1. A surgical fixation system, comprising at least one anchoring element with an anchoring portion for anchoring to a bone and with a receiving portion for a stabilization element for connecting to a further anchoring element, wherein the stabilization element is arrangeable in the receiving portion and is fixable therein by a fixing element, wherein the surgical fixation system comprises an abutment element that is arranged on the receiving portion and abuts against the anchoring portion for placement of the stabilization element, wherein the abutment element has at least one deformation region for deforming in dependence on a fixing force of the fixing element acting on the stabilization element,
wherein the abutment element has a deformability,
wherein the abutment element comprises a first abutment element portion having a first deformability, the first abutment element portion facing toward the stabilization element,
wherein the abutment element further comprises a second abutment element portion having a second deformability, the second abutment element portion facing toward the anchoring portion,
wherein the first abutment element portion comprises or forms the at least one deformation region, and
wherein the first deformability is greater than the second deformability as a result of the fixing force.
