Various surgical devices and methods are disclosed herein. Also disclosed is multi-component prosthesis, which can be used as an ankle prosthesis. One of the disclosed surgical alignment systems includes a guide arm, a ratchet arm frame configured to be coupled slidably to the guide arm, a ratchet arm configured to be coupled to the ratchet arm frame, and a sagittal sizing guide body configured to be coupled to the ratchet arm. The sagittal sizing guide body includes a first radiopaque object disposed at a first position and a second radiopaque object disposed at a second position that is spaced apart from the first position.

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a grommet which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the grommet and the clip.

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 patient-specific cutting guide system comprises at least two instruments. One is a positioner configured to locate a fiducial marker on a patient's bone and to be secured in three axes. The second is a cutting guide that cooperates with the positioner and delineates cuts to be made. The instruments are designed from images of the bone with the marker already in place. Preferably, a positioner comprises at least three targeting apertures configured to locate at least three non-linear markets. The cutting guide comprises top surface contours that guide the depth of the cuts. A method of forming this system comprises placing at least one marker (preferably three) on a patient's bone, then imaging the bone, forming a positioner designed to incorporate the marker position, and forming a cutting guide configured to be oriented and anchored by the positioner.

Systems and methods for treating musculoskeletal disorders of the spinopelvic anatomy including treating spinal deformities by spinopelvic fixation including fusion of the sacroiliac joint at the base of long spinal fusion construct cases. The system may include implants designed to be used as an adjunct to long spinal fusions to further the immobilization and stabilization of the sacroiliac joint. The implants may be designed to augment an S2AI screw and an S1 screw in order to improve durability of the foundation of the spinal construct. The implants may have a triangular cross section.

Methods, systems and devices for pre-operatively planned shoulder surgery guides and implants. Pre-operative planning methods for designing a shoulder surgery guide based on considerations of multiple factors affecting the outcome of shoulder surgery. Methods of using surgery guides and implants in patients undergoing shoulder surgery.

Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.

A bone displacement system includes a body having a first arm and a second arm. The first arm is coupled to a first bone contacting leg configured to be connected to a first bone portion. The second arm is coupled to a second bone contacting leg configured to be connected to a second bone portion. A force application fixture is coupled to the first arm and the first bone contacting leg and configured to apply a force between the first arm and the first bone contacting leg.

A system for performing a minimally invasive interventional fusion procedure on a sacroiliac joint of a patient. The system may include a disposable sterile packed implant and kit including access, bone cutting, accessory and extraction instruments.

Surgical constructs, assemblies and methods of tissue fixation are disclosed. A self-positioning drill guide can automatically reference a drill point or drill angle for drilling tunnels in bones by using peripheral edges. A self-positioning drill guide can be a center point drill guide configured to automatically center drill tunnels in bones by using peripheral edges that precisely reference the center point. A centering guide helps to automatically determine the center of bones as well as to provide increased control during drilling.
