A plate for attaching to an anatomic structure with fasteners. The plate has a body with a top surface and a bottom surface opposite the top surface. The body defines one or more openings to receive a respective one of the one or more fasteners. The bottom surface is concave to define a space to accommodate a portion of the anatomic structure. A bone pad surface extends from the bottom surface. A spike extends away from the bone pad surface. An extension arm can be coupled to the plate and the extension arm can support a tracking head to implement a surgical tracking assembly.

Bone plate for attaching to an anatomic structure

A method of performing surgery on a bone includes providing a robotically controlled bone preparation system and creating at least one hole in the bone with the robotically controlled bone preparation system prior to machining the bone. The bone hole aligns with a hole or a post in a guide for a manual cutting tool. If the robot fails during surgery, or if the surgeon does not wish to complete the procedure with the robot, the guide is attached to the bone after aligning the guide hole with the bone hole. The surgery is completed manually after the guide is attached to the bone, and the robot is not used after the guide is attached to the bone.

A plate for attaching to an anatomic structure with fasteners. A body defines openings for receiving the fasteners, and includes a bottom surface that is concave. The plate includes bone pad surface, and a spike extends away from the bone pad surface. The bone pad surface is oriented at an angle relative to the bottom surface to prevent further penetration of the spike into the anatomic structure beyond a predetermined depth. The bone pad surface may be oriented at an obtuse angle relative to the bottom surface. The bone pad surfaces may be planar or concave, or contoured to a corresponding profile of the anatomic structure. The spikes may be pyramidal or conical. At least one side of the spike may be integral and continuous with the bottom surface. The side may have a radius of curvature equal to that of the bottom surface.

A dynamic trialing method generally allows a surgeon to perform a preliminary bone resection on the distal femur according to a curved or planar resection profile. With the curved resection profile, the distal-posterior femoral condyles may act as a femoral trial component after the preliminary bone resection. This may eliminate the need for a separate femoral trial component, reducing the cost and complexity of surgery. With the planar resection profile, shims or skid-like inserts that correlate to the distal-posterior condyles of the final insert may be attached to the distal femur after the preliminary bone resection to facilitate intraoperative trialing. The method and related components may also provide the ability of a surgeon to perform iterative intraoperative kinematic analysis and gap balancing, providing the surgeon the ability to perform necessary ligament and/or other soft tissue releases and fine tune the final implant positions based on data acquired during the surgery.

Intraoperative dynamic trialing

Disclosed herein are systems and methods of patella arthroplasty. A navigated patella clamp used in an arthroplasty procedure includes first and second movable jaw members and an actuation member coupled to the first and second jaw members for moving the first and second jaw members along a plane toward and away from one another. The patella clamp further includes a tracker and adjustable stylus for positioning the clamp on a patient's patella below a desired resection plane. The adjustable stylus coupled to the clamp is used to check the position and orientation of the clamp with respect to the patella to ensure the correct amount of bone will be resected from the patella corresponding to the thickness of a patella component that will be implanted on the resected patella.

Navigated patella clamp

A limb positioning system includes a clamp assembly, a pylon and bar assembly, a sled assembly, and a limb positioning assembly. The clamp assembly is configured to attach to a bed rail of a surgical table and to accept a pylon connected to a bar. The pylon may have a plurality of pylon bars that are secured by the clamp assembly. A base bar may extend from the pylon, and may be attachable to an extension bar to provide a longer track along which the sled assembly may slide. The sled assembly may be biased to be locked with respect to the base bar. The limb holding assembly may include a boot coupled to the sled via a connector near the heel. The connector may be tapered and insertable into a correspondingly tapered section of a ball that sits within the sled assembly, the ball being capable of polyaxial motion.

Limb positioning system

Disclosed herein is a clamp attachable to a support rail of a hospital bed, for example. The clamp includes a body, first and second arms coupled to the body, wherein the first and second arms are moveable towards and away from one another. The clamp further includes at least one seat clamp member pivotably coupled to at least one of the first and second arms. The clamp is attached to the support rail when the at least one seat clamp member contacts the support rail and the first and second arms are in a clamped position.

Rotatable seat clamps for rail clamp

A limb holder generally includes a limb holder assembly, a sled or yoke assembly, a pylon and support bar assembly, a clamp assembly, and a retractor assembly. A limb, such as a leg, is supported by the limb holder. The limb holder is supported by a sled which can move along a support bar that is supported by virtue of a mounting pylon. The mounting pylon is fixed in place by a clamp assembly, the clamp assembly being attached directly to a bed, table, or other patient support. The limb holder can also receive one or more retractor assemblies capable of retracting an incision, such that a user may manipulate a patient's limb during a procedure in which the use of retractors is desired.
