In an example, a clamping assembly includes a longitudinal member having a first end and a second end, the second end defining a first clamp, a second clamp configured to attach to the first end of the longitudinal member and connect to a rod assembly, a clamping member including a first end, a second end defining a spherical portion, and a third clamp, where the first clamp of the longitudinal member is configured to receive the second end of the clamping member.

External fixation systems, and methods for immobilizing joints or fractured bones. An external fixation system may include one or more clamp assemblies connected to one or more rod assemblies at polyaxial joints. Each rod assembly may be length adjustable, and may include a one-way locking mechanism to provisionally lock the length of the rod assembly, and additional locking mechanisms to permanently lock the length of the rod assembly. The system may be deployed pre-assembled as a unit to immobilize a joint or fracture. Another external fixation system further includes a spanning member extending transverse to the rod assemblies. Two or more external fixation systems may be deployed in a stacked configuration on one set of bone pins to immobilize two joints and/or fractures. The systems may be provided in kits including guiding instrumentation, bone pins and pin clamping assemblies for connecting the bone pins to the external fixation systems.

The present invention is a hole extender, in which a hole transporter includes a transport beam having a first flange with a first flange pin and a first flange hole, and at the other end of the transport beam is a second flange with a second flange hole. Key features of the present hole transporter include that the main direction of each flange is perpendicular to the beam, and the direction of the second flange hole is parallel to the direction of the first flange hole.

System for connecting a connection device to a bone with a bone pin, wherein the system comprises a connection device provided with an opening for receiving the bone pin, and wherein the system further comprises a locking device arranged to be received in the opening of the connection device and which is arranged to engage the bone pin for locking the bone pin with respect to the connection device, wherein the locking device is movable between a locked position, wherein the bone pin is locked with respect to the connection device, and an unlocked position wherein the bone pin is movable with respect the connection device, wherein the system further comprises a blocking mechanism for at least partially blocking the opening in the connection device upon removal of the bone pin from the opening.

An external fixation system may have a first bone anchoring body configured to be secured to a first bone, a second bone anchoring body configured to be secured to a second bone, and a first strut assembly. The first strut assembly may have a first end configured to be removably coupled to the first bone anchoring body, a second end configured to be removably coupled to the second bone anchoring body, an intermediate portion that extends between the first end and the second end, the intermediate portion having a length that is adjustable, and a clutch mechanism. The clutch mechanism may be movable between an unlocked position in which the clutch mechanism allows both increase and reduction in the length, and a restricted position in which the clutch mechanism allows one of increase and reduction in the length while restricting the other of increase and reduction in the length.

The skull clamp system with pressure limiting and alarm systems includes at least one and preferably multiple inwardly power driven immobilizing pins adjustably engaging the skull of a patient. The pin power drive systems includes at least one sensor capable of sensing the degree of back pressure on the pin from contact of the pin against the bone of the patient, the sensor being capable of signaling the drive system to stop when the sensor detects a preselected degree of back pressure. The sensor is also capable of signaling an alarm to warn of any reduction of pressure applied to the pins that might result from pin slippage.

The present invention relates to an external fixation system including at least one pair of connected clamp units forming at least one clamp. Each of the clamp units includes: a first component comprising a molded metal, the first component having a first exterior surface having a plurality of voids formed therein to define a plurality of interconnected ribs and a first periphery having at least one first pin groove formed therein; and a second component mated to the first component and including a second periphery having at least one second pin groove formed therein, the at least one first pin groove and at least one second pin groove together forming a fixation pin holder. A fixation pin is held in at least one of the fixation pin holders.

The present application provides external bone and tissue fixation systems and related methods. The fixation systems may include an elongate beam element defining an axis with an axially extending threaded track portion. The systems may also include at least one drivable fixation clamp assembly comprising a housing with a central bore, a driving housing rotatably coupled to the housing, a threaded driving member, and a clamp assembly rotatably coupled to the housing configured to clamp to at least one fixation member. The elongate beam element may extend axially through central bore of the housing. The driving member may be movable with respect to the central bore via rotation of the driving housing between engaged and disengaged states with the threaded track portion. Rotation of the driving member in the engaged state may axially translate the clamp assembly along the beam element.
