A sacroiliac joint implant system includes a primary implant configured to be received in a sacroiliac joint of a patient and a secondary implant configured to couple with the primary implant. The primary implant includes a body extending from a proximal end to a distal end and a plurality of threads extending from the body. The secondary implant includes a first anchor configured to anchor within a sacrum of the patient and a second anchor configured to anchor within an ilium of the patient.

An embodiment includes an orthopedic fusion system comprising: a cage; a curved first channel coupling a lateral wall of the cage to a superior surface of the cage; a curved second channel coupling the lateral wall of the cage to an inferior surface of the cage; a third channel coupling the superior surface of the cage to the inferior surface of the cage; a curved first anchor configured to slide within the first channel; a curved second anchor configured to slide within the second channel; and a resilient member comprising a resilient first arm that projects across a portion of the first channel and a resilient second arm that projects across a portion of the second channel. Other embodiments are described herein.

The present invention relates to an expandable prosthetic implant device for engagement between vertebrae generally comprising an inner member, outer member, gear member and a locking assembly positioned coaxial with respect to each other such that the inner and outer members are moveable relative to each other along an axis. The gear member is axially fixed to the outer member and freely rotatable with respect to the outer member and the gear member threadedly engages a threaded portion of the inner member to translate inner member along the axis. The implant is configured to engage the vertebrae in a predetermined alignment and the gear member includes gear teeth exposed to the exterior and configured to be accessible by a tool member at a plurality of angular positions around the perimeter of the implant device.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

An adjustable spinal fusion intervertebral implant is provided that can comprise upper and lower body portions that can each have proximal and distal wedge surf aces disposed at proximal and distal ends thereof. An actuator shaft disposed intermediate the upper and lower body portions can be actuated to cause proximal and distal protrusions to converge towards each other and contact the respective ones of the proximal and distal wedge surfaces. Such contact can thereby transfer the longitudinal movement of the proximal and distal protrusions against the proximal and distal wedge surfaces to cause the separation of the upper and lower body portions, thereby expanding the intervertebral implant. The upper and lower body portions can have side portions that help facilitate linear translational movement of the upper body portion relative to the lower body portion.

A spine stabilization device having an interbody spacer shaped to be inserted between a vertebral body of an upper vertebra and a vertebral body of a lower vertebra. The device further includes a fixation device to be inserted after placement of the interbody spacer, the fixation device having a support portion securing the interbody spacer against escaping from between the vertebral bodies into a ventral direction. The support portion rests against a portion of an anterior surface of the interbody spacer, and includes an anchor. The anchor has an anchoring material portion that is inserted, in a liquid state, into cancellous bone tissue of at least one of the vertebral bodies of the upper and lower vertebra, to thereby infiltrate the cancellous bone tissue, and to harden thereafter so as to fix the support portion to the vertebral body.

An apparatus for implanting a medical implant into bone includes: an implant having at least one predetermined natural frequency; and an instrument, comprising: a housing; a coupler carried by the housing and configured to be mechanically connected to a medical implant; and a forcing mechanism carried by the housing and operable to apply a cyclic excitation force at the predetermined natural frequency.

An interbody implant includes an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. At least one of the vertebral engaging surfaces defines a cavity configured for disposal of bone growth detectable via medical imaging. Systems, spinal constructs, surgical instruments and methods are disclosed.

An interbody spacer for spinal fusion surgery includes first and second opposite side walls that have open-cell metal foam at upper and lower faces, and a three-dimensional lattice disposed between open-cell metal foam at the upper and lower faces. The open-cell metal foam is in communication with the three-dimensional lattice so that bone growth can enter the three-dimensional lattice from the open-cell metal foam. The interbody spacer may be formed by additive manufacturing.

A cup impactor (1, 1′, 1″) is provided, adapted to assist a surgeon in controlling implantation of a cup prosthesis (9). The impactor has an impactor body (8), a drive train assembly (71), an impactor nose (38), and a clamping handle (5). The impactor body (8) has on its proximal end, an impaction plate (7) connected thereto, and an impactor handle (6) formed thereon for handling by the surgeon and, on the distal end, an impactor cup support portion (8a) having a receiver recess (8b) therein. A drive train assembly (71) has a prosthesis engaging interface (11) at a distal end thereof, and a proximal end on which a positioning knob (2) is formed. The assembly (71) received and rotatably mounted in the receiver recess (8b) of the body (8) so as to expose the prosthesis engaging surface (11). An impactor nose (38) mounts on the distal end of the impactor body (8), through which the prosthesis engaging interface (11) extends. A clamping handle (5) pulls distal portion of the drive train assembly (71) and therefore any cup prosthesis (9) attached to the engaging interface (11) against the impactor nose (38) so as not to strain the proximal end of the drive train assembly (71).
