A clamping device for an external fixation system includes a clamp body including, a first jaw and a second jaw, wherein the first jaw and the second jaw form a groove configured to receive an external fixation component and a bore configured to receive a bone pin. The clamping device includes a locking assembly coupled to the clamp body and configured to change state between at least an unlocked state and a locked state, wherein the external fixation component is configured to translate within the groove and the bone pin is configured to translate within the bore when the locking assembly is in the unlocked state, and the first jaw and the second jaw restrict movement of the external fixation component within the groove and the bore restricts the bone pin from translating within the bore when the locking assembly is in the locked state.

Length-adjustable strut assemblies for external fixation systems, and corresponding external fixation systems, are disclosed. The strut assemblies include an elongate first and second end members, an elongate intermediate member, and first and second adjustment mechanisms. The intermediate member comprises a threaded rod fixedly coupled within an axial cavity thereof, and is rotatably fixed and axially translatably within an axial cavity of the first end member. An end portion of the second end member is received within the axial cavity of the intermediate member, and the second end member comprises an axial cavity threadably coupled with the threaded rod. The first adjustment mechanism is configured to selectively axially fix the intermediate member relative to the first end member. The second adjustment mechanism is configured to selectively rotate the second end member with respect to the threaded rod to axially translate the second end member relative to the intermediate member.

An external fixation strut and corresponding systems and methods of use with a bone alignment device are disclosed. The external fixation strut may provide an enhanced range of adjustable lengths and may be connected to a bone alignment device, thereby enabling the bone alignment device to be used over a larger workable range. As a result, comfort of a patient may be improved as the need to switch out the external fixation strut may be prevented. The external fixation strut may also include a single measurement scale that may be easily viewed and used to adjust the length of the external fixation strut, thereby ensuring more accurate length adjustments.

An improved orthopaedic external fixation system with removable rails or skates and may include: at least a distal foot fixation element; at least a pair of rails or skates removably connected to the foot fixation element; at least a load sensor associated to at least one of the rails or skates; an electronic apparatus coupled to the load sensor and receiving an electric signal from the load sensor; an electronic controller coupled to the apparatus and issuing at least a flag signal upon detection of a threshold pressure force on said at least one of said rails or skates. This electronic controller may be mounted on the orthopaedic system or may be a structurally independent host device including a controller that is in signal communication with the load sensors.

An external fixation system may include first and second fixation rings and a plurality of adjustable length struts. Each adjustable length strut may have two joints, a rod, a tube, and an actuator configured to drive the rod axially relative to the tube to change an effective length of the strut. The system may include a plurality of controller modules each configured to couple to a corresponding strut. The external fixation system may have a manual mode of operation in which the controller modules are not coupled to the struts, and manual actuation the actuators changes the effective lengths of the struts in discrete length increments. The external fixation may have an automated mode of operation in which the controller modules are coupled to the struts, and automated actuation of the actuators changes the effective lengths of the struts in infinitesimally small length increments.

An external fixator (1) for bone fractures is proposed herein, comprising at least two support units (2, 2′) for removably supporting bone screws (3). Each support unit (2; 2) comprises: a pair of support bodies (201), which are curved; a single support pin (202) or a pair of support pins (202) fixed to only one or both support bodies (201); a pair of locking devices (5) of a bone screw (3), fixed both to the single support pin (202) or, each to a respective support pin (202). Each locking device (5) comprises a locking element (501) of the bone screw (3); a locking pin (502) configured to support the locking element (501); wherein the locking element (501) is configured to rotate around the locking pin (502) and the locking device (5) is configured to rotate around the support pin (202) and to slide along the support pin (202) in such a way as to allow a versatile positioning of each bone screw (3), in a bone screw (3) positioning step.

A locking device (5) of a bone screw (3) for an external fixator (1) for bone fractures is described herein, wherein the external fixator (1) comprises at least one support pin (202). The locking device (5) comprises a locking element (501) of the bone screw (3); a locking pin (502), which is configured to support the locking element (501), the locking element (501) being configured to rotate around the blocking pin in a bone screw positioning step; a coupling element (503), which is provided with a respective coupling seat (503b) configured to receive the support pin (202) by snap-fit coupling and to allow, during the bone screw (3) positioning step, a rotation of the locking device (5) around the support pin (202) and a sliding of the locking device (5) along the support pin.

A fixing clamp for an aligning device, and an aligning device that includes the fixing clamp, for clamping to a bodily extremity. The clamp includes a first clamp arm, a second clamp arm and a frame device having an attaching section for attaching to an adjustment rod. The first clamp arm is rotatably attached to a first rotary joint about a first axis of rotation, and the second clamp arm is rotatably connected to a second rotary joint about a second axis of rotation. A locking mechanism locks the first clamp arm and/or the second clamp arm relative to the frame device in at least one position, and blocks movement of the first or second clamp arm about the respective rotary joint in an open rotational direction.

A coupling device includes a first coupling body configured to be coupled to a first bone anchor, a second coupling body configured to be coupled a second bone anchor, and a connection device comprising a first connection member connectable to the first coupling body, a second connection member connectable to the second coupling body, and a length adjustment member positionable between and insertable at least partially into each of the first and second connection members. The first and second connection members are movable relative to the length adjustment member. The length adjustment member can be actuated in a first direction to increase a distance between the first connection member and the second connection member, and in a second direction different from the first direction to decrease the distance between the first connection member and the second connection member.

Disclosed are improved devices, systems and methods for external fixation and/or support of damaged or fractured limbs or other anatomies of a patient.
