The present invention refers to a device for the resection of bones (1) for preparing the attachment of an endoprosthesis to the joints which consists of at least two joint elements cooperating with each other, comprising at least one tool guide (3, 4, 5, 7, 14) and at least one support (6, 9, 10, 1
The present invention refers to a device for the resection of bones (1) for preparing the attachment of an endoprosthesis to the joints which consists of at least two joint elements cooperating with each other, comprising at least one tool guide (3, 4, 5, 7, 14) and at least one support (6, 9, 10, 15, 21) suitable for orienting the at least one tool guide (3, 4, 5, 7, 14), wherein, either in the immediate vicinity of the joint and/or across joints, the at least one support (15, 21) enables the at least one tool guide (3, 4, 5, 7, 14) to be oriented and positioned on a further joint element, or enables the at least one tool guide (3, 4, 5, 7, 14) to be oriented and positioned at the same joint element distally to the area to be treated and/or outside the surgical area. The at least one tool guide (3, 4, 5, 7, 14) and the at least one support are preferably immovably connected to each other so as to manufacture an individual single-use template. The invention also relates to a method for manufacturing such a device or template, an endoprosthesis suited for this purpose, a method for manufacturing such an endoprosthesis, and a surgical set consisting of said parts.
1. A device for preparing a bone for an implant comprising: a support portion comprising a plurality of elongate elements shaped as a reproduction according to corresponding elongate surface structures of the bone from a three-dimensional image of the bone, the plurality of elongate elements arrange
1. A device for preparing a bone for an implant comprising: a support portion comprising a plurality of elongate elements shaped as a reproduction according to corresponding elongate surface structures of the bone from a three-dimensional image of the bone, the plurality of elongate elements arranged to form cavities that can engage anatomy of the bone; anda tool guide portion attached to the support portion, the tool guide portion including a first tool guide oriented and positioned by the support portion to prepare an area of the bone for receiving an implant. 2. The device of claim 1, wherein the plurality of elongate elements includes a first plurality of spaced-apart sagittal elements and a second plurality of spaced-apart coronary elements forming a grid. 3. The device of claim 2, wherein the first tool guide includes a planar surface configured to guiding a resection of the bone along a plane for receiving an implant. 4. The device of claim 2, wherein the tool guide portion includes a plurality of tool guides. 5. The device of claim 2, wherein the tool guide portion includes a second tool guide configured for guiding fixation elements. 6. The device of claim 2, wherein the device is a tibial template and further comprising a support surface for a tibial bone, the support surface spaced apart from the support portion and attached to the support portion with an elongated bridge element. 7. The device of claim 2, wherein the device is a femoral template and includes a pair of lateral brackets supporting the coronary elements. 8. The device of claim 2, wherein the device is a tibial template and the support portion is shaped as a reproduction of a femoral knee implant. 9. The device of claim 2, wherein the sagittal elements are substantially parallel. 10. The device of claim 2, wherein the coronary elements are substantially parallel. 11. The device of claim 2, wherein the sagittal elements are substantially parallel and perpendicular to the coronary elements. 12. A device for preparing a bone for an implant, comprising: a support portion including a plurality of elongate elements shaped as a reproduction according to corresponding elongate surface structures of the bone from a three-dimensional image of the bone;a first tool guide portion including a first sagittal tool guide and a second sagittal tool guide, the first and second sagittal tool guides parallel to each other and configured to cut a sagittal area of the bone;a second tool guide portion including a coronary tool guide, the coronary tool guide being substantially perpendicular to the first and second sagittal tool guides; anda third tool guide portion including a transverse tool guide, the traverse tool guide being substantially perpendicular to the first tool guide portion and the second tool guide portion. 13. The device of claim 12, wherein the plurality of elongate elements are arranged to form at least one viewing opening through the device between adjacent elongate elements. 14. The device of claim 12, further comprising a bridge extending from one of the first, second or third tool guide portions. 15. The device of claim 14, wherein the bridge extends from the transverse tool guide away from the first and second sagittal tool guides substantially parallel to the coronary tool guide. 16. The device of claim 15, wherein the bridge includes a supporting surface area for engaging a portion of a lower leg. 17. The device of claim 12, further comprising a tibia plate extending from the support portion and comprising a support configured to engage a front edge of a tibia. 18. The device of claim 12, further comprising lateral tailoring of one of the first, second or third tool guide portions configured to retract the one of the first, second or third tool guide portions from bone to avoid soft tissue engagement of the device. 19. The device of claim 12, further comprising: a fixation guide extending along the coronary tool guide; anda plurality of support surfaces disposed along the fixation guide and shaped to engage corresponding surfaces of a resected femur. 20. The device of claim 12, further comprising a pair of sagittal canals extending along the transverse cutting guide. 21. The device of claim 12, further comprising an endoprosthesis connected to the support portion. 22. The device of claim 21, wherein the endoprosthesis comprises a reproduction of a femur prosthesis. 23. The device of claim 12, further comprising a pair of insertion-style plates extending from the transverse tool guide and configured to be inserted into horizontal tibia resection gaps. 24. The device of claim 12, wherein the plurality of elongate elements are arranged to form cavities that can engage anatomy of the bone. 25. The device of claim 12, wherein each of the plurality of elongate elements is elastic.
