Various embodiments of filling assemblies and methods are provided. The filling assembly can include a barrel and receiving block assembly configured to couple to a tube. The filling assembly can include a filling auger, wherein the filling auger is configured to rotate and translate to fill the tube with material. The method of filling a tube can include disposing flights of a filling auger within a barrel and receiving block assembly. The method can include coupling a tube to the barrel and receiving block assembly. The method can include rotating and translating flights of the filling auger within the barrel and receiving block assembly to fill the tube with material. The filling assemblies can be utilized for loading material into small diameter tubes, including small diameter tubes used for spinal

The disclosure provides an articular fossa prosthesis and an articular prosthesis with the articular fossa prosthesis. An outer cup of the articular fossa prosthesis is disposed in a target skeleton, a lining is disposed in the outer cup, an articular head structure may be movably disposed in the lining, a first communicating passage communicated with an articular capsule is disposed on the outer cup, a second communicating passage communicated with the articular capsule is disposed on the lining, and the first communicating passage is communicated with the second communicating passage to guide a synovial fluid to a contact surface between the lining and the articular head structure.

A method of placing an implant for intervertebral fusion between adjacent vertebral bodies in a patient includes inserting the implant in a space between the adjacent vertebral bodies such that both a first intervertebral spacer body and a second intervertebral spacer body contact each of the adjacent vertebral bodies. The first intervertebral spacer body is spaced apart from the second intervertebral spacer body. An expandable container portion of the implant disposed between the first intervertebral spacer body and the second intervertebral spacer body is filled with fill material such that the expandable container expands to contact each of the adjacent vertebral bodies.

A joint spacer is provided for treatment of a joint of a human subject, the joint spacer including a pouch having a wall including a dermal graft material. The joint spacer is configured to be inserted into a space of the joint, and is shaped, when the pouch is inserted into the space and filled, to provide mechanical support to the joint. Other embodiments are also described.

Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.

Systems, devices and methods for providing orthopedic augments having recessed pockets that receive a fixation material. The orthopedic augments include an outer surface that interfaces with a patient's tissue or bone, an inner surface that interfaces with an implant and having a recessed pocket configured to receive a fixation material, a rim around at least a portion of the recessed pocket, and a port in the rim, wherein the recessed pocket extends along the inner surface in at least a lateral direction from the port.

The present disclosure relates to a spinal fusion impactor tool that includes an attachment means for securing an implant device to the distal end of the tool, a means for adjusting the angle of the distal head relative to the handle to better position the implant for introduction into the implant site, means for remotely releasing the implant device at the distal end and a clamp device on the shaft of the tool to secure tabs, attachments and other devices. The impactor tool is preferably used in conjunction with implantation of an intervertebral fusion cage that is equipped with shims having tabs or other removing means, but may also be used to introduce, for example, an implant, graft, fusion device, wedge or distractor device into any joint space or bony region in preparation for implantation.

An expandable interbody implant adapted for insertion at least into a disc space, between two adjacent vertebrae of a spine. An upper member and a lower member are pivotally connected at least by a drive link. A bone graft storage portion packed with a selected volume of bone growth material. A translational wall is provided between the bone graft storage portion and a trailing end of the implant. An actuator engages the bone graft storage portion, pushing it forward into engagement with the drive link, which pivots upward, moving the upper member upward away from the lower member. Upward movement of the upper member raises the translational wall to a position to assist in retention of the selected volume bone graft material within the hollow portion of the bone graft storage portion. Upward rotation of the drive link brings a face thereof into contact with a front of the bone graft storage portion, thereby retaining near constant volume of the bone graft material.

An intervertebral scaffolding system is provided having a rigid central beam and a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state.

A joint spacer is provided for treatment of a joint of a human subject, the joint spacer including a pouch having a wall including a dermal graft material. The joint spacer is configured to be inserted into a space of the joint, and is shaped, when the pouch is inserted into the space and filled, to provide mechanical support to the joint. Other embodiments are also described.
