An implant is provided for use in stabilizing vertebral bodies or bones, comprising a first end (2) and a second end (3,3), a tubular section (4) between the first end (2) and the second end (3) having a longitudinal axis (L), the tubular section (4) being flexible in such a way that it is expandable in a radial direction when a force (F,F) acts in an axial direction which reduces the distance between the first end (2) and the second end (3).本案提供一種植入體,用於穩定椎骨本體或骨骼,包括:第一端(2)和第二端(3,3);管狀段(4),介於第一端(2)和第二端(3)之間,具有縱軸線(L);管狀段(4)具撓性,力量(F,F)在軸向作用時,使其可在徑向膨脹,減少第一端(2)和第二端(3)間之距離。1...植入體2...第一端段3...第二端段4...中間段5...縱條6...長孔7...橫條8...條單位
