Connector assemblies, systems, and methods thereof. A modular connector has a first end that clamps to a first rod in an existing construct and a second end having a modular connection point configured to connect a second rod in a new construct such that the new construct can be extended from the existing construct.

Connector assemblies, systems, and methods thereof. A connector has a first end that clamps to a first rod in an existing construct and a second end, connected to the first end, that clamps to a second rod in a new construct such that the new construct can be extended from the existing construct at an adjacent level as the existing construct.

A pivotal bone anchor assembly includes a shank sub-assembly comprising a shank and a coupler, and a receiver sub-assembly comprising a receiver having a bore with a bottom opening and a snap-fit assembly proximate the bottom opening comprising an insert, a retainer ring positioned within an expansion chamber, and a positioner configured to hold the retainer ring in position. The shank sub-assembly is uploaded through the receiver bottom opening such that the positioner is pushed up into a holder chamber and the retainer rings engages a circumferential locking groove of the coupler to secure the shank sub-assembly with the receiver sub-assembly with a snap-fit connection.

Bone anchor assemblies and methods are provided having a multi-component bone anchor that is configured to allow the shank of the bone anchor to be bottom loaded into a receiver member. In one embodiment, a bone anchor assembly is provided having a shank with a distal threaded portion and a proximal head portion, a ball having a spherical exterior surface and a central lumen sized to receive the head portion of the shank, and a clip configured to be engaged between the head portion and the ball such that the clip is effective to lock the ball in engagement with the shank.

Medical devices, systems, and methods related to surgical procedures, such as spinal surgeries. The medical devices, systems, and methods utilize an orthopedic or spinal screw system tower, such as a pedicle screw tower configured to be attachable to, removable from, and re-attachable to a pedicle screw head.

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.

A bone fastener comprises a first member defining an implant cavity and a groove configured for disposal of a band. The first member includes a part disposed with the implant cavity and engages with the band to provisionally fix the part relative to the first member. A second member is configured to penetrate tissue and includes a base that moves the part and engages the band to connect the members. Implants, systems, instruments and methods are disclosed.

A spinal construct includes a fastener configured for attachment with sacral and/or pelvic tissue of a body. A connector includes a mating element engageable with the fastener and includes a receiver. A spinal implant is engageable with the receiver between a capture configuration and a removable configuration. A multi-axial fastener is connected with the spinal implant. Systems, implants, instruments and methods of use are disclosed.

An extender is removed from a spinal implant without using a separate device, and the loss of materials to be discarded is reduced. A head part of a spinal implant includes a base part, which is provided as a portion on a screw part side, and a pair of tab parts, which extend from the base part to an opposite side to the screw part side. The pair of tab parts have a tab part-side engagement part to be engaged by an extender-side engagement part that is formed on the extender. A weak part is formed between the base part and the pair of tab parts, the weak part being configured to be broken by an external force from the extender engaged with the pair of tab parts and separate the pair of tab parts from the base part.

A method for treating a spine includes disposing a body including vertebrae in a lateral orientation relative to a surgical fixed surface configured for supporting the body; creating an incision in tissue of the body along a substantially transverse plane of the body; spacing the tissue adjacent the incision along a sagittal plane of the body to define a surgical pathway to the vertebrae; and delivering at least one implant adjacent the vertebrae via the surgical pathway. Systems and implants are disclosed.
