Described is a locking intramedullary nail for insertion in the medullary cavity of hollow bones for treating bone fractures or for joint stiffening. The nail comprises an oblong shaft having at least one holder for a locking screw. In the region of an opening a roller or ball-shaped sleeve having a bore for receiving the locking screw is arranged. The sleeve which is supported in the shaft in a freely pivotable manner can be locked in a positionally stable manner in the shaft. This affords the ability to introduce the locking screws during the implantation of the intramedullary nail at an optimum angle for the respective anatomical or pathological situation of the patient and to subsequently lock it permanently at a constant angle.

A system for penetrating the lateral cortex of a long bone includes a tubular cortex penetrator having an inner surface and an outer surface, a proximal end, and a distal end comprising a beveled cutting edge configured to penetrate the lateral cortex. A guide wire is configured to pass over the tubular cortex penetrator, and a guide sleeve is configured to surround the outer surface of the tubular cortex penetrator. A hollow extraction screw with an axial bore, a proximal end, a distal end, and a threaded cutting edge is configured to pass through the axial bore of the hollow extraction screw; and the hollow extraction screw is configured to retract into a distal end of a bore through the tubular cortex penetrator.

An aspect of the disclosure relates to an intramedullary device configured for ankle fusion. The intramedullary device for ankle fusion includes: a housing configured to be coupled to a calcaneus bone; and a rod configured to be coupled to a tibia bone, wherein a distal end of the housing includes an external thread. The rod is configured for telescopic movement relative to the housing, and to retract relative to the housing to cause ankle fusion. After fusion is achieved, the rod can be distracted to correct a limb length discrepancy.

An intramedullary bone fixation device is provided with an elongate body having a longitudinal axis and an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a fixation device into an intramedullary space of the bone to place at least a portion of the fixation device on one side of the fracture, providing rigidity across the fracture, and operating an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations allow a segmented device body to lock in the intramedullary space before and/or after fixation of the bone.

An improved ultrasound probe (100) has an ultrasound transducer as a body (10) and is capable of accurate positioning on target operative regions of a patient after being improved. The ultrasound probe (100) at least comprises the body (10) and an engagement member (20); the body (10), at an end thereof, comes into contact with patient skin (S), and is provide, on a side surface thereof, with a groove (11) extending from the end that can contact the patient skin (S); the engagement member adjoins the groove (11) of the body (10), allowing one side surface of an article to be disengaged from or engaged in the groove (11), and the engagement member (20) is located at a first location and a second location relative to the groove (11); the article is engaged in the groove (11) when the engagement member (20) is located at the first location relative to the groove (11), and on the contrary, the article is disengaged from the side surface of the body (10) when the engagement member (20) is located at the second location relative to the groove (11).

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

A field generator for use in a surgical targeting system is disclosed. The field generator includes a mounting structure including elements that are configured to receive components of an electromagnetic field generator. The elements are disposed on the mounting structure at locations and orientations relative to each other. The field generator includes at least one covering formed over the mounting structure, wherein, in use, the locations and orientations of the elements relative to each other remain substantially unaltered after exposure to one or more sterilization processes.

An orthopaedic aiming device system is provided that includes a targeting device. The targeting device has a curved portion with an end and at least one guide opening formed therethrough. The curved portion also defines an arced axis. Connected to the end of the curved portion is a mounting portion that has at least one mounting opening formed therethrough. The mounting opening defines a mounting axis that is approximately orthogonal to at least one point on the arced axis of the curved portion. The orthopaedic aiming device system can also include mounting pins, a positioning device, and an orthopaedic implant. The mounting pins can include distancing features that interact with distance locking features of the mounting opening(s) to properly distance the targeting device from the orthopaedic implant. Also included is a method to target implant openings that have compound angled screw trajectories using an orthopaedic aiming device system.

This disclosure presents a MITLIF procedure. The procedure uses a single incision on one side and pedicle screws are placed on that side and through the same incision a facet screw is placed on the opposite side using a series of jigs, and, for example, the hole cutter, drill, guide shaft and screw driver described herein.

A system for robot assisted surgery can include an imaging device configured to capture an image of an implanted device and a probe. The implanted device can define a hole and the probe can define a hole. The system can also include a robot configured to align a fastener to the hole defined by the implanted device. The system can further include at least one memory that includes computer program instructions and at least one processor. The at least one memory and the computer program instructions can be configured to, with the at least one processor, perform obtaining a position and orientation of the hole defined by the implanted device. The at least one memory and the computer program instructions can also be configured to, with the at least one processor, perform aligning the fastener to the hole using the obtained position and orientation.
