距骨其表面大約被60%--70%關節(jié)軟骨覆蓋,,是全身唯一無肌肉附著的骨骼,,本身沒有獨立的供養(yǎng)血管,僅通過增厚的韌帶與關節(jié)囊分布供應其血運,,由于這些解剖特征,,距骨骨折后缺血壞死、創(chuàng)傷性關節(jié)炎是其主要并發(fā)癥,,距骨骨折,、脫位需要切開復位時,手術入路會造成距骨血運的破壞,,結(jié)果造成距骨缺血壞死,,所以我們在選擇手術入路時不僅要根據(jù)骨折類型、固定方式,,更應該選擇合適的手術入路,,避免因手術操作本身所造成的距骨血供的損害,采用踝關節(jié)前內(nèi)側(cè)入路治療距骨頸,、體部骨折,,有效地保護了距骨損傷后未遭破壞的主要供血動脈,避免了因常規(guī)的手術入路所致的供血動脈損傷的可能性。通過選擇踝關節(jié)前內(nèi)側(cè)入路手術治療距骨骨折,,進一步指導和驗證此入路治療距骨骨折降低了骨折后缺血性壞死率,,療效確切,降低距骨骨折后缺血壞死等并發(fā)癥,,今天早讀就為大家分享經(jīng)踝關節(jié)前內(nèi)側(cè)入路治療距骨骨折,,值得大家學習參考!
