Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Multipoint fixation implants

Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member. The distal portion of the wing can define a bone anchor opening through which one or more auxiliary bone anchors can be disposed to augment the fixation of the assembly's primary bone anchor. A distal surface of the distal portion of the wing can be obliquely angled relative to a proximal-distal axis of the spanning portion to face one of a caudal direction or a cephalad direction. A distal surface of the distal portion of the wing can be obliquely angled relative to the proximal-distal axis of the spanning portion to face one of a medial direction or a lateral direction. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Multipoint fixation implants and related methods

A drill guide for use in securing a spinal fixation plate to a spine is provided. In a preferred embodiment, the drill guide generally includes a support member having first and second arms mated thereto. Each arm includes a proximal end and a distal end having at least one barrel coupled thereto and defining a lumen for receiving a tool. One or both arms can be slidably movable along the support member to allow the distance between the arms to be adjusted. In use, the arms can be adjusted to engage a spinal fixation plate and to position the barrels on each arm in alignment with bores formed in the fixation plate. The drill guide can then be used to drill, awl, tap, and insert implants, such as spinal screws, into the vertebral bodies to attach the fixation plate thereto.
