A knee arthroplasty system may have a femoral joint prosthesis with a femoral bone engagement surface with an anterior portion, a posterior portion, and a distal portion that connects the anterior portion to the posterior portion. A first femoral anchoring member may protrude from the distal portion, and may be connected to the anterior portion with a primary femoral web. A tibial resection guide may have a base member and a guide member with a slot that guides a cutting blade to resect the tibial plateau. The guide member may slide along an arcuate path relative to the base member.

A bone structural device including a plurality of bone structural segments, wherein adjacent bone structural segments are pivotally connected to one another about a pivot axis, and the bone structural segments are expandable in height, which is in a direction generally parallel to the pivot axis.

An inflatable and implantable balloon for treatment of degenerative disc disease, bones, lesions, spinal deformities and spinal motion segment instabilities. The balloon is comprised of adjustable and expandable volumes. Further disclosed are methods of forming, inserting, expanding, and implanting the multi-volume balloon for proper placement and stabilization of the spinal lesion or disease. Still further disclosed are kits for aligning and stabilizing elements of the spine.

A system for dynamically controlling a weld profile includes a generator, and end effector, a sensor, and a computer. The generator is configured to supply energy based on the weld profile. The end effector operatively connected to the generator and configured to apply vibratory energy and pressure to an object. The sensor configured to provide an output with respect to the object. The computer configured to monitor the output and change the weld profile of the generator based on the output.

A mosaic implant (2010) comprises a mesh support frame comprising a plurality of polygonal support rings (2040 A, B, C) connected by a plurality of struts (2014), and a plurality of mosaic plates (2012). The support rings are positioned within the mosaic plates; the struts extend between adjacent plates. An implant (1510) for filling a bore hole comprises a plate (1512) and a support frame (1520) having a central portion (1522) located at least partially within the plate, a polygonal outer rim (1524) having a plurality of fastening points for attaching the implant to bone surrounding a bore hole, and a plurality of arms (1530) extending between the central portion and the outer rim. The plurality of arms extend inwardly and downwardly away from the outer rim such that the central portion is located below the plane of the outer rim and the upper surface of the plate is flush with or slightly above the upper surface of the outer rim.

Implant assemblies, systems, and methods for stabilizing a joint between a superior vertebra and an inferior vertebra may include a plate member coupled to an interbody spacer with at least one fastener that extends superiorly or inferiorly from the implant assembly to anchor within a vertebral body and stabilize the joint. Inserters and methods of insertion may also be included to facilitate fixation of various implant assemblies within the intervertebral space of the joint between the superior vertebra and the inferior vertebra.

An orthopaedic implant includes an implant body having a first surface, a second surface opposite the first surface, and a cavity formed therein that extends through the first surface and the second surface. The implant body has a third surface with at least one first opening formed therethrough to the cavity. The at least one first opening includes an outer portion having an outer diameter and an inner portion having an inner diameter. The implant includes a load bearing member including a porous material held within the cavity. The outer portion of the at least one first opening is configured to couple to a tool for receiving, from the tool, a material agent, and the inner portion of the at least one first opening is configured to couple to a plug for preventing the material agent from exiting the porous material via the at least one first opening.

An inflatable and implantable balloon for treatment of degenerative disc disease, bones, lesions, spinal deformities and spinal motion segment instabilities. The balloon is comprised of adjustable and expandable volumes. Further disclosed are methods of forming, inserting, expanding, and implanting the multi-volume balloon for proper placement and stabilization of the spinal lesion or disease. Still further disclosed are kits for aligning and stabilizing elements of the spine.

An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

Implants for vertebral body or functional spinal unit replacement comprise a bioactive surface roughening on one or more of the anterior, posterior, and lateral surfaces of the implant. The bioactive surface includes macro-, micro-, and nano-scale structural features that contact vertebral bone that lines a specialized channel in a vertebrae, and thereby facilitate bone growth and osteointegration of the implant with the vertebral bone.
