Spinal implant with attachment system

摘要

The embodiments of the present disclosure relate to a spinal implant assembly having features to prevent or minimize fixation elements, such as screws, from being dislodged, or from backing out over time and with use. The spinal implant assembly may comprise an implantable body having first apertures for receiving fixation elements. A plate configured to nest against the posterior portion of the implantable body and comprising one or more second apertures can be provided. These second apertures permit access to the head portions of the fixation elements. One or more locking elements are then passed through the second apertures and engage the head portions of the fixation elements. In addition, the plate may comprise an adjustable arm to allow the plate to be used with implantable bodies of different size.

主权项

1. A method of treating a patient's spine comprising:
accessing at least a portion of a patient's spine via a posterior approach; inserting an implantable body between vertebra bodies of the patient's spine, wherein the body comprises an upper surface, a lower surface, an anterior portion, a posterior portion, and one or more first apertures within the posterior portion of the implantable body, each of the one or more first apertures configured for receiving one of a set of fixation elements; inserting one of the set of fixation elements through one of the first apertures and into the surrounding bone tissue to attach the implantable body to the vertebral bodies, wherein each of the fixation elements comprises a head portion with a bored section; placing a plate having one or more second apertures onto the implantable body, the placement being based on alignment of one of the second apertures of the plate over the bored section of the head portion of the inserted fixation element; and inserting a locking element through the one or more second apertures into the head portion of the inserted fixation element.
