Intramedullary orthopaedic devices |
摘要 |
An intramedullary orthopaedic device for interconnecting bone fragments for union comprises an elongate member of plastics material having a relieved structure extending over its length but only partially therearound, each upstanding element being of transverse sizing to afford an interference fit by translation alone into a slightly undersized bone recess, such fit resulting from flexure of the elements without stripping bone material, and the unrelieved area of the member being of non-circular cross-section to inhibit rotation. The member is suitably of rectangular cross-section with sequences of fins having their longitudinal directions across the major side faces, and with the inter-sequence spacing and fin height each exceeding fin thickness.
