    摘要: An adjustable connector including first and second connector members rotationally coupled together and configured to receive first and second spinal rods, respectively. In one embodiment, the first connector member includes an elongated slot that receives the first rod and has a length extending along an axis arranged transverse to the rotational axis, and the second connector member includes a second passage that receives the second rod. A lock member is positioned between the connector members and includes an angled rod bearing surface extending along a plane oriented at an oblique angle relative to the rotational axis. A compression member extends into the first passage of the first connector member and into compressed engagement with the first rod to displace the first rod along the length of the elongated slot and into sliding engagement with the angled rod bearing surface, which in turn axially displaces the lock member toward the second connector member to compress the first interface surface of the lock member against an opposing second interface surface to selectively prevent relative rotation between the connector members.

    摘要: A side-loading bone anchor is provided, which may be used in cervical, thoracic, lumbar or sacral areas of the spine or other orthopedic locations. In one embodiment, the anchor includes an anchoring portion, a receiving portion, and an internal piece that is rotatable with respect to the receiving portion at least to a degree. The anchoring portion is attached to a bone. A rod or other elongated support member is received in the receiving portion in contact with the internal piece. The rod and internal piece may be rotated for variability substantially in a plane, and a set screw is threaded into the receiving portion to lock the rod within the receiving portion.
