One embodiment of the present disclosure provides a humeral implant. The humeral implant includes a tray including a body defining a bone facing recess and a liner recess, said bone facing recess including a ring surface and a convex surface, wherein the ring surface has a profile substantially corresponding to a profile of an outer ring of bone in an excision site of a patient; and wherein said convex surface has a profile substantially corresponding to a profile of a concave socket formed in the excision site. The humeral implant also includes a liner including a body defining a load bearing surface and a tray interface surface, said tray interface surface being configured to be at least partially received in said liner recess of said tray such that said implant is coupled to said tray.

An implant trial head includes a distal end, a proximal end including an opening in an exterior surface, and a cavity extending from the opening into the implant trial head. The cavity includes an asymmetric groove in an interior wall of the cavity, the groove aligned substantially perpendicular to a longitudinal axis of the implant trial head, and a cross-sectional diameter of the asymmetric groove. The implant trial head includes an O-ring positioned in the asymmetric groove.

A surgical instrument and method are provided for removal of a spinal implant from the intervertebral disc space. The instrument includes a carriage body for interfacing with the implant, a housing for interfacing with the vertebrae, and a handle portion having a first portion rotatably coupled with a proximal end of the housing and a second portion rotatably engageable with a proximal attachment portion of the carriage body. A central passage of the housing extends between the proximal end and a distal engagement surface of the housing. The central passage is dimensioned to mate with the carriage body. Rotation of the handle portion about an axis causes translational movement of the carriage body along the axis. A modular inserter/distractor apparatus and method and an anchor remover and method are also provided.

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

Devices, systems, and methods for a robot-assisted surgery. Navigable instrumentation, which are capable of being navigated by a surgeon using the surgical robot system, and navigation software allow for the navigated placement of interbody fusion devices or other surgical devices. The interbody implant navigation may involve navigation of access instruments (e.g., dilators, retractors, ports), disc preparation instruments, trials, and inserters.

Systems and methods are provided for determining acceptable ranges of pressures for use by a robotic arm on a surgical instrument, robotic systems and methods that are limited to using the acceptable ranges of pressures, and the medical devices for use in the robotic surgery. Learning software is included in the methods and systems for correlating manually-performed procedures with pressure sensors as a tactile gauge for qualifying the acceptable ranges of pressures for use by a robotic system. Robotic systems and methods are provided for (i) locating tissue borders of a surgical site, (ii) identifying a preferred pressure, and (iii) transmitting the data to the computer to avoid violating the integrity of tissue surrounding the surgical site.

A method for preparing a femur for receiving a prosthesis. The method includes the following: fixing a femoral trial component to the femur; coupling a reamer bushing relative to the femoral trial component; reaming a cavity into the femur using the reamer bushing as a guide; coupling at least one of a modular femoral box trial and a stem adapter relative to the femoral trial component; trialing the femoral trial component with the articulating surface of the femoral trial component; and performing the coupling of the reamer bushing, the reaming of the cavity, the coupling of the at least one of the modular femoral box trial and stem adapter, and the trialing of the femoral trial component all while the femoral trial component remains fixed to the distal femur.

Hip arthroplasty trial systems and associated medical devices, methods, and kits are described that can be utilized in situ to complete a femoral head trial. An example embodiment of a hip arthroplasty trial system includes a medical device and a femoral stem. The medical device has a head member, a spacer, a shaft, and a locking member. The spacer is disposed within the head member and is moveable from a first position to a second position. The shaft is disposed within the head member and contacts the femoral stem. The shaft is moveable from a first position to a second position. Movement of the shaft from the first position to the second position moves the spacer from its first position to its second position. The locking member is disposed within the head member and releasably attaches the shaft to the head member.

A system for harvesting bone material from a bone may include a rotary cutter defining a rotary cutter longitudinal axis extending between a rotary cutter proximal end and a rotary cutter distal end. The rotary cutter may have a drive shaft configured to receive input torque, and an osteochondral cutter configured to cut the tissue and receive the tissue material in response to rotation of the osteochondral cutter under pressure against the tissue. The system may further include a bone port defining a bone port longitudinal axis extending between a bone port proximal end and a bone port distal end. The bone port may have a bone port cannulation sized to closely fit over the osteochondral cutter. At least one of the bone port proximal end and the bone port distal end may be securable to the tissue. A stratiform tissue graft may be delivered through the bone port.

The present disclosure relates to a tibial component for an endoprosthetic knee implant comprising a tibial baseplate and a keel extending from a lower surface of the tibial baseplate. The tibial baseplate is disposed at a keel posterior angle relative to the keel, and the tibial baseplate is also disposed at a keel varus angle relative to the keel. The disclosure further describes modular keel embodiments, exemplary instruments that can be used to implant exemplary tibial components into and onto the proximal tibia, methods related thereto, and kits therefore.
