DEVICE AND METHOD FOR SIMULTANEOUS BILATERAL PELVIC OSTEOTOMIES

摘要

A method and device facilitates the procedure of a transverse osteotomy of both ilium and a secondary osteotomy through the pelvic symphysis. A plate (40) is utilized which has facility for attachment of eight screws into the animal bone tissue to more securely hold the plate (40) in place. The shape of the plate (40) represents a significant advance and has important characteristics, including (1) only one side of the plate (40) has sharply angled surfaces to accommodate rotated pelvic bone portions, the other side of the plate (40) is smoothly continuous and facilitates a more stable direct insertion of the bone screws to prevent non-even pressure from being applied to the bores (55) provided for insertion of the bone screws; (2) in this configuration, the bores (55) can closely match the shapes of the heads of the bone screws and provide less exposed material at the outside of the plate (40), as well as providing entry of bone screws at right angles to the bone tissue adjacent the sharply angled surfaces; (3) the plate (40) provides the ability for it to be bent and, more than ample material is provided to bend the plate (40) along its axis to provide an even more enhanced ability to insert bone screws at right angles to the extent of the pelvic bone tissue and to avoid an angle which would prevent secure bone attachment of the bone screws and maximum surface area contact and support from the sharply angled surfaces directly onto bone tissue.
