A radiolucent, 3-D printed soft tissue retractor includes an elongate, curved support body having a long central axis that exceeds the length of a short, transverse axis. A bone engaging concavity is provided on a first side of the body. A concave soft tissue retracting surface is provided on a second side of the body. An inflection point is provided on the body in between the bone engaging concavity and the soft tissue retracting surface. The soft tissue retractor is configured to cooperate with a second soft tissue retractor and a backing plate to retract tissue and stabilize bones during a surgical distal radius fracture repair.

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.

A device for registering a bone for a robotic shoulder arthroplasty with a surgical robot. The device can include a first portion engageable with a first portion of a bone and can include a second portion engageable with a second portion of the bone, the second portion connected to the first portion and rotatable with respect to the first portion. The device can include a registration device connectable to the first portion and configured to interface with the surgical robot for registration of the device and the bone. The device can include an actuator engageable with the first portion and the second portion to move the second portion toward a closed position away from an open position.

A method of preparing a tarsometatarsal joint can include imaging a tarsometatarsal joint of a patient between a metatarsal and a cuneiform to determine a size and/or angle of a wedge-shaped bone portion to be cut at the tarsometatarsal joint. The method can include obtaining a bone preparation guide that includes a first guide surface positionable over the metatarsal and a second guide surface positionable over the cuneiform, where an angle of the first guide surface relative to the second guide surface is selected corresponding to the size and/or angle of the wedge-shaped bone portion to be cut as determined via imaging of the tarsometatarsal joint. The method can include positioning the guide surfaces over the metatarsal and cuneiform and guiding a tissue removing instrument with the guide surfaces to cut an end of the metatarsal and to cut an end of the cuneiform.

A multifunctional traction and bone fixation device relates to the technical field of medical devices. Two traction clamping plates serve as a base. The front of each of the two traction clamping plates defines a traction nail. The middle portion of the clamping plate is arranged with a positioning and pressurizing screw. The rear end of the clamp plate is arranged with a traction handle screw. The clamping plate is arranged with a plurality of auxiliary fixation pin holders and auxiliary fixation pins. Heads of two traction nails are injected in opposite directions into a lower portion of a fracture site to determine a fixation position. Rear ends of the two traction clamping plates extend along the thigh direction to be weighted-pulled.

A coracoid guiding system. The coracoid guiding system includes a coracoid grasper for holding an exteriorized coracoid bone block, and a coracoid passer. The coracoid passer has a pair of external barrels, a pair of internal barrel pins, a hollow guiding tube including an inner surface and an outer surface, and a hook gauge. The hook gauge is configured to be retractably arranged inside the hollow guiding tube. The hook gauge has a proximal end, a distal end, a curved section between the proximal end and the distal end, a first straight section extending from the proximal end to the curved section, a second straight section extending from the curved section to the distal end, wherein the distal end of the hook gauge is shaped as a hook.

A system for providing fixation of first and second bones includes a drill guide that receives a drill bit to create first and second holes in the first and second bones, respectively. Guide pins can be driven into the first and second holes. The guide pins are received by a surgical saw to guide the surgical saw toward a joint between the first and second bones, thereby creating a third hole in each of the bones across the joint. The guide pins are then removed, and an implant can be inserted into the bones, such that a first leg of the implant is disposed in the first hole, a second leg of the implant is disposed in the second hole, and a keel of the implant is disposed in the third hole.

Apparatus and methods are disclosed for correcting deformities in a patient's foot. In one example, a metatarsus adductus is addressed using a pin placement guide that is angulated to be placed in alignment with a cuneiform and a metatarsal, such that the TMT joint can be subsequently cut, and the metatarsal moved into proper alignment. Th pin placement guide can be a variable angle guide, or a kit of fixed-angle pin placement guides can be provided.

A surgical elevator device that can be used in the reduction of bone fractures, particularly facial bone fractures, and even more particularly zygomatic arch fractures. The elevator device enables accurate measurement of the depth of insertion of the device into tissue space and provides tactile control of fracture location and reduction. In one embodiment, the elevator device comprises a groove on an elevator element for receiving a bone structure. The groove can be formed by a pair of parallel ridges. A projection extending from the elevator provides a pivot point for applying a controlled force to the bone to reduce the fracture. A preferred embodiment further comprises a method of reducing a bone fracture, such as a zygomatic arch fracture.

A humeral head implant system includes a head component including a first articulating surface, a second bottom surface extending from the first spherical articulating surface, a first cavity extending a first distance into the head component from the second bottom surface, and a second cavity extending into the head component along a cavity axis. The head component defines a head axis extending through a center of the first articulating surface parallel to the cavity axis. A base component defines a slot extending from a first width to a second width. An insert component includes an insert body, a first engagement feature, and a slot engagement feature. The first engagement feature is received in the second cavity along the cavity axis. The insert body has an insert thickness less than the first distance, and the slot engagement feature slides into the slot in a direction transverse to the cavity axis.
