Spinal USA | Date: 2016-08-17

Bone screw assemblies that can include a screw, housing, snap ring, saddle, set screw, and rod are described herein. The bone screw assemblies can allow for polyaxial or uniplanr movement of the screw relative to the housing. A threaded portion of the screw can be coated with a hydroxyapatite (HA) coating. The screw can have a triple lead thread configuration. The bone screw assembly may be modular.


Devices and methods are provided for surgical retraction with a minimally invasive, maximum access surgical system. The surgical system can include anchor extensions that can be attached to bone screws. The bone screws can be inserted into a pedicle of a vertebral body. A retractor can be attached to anchor extensions connected to adjacent vertebrae on an operational side, and the retractor can be attached to anchor extensions connected to adjacent vertebrae on a contralateral side. The retractor can be used to distract the vertebral disc space between the adjacent vertebrae.

Devices and methods are provided for spinal disc replacement. A plate can be configured to couple to an intervertebral cage disposed in an intervertebral space. The plate can be modular. For example, the plate can have a first receiving portion angled relative to a second receiving portion. The first receiving portion receives a first bone screw or bone blade to engage a first vertebra, and the second receiving portion receives a second bone screw or bone blade to engage a second vertebra. A retention member can be coupled to the plate. The retention member is configured to block first and second bone screws or bone blades from backing out of the plate.

A bone plate screw-blocking system and method that comprises a plate with at least two bone screw receiving holes, blocking elements, bone screws, and a tool capable of simultaneously actuating at least two blocking elements. The plate includes an upper surface and a lower surface with bone screw receiving holes that extend through both surfaces of the plate. The bone screws couple the plate to the bone via the bone screw receiving holes. The blocking elements are movably positioned proximate each bone screw receiving hole. In an initial unblocked position, the blocking elements do not cover the bone screw receiving holes. Upon movement into final blocked positions, the blocking elements cover at least a portion of the bone screw receiving holes and preferably extend over at least a portion of the bone screw during use.

Pedicle screws that can include a pedicle screw body, housing, plurality of clamps, rod, and set screw are disclosed herein. The clamps may be positioned side by side inside the lower portion of the housing. When the rod and set screw are provided in the housing, the set screw applies a force on the rod and the rod engages the plurality of clamps, causing the clamps to frictionally engage a head of the pedicle screw between the clamps.

This invention concerns a vertebral body replacement element to be inserted into an intervertebral space, thus supporting the spinal column of a patient. The vertebral body replacement element has a hollow upper member and a hollow lower member, with the upper member and lower member engaging in a telescopic manner and establishing a cavity between the two members when assembled. Spacers may be inserted in the cavity to lengthen the vertebral body replacement element. The present invention further concerns a system and method for expanding and distracting a vertebral body replacement element into and within the spinal column of a patient.


Devices and methods are provided for assisting in spinal stabilization. An access device is provided that includes an outer sleeve, inner sleeve, spring latch and lock nut. The inner sleeve includes compressible grasping elements. The access device can be coupled to a screw head by sliding the outer sleeve relative to the inner sleeve and compressing the grasping elements. The coupled access device and screw can then be delivered to a target location in a patient. After providing two or more access devices, a rod member can be delivered using a rod insertion device. The rod member can serve as a connection between the two screws, and can provide spinal stabilization. An anti-torque device and a persuading device can be used to help ensure that the rod member is placed and secured in a proper location within a patient.

Pedicle screws that can include a pedicle screw body, housing, plurality of clamps, rod, and set screw are disclosed herein. The clamps may be positioned side by side inside the lower portion of the housing. When the rod and set screw are provided in the housing, the set screw applies a force on the rod and the rod engages the plurality of clamps, causing the clamps to frictionally engage a head of the pedicle screw between the clamps.


Patent
Spinal USA | Date: 2015-11-09

A bone plate, having a bone screw and a rotatable lock for retaining the bone screw in place, includes a retainer element and/or a stop element. The retainer element inhibits the lock from being pushed off of the bone plate, while the stop element limits the rotational range of motion of the lock.


A retractor assembly for defining a working channel to a surgical site for conducting minimally invasive spinal surgery includes a plurality of relatively articulable components. Temporary interconnections are formed between adjacent sidewalls of the components to hold the components in a desired configuration, such as in a closed triangular form. The components are articulable relative to each other for adjusting the working channel or for performing surgical functions.
