A metatarsus adductus technique may involve cutting an end of one or both of a second metatarsal and an intermediate cuneiform to create a wedge-shaped opening between the end of the second metatarsal and the intermediate cuneiform. The method may further involve cutting an end of one or both of a third metatarsal and a lateral cuneiform to also create a wedge-shaped opening between the end of the third metatarsal and the lateral cuneiform. The second metatarsal and the third metatarsal can then be moved in a transverse plane to close a metatarsus adductus angle. Movement of the second and third metatarsal may close the wedge-shaped openings forming during bone cutting. With the second and third metatarsals appropriately realigned, the clinician can fixate the moved position of the second metatarsal and the third metatarsal.

An electronically assisted artificial vertebral disc having an upper disc plate and a lower disc plate is disclosed. An actuator imparts movement to at least one of the upper and lower disc plates. A control device controls the actuator and the amount of movement between the disc plates. The actuator includes a plurality of either linear actuators or rotary actuators that are driven by electric motors in response to the control device. The control device includes at least a first sensor for detecting the position of the actuator and at least a second sensor for detecting the spatial orientation of at least one of the upper and lower disc plates. The control device also preferably includes a microprocessor that calculates the desired positions of the upper and lower disc plates and provides a control signal to the actuator to drive the upper and lower disc plates to their desired positions.

An off-the-shelf oral splint that is operatively secured to the maxilla and mandible to assist in reduction and provide maintenance of reduction of maxillary and mandibular fractures in the edentulous or partially edentulous patient. The oral splint is fabricated into a plurality of standardized sizes. These sizes are determined by imaging a population of jaws, measuring dimensions thereof, manipulating (e.g., calculating the mean) these dimensions, and generating a size that is representative of a subset of that population. This can be done for all sizes that would represent individuals in that population. The splint itself is fabricated virtually by creating “U-shapes”, splitting them horizontally into halves, creating an evacuation channel, and generating a coupling mechanism to hold the halves together. The splint can then be printed or otherwise manufactured.

The present disclosure is directed to implantable distraction osteogenesis devices and methods of their use. In a non-limiting embodiment, the device has a guide, a first bone attachment device slidably engaged with the guide, a force delivery mechanism coupled to the first bone attachment device and operably engaged with the guide, a regulator operably engaged with the force delivery mechanism, and a second bone attachment device rigidly fixed to the guide, wherein the force delivery mechanism is configured to exert a force to move the first bone attachment device along the guide at a predetermined rate, and the regulator is configured to control the movement of the first bone attachment device along the guide without percutaneous intervention.

A locking fixation device for treating extra-articular fractures includes a connector assembly connected to two end plates. Rotation of the connector assembly about an axis extending therethrough converts rotational motion to linear motion, and advances the end plates in a linear direction away from (lengthening) or toward (compression) each other.

A device for cranial restructuring, by the expansion, compression, or flexure of a cranial structure located between first and second anchor points, includes: a force generator configured to generate force; a first anchor attachment to the first anchor point; a second anchor attachment to a second anchor point; a hydraulic force transmitting structure, connected to the force generator, to transmit the generated force to the anchors thereby putting the cranial structure in tension, compression or flexure. Another device for cranial restructuring includes: a head support, having a head-receiving portion; a force generator to generate force which is periodic; a first anchor attachment to the first anchor point; a force transmitting structure, connected to the force generator, which transmits the periodic force to the anchor in a restructuring direction; wherein the head support includes: a restriction to prevent or restrict movement of the user's head when the periodic force is applied.
