Abstract: The invention relates to a new type of axial unilateral external splint device for stabilizing bone fractures, comprising an extendible rod-like middle body (2) and oppositely located bone screw clamps (5, 6) which are articulated to respective ends (3, 4) of the rod-like middle body (2) by means of ball joints. Advantageously, a ball-and-socket joint (16) is mounted to each clamp (5, 6), within a main body (20) with which a bone screw clamping arrangement (25, 26, 21, 22, 23) is associated or co-operates. Also provided are ancillary members (30) adapted for removable association with the end of each clamp (5, 6) to allow each clamp to be more suitable for use, depending on the different operative installation conditions of the fixator.

Abstract: The invention relates to a novel type of an external fixation device having a carrying structure (1; 40) of interconnected elements (2, 5, 6) comprising an extendible central body (2), and clamps (5, 6) for bone screws respectively articulated on opposed ends (3, 4) of the central body (2), said central body comprising two parts (8, 9) telescoping slidable one on the other, each of said parts (8, 9) including a first portion (8a; 9a) of elongate shape formed integrally with a second end portion (8b; 9b) of substantially cylindrical shape, said first portions (8a, 9a) of the parts (8, 9) being slidably coupled to each other by means of a driving groove (7) formed longitudinally in one the first portion (8a) and a corresponding slide (7a) formed longitudinally in the other first portion (9a) and means being provided in said parts (8, 9) for stopping their sliding movement characterized in that it further comprises at least one plate (27; 41; 42; 43; 60) having predetermined contour shape and thickness, at least

Abstract: The invention relates to an external fixator apparatus (1) of the ring type for stabilizing bone fractures, comprising at least one pair of rings (6, 7), of which one (6) is proximal and the other (7) is distal, and at least one tie rod (8, 9, 10) interconnecting the rings (6, 7) to each other, wherein the rod (8, 9, 10) is split into two rod sections (11, 12) connected together by a joint (21) and the joint (21) comprises a pivot mount (22) having a predetermined axis (x-x) for the angular displacement of the rod sections (11, 12), and comprises a sliding mount (23) according to a predetermined sliding direction (y-y) for offsetting the rod sections (11, 12).

Abstract: The invention relates to a clamp element for external fixator apparatuses of the rod and ring type used for stabilizing bone fractures in orthopedic surgery; a clamp connector secures at least one of the bone fragment stretching wires and the bone screws to the rings. The invention comprises a swivel joint comprising a first part and a second part associated with each other around a common pivot axis, each part being formed with at least one hole of a predetermined diameter for clamping the stretching wire or the bone screw therein. Also provided on each of the parts are clamping mechanisms for attaching to a rod or to a ring of the fixator device. The clamping mechanisms are used for clamping the stretching wire or the bone screw in the part of the swivel joint which is not connected to the rod or to the ring.

Abstract: The invention relates to a clamp element for external fixator apparatuses (2) of the rod (8,9,10) and ring (6,7) type used for stabilizing bone fractures in orthopedic surgery; such clamp connector secures at least one of the bone fragment (3) stretching wires (4) and the bone screws (11) to one of the rings. Advantageously, the element of this invention comprises a swivel joint (12) consisting of a first part (13) and a second part (14) associated with each other around a common pivot axis (x-x), each part (13,14) being formed with at least one hole (16) of a predetermined diameter for clamping the stretching wire (4) or the bone screw (11) therein. Also provided on each of the parts (13,14) are the means (18) of clamping to a rod (8,9,10) or to a ring (6,7) of the fixator device, and these clamping means are used for clamping the stretching wire (4) or the bone screw (11) in the part (13,14) of the swivel joint (12) which is not connected to the rod or to the ring.
