The first bridge member (210) has an interior with a base (240) for receiving the second bridge member (310) with an area having upward projecting teeth (220) and a distal access area (250a) between said area with upward projecting teeth (220) and a distal end (205a) of first bridge member (210). Base (240) also comprises a proximal access area (250b) between said area with upward projecting teeth (220) and a proximal end (205b) of first bridge member (210). First bridge member (210) has a pushing part (255) projecting towards the base (240) for pushing the second bridge member (310) towards the base (240) when inserted in first bridge member (210).

The present disclosure relates to an apparatus for treating a fracture, comprising a nail which can be introduced into an intramedullary canal of a bone, wherein the nail comprises a bore that is aligned roughly transversely to a longitudinal axis of the nail, wherein a coupling device, is provided which can be introduced into the bore such that the coupling device protrudes past the bore on both sides and can be moved within the bore along a transverse axis in a lateral direction and a medial direction oriented in an opposing manner to the lateral direction, and which coupling device can be fixed in place at an end in a bone part, wherein an adjusting device is provided which can be fixed in place in different positions relative to the nail and wherein the adjusting device comprises a first stop surface that limits a mobility of the coupling device in a lateral direction when the coupling device and adjusting device are arranged on the nail, so that by changing the position of the adjusting device relative to the nail, a lateral end position up to which the coupling device can be moved relative to the nail in a lateral direction can be altered.

The invention relates to an orthosis (1) for wearing on a hand (2) of a person for at least limiting the movement of the carpometacarpal joint (CMCj) of the thumb, preferably also limiting the movement of the metacarpophalangeal joint (MCPj) of the thumb (2-1), the orthosis (1) comprising a metacarpal portion (3) extending across the metacarpal bones of the fingers 2 to 5 and a thumb portion (4) in a curved or ring shape fitting around the thumb (2-1), preferably around the proximal phalanx (6) of the thumb (2-1). The thumb portion (4) is connected to the metacarpal portion (3) via a thumb metacarpal portion (7) extending along and / or around the thumb metacarpal (8) when the orthosis (1) is worn on the hand (2).

A compressor-distractor device may be used during a surgical procedure, such as a surgical procedure to correct a bunion deformity. In some examples, the compressor-distractor includes first and second engagement arms having first and second pin-receiving holes, respectively. The first and second pin-receiving holes may be angled relative to each other. The compressor-distractor may also include an actuator operatively coupled to the first and second engagement arms. In some example uses, a clinician may pin a first surgical device to a patient's bones use a pair of parallel pins. After removing the surgical device over the parallel pins, the clinician may thread the parallel pins through the angled first and second pin-receiving holes of the compressor-distractor, causing the bones to move relative to each other. Thereafter, the clinician may actuate the actuator on the compressor-distractor to move the bones towards and / or away from each other.

A device for treating a bone fracture, in particular a femur fracture such as a femoral neck break, includes a holding part fastenable in or on a first bone part, wherein the holding part has at least one opening through which a bone screw and an adjusting screw are guided. The opening includes on the inner side a surface having a threaded surface that the adjusting screw engages, with the bone screw being able to slide freely in the opening, and the adjusting screw is configured to allow the bone screw to rest against at least one stop of the adjusting screw, if necessary after a lateral sliding of the bone screw. An adapter that can be fixed in the bone screw to be laterally releasable forms a barrier for the adjusting screw in the event of lateral movement of the adjusting screw.

A method for at least partially severing a neck bone portion having a spinal column, featherbones and a rib structure from a partial carcass is provided. The method comprises cutting the carcass with a first cutting tool adapted to cut the partial carcass along a first cutting path around and along the spinal column to a predetermined cutting length, according to a first cutting sequence and cutting the carcass with a second cutting tool adapted to cut the partial carcass along a second cutting path around the rib structure and around the spinal column, according to a second cutting sequence. The first and second cutting sequences are performed in a single continuous or semi-continuous operation. There is also provided a cutting assembly and a meat processing system.
