Abstract
A bone fixing blade (2), which is fixed at a intermedullary nail main body (1) to be inserted into a medullary space of a fractured thighbone and which fixes a big bone piece portion (B1) and a small bone piece portion (B2) composing the thighbone, is provided with a cut-out portion forming unit (231) formed in a stick-like shape along a circumferential direction of the bone fixing blade comprised of three cut-out portions (23a) cut out from the surface toward the inside, wherein the cut-out portion forming unit (231) is pressed into the inside of each of the big bone piece portion and the small bone piece portion to be in a position on a recess side that is deeper than a bone fracture line (L).

9. A bone fixing component attached and fixed to an intramedullary nail main body insertable in a medullary cavity of a fractured thighbone to fix a first bone piece portion and a second bone piece portion different from the first bone piece portion composing the thighbone, the bone fixing component comprising:
-
a form formed in a shaft shape and having a longitudinal direction; and at least one a cut out section area provided with at least one cut out section, the cut out section formed along a direction which crosses with the longitudinal direction of the bone fixing component and cut out from an outer surface toward an inner side, wherein the bone fixing component is insertable into an inner side of each of the first bone piece portion and the second bone piece portion so that the cut out section area is inserted first so that it extends deeper into the bone portions than the remainder of the bone fixing component. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A thighbone fixing system comprising:
-
a bone fixing component comprising; a form formed in a shaft shape; and a cut out section area provided with at least one cut out section formed along a direction which crosses with a longitudinal direction of the bone fixing component and cut out from an outer surface toward an inner side, wherein the bone fixing component is insertable into an inner side of each of a first bone piece portion and a second bone piece portion so that the cut out section area is inserted first so that it extends deeper into the bone than the remainder of the bone fixing component; and an intramedullary nail main body formed in a shaft shape and having an intramedullary nail main body longitudinal direction, wherein the intramedullary nail main body includes a proximal end section and a distal end section, an insertion hole formed to extend across the proximal end section in an insertion direction, the insertion hole shaped to receive the bone fixing component, wherein a cross section of the proximal end section taken orthogonal to the intramedullary nail main body longitudinal direction is substantially elliptical, the cross section having a first width extending across the proximal end section and orthogonal to the insertion direction and a second width extending across the proximal end section and aligned with the insertion direction, wherein the first width is greater than the second width. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
