    摘要: A bone anchor (100) for attaching a rod (108) to a bone has an anchor member (106) for attachment to the bone and an anchor head (104) having a U-shaped opening for receiving the rod. The bone anchor also includes a locking cap (102) that has a main body (900) and a set screw (1000). Advantageously, in one embodiment the locking cap preferably is designed such that a single tool can be used to lock the locking cap in place on the anchor body preferably with a 90° turn and preferably then drive the set screw to clamp the rod. The locking cap also preferably non-threadingly engages the anchor body. The anchor body preferably has an inclined surface on its top surface which elastically deflects extending tabs on the main body to secure the locking cap to the anchor body. A method of implantation and assembly of the bone anchor are also described.

    摘要: An anchor assembly for use in spinal fixation to interconnect a longitudinal spinal rod, which is integrally formed with a body of the anchor assembly. The anchor assembly includes a bone anchor, a collet, a body portion, a rod portion, and a locking cap. The anchor assembly is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body portion. The anchor assembly enables a surgeon to implant the bone anchor without the body portion to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the rod portion may be inserted into the rod-receiving channel of a second bone fixation element having a rod-receiving channel implanted at a second site and the body portion can be snapped-onto the bone anchor.

    摘要: The present invention is directed a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.

    摘要: A minimally invasive system and method for coupling a spinal rod to a plurality of bone anchors implanted into a plurality of vertebral bodies. A plurality of bottom-loading polyaxial anchor seat assemblies having different vertical heights are chosen to pop over the heads of the implanted bone anchors and a spinal rod is more easily introduced and secured to the bone anchors. The variety of different heights that characterize the plurality of polyaxial anchor seat assemblies allows a surgeon to intraoperatively choose the appropriate offset for a particular spinal level during spinal corrections.
