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 four corner fusion system can include a curved plate that is more aligned with the natural anatomy of the wrist joint, and/or fewer number of screws (for example, about three or four screws). The system can have a lower profile, resulting in less soft tissue impingement. A surgical tool with a pair of offsetting clamping arms can be used to aid in bone reduction during a wrist fusion procedure.

Various embodiments of an anchor and intradiscal implant for surgical realignment of a misaligned spine are disclosed herein.

A medical robot system, including a robot coupled to an effectuator element with the robot configured for controlled movement and positioning. The system may include a transmitter configured to emit signals, and the transmitter is coupled to an instrument coupled to the effectuator element. The system may further include a motor assembly coupled to the robot and a plurality of receivers configured to receive the signals emitted by the transmitter. A control unit is coupled to the motor assembly and the plurality of receivers, and the control unit is configured to supply instruction signals to the motor assembly. The instruction signals can be configured to cause the motor assembly to selectively move the effectuator element and is further configured to (i) calculate a position of the transmitter; (ii) display the position of the at least one transmitter; and (iii) selectively control actuation of the motor assembly.

In one aspect of the present disclosure, a sterilization mat is provided that is configured to receive non-sterile surgical instruments, rolled to a rolled configuration, and sterilized while in the rolled configuration. In accordance with another aspect of the present disclosure, a specialized surgical supply kit includes a package that retains surgical supplies having at least one surgical supply identified as a preferred surgical supply by the hospital or surgeon that is to perform the surgery. The surgical supplies are further arranged in a spatial arrangement based on the surgeon who is to perform the surgery.

A removable wedge for high tibial osteotomy surgery, comprising: a truncated wedge configured to provide a patient specific correction to the weight bearing axis based on 3D data for that patient’s tibia, femur and/or fibula; and an anterior flange configured to locate the partial wedge in a predetermined location on the tibia of that patient. Also a method for pre-operative planning, a method of designing a wedge, a method of printing a wedge a reusable wedge and a prosthetic implant.

Plate holding forceps for one-hand use are presented. The forceps are configured to press a bone plate to bone and comprise a clamp portion, including a first jaw and second jaw movable towards and away from each other. At least the first jaw includes a through-bore configured to be aligned with a hole of a bone plate engaged by the plate holding forceps. The forceps also include an adjustment portion configured to adjust a distance between the jaws. The adjustment portion includes a first handle part and a second handle part manually movable with the fingers of one hand relative to each other and configured to thereby adjust the distance between the jaws.

A device includes a plurality of rings. Each ring has a first face, a second face, and at least one slot defined by first and second interior edges of the ring on opposing sides of the slot. The at least one slot penetrates from the first face to the second face. The first face of each ring has a first recess adjacent the slot on the first edge and a second recess adjacent the slot on the second edge. A plurality of posts join each one of the plurality of rings to an adjacent one of the plurality of rings.

A bone displacement system includes an anchoring portion, a flexing mechanism, and a distal body. The anchoring portion has an aperture for receiving a wire to connect the anchoring portion to a proximal bone. The flexing mechanism is connected to the anchoring portion, and has a rail and a holding portion movable on the rail. The rail is curved about a center of rotation located toward a bottom of the flexing mechanism and toward the proximal bone. The distal body is connected to the holding portion. The distal body has an aperture for receiving a wire to connect the distal body to a distal bone. The flexing mechanism is configured to move the distal body relative to the anchoring portion by a movement of the holding portion on the rail and about the center of rotation to flex the first bone relative to the second bone.

A surgical derotator instrument comprises a shaft, a handle and an articulating coupler. The shaft comprises a first end portion having a bone anchor coupling and a second end portion opposite the first end portion. The handle comprises a body portion and a slot extending in the body portion. The articulating coupler connects the shaft and the handle. A method for coupling a plurality of derotator instruments into a series of derotator instruments comprises: attaching a plurality of derotator instruments to a plurality of adjacent bone anchor housings, each derotator instrument comprising: a shaft for connecting to a bone anchor housing, a handle having a slot, and an adjustable coupler connecting the shaft and the handle; adjusting one or more of the adjustable couplers to align at least one of the slots of the series with other slots of the series; and inserting an elongate member through the at least one slots that are aligned.
