摘要：
A reconfigurable bone adjustment device includes a first member configured for attachment to a first bone fragment, portion, etc., a second member configured for attachment to a second bone fragment, portion, etc., a drive mechanism configured to move the second member relative to the first member, a threaded rod having a proximal end operatively coupled to the drive mechanism and a distal end operatively coupled to the second member so that rotation of the drive mechanism rotates the threaded rod and moves the second member relative to the first member, and a dynamic segment positioned between the first and second members to enable compression of the second member relative to the first member to stimulate bone growth. The dynamic segment may be a silicone/rubber compressible member or assembly, a metallic spring, a non-metallic shock absorbing material or washer, or the like.
