Spinal column retaining method and apparatus
Abstract
Abstract A method and apparatus is provided to retain elements (16) of the spine and/or pelvis in a desired spatial relationship. A plurality of fasteners (20) are connected with a plurality of the elements. A longitudinal member (26) is connected with the fasteners by a plurality of connector members (32). The longitudinal member and fasteners are movable relative to each other to adjust the distance between the longitudinal member and fasteners to thereby obtain the desired spatial relationship between the longitudinal member and elements to which the fasteners are connected. Once the longitudinal member and fasteners have been positioned in the desired spatial relationship, clamps (44, 50) are engaged to hold the longitudinal member, fasteners and connector members against relative movement. To provide for the adjustability of the longitudinal member relative to the fasteners, oblong openings (38) are formed in the connector members. In one specific method of adjusting the position of the longitudinal member relative to the fasteners, the longitudinal member is rotated about an axis which extends through a portion of the longitudinal member. <IMAGE>
