An anterior lumbar interbody fusion device comprising a superior component, an inferior component, and a locking mechanism. The superior component bottom side and the inferior component top side oppose each other when these are received in the intervertebral space whereby their external sides abut against the respective vertebra, thereby coupling force between the latter. The components inter-engage with each other whereby they are constrained to move in an anterior-posterior direction relative to each other and resistance is presented to movement relative to each other in each of a direction of separation and a direction orthogonal to the anterior-posterior direction and to the direction of separation. The locking mechanism allows for relative movement of the components in the anterior-posterior direction which increases an extent of their overlap and presents resistance to movement of the at least one of the component in the anterior-posterior direction which decreases an extent of their overlap, for instance with a mechanism such as protrusions shaped to engage with set of recesses and sprung cantilever beams forming a ratchet mechanism. Optionally, the fusion device may comprise or lack a core component received between said superior and inferior components.

An orthopedic implant which generally includes a frame structure and a porous structure. Both the frame and porous structure at least partially define at least six surfaces which make a three-dimensional profile of the implant. The porous structure is positioned at least partially within the three-dimensional profile.

A multi-member prosthesis including first and second elongated members and a central member, said multi-member prosthesis adapted to be advanced into a pilot SI joint opening in said dysfunctional SI joint via a posterior approach, the pilot SI joint opening comprising a sacrum opening and an ilium opening and a sacrum opening. The first elongated member adapted to be press-fit into the sacrum opening and the second elongated member adapted to be press-fit into the ilium opening. The central member including first and second elongated member securing means adapted to secure the first and second elongated members thereto.

An interbody spinal cage comprising: a body portion comprising a superior side, an inferior side and at least one lateral side connecting the superior side and the inferior side; and at least one endplate portion coupled to the superior side or the inferior side of the body portion, the at least one endplate portion comprising a unibody structure and operable to be fixedly coupled to an anatomical structure of a patient and decoupled from the superior side or the inferior side of the body portion.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

Spinal tissue distraction devices that include a member which has a pre-deployed configuration for insertion between tissue layers and a deployed configuration in which the member, by change of configuration, forms a support structure for separating and supporting layers of spinal tissue.

Thoracic/lumbar and cervical spinous process staples which staple/fuse adjacent spinous processes are disclosed. Thoracic/lumbar transverse process staples which staple/fuse adjacent transverse processes are also disclosed. Each embodiment has upper and lower claws connected by a ratchet spring mechanism, along with a multiplicity of bone fastener prongs attached to the upper and lower claws. Two sets of prongs on each staple claw are spaced by a distance approximately equal to the distance separating adjacent spinous or transverse processes so as to facilitate stapling/fusion of two adjacent processes. Also disclosed are staple prongs with multiple perforations which enable incorporation of bone fusion material thereby facilitating stapling/fusion of spinal elements.

Shapeable porous metal implants and methods for use in various procedures are disclosed. The implants can comprise a shell according to some examples. According to one example, the method can include providing a sheet of highly porous metal material having a porosity of between 55% and 90%, and wrapping the sheet of highly porous metal material around at least a first bone of the patient. Further examples can form the sheet intra-operatively to a desired shape. In an example, the porous metal sheet can be formed of tantalum or tantalum alloys.

A method of implanting a glenoid assembly, includes forming a first bore in a glenoid region of a scapula and inserting a first peg of a glenoid component into the first bore. The method includes plastically deforming a first passageway within the first peg, while the first peg is inserted into the first bore, by inserting a first stiffening pin into the first passageway.

A humeral implant component connectable to another humeral implant component, the humeral implant component comprising: a longitudinal axis, a first end and a second end, the first end and the second end opposing each other along the longitudinal axis of the humeral implant component, and an interface part for connecting the humeral implant component to the other humeral implant component, wherein the interface part is tapered along the longitudinal axis in a direction from the second end to the first end, the interface part being engageable with a tapered interface part of the other humeral implant component to form a tapered connection between the humeral implant component and the other humeral implant component, wherein the humeral implant component further comprises a through hole extending along the longitudinal axis for locking the tapered connection by a longitudinal fastener.
