Abstract: An expandable anterior lumbar interbody fusion device comprises a deformable monolithic body having posterior and anterior ends, an upper bone contact structure and a lower bone contact structure. The body is expandable along a height axis between a first smaller height to a second larger height. The body comprises a pair of opposed side structures, each including a translatable center section being movable in a direction transverse to the height axis, a first locator arm adjacent the posterior end, a second locator arm adjacent the anterior end and a pair of formable load-bearing columns supported by the upper bone contact structure, the lower bone contact structure and the center section. The columns are not formed at the first height but are operative upon expansion of the body to the second height to form load-bearing columns along the height axis between the upper and lower bone contact structures.

Abstract: Targeting assemblies for implanting a compression nail are disclosed. An exemplary targeting assembly may include first and second arms coupled by a connecting shaft. The first and second arms may either or both be operable to rotate about a longitudinal axis defined by the connecting shaft.

Abstract: A translating polyaxial bone anchor for anchoring a connecting rod to a spinal vertebra comprises a fastener having a bone engaging portion and a head, the head defining a socket. An insert is captively retained in the socket and configured for swiveling polyaxial movement therein. The insert includes an elongate connecting element defining an axis, the connecting element projecting outwardly from and through the socket. A yoke having at one end a rod receiving channel for receiving a connecting rod is coupled to the fastener by a coupling member. The coupling member couples the yoke to the insert connecting element for joint polyaxial movement relative to the fastener and for translational movement of the yoke in a direction transverse to the axis of the connecting member. A fastening element is supported by the yoke for securing the connecting rod between the fastening element and the coupling member.

Abstract: A mold for forming a prosthesis is disclosed. The mold can include a stem portion, a head portion, and a securement assembly. The stem portion and the head portion can be provided in a kit having a variety of different interior dimensions so that a user can select or customize a mold cavity size based on the dimensions of a particular implant site of a patient. While a set of stem portions and head portions can have interior dimensions of varying sizes, each of the stem portions and each of the head portions can have the same or similar exterior dimensions for attachment using a common securement structure. Related methods are also disclosed.

Abstract: Orthopedic implant devices are positioned at a desired in vivo site by positioning a device that is non-rigid, i.e., flexible and/or malleable, in a first form, and then transformable after insertion to the in vivo site into a rigid, or hardened, form for providing a load-bearing function or providing other structural and/or mechanical function after implant. The device includes a biocompatible sheath and a curable material sealed within the sheath. The curable material is provided in a first form that provides flexibility to the device and is structured to rigidize in a second form after application of a quantity of an initiating energy to the material.

Abstract: A device is provided that is non-rigid, i.e., flexible and/or malleable, in a first form, and then transformable after insertion to an in vivo site into a rigid, or hardened, form; a cure-initiating energy is applied to the device; and the device is then positioned in the in vivo site where it hardens to provide a load-bearing function or other structural and/or mechanical function. The device includes a biocompatible sheath and a curable material sealed within the sheath. The curable material is provided in a first form that provides flexibility to the device and is structured to rigidize in a second form after application of a quantity of an initiating energy to the material.
