Abstract:
1. An attachment member for an orthopaedic device for realigning bone segments, the attachment member comprising: a clamp to attach to a rib bone, a lamina, or a transverse process of a vertebra, the clamp including an upper arm, a lower arm, and a hinge; and a screw inserted into an opening in the clamp, the screw including a screw head and a longitudinal axis that extends along a length of the screw, the screw configured to, upon tightening, advance through the opening in the clamp, to fix into the rib bone, the lamina, or the transverse process to prevent rotational movement or sliding of the clamp along the rib bone, the lamina, or the transverse process, wherein the upper arm includes a first shoulder having a first prominence and wherein the lower arm includes a second shoulder having a second prominence, the first prominence and the second prominence being positioned adjacent to the hinge such that as the screw is tightened to advance through the opening in the clamp to fix into the rib bone, the lamina, or the transverse process, the screw head pushes against the first prominence and the second prominence to force the upper and lower arms to pivot about the hinge to a clamped position, wherein the clamp includes a first clamp and the attachment member further comprises: a second clamp to attach to a second rib bone, a second lamina, or a second transverse process of a second vertebra, the second clamp including a second clamp upper arm, a second clamp lower arm, and a second clamp hinge, the second clamp upper arm and the second clamp lower arm including a third clamp shoulder and a fourth clamp should respectively, the third clamp shoulder and the further clamp shoulder including a third prominence and a fourth prominence respectively, the third prominence and the fourth prominence being positioned adjacent to the hinge; a second screw inserted into a second clamp opening in the second clamp, the second screw including a second screw head, a second longitudinal axis that extends along a length of the seconds screw, the second screw configured to, upon tightening, advance through the second clamp opening in the second clamp, to fix into the second rib bone, the second lamina, or the second transverse process to prevent rotational movement or sliding of the second clamp along the second rib bone, the second lamina, or the second transverse process; and a spacer member coupled to the first clamp and the second clamp.
