Patent ID: 8852246

Claim:
A device for internal fixation of bone fragments ( 2 , 3 ) in a radius fracture ( 4 ), which device comprises at least one body ( 1 ) for abutment against the bone fragments ( 2 , 3 ) in the radius fracture ( 4 ), and a plurality of fixing elements including at least two distal and at least two proximal fixing elements ( 6 , 7 ) which are intended to be locked to the body for fixation of said bone fragments, which body ( 1 ) has a plurality of predrilled holes, the body having, in a distal end portion ( 1 a ) at least two predrilled holes ( 8 ) for the distal fixing elements ( 6 ), and in a proximal end portion ( 1 b ) at least two predrilled holes ( 9 ) for the proximal fixing elements ( 7 ), the distal end portion and the proximal end portion of the body engaging the bone fragments on opposite sides of the radius fracture when the body abuts against the bone fragments, wherein all of the predrilled holes ( 8 , 9 ) run obliquely relative to a longitudinal axis (L) of the body ( 1 ) so that all of the fixing elements ( 6 , 7 ) which, after abutment of the body against the bone fragments ( 2 , 3 ) in the radius fracture ( 5 ), are introduced into said bone fragments through holes ( 8 , 9 ) in the body's distal end portion ( 1 a ) and proximal end portion ( 1 b ) cross the radius fracture as viewed in the transverse direction of the body when the body abuts against the bone fragments, and each fixing element ( 6 , 7 ) has at least one fixing portion ( 10 ; 10 a , 10 b ) for locking the fixing element in the bone fragments ( 2 , 3 ) in the radius fracture ( 4 ) and for locking the fixing element to the body ( 1 ); and all of the predrilled holes ( 9 ) in the proximal end portion ( 1 b ) of the body ( 1 ) run obliquely relative to the body's longitudinal axis (L) so that all of the proximal fixing elements ( 7 ) introduced through them are situated, as viewed in the body's longitudinal direction, in a common plane which is oriented in the body's longitudinal direction, and all of the predrilled holes ( 8 ) in the distal end portion ( 1 a ) of the body ( 1 ) run obliquely relative to the body's longitudinal axis (L) so that each of the distal fixing elements ( 6 ) introduced through them are situated in different planes as viewed in the body's longitudinal direction, and the planes in which the distal fixing elements ( 6 ) are situated run at angles relative to the plane in which the proximal fixing elements ( 7 ) are situated and relative to one another as viewed in the longitudinal direction of the body ( 1 ), wherein all of the predrilled holes ( 8 , 9 ) run obliquely relative to the longitudinal axis (L) of the body ( 1 ) so that the distal fixing elements ( 6 ) introduced through the predrilled holes ( 8 ) in the body's distal end portion ( 1 a ) cross, as viewed in the transverse direction of the body, the proximal fixing elements ( 7 ) introduced through the predrilled holes ( 9 ) in the body's proximal end portion ( 1 b ).
