Abstract: The present invention relates to an intramedullary nail for proximal femoral fractures. The intramedullary nail comprises an elongate body (1) with a longitudinal bore (2). The elongate body (1) includes a proximal portion (5) with an oblique transverse bore (7) for a proximal locking member and a distal portion (6) with at least one transverse bore (8) for a distal locking member. An inlet end of the oblique transverse bore (7) is configured as a recess (9) with a recessed surface (11). The recessed surface (11) is composed of recessed lateral surface portions (15) and a recessed proximal as well as a recessed distal surface portion (16 and 17 respectively). Each of the recessed lateral surface portions (15) is configured with at least one protuberance (18) for preventing or reducing the risk for misalignment of e.g. a reamer and, if misalignment occurs, this will not affect critical parts of the intramedullary nail.

Abstract: The present invention relates to an osseous pin (1) for bone fracture fixation. The pin comprises a threaded front section (2) and an unthreaded rear section (3). The threaded front section is configured with two or more kerfs (4) to facilitate breaking of the pin at any one of said kerfs. The present invention also relates to a guide sleeve for use in insertion of the osseous pin (1) into bone fragments at a bone fracture and breaking of said pin at the kerf (4) closest to the entrance site of the pin into the bone fragments. The present invention also relates to an extraction member for use in extraction of the osseous pin (1) from bone fragments at a healed bone fracture and a kit, comprising said components.

Abstract: A flexible surgical screw driver comprises a rotatable handle member, a shaft member and a flexible member. The handle member is configured with a first coupling means and the shaft member with a second coupling means. These first and second coupling means are configured to cooperate such that the handle member and the shaft member are angularly displaceable relative to each other and such that said handle member and said shaft member are non-rotatably coupled to each other for driving a screw with rotation transmitted from the handle member. The flexible member is configured to connect the handle member and the shaft member to each other and hold said handle member and said shaft member together such that the longitudinal axes thereof are substantially aligned and such that angular displacement of the handle member and the shaft member relative to each other such that the longitudinal axes thereof are misaligned, can be performed against the action of said flexible member.

Abstract: A device for fixation of bone fragments (4, 8) comprises a locking plate (1) for fixation on the outside of an outer bone fragment (4). The locking plate has a distal portion (1 a) with at least one first hole (6), extending through the locking plate, for a distal fixing means (2) and a proximal portion (1 b) with a second hole (7), extending through the locking plate, for a proximal fixing means (3). The locking plate (1) is configured also with a third hole (9) which is located between said at least one first hole (6) in the distal portion (1 a) of the locking plate and said second hole (7) in the proximal portion (1 b) of the locking plate and this third hole extends as the other holes through the locking plate. The device further comprises a rotary-preventing and load-carrying means (10) which is configured for inser¬tion and fixation in said third hole (9) in the locking plate (1) and by cooperating with the proximal fixing means (3) prevent rotation of the proximal fixing means but permit displa¬cement thereof in its longitudinal direction relative to the rotary-preventing and load-car¬rying means during compression after surgery of the outer and inner bone fragments (4, 8) and facilitate for the proximal fixing means to carry loading forces acting on the inner bone fragment (8).

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). The thread of each threaded hole (19) in the securing plate (17) is configured such that after screwing of the threaded rear end portion (18) of the sleeve (5) into the threaded hole until it reaches a surface in the hole against which said threaded rear end portion can abut, a side aperture for the pin (7) in the sleeve is oriented in a predetermined direction in the inner bone fragment (3).

Abstract: A prosthesis for primary artrodhesis can be used for artroplasty and a prosthesis for artroplasty comprises members for artrodhesis. The prosthesis (1b) for primary artrodhesis comprises a locking member (33b) with an attachment portion (16b) which is insertable into a hole (8b) in a first attachment member (4b) of the prosthesis for location of the locking member therein, and a lockable member (34b) integral with a second attachment member (5b) of the prosthesis. The lockable member (34b) is configured for adjustable setting thereof relative to the locking member (33b) and for fixation thereof, in set position, to the locking member. Alternatively, the lockable member comprises an attachment portion which is insertable into a hole in the second attachment member for location of the lockable member therein. At the prosthesis for artroplasty, the hole in the first screw-like attachment member is partly configured to define a press fit with an attachment pin of a socket member and partly threaded to permit, after removal of the socket member, during artrodhesis, securing by screwing in the hole of the locking member for cooperation with a lockable member which is configured for adjustable setting thereof relative to the locking member and for fixation thereof, in set position, to the locking member.

Abstract: A prosthesis for reconstruction of a distal radioulnar joint, after resection of a part of the ulna, includes a first prosthesis member, fixation members and a second prosthesis member. The first prosthesis member is configured for fixation to the distal end portion of the ulna. The fixation members are configured to extend into the radius via said distal end portion of the ulna for locking said distal end portion of the ulna to the radius. The second prosthesis member is configured for fixation to the ulna close to said distal end portion of the ulna. The second prosthesis member is also configured to extend into said space for being joined with the first prosthesis member in a manner which allows said first and second prosthesis members to at least pivot and rotate relative to each other.
