A dynamic intervertebral spacer includes a ring which is split on an anterior portion. A posterior portion of the ring acts as a torsion spring. After implantation, the ring is able to act as a spring between superior and inferior vertebral bodies, thus allowing dynamic bone growth in fusion procedures.

A packaging insert/cartridge for use with an implant having first and second components is provided. The packaging insert includes a main body, a snap fit latch extending proximally from the main body and a spacer extending distally from the main body and configured to be disposed between the first and second components of the implant. The snap fit latch is adapted to snap fit over a mating part of an implant inserter.

A bone fusing implant device includes an elongated body extending along a longitudinal direction and having a star-shaped cross-section. The elongated body includes a central through-opening extending through the elongated body's center along the longitudinal direction and an outer surface with alternating elongated ridges and slit openings extending along the longitudinal direction. The outer surface is coated with bone growth enhancing additives.

An implant insertion tool includes an outer shaft, an inner shaft received in the outer shaft, and two arms coupled to the outer shaft and the inner shaft. The inner shaft translates within the outer shaft and has angled ramps that slide within complementary angled ramps in the two arms. The arms engage an implant for insertion into a body. When the inner shaft translates along a longitudinal axis, it causes the angled ramps to slide against the complementary angled ramps in the arms such that the two arms move laterally relative to the longitudinal axis of the outer shaft to engage and disengage the implant.

In some embodiments, the present disclosure relates to a system that includes an insertion tool and a drill guide. The insertion tool includes a body with a distal portion and a distal end. The body has a first engagement feature extending longitudinally along the distal portion and two arms extending longitudinally from the distal end of the body. The drill guide includes two bores and an open faced channel therebetween. The open faced channel includes a second engagement feature slidably engageable with the first engagement feature on the body of the insertion tool. The two bores are adapted for the disposal of a fastener driver tool therethrough.

An intervertebral implant includes a body and a plate. The body has an upper surface defining an upper plane and a lower surface defining a lower plane. First and second fastener holes of the plate are configured to retain the heads of first and second fasteners. A portion of each of the shanks of the first and second fasteners extends from the first and second fastener holes beyond the upper plane. The shank portions of the first and second fasteners are curved in a direction away from the upper surface. The third fastener hole is configured to retain the head of the third fastener between the upper and lower planes. A portion of the shank of the third fastener extends from the third fastener hole beyond the lower plane. The shank portion of the third fastener is curved in a direction away from the lower surface.
