A build-plate with integrally-formed spinal implant constructs and a method used in forming spinal implant constructs on the build-plate and machining the spinal implant constructs formed on the build-plate to manufacture spinal implants is provided. The spinal implant constructs can be formed via additive manufacturing processes by adding material to an upper surface of the build-plate, and then the spinal implant constructs can be subjected to subtractive manufacturing processes to form the spinal implants.

An expandable includes a base member having a top surface and a bottom surface opposite the top surface, and an adjustable member adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position. The adjustable member has a top surface and a bottom surface opposite the top surface. The top surface of the adjustable member and the bottom surface of the base member form a first angle while the adjustable member is in the first, collapsed position, and the top surface of the adjustable member and the bottom surface of the base member form a second angle while the adjustable member is in the second, expanded position. The first angle is different from the second angle.

An implant includes a first support, a second support rotatably coupled to the first support along a distal end of the implant, and a control assembly configured to move the implant between at least a first, collapsed orientation and a second, expanded orientation, the control assembly includes a control driver coupled to the first support and comprising a head and a shaft, the control driver configured to control relative movement between the first support and the second support, a control member configured to move along the shaft of the control driver, and a first linkage hingedly coupled to the control member and the second support, wherein movement of the control member causes the first support to move relative to the second support.

An expandable intervertebral implant having an upper body portion, a lower body portion opposite the upper body portion, a wedge member connecting the upper body portion to the lower body portion, a nose member having a tapered distal end and a proximal end opposite the distal end, and an actuator disposed between the nose member and the wedge member, for translation of the wedge member along a longitudinal axis of the implant. A pin connects to the actuator for positioning the nose member relative to the actuator. Translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the intervertebral implant.

The present invention relates to an implant (1) for the correction of gleno-humeral instability, in particular for the correction of a glenoid defect (Dg) of the glenoid (G) of a patient, said implant (1) having a substantially flat portion (3), said substantially flat portion (3) being suitable, when said implant (1) is in use, for being placed at the site of the glenoid defect (Dg) in contact with the external bone portion of the glenoid (G) of a patient, said implant (1) being characterized in that at least said flat portion (3) is made of heterologous deproteinized bone material.

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.

Various surgical tools having a movable handle mechanism including a positioning handle are disclosed. The movable handle mechanism may be configured to move forward and backward in a longitudinal direction along the housing and rotate clockwise and counterclockwise around the housing. In various embodiments, the housing may include a plurality of channels and each channel may have at least one detent. The movable handle mechanism may be configured to securely couple to the housing via one channel of the plurality of channels and one detent of the plurality of detents. At least one surgical tool may include a drill having an angled tip portion and a sleeve configured to protect adjacent structures from lateral edges of the drill bit when the drill bit is rotating. Another surgical tool may include a screwdriver having an elastic retaining clip configured to progressively release a bone screw therein at an extraction force.

An expandable interspinous process fixation system capable of restoring spinal stability and facilitating fusion. In one embodiment, the expandable interspinous process fixation system includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. Each endplate supporting fixed and/or adjustable spinous process engaging plates.

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

A bone fusion device provides stability to bones during a bone fusion period. The bones include, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs attached to the bone fusion device by associated rotating means. The bone fusion device is preferably inserted by using an arthroscopic surgical procedure. During arthroscopic insertion of the device, the tabs are pre-configured for compactness. In this compact configuration, the tabs are preferably deposed along and/or within an exterior surface of the bone fusion device. After the bone fusion device has been positioned between the bones, one or more tab(s) are extended. In the preferred embodiment, the position of each tab is related to a positioning element and extending blocks. Typically, the tabs advantageously position and brace the bone fusion device in the confined space between the bones until the bones have fused.
