  • Patent number: 11602382
    Abstract: A device for fixation of inner and outer bone fragments comprises at least three fixation means (5), at least one tilting preventing means (6) and a securing plate (7). The fixation means (5) are configured to allow, during secondary compression of the inner and outer bone fragments (2, 3), a sliding movement of the fixation means and said outer bone fragment relative to one another and thereby an interruption of an engagement of the securing plate (7) with the outer bone fragment (3) without affecting the angular position of the fixation means relative to the securing plate and relative to one another. The tilting preventing means (6) is configured to allow, during said secondary compression, a sliding movement of the at least one tilting preventing means and said outer bone fragment (3) relative to one another and thereby an interruption of the engagement of the securing plate (7) with the outer bone fragment.

  • Patent number: 11529178
    Abstract: A targeting device (100) for use in fixation of bone fragments at a bone fracture. The targeting device comprises an elongated body portion (110) comprising a first body end (111), an opposed second body end (112), and body through holes (113a, 113b, 113c) extending from the first body end to the second body end for guiding a respective fixation means (303; 303a, 303b, 303c) through the body portion. In its second body end the body portion is configured with a snap-fitting means (114) configured to removably attach a fixation plate (150) to the body portion such that fixation through holes (151) of the plate are located in line with a respective body through hole and, when in use, to provide a surface of the plate to abut a surface of an outer bone fragment for subsequent fixation of the plate to the fragment. The targeting device comprises further a bracket (120).

  • Patent number: 10758281
    Abstract: The present invention relates to a method for fixing an intramedullary cavity nail for the treatment of unstable trochanteric fractures and to a targeting device for use in performing the steps of said method. According to the method, a recess (16) for a femur neck screw (8) for fixing the cavity nail (2) is provided in at least the lateral cortex of the femoral shaft (FS) in close distal proximity to a hole (9) for the femur neck screw such that bone fragment(s) located distally of the fracture and bone fragment(s) located proximally of the fracture relatively seen can be displaced towards each other. A targeting head (5) of the targeting device (1) is configured with a targeting bore (14) which is alignable with a point on the femoral shaft (FS) in close distal proximity to the hole (9) for the femur neck screw (8) for use in providing at said point, said recess (16) for the femur neck screw.

  • Patent number: 10463262
    Abstract: An instrument (1) for use in measuring blood flow in the femoral head after a femoral neck fracture comprises a sleeve (2) and a rod (3) which is displaceably mounted in the sleeve. The sleeve (2) is configured for insertion into a bore (4) in the femoral neck (5) and femoral head (6) and provided with at least one aperture (8) at a front portion (2a) thereof. The aperture (8) in the front portion (2a) of the sleeve (2) is intended for location in the femoral head (6) distally of the fracture (7) after the sleeve has been inserted into said bore (4). The rod (3) is configured for closing the aperture (8) in the sleeve (2) during insertion of the sleeve into the bore (4) in the femoral neck (5) and femoral head (6) and for exposing said aperture after said insertion. Thereby, blood leaking into the bore (4) at the front portion (2a) of the sleeve (2) can be collected by the sleeve through the aperture (8) therein for subsequent measuring of the volume of the collected blood.

  • Patent number: 9642657
    Abstract: The present invention relates to a device for fixation of bone fragments at bone fractures. The device comprises at least two fixation means (1) and a securing plate (17). The securing plate (17) has threaded holes (19). The fixation means consist of bone nails (1) which each comprises a sleeve (5) with a displaceable pin (7) inside the sleeve. A forward portion (9) of the (7) pin defines a first fixing portion for fixing the bone nail (1) in an inner bone fragment (3). A threaded rear end portion (18) of the sleeve (5) defines a second fixing portion for locking the bone nail (1) to the securing plate (17). The sleeve (5) has a middle portion (32) along which the outer bone fragment (2) can slide inwards towards the inner bone fragment (3).
