A system and a bone fixation plate for preventing a fastener from rotating so as to prevent the fastener from backing out is provided. The system includes a plate having an opening. A retention member having an arm extending into the opening is configured to engage the head of the fastener so as to prevent the fastener from rotating after the fastener is seated within a vertebral body or implant. In one embodiment, the retention member engages a top surface of the head of the fastener. In another embodiment, the retention member engages a side wall of the head of the fastener.

Bone fixation systems and methods

An instrument and inserter kit for providing a load to insert or retract an implantis provided. The instrument includes a cover having an engagement end opposite a distal end. The engagement end is configured to mount to an engagement feature of a handle of an inserter. The cover is an elongated member having a C-shaped profile having a dimension configured to receive a sliding member. The sliding member is seated over the cover and is weighted. The sliding member is configured to slide between a first radial lip and a second radial lip so as to provide an impacting force or retracting force on the instrument.

Instrument configured to generate an impact and retracting load on an inserter

Systems and methods for implanting a spinal implant between two vertebral bodies are provided. The spinal implant may include a main body adapted to rest between and adjacent to the two vertebral bodies, the main body having a cavity therein adapted to hold a filler and a cap adapted to connect to the main body where the cap is connectable after the main body has been inserted between the vertebral bodies and after the filler has been inserted into the cavity of the main body. The cap is securable to the main body by means of a securement member providing for a permanent connection between the main body and the cap.
