SACRAL OR ILIAC CROSS CONNECTOR

摘要

Implantable devices and methods for correcting spinal deformities or degeneration are disclosed. The devices and methods have particular application in the spinopelvic region and on the sacrum or ilium. In one embodiment, a cross connector is provided and can include a cross member with a connector head slidably disposed thereon. The cross member can be adapted for attachment to one or more anchoring elements, and the sliding connector head can include a first receiving portion defined by an opening through the connector head for receiving the cross member, and a second receiving portion defined by a recess between first and second opposed arms for receiving a spinal fixation element, such as a spinal rod. A guide channel can optionally be provided on the cross member for guiding the movement of the sliding connector head. In other embodiments, the device can include a locking mechanism for locking a spinal fixation element within the connector head, and for securing the connector head in place on the cross member.
