摘要：
A connecting device for a fibula truncation point, which is used for connecting a first and a second section fibula of a truncated fibula, comprising a nail body having at least one first penetrating segment for axially penetrating into the medullary cavity of the first section fibula of the truncated fibula a first fixation element fixed to the nail body for being across disposed an end surface of the first section fibula or being spaced from the end surface of the first section fibula at a distance and a second fixation element fixed to the nail body for being across disposed on an end surface of the second section fibula or being spaced from the end surface of the second section fibula at a distance as a result, the truncated fibula can be axially connected satisfactorily through propping up the first fixation element and the second fixation element between the end surface of the first and the second section fibula. In addition to preventing the truncated fibula from shifting outwards, when the fibula bears the body weight, the load is transferred axially along the medullary cavity of the fibula, significantly reducing flexural moment and obtaining good axial support to effectively avoid another fracture of the fibula. Alternatively, settlement of the truncated fibula is handled by makinbg the first or the second fixation element spaced from the corresponding end surface of the first and second section fibula at a distance.一種腓骨截斷處之銜接裝置,係用以銜接被截斷腓骨的第一、二節腓骨,係包括:一釘體,至少含有第一穿入段,用以軸向穿入被截斷腓骨之第一節腓骨的髓腔中;第一固定元件,固定於該釘體上,用以跨置於該第一節腓骨的端面或與該第一節腓骨的端面間隔一間距;以及第二固定元件,固定於該釘體上,用以跨置於該第二節腓骨的端面或與該第二節腓骨的端面間隔一間距;如是藉由該第一、二固定元件頂撐在該第一、二節腓骨端面間,使被截斷的腓骨可以獲得良好的軸向銜接,除了防止受截斷的腓骨向外側偏移外,當腓骨受自體重量時,承載沿腓骨髓腔軸向傳遞,可大量減少彎曲力矩,並可獲得良好的軸向支撐,有效避免腓骨再度發生骨折現象,或藉由該第一固定元件或第二固定元件與對應的第一、二節腓骨端面間相隔一間距,以因應被截斷萉骨的沉降。(F1)‧‧‧第一節腓骨(F11)‧‧‧髓腔(F2)‧‧‧第二節腓骨(F21)‧‧‧髓腔(10)‧‧‧釘體(11)‧‧‧第一穿入段(12)‧‧‧第二穿入段(20)‧‧‧第一固定元件(30)‧‧‧第二固定元件(M)‧‧‧內側(L)‧‧‧外側(T)‧‧‧脛骨
