    Abstract: In one embodiment, a method using a computer system determines a length of a rod for use in spine correction surgery. With images of a patient, a segment of the spine requiring correction is identified along with first and second points (434, 436) at the ends of the segment. Then, a first size and a first position of a first circle (412) are determined based on the image such that a portion of the first circle is generally aligned with a curve of the segment. A second circle (702) with a different size and position is similarly determined based on the image. Both the first and second circles pass adjacent to or through the first point and the second point. A length of a portion of the second circle measured between the first and second points is then used to determine a rod length for a post-surgical spinal alignment.

    Abstract: A bone screw comprises a shaft defining a longitudinal axis and a minor diameter. The shaft including a core having an angled surface relative to the axis. The angled surface extending from the minor diameter adjacent a proximal portion of the shaft to a distal portion of the shaft, and a wall disposed about the angled surface. The wall including at least one thread having an external thread form. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

    Abstract: An anchor (100) coupleable to a bone includes a head (102), a shank (104), a first extension (106) and a second extension (108). The head includes a distal head portion and a proximal head portion, where the proximal head portion is open at a proximal end of the head. The shank extends distally from the distal head portion, where the shank including a threaded portion configured to engage the bone. The second extension is opposing the first extension, and the second extension includes a second proximal support (130a) coupled to a second end of a first elongate portion, where a first proximal support (128a) extends transverse to the longitudinal axis, and the first proximal support portion and the second proximal support portion can be separated in a first condition and can be engaged to transfer forces there between in a second.

    Abstract: A polyaxial offset lateral connector (10) includes a body (20), an insert (40), and a connecting shaft (60). The body (20) has a base (22) that defines a receptacle (32) and walls (24) that extend from the base (20) to define a saddle (26). The insert (40) includes a cup (42) and a pin (48) that extends from a bottom surface of the cup (42). The connecting shaft (60) has a connection portion (62) and a neck (64) extending from the connecting shaft (60) to a ball (72). The ball (72) is received within the receptacle (32) of the body (20) and defines a pin passage (38) therethrough. The pin (48) of the insert is received within the pin passage (38) of the ball (72) to prevent translation of the connecting shaft (60) relative to the body (20).

    Abstract: A modular pedicle screw assembly has a multi-part cam lock structure for fixing a threaded shank to a head subassembly. A modular pedicle screw assembly provides capture and release of a spherical end of a threaded shank by a head through rotation of closures radially disposed in an internal chamber of the head. Geometry of the closures cooperate with geometry of the internal chamber, providing a selective cam action between the closures and the internal chamber to increase and decrease size of an opening formed by the closures. Closure rotation produces an open state where the spherical end of the threaded shank can pass through the closures, releasing the spherical end of the threaded shank from the head, and a closed state where the spherical end of the threaded shank cannot pass through the closures thereby capturing the spherical end of the threaded shank in the head.

    Abstract: : 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.
