inner thread diameter of the bore or cut-out of the plate so that the implant screw is initially screwed through the bore or cut-out of the plate without any connection to the plate, and wherein a thread height in a region of the screw head is smaller than a thread height in a region of the screw shaft.
A bone fixation system for the fixing of bone segments or bone fragments comprising:
- an implant plate or an implant surface plate having a bore or a cut-out;
- and
- a bone implant screw which can be guided through the bore or cut-out of the plate, wherein the bone implant screw has a screw shaft and a screw head, wherein both the screw shaft and the screw head have a thread with identical pitches, wherein the screw head has a larger outer thread diameter than the screw shaft, wherein the bore or cut-out of the plate is provided with an internal thread and the thread of the screw head is able to engage the internal thread of the bore or cut-out of the plate, wherein an outer thread diameter of the screw shaft is less than an inner thread diameter of the bore or cut-out of the plate so that the implant screw is initially screwed through the bore or cut-out of the plate without any connection to the plate, and wherein a thread height in a region of the screw head is smaller than a thread height in a region of the screw shaft.
