A method of making an implantable device includes directing a projection of laser energy having a plurality of adjacent energy pixels on a build surface atop a bed of powder, thereby forming a layer of the implantable device. The directing step is repeated a plurality of times, in a layer-by-layer manner, such that a totality of the formed layers define at least a portion of the implantable device.

System, including apparatus and methods, for ankle fusion using a device for separating a first bone and a second bone of an ankle region. In some embodiments, the device may comprise an expandable spacer including first and second bone-contacting surface regions facing away from one another and configured to be abutted with the first and second bones, respectively. A distance between the first and second bone-contacting surface regions may be adjustable to change the separation of the first and second bones. The first bone-contacting surface region may correspond to a portion of a sphere and may be configured to be disposed at least partially in a concavity formed surgically in the first bone. The expandable spacer offers improved control over the length of the lower limb and the orientation of the foot during ankle fusion surgery.

A radiocarpal wrist joint replacement includes a radial member configured to be affixed to a portion of an end of the radial bone proximal to the wrist including a fixture to be affixed over a longitudinal aspect of the radial bone and a radial resurfacing plate having a substantially concave surface configured to be located at the end of the radial bone. A carpal capitate bone insert configured to be inserted and affixed into the carpal capitate bone. A bulbous component includes a first convex head and a second convex head, substantially opposite each other and connected by a neck between the first and the second convex head. The radial resurfacing plate of the radial member with the concave surface is configured to be operably coupled to the second convex head of the bulbous component so as to allow radial freedom of motion in the joint replacement.

An expandable implant having superior and inferior endplates disposed on opposite sides of a core is disclosed. The superior endplate may include a first screw engagement surface disposed on a proximal end thereof and the inferior endplate may include a second screw engagement surface disposed on a proximal end thereof. A pin may extend through corresponding pin apertures of the superior endplate, the inferior endplate, and the core. In various embodiments, the superior endplate and inferior endplate are hingedly connected to the core via the pin. The implant may include a locking screw movable between a locked position and an unlocked position. In the locked position, the locking screw may urge an engagement surface of the superior endplate and inferior endplate such that corresponding interior surfaces of the superior and inferior endplates frictionally engage against a corresponding exterior surface of the core.

An implant insertion tool for use during a surgical procedure to implant an acetabular cup component into a surgically-prepared acetabulum of a patient's hip includes a metallic elongated shaft, a removable polymeric grip, and a locking nut to secure the grip to the elongated shaft. Such a modular design allows the implant insertion tool to be dissembled prior to sterilization.

The present disclosure is directed offset adapters, trial implant systems, shoulder implant systems, and methods for total shoulder replacement, wherein the eccentricity of a humeral head relative to a humeral anchor and resected proximal portion of a humerus is selectable by a surgeon. A humeral head implant system includes a humeral head, an adapter, and humeral anchor. An offset adapter is operable to connect the humeral head to a humeral anchor. The offset adapter includes a first tapered cylindrical portion having a first axis, a second tapered cylindrical portion having a second axis, and the first axis being eccentrically disposed relative to the second axis of the adapter. A trial humeral head system includes a trial humeral head, a pin guide, and a trial adapter.

A system and method for providing a spinal implant having a main body, a proximal anchor, a distal anchor, and an internal plunger. The proximal anchor comprises a nut having an internal bore. The distal anchor comprises a plurality of wings having a first closed configuration and a second open configuration. The internal plunger is housed within a central bore of the main body. The distal end of the internal plunger is operatively connected to the first wing and the second wing to selectively move the wings between the first closed configuration and the second open configuration, and vice versa.

An orthopedic implant system is disclosed comprising a staple and a coupling device configured to position tines on the staple relative to a bone to secure an orthopedic implant device to the bone. The orthopedic implant system may comprise the orthopedic implant device also having a wedge and a plate having an external surface configuration. The coupling device may couple the wedge, the plate and the staple whereby when the orthopedic implant is secured in a vertebral body, the external surface configuration of the plate alters the relative orientation of a superior endplate surface plane and an inferior endplate surface plane of the vertebral body and alters the alignment of the spine. In some embodiments, plate tines and staple tines are configured to engage the vertebral body. In some embodiments, the implant device may be used as an arthrodesis device, an intravertebral device or an intervertebral implant device.

An implant including first and second end plates, each of which defines at least one anterior ramped surface and at least one posterior ramped surface. A posterior actuator is positioned between the first and second end plates and has guiding ramp surfaces which correspond with the posterior ramped surfaces. An anterior actuator is positioned between the first and second end plates and guiding ramp surfaces which correspond with the anterior ramped surfaces. An actuator assembly extends between the posterior actuator and the anterior actuator and is configured to selectively move the posterior actuator and the anterior actuator simultaneously, move posterior actuator independently of the anterior actuator, or move the anterior actuator independently of the posterior actuator.

In a tibial component, a tibial block is fixed to a keel portion of a tibial tray. Accordingly, an augment member can be easily attached to the tibial tray without a through hole being formed in the tibial tray.
