Segmental orthopedic device for spinal elongation and for treatment of scoliosis

摘要

An orthopaedic device to realign bone segments comprises first and second attachment members and a strut or spacer member. The first attachment member is attached to a first rib bone or first transverse process or first lamina of a vertebra. The second attachment member is attached to a second rib bone or second transverse process or second lamina of a vertebra. The strut is positioned between the first and second attachment members. The strut is fixedly or releasably connected to the first and second attachment members to couple the first attachment member to the second attachment member. The strut provides distraction between the first and second rib bones or transverse processes to realign the rib bones. The attachment members comprise a clamp and screw combination.

1. An orthopaedic device for realigning bone segments, comprising:
a first attachment member, the first attachment member including:
a clamp configured to attach to at least one of a rib bone, a transverse process, and lamina of a vertebra, the clamp including an upper arm, a lower arm, and a hinge; anda screw configured to be inserted into an opening in the clamp, the screw including a screw head, wherein the screw has a longitudinal axis that extends along a length of the screw and wherein the screw is configured to fix into the at least one of the rib bone, the transverse process, and the lamina of the vertebra to prevent rotational movement or sliding of the clamp along the at least one of the rib bone, the transverse process and the lamina of the vertebra; anda projection between shoulders of the clamp and the screw head, the projection including a second opening positioned in the projection that is configured to receive a spacer member to connect the first attachment member to a second attachment member and that is configured to retain the spacer in a direction substantially orthogonal to the longitudinal axis from the first attachment member to the second attachment member, the second opening extending from a first side of the projection to a second side of the projection in the direction substantially orthogonal to the longitudinal axis.
