To　study　the　anatomical　measurement　of　goat　lumbar　vertebrae　and　to　compare　with　human　lumbar　vertebrae,　so　as　to　build　the　foundation　for　establishing　animal　models　of　lumbar　prosthesis.The　anatomical　parameters　of　the　vertebral　body,　pedicle　and　intervertebral　disc　in　the　fresh　lumbar　vertebrae　of　Boer　goat　and　the　lumbar　vertebrae　of　healthy　adults　were　collected　by　computer　aided　software　Mimics16.0,　and　the　anatomical　characteristics　of　the　two　lumbar　vertebrae　were　compared　with　the　statistical　software.The　anterior　vertebral　body　height(VBHa)　of　goat　lumbar　was　less　than　the　middle　vertebral　body　height(VBHm),　which　was　less　than　the　posterior　vertebral　body　height(VBHp),　and　the　maximum　values　were　(38.7±2.9),　(40.1±2.6)　and　(40.7±2.7)　mm　respectively.　Its　endplate　width　was　greater　than　its　depth,　with　the　whole　shaped　like　a　heart　or　a　kidney.　The　cranial　endplate　of　goats　was　convex　while　the　caudal　endplate　was　depressed　and　the　depression　was　small,　with　a　maximum　value　of　(1.6±0.6)　mm.　The　pedicle　height　of　goats　increased　from　L₁1　to　L̀　with　the　maximum　of　(30.5±1.9)　mm;　its　pedicle　width　and　angle　increased　firstly　and　then　decreased　with　the　increase　of　vertebra　level　and　the　minimum　values　were　(6.7±0.4)　mm　and(45.9±2.6)°　respectively.　The　anterior　intervertebral　disc　height　was　larger　than　the　middle　which　was　larger　than　the　posterior　and　all　varied　slightly　with　the　changes　of　intervertebral　spaces;　the　height　and　width　of　intervertebral　foramen　separately　waved　at　(12.9±0.3)　to　(14.3±1.0)　mm　and　(5.7±1.0)　to　(6.7±0.9)　mm.　The　comparative　results　showed　that　the　vertebral　body　height,　pedicle　height　and　angle　of　goats　were　greater　than　those　of　humans　(＜i＞P＜/i＞＜0.05)　while　the　width　and　depth　of　the　endplate,　the　intervertebral　disc　height,　and　etc.　were　significantly　smaller　than　those　of　humans　(＜i＞P＜/i＞＜0.05).　In　addition,　some　structures,　such　as　the　height　of　pedicle　and　intervertebral　disc,　also　showed　different　changing　laws　with　the　increase　of　vertebra　level.Although　there　are　similarities　in　goat　lumbar　spine　in　some　aspects,　such　as　endplate　and　foramen　foramen,　there　are　still　many　differences　in　many　aspects.　Understanding　the　anatomical　characteristics　of　goat　lumbar　vertebrae　and　the　difference　between　goat　and　human　is　of　great　guiding　significance　for　the　research　of　goat　prosthesis　and　related　technology.
