An expandable trial can include an inferior portion, a superior portion, and a middle expanding portion as well as load cells for monitoring the load on the trial. The trial may also include recesses on its lateral sides to provide spacing to accommodate a disc removal tool so tissue can be cleared monitoring load. In addition, neural foramen spacing can be monitoring to provide information about how much neural release has been achieved as the disc is cleaned and the spine is positioned and repositioned.

Methods and devices for spinal correction

A system for delivering flowable biomaterial to an intervertebral disc space between adjacent vertebral bodies includes a delivery body defining a proximal end, a distal end spaced from the proximal end along a longitudinal direction, a cannulation extending from the proximal end to an opening adjacent the distal end, and a distal region including a tip that extends to the distal end. The distal region defines a maximum height at a location proximal of the distal end and measured along a second direction perpendicular to the longitudinal direction. The distal region is for indicating a distance between the adjacent vertebral bodies. The system includes a carrier having a longitudinally elongate channel for carrying biomaterial and being insertable within the cannulation, as well as an advancement member configured for insertion within the cannulation to forcibly advance the biomaterial from the cannulation, through the opening, and into the disc space.

Biomaterial delivery device, and related systems and methods

A fastener device includes an anchor body that defines a through hole. The anchor body further includes an inner surface that defines a least a portion of the through hole. The fastener includes a head, a threaded shaft that extends out with respect to the head in a distal direction, and a neck between the head and threaded shaft. The head includes an outer surface configured to articulate along the inner surface when the fastener head is inserted in the through hole. At least a portion of the outer surface is convex and defines a portion of a sphere that defines a first diameter. The neck defines a second diameter and the fastener defines a ratio of the first diameter to the second diameter in a range between about 2 to 1 and about 3 to 1.

Polyaxial bone fixation element

Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Multipoint fixation implants

Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member. The distal portion of the wing can define a bone anchor opening through which one or more auxiliary bone anchors can be disposed to augment the fixation of the assembly's primary bone anchor. A distal surface of the distal portion of the wing can be obliquely angled relative to a proximal-distal axis of the spanning portion to face one of a caudal direction or a cephalad direction. A distal surface of the distal portion of the wing can be obliquely angled relative to the proximal-distal axis of the spanning portion to face one of a medial direction or a lateral direction. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Multipoint fixation implants and related methods

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, 'ultra-MIS' techniques.

Multi-shield spinal access system

Access port cutters and related systems and methods can be used to cut an access port to a desired length based on particular patient and/or surgical procedure needs at a point of use. More particularly, an access port cutter can include a base with an opening that can receive an access port therein such that a desired length of the access port can extend from the opening. An actuation mechanism can translate a blade linearly along at least a portion of the base such that the blade can traverse the opening and cut across the access port. In some embodiments, the actuation mechanism can include a handle that can pivot relative to the base to drive the blade. One or more safety features can reduce the risk of inadvertent actuation of the blade and/or prevent debris from contaminating a surgical site or falling onto a patient.

Access port cutters and related methods

Surgical access stabilization devices, systems, and methods are disclosed herein. For example, the devices, systems, and methods disclosed herein can be used during a surgical procedure to selectively establish, stabilize, and maintain a desired trajectory and/or positioning of a surgical access device. An exemplary surgical access stabilization device can include a pad with an adhesive distal facing surface to adhere to an anchor surface, a surgical access device coupled to the pad, and a locking mechanism to selectively lock a position of the surgical access device relative to the pad. In one embodiment, the anchor surface can be the skin of a patient. An exemplary surgical access device stabilization method can include making an incision in a patient at a surgical site, inserting a surgical access device through the incision, adhering a pad to an anchor surface, e.g., the skin of the patient, coupling the surgical access device to the pad, and selectively locking a position of the surgical access device relative to the pad. Other exemplary devices, systems, and methods are also provided.

Skin foundation access portal

Articulating implant connectors and related methods are disclosed herein. Exemplary connectors can include first and second bodies that are rotatable relative to one another about a rotation axis and selectively lockable to resist or prevent such rotation. Each of the bodies can be configured to couple to a rod or other fixation component, and the connector can be used to lock first and second rods together even when the rods are obliquely angled with respect to one another.

Articulating implant connectors and related methods

Bone anchor assemblies and related methods are disclosed herein that can provide for improved fixation of a primary bone anchor. A bone anchor assembly can include a wing with a distal portion that can define a plurality of auxiliary bone anchor openings. Each auxiliary bone anchor opening can receive an auxiliary bone anchor that can augment fixation of a primary bone anchor of the bone anchor assembly. The plurality of auxiliary bone anchor openings can be oriented such that, when the wing is coupled to a primary bone anchor assembly of a vertebral level in a first configuration, at least one auxiliary bone anchor can be driven to extend across a facet plane of the vertebral level and, when coupled in a second configuration, each auxiliary bone anchor received within the wing can be driven to conform to the vertebral level.

Multipoint angled fixation implants for multiple screws and related methods

Bone anchors and surgical instruments (e.g., bone taps, drivers, etc.) are disclosed herein that include integrated guide tips. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. For example, a surgical instrument can include a guide projection configured for insertion through a cannulation formed in a bone anchor when the surgical instrument is coupled to the bone anchor. The surgical instrument can also include various mechanisms for adjusting the position of the guide projection relative to the bone anchor. The guide projection can replace the needle, stylet, and guidewire used in typical insertion procedures. The bone anchor can also include integrated tapping features to eliminate the need for a separate bone tap instrument. Thus, in some embodiments, targeting, tapping, and driving the bone anchor can be performed in a single step.
