External　fixators　are　widely　used　in　orthopedics　for　the　purposes　of　fracture　reduction　and　bone　deformity　correction.　Since　there　is　nonlinear　mapping　between　the　joint　and　operation　spaces　of　the　external　fixator,　bone　correction　trajectories　achieved　by　equally　adjusting　the　length　of　the　struts　in　the　joint　space　are　usually　not　the　trajectories　that　clinicians　expect.　Based　on　two　different　adjustment　strategies,　a　new　strategy　considering　bone　end-plane　orientation　and　the　shortest　growth　path　is　proposed　to　plan　the　position　and　orientation　of　the　distal　bone　end,　which　is　named　joint　adjustment　for　equal　bone　distraction.　By　proposing　the　inverse　and　forward　kinematic　solutions　of　an　Ortho-SUV　external　fixator,　correction　trajectories　with　three　different　adjustment　strategies　are　generated　and　compared,　and　the　bone　shapes　for　each　strategy　are　modeled.　The　results　obtained　by　comparative　analysis　indicate　that　a　smooth　and　uniformly　spaced　linear　trajectory　can　be　acquired　using　the　new　adjustment　strategy,　which　can　avoid　bone　end　interference　and　maintain　an　optimal　distraction　rate　of　1.03mm/day,　with　only　a　3%　error　compared　with　1mm/day.　The　new　strategy　can　perform　multiplane　corrections　simultaneously　and　is　beneficial　for　stimulating　the　growth　of　new　bone　tissue.
