Abstract: This disclosure relates to bone fixation plate and a system for treatment of injuries of the distal tibiofibular syndesmosis. The bone fixation plate provides an improved stability to the distal fibula.

Abstract: An exemplary bone screw includes a proximal section including a first outer thread, a center section including a second outer thread, an unthreaded distal section on an opposite side of the center section from the proximal section, a channel extending from the proximal section to a distal opening of the unthreaded distal section, and at least one side opening extending from the channel to an outer surface of the unthreaded distal section. In some embodiments, the at least one side opening includes a cutting edge configured to cut a material as the bone screw is rotated in a direction for removing the bone screw. In other embodiments, the side opening is formed in at least one of the center section and the unthreaded distal section and includes a diameter that increases in a direction from the channel toward an outer surface of the center section or the unthread distal section. The exemplary bone screws may be used to treat bone fractures with or without a bone plate.

Abstract: A talus surface implant has an arc shaped body with a top side interfacing to the tibia and a bottom side having at least one post for interfacing with holes in the talus and a plurality of spikes for interfacing with the surface of the talus. Preferably the implant is double arc shaped.

Abstract: A bone fixation device according to an exemplary aspect of the present disclosure includes a nail extending along a longitudinal axis. The nail is provided with a transverse bore arranged along a transverse axis that intersects the longitudinal axis. The bone fixation device further includes a screw assembly received in the transverse bore, and a locking device. The locking device is configured to clasp the screw assembly to lock the screw assembly against movement along the transverse axis and against rotation about the transverse axis.

Abstract: A bone plate configured to accommodate fixation devices (such as screws, for example) inserted at various angles. The bone plate is formed of a material softer than the material of the fixation devices, and is provided with fixation holes with rounded, curved interior walls (i.e., non-threaded holes) that allow the fixation devices to be inserted at various angles. The fixation holes have a diameter smaller than that of the fixation devices. As a result of the difference between the materials of the plate and of fixation devices, and of the difference between the diameters of the fixation holes and of the fixation devices, the fixation devices deform the interior walls of the fixation holes, therefore self-threading the holes at an advantageous angle.

Abstract: Methods of arthroscopic resurfacing of a joint utilizing a biological component strengthened with fibrin glue. The biological component is selected from the group consisting of PRP, bone marrow aspirate (BMA) and autologous conditioned plasma (ACP). The biological component/fibrin glue composition may be inserted (by injection or by employing a biologic resurfacing mold, for example) into a transosseous tunnel in the vicinity of the defect to be repaired. Upon insertion at the defect site, the biological component/fibrin glue composition is designed to coagulate and solidify within few minutes, to advance the healing of the damaged tissue and tissue growth. The biological component/fibrin glue composition may optionally comprise components such as growth factors, antiseptic chemicals and/or antibiotics and/or electrolytes, or hormones or site-specific hybrid proteins, among others.

Abstract: A humeral component of a shoulder prosthesis encloses a stem module which has a shank and an upper shank portion with a stem support surface. A joint adapter is adapted to hold either a liner or a spherical cap. The joint adapter has an adapter support surface which interfaces with the stem support surface. Further, the stem support surface and the adapter support surface have corresponding radial arc shaped sections which allow positioning of the joint adapter against the stem module at different inclination angles. For fastening the joint adapter to the stem module, a bolt or screw is provided.

The exemplary bone screws may be used to treat bone fractures with or without a bone plate.

Abstract: A surgical guidance system for orthoscopic drilling is disclosed which comprises a probe, the end of which is suitable for locating on the emergence site of a hole to be drilled through body tissue, a targeter comprising one or more sensors for locating the position of the probe, a drill guide, and a control system in communication with the targeter for determining the position of the probe measured by the targeter and providing a real-time visual representation of the relationship between the direction of the drill guide and the tip of the probe to allow the user to align the drill guide to the tip of the probe. The probe comprises an elongate shaft and one or more, preferably two or more markers located at distant positions along the shaft, and wherein further the markers can be detected by the targeter and are each positioned at locations removed from the tip of the probe.

Abstract: An arthroscopic drill guiding system for drilling a hole into a bone comprises an arthroscopic pointing device, a drill sensor and an indicator. The pointing device has a shaft with a distal section and at least one navigation sensor for locating a target position distally at the bone. The drill sensor is coupled to a drill and provides information about the position and/or direction of the drill. The indicator indicates the relative position of the drill with respect to the target position, thus allowing to align the drill with the target position.
