Unitarily formed expandable spinal implant and method of manufacturing and implanting same
A unitarily formed expandable spinal implant for insertion in a disc space between two adjacent vertebrae. The unitarily formed expandable spinal implant is moveable from an unexpanded configuration to an expanded configuration, and can be manufactured by a 3-dimensional printer. The unitarily formed expandable spinal implant includes an upper portion, a lower portion, a proximal wall, a first distal wall portion, a second distal wall portion, and a separator connected by at least one point of attachment to the spinal implant. A separation tool breaks the separator free from the at least one point of attachment, and moves the separator within the implant to force expansion thereof from the unexpanded configuration to the expanded configuration.
STABILIZING VERTEBRAE WITH EXPANDABLE SPACERS
A spinal distractor and stabilizer has resilient, conformable bone contacting sections which are separated by an expandable chamber that extends from one of the sections, and which forms a ratchet with the section, ensuring that once expanded by being filled with a substance, cannot contract absent intervention by a medical practitioner. The stabilizer may be filled with a material which solidifies, after which some or all of the device may biodegrade. The device may also be provided in separable portions to facilitate implantation. The conformable sections distribute the distraction and stabilizing force evenly over the bone surface, reducing the incidence of disruption to the integrity of the bone.
Unilateral moveable interbody fusion device and method of use
An interbody fusion device including a body member, at least one side member engaging the body member, and at least one movement mechanism that engages at least one side member and the body member. A surgical method for maintaining a space between two vertebral bodies in a spine, including the steps of obtaining a medical device, such as an interbody fusion device, and inserting and coupling an expansion tool into an opening within the medical device. The surgical method also including slidingly inserting the medical device into a space between two vertebral bodies and rotating the expansion tool to move the at least one side member in a direction relative to the body member. The method may further include detaching the expansion tool from the medical device and removing the tool from the space between the two vertebral bodies in the spine.
BODILESS BONE FUSION DEVICE, APPARATUS AND METHOD
A bodiless bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bodiless bone fusion device comprises one or more extendable plates, one or more extending blocks in communication with the extendable plates, one or more positioning elements for adjusting the extendable plates by manipulating the extending blocks, and one or more support panels for holding the positioning elements and guiding the extendable plates. The plates are able to be advantageously positioned in the confined space between the vertebrae to help brace the device until the bone has fused.
SPINAL IMPLANT SYSTEM AND METHOD
A method of treating a spine includes implanting a spinal implant within a patient. The spinal implant includes a first member having a first wall defining an axial passageway and a first opening, the first opening being in communication with the axial passageway. A second member includes a second wall defining an axial channel having the first member disposed therein, the second wall defining a second opening in communication with the axial channel. Bone graft is injected through the first opening and into the axial passageway and through the second opening and into the axial channel after the spinal implant is implanted within the patient.
Intervertebral implant with improved shape of the fixing plate
An intervertebral implant (100) for the fusion between two vertebral bodies of a vertebral column comprising: a fusion cage (1), extending from a posterior side to an anterior side, adapted to be interposed between two adjacent vertebral bodies of a patient; an asymmetrical fixing plate (2), attached to the fusion cage (1) and having a plurality of passageways (16; 7) for the insertion of bone screws on a single side.
Methods of fusing a sacroiliac joint via a cranial access
A method of fusing a sacroiliac joint including implanting a joint implant into the sacroiliac joint such that the joint implant passes through a cranial access region, the joint implant having an implanted position in the sacroiliac joint such that a portion of a body of the joint implant is positioned within a cranial portion of the sacroiliac joint.
BODILESS BONE FUSION DEVICE, APPARATUS AND METHOD
A bodiless bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bodiless bone fusion device comprises one or more extendable plates, one or more extending blocks in communication with the extendable plates, one or more positioning elements for adjusting the extendable plates by manipulating the extending blocks, and one or more support panels for holding the positioning elements and guiding the extendable plates. The plates are able to be advantageously positioned in the confined space between the vertebrae to help brace the device until the bone has fused.
Unidirectional dynamic interbody fusion device and method of use
An interbody fusion device includes a top member, a base member, and an expansion member. The top member includes a first bone-engaging side and a threaded opening. The base member is received by the top member and includes a second bone-engaging side and an open cavity aligned with the threaded opening of the top member. The expansion member is disposed within the open cavity for rotation about an axis. The expansion member includes a threaded portion threadably engaged with the threaded opening. Rotation of the expansion member translates the first bone-engaging side away from the second bone-engaging side along the axis.
Low profile plate
The present application generally relates to orthopedic systems, and in particular, to systems including independent plates and spacers. A plating system can include a spacer and a plate that is independent from the spacer. A number of locking mechanisms can be provided to secure the plate to the spacer. In some cases, the spacer includes a pair of notches that extend on an outer surface of the spacer. The plate can include a pair of lateral extensions that can engage the notches to secure the plate to the spacer. In other cases, the spacer includes an opening including a pair of inlets. The plate can include an enclosed posterior extension that can be received in the pair of inlets to secure the plate to the spacer.
