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

A system and a method for performing a spinal procedure configured to minimize the size of the surgical corridor so as to reduce recovery time is provided. The system and method include an implant and a guide. The guide is configured to be disposed within a surgical corridor formed by an instrument. The instrument is removed wherein the muscles may contract onto the guide so as to reduce the surgical corridor, wherein the implant is slid down the surgical corridor between a pair of guide members.

Implants and guides for inserting an implant

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.

Systems and methods for securely assembling a spinal implant

A system for spinal fusion includes a spacer, a plate, an attachment member, and a first temporary fixation screw. The spacer includes a first coupling aperture having a first thread with a thread pitch that is greater than or equal to one third of a depth of the first coupling aperture. The plate includes a first attachment aperture and second coupling aperture. The attachment member includes a mating thread that mates with the first thread. The attachment member is configured to couple the spacer and the plate when inserted through the second coupling aperture and rotated to engage the first thread of the first coupling aperture. The first temporary fixation screw is configured to attach the plate to a first vertebra when inserted through the first attachment aperture and driven into the first vertebra.

Spacer with temporary fixation plate

An instrument for correction of spinal deformities includes an inner member with a proximal portion configured to receive a corrective force and a distal coupling portion configured to transfer the corrective force to a spinal implant in a vertebra. A slot extends transversely through the coupling portion and is configured to guide a fixation rod into the spinal implant. A threaded sleeve includes an external thread and a thru-bore that slides relative to the proximal portion. An outer member couples with the proximal portion and threadably engages the external thread to apply a reduction force as the outer member rotates relative to the inner member. A reduction blade includes a proximal interlocking portion that removably couples with the threaded sleeve and a distal rod engagement feature configured to engage the fixation rod and transfer the reduction force to reduce the fixation rod into the spinal implant.

Spinal deformity correction instruments and methods

A bone fixation plate includes a first opening formed in a plate that is configured to receive a first fastener; a second opening formed in the plate that is configured to receives a second fastener, and a retention member that extends into a third opening formed in the plate between the first opening and the second opening, wherein the retention member is elastically deformable between at least three positions.
