Embodiments herein are generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. In some embodiments, these implants and implant trials may be used in conjunction with corpectomy procedures.

An implant assembly including a curved mesh cage and angled endplates. The implant assembly offers a safe and secure mesh cage while providing lordosis/kyphosis angling at the center of the construct instead of at the end of the cage only. One or more angled endplates may be included which allow the surgeon to make a construct unique to the patient's anatomy. The endplates press-fit into corresponding holes in the mesh cage for a secure fit.

An acetabular hip implant includes a plurality of rings secured to an acetabular shell component. A method of fabricating a customized, patient-specific version of such an implant is also disclosed.

A bone implant composition and methods thereof include bone material made into various implant shapes including a cylinder having an outermost layer and an inner layer completely surrounded by the outermost layer. The bone implant compositions and methods include a bag or cylindrical tube made from a bone material which may be filled with additional bone material.

The present invention relates to an expandable prosthetic implant device for engagement between vertebrae generally comprising an inner member, outer member, and gear member 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.

Coiled spinal implants for disc, vertebral body, and spinal motion segment replacement or reconstruction comprise a plurality of loops and spaces between the loops, with the loops formed of a hollow material and having a plurality of apertures or a longitudinal gap that extend(s) through the sidewalls of the loops and into the hollow center. The coiled implants include one or more balloons within the hollow center, the spaces between the coil loops, and/or within the central void that the coil surrounds. Filling the balloon expands the loops and thereby increases the height of the coil. Bone graft material or bone cement may be deployed from the apertures or gap.

A stemless humeral component for replacing the humeral head of a patient's humerus includes a support flange having a number of cantilevered legs extending distally away from a bottom surface thereof. Instruments and methods for surgically installing the stemless humeral component are also disclosed.

A central inflatable distractor and a perimeter balloon are inserted into the disc space in uninflated configurations. The central inflatable distractor is then expanded, thereby distracting the vertebral endplates to the controlled height of the central inflatable distractor. The perimeter balloon is then inflated with a curable substance. The perimeter balloon expands as it is filled with the curable substance and conforms to the void remaining in the disc space around the central inflatable distractor, thereby creating a horseshoe shape. Once the flowable material in the perimeter balloon has cured, the central inflated distractor can be deflated and removed. The remaining void (or inner space) is then packed with graft for fusion.

A device for ligament reconstruction includes an elongated body and a hook or loop at each end for receiving a ligament reconstruction member such as an allograft or autograft tendon. The ligament reconstruction member is positioned within a hole that is drilled into a bone, or which is provided within a prosthetic joint. A central portion of a ligament reconstruction member is passed through each end of the device. The ends of the ligament reconstruction members are then fastened to the opposing bone forming the joint.

Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of the SI-joint and/or lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, SI-joint fusion or fixation; lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.
