A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft can be movably connected to the main body member and have the bone engagement member rotatably coupled to its distal end. The bone engagement member can have a surface configured to engage a bone. The main body member can also include a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.

A surgical apparatus includes an instrument portal including a first proximal end, a first distal end, and a first elongated member, the first elongated member defining a first bore having a first dimension, wherein the first bore extends from the first distal end to the first proximal end, wherein the maximum clearance of the instrument portal is the first dimension and a drill guide reducer configured to be inserted into the instrument portal, the drill guide reducer including an elongated cylindrical member defining an enclosed body surrounding an opening, the enclosed body having an outside dimension that is smaller than the first dimension, such that the drill guide reducer is sized to fit within the instrument portal and defining an inner dimension configured to receive a drill guide, wherein the inner dimension of the drill guide reducer is smaller than the first dimension of the instrument portal.

A surgical system is provided. The surgical system includes a camera operable to capture images and/or video. A projector is operable to project light, and a controller is communicatively coupled with the camera and the projector. The controller is operable to track movement of bone in real-time during surgery based on the images and/or video captured by the camera, and control the projector to project the light including a cutting line on the bone to indicate a cutting plane for cutting the bone during surgery.

Embodiments described herein provide an implant for rigid intramedullary fixation of the hindfoot complex with the midfoot and/or forefoot and methods of implanting the same. Embodiments described herein can allow for the implant to be adapted to the patient based upon the extent of bone loss and instability. Embodiments herein also provide a jig system to facilitate the shaping of the foot and/or the implantation of the described internal fixation systems.

A complete removal and reinsertion of instruments is avoided when the instruments are initially not correctly positioned during a minimally invasive operation on a bone, in particular a vertebra of the spine. This aim is achieved by an instrument set for spinal operations, including a guide rod, which has a cavity extending along the axis of the guide rod, and a guide tube, which can be received in the cavity of the guide rod, wherein the guide rod has a distal lip, which is arranged eccentrically to the cavity and/or to a center axis of the guide rod.

Guides, instruments, devices, systems and methods for maintaining, correcting and/or resurfacing the multiple bones of a joint are disclosed. The guide system includes a cut guide and an alignment guide for engagement with the cut guide. The guide system also includes a cleaning system with a guide and a cutting instrument. Methods of using the guide system and cleaning system are also disclosed.

In one aspect, the present disclosure provides a monolithic percutaneous-screw system for use in spinal surgery. The system includes (i) a receiver having a distal base and a pair of opposing arms extending proximally from the base, a pair of opposing distal breakoff sections, each connected monolithically to a proximal end of a corresponding one of the arms, (ii) a pair of opposing proximal breakoff sections, (iii) a pair of opposing intermediate extenders, each extending from a distal end, connected monolithically to a corresponding one of the distal breakoff sections, to a proximal end connected monolithically to a corresponding one of the proximal breakoff section, and (iv) a guide cap connected monolithically to both of the proximal breakoff sections.

A bone plate defines an interior surface that defines: a hole extending through the plate along an axis; plate threads configured for locking with a threaded head of a locking screw; first, second, and third columns sequentially located about the axis; a first corner extending tangentially from the second to the first column; and a second corner extending tangentially from the third to the first column. The first and second corners are substantially equidistantly spaced from the axis. The plate threads extend across the first, second, and third columns and the first and second corners. The interior surface defines a recess between the second and third columns and facing the first column. An apex of the recess is spaced further from the axis than are the first and second corners, such that the recess circumferentially interrupts at least a portion of at least one of the plate threads.

A freely-connectable three-strut parallel orthopedic external fixator including two fixation rings and three struts, connecting holes are circumferentially and uniformly distributed on the ring surfaces of each fixation ring, each strut is provided with two driving translational pairs, a revolute pair and a spherical pair. Two fixation rings are respectively fixedly connected with the bone segments of the fracture site by using medical metal bone pins; adjusting the driving translational pairs of the six struts can achieve six DoF relative movement of the two fixation rings, thereby achieving fracture reduction. The external fixator of the present invention realizes free connection between the two fixation rings, which facilitates fixator installment; number of struts is less than the existing external fixators.

A driver for engaging an endcap of an intramedullary nail. The driver includes a handle extending along a longitudinal axis of the driver from a proximal end to a distal end. The handle having a handle channel extending longitudinally therethrough. The driver also includes a shaft extending through the handle channel from a proximal end to a distal end along the longitudinal axis. The shaft having a shaft channel extending longitudinally therethrough. The distal end of the shaft extends distally from the handle. The distal end of the shaft forms a driving element to be inserted into a head portion of the endcap. The driver further includes a retention pin slidably received in the shaft channel. The retention pin extends also extends along the longitudinal axis. The distal end of the retention pin is configured to reversibly lock the shaft to the head portion of the endcap.
