The present disclosure relates to expandable interbodies that include superior and inferior shells and a control assembly positioned between and inside of the shells, the control assembly including nested cages operably connected to each other with an adjustment screw. Rotation of the adjustment screw translates the cages relative to each other, which in turn causes the shells to open or expand.

A lateral patient positioning system may include a pelvic bolster assembly and a thoracic bolster assembly. Each of the assemblies may be attached to a conventional surgical table frame by the surgical table frame's longitudinal rails. A plurality of adjustment mechanisms and components are provided to allow for easy and safe manipulation of a patient before and during surgery, including sagittal and/or coronal adjustment of a patient in a lateral position.

This disclosure relates generally to mechanical surgical arms having a connector for attaching a surgical tool to the arm across a sterile drape. In various aspects, a drape connector for securing a tool to a surgical arm across a sterile drape includes a flexible collet for receiving a ball of a connection shank of the surgical arm to selectively secure the flexible collet to the surgical arm. The drape connector may also include a lock associated with an inferior end of the flexible collet. The lock may be for adjusting the flexible collet from an unlocked position to a locked position. Further, the drape connector may include a housing for receiving the flexible collet and the lock. The housing defines a window to provide access to the lock to adjust the flexible collet from the unlocked to the locked position.

Disclosed herein are expandable interbodies with modular endplates. An expandable interbody has an outer column, an inner column threadedly coupled and translatable relative to the outer column along the longitudinal axis, and an expansion ring to adjust a body length of the expandable interbody. The expansion ring has a plurality of teeth, and the outer column has at least one arm for engaging a tooth of the plurality of teeth to lock the expansion ring. The inner column and/or outer column can include a connector for connection to a modular endplate that has a substantially hollow core. The modular endplate includes a plate with a set screw entrapped therein. The modular endplate has an aperture to receive the connector of the inner and/or outer column.

An automated EP analysis apparatus for monitoring, detecting and identifying changes (adverse or recovering) to a physiological system generating the analyzed EPs, wherein the apparatus is adapted to characterize and classify EPs and create alerts of changes (adverse or recovering) to the physiological systems generating the EPs if the acquired EP waveforms change significantly in latency, amplitude or morphology.

In various aspects, an expandable implant for use in a surgical procedure includes a distal cage, a proximal cage mechanically connectable with the distal cage, a top expandable assembly, and a bottom expandable assembly. Each of the top and bottom expandable assemblies have a distal portion in communication with a surface of the distal cage and a proximal portion in communication with a surface of the proximal cage. The expandable implant is expandable firstly in a medial-lateral direction, secondly in a lordotic (e.g., angular) direction, and thirdly a cranial-caudal direction. Additionally, the expandable implant may be diagonally symmetrical about a longitudinal axis of the expandable implant.

A method of forming a composite titanium body for use in forming spinal implant interbodies includes selecting a metal alloy body, carving out a top portion and a bottom portion from the metal alloy body, and bonding a porous material to the carved-out top and bottom portions. Multiple pieces may be cut from the composite titanium body, each having a front face formed of the metal alloy, top and bottom portions formed of the porous material, and with a medial portion of the metal alloy extending from the front face to the back. Methods and devices for spinal interbodies having locking mechanisms to prevent bone screw back-out are also described.

In various aspects, an implant includes a body having a lattice structure, with the lattice structure extending continuously from a superior surface of the body to an inferior surface of the body. The lattice structure may define a gradient of pores, with each pore in the gradient having a plurality of vertices. Additionally, the implant may include a plurality of projections extending superiorly from each of the plurality of vertices of each pore of the gradient of pores at the superior surface of the body, with each projection of the plurality of projections having a directionality. The implant may also include one or more radiographic markers incorporated into the lattice structure, the one or more radiographic markers having a density greater than the density of the lattice structure immediately around the one or more radiographic markers and being comprised of the same material as the lattice structure.

Disclosed rod reduction systems include an elongated housing having a longitudinal bore and a transverse channel extending through the elongated housing at a non-zero degree angle relative to the longitudinal bore. An insert is slidable within the transverse channel between an outwardly displaced position and an inwardly biased position. The insert includes a threaded portion and a longitudinal bore alignable with the longitudinal bore of the elongated housing. A reducer is slidably receivable within the longitudinal bore of the elongated housing. The reducer may have a longitudinal bore therethrough, and a drive shaft positioned within the longitudinal bore of the reducer.

An osteogenic composition comprises growth-factor augmented cortical bone and cancellous bone having viable endogenous osteogenic cells that remain adherent to the cancellous bone. The growth-factor augmented cortical bone comprises demineralized cortical bone amplified with growth factors derived from a demineralized bone, and the cancellous bone not having been subjected to a loosening agent. The osteogenic composition is cryopreserved or lyopreserved. A method for preparing an enhanced graft composition with improved osteoinductive properties includes processing demineralized cortical bone; solubilizing growth factors from demineralized bone; and mixing the demineralized cortical bone with the solubilized growth factors.
