Leprosy or Hansen's disease is a chronic infectious disease caused by the Mycobacterium leprae. Nerve injury is a central feature of the pathogenesis of leprosy that results in autonomic, sensory and motor neuropathy. One of the most common secondary disabilities caused by Hansen's disease is the drop foot and it is found in 2% to 5% of newly-diagnosed leprosy patients. Unlike the clinical picture of traumatic injury of the common peroneal nerve where both of its branches (the deep peroneal nerve and the superficial peroneal nerve) are involved, in leprosy there is the possibility of isolated involvement of the deep peroneal nerve branch, sparing the superficial peroneal branch. The article discusses the advantages of using the peroneus longus tendon transfer to the dorsum of the foot instead of the posterior tibial tendon for the correction of dropfoot in selected cases where the peroneals tendons are intact.
麻风病或汉森病是由麻风分枝杆菌引起的一种慢性传染病。神经损伤是麻风病发病机制的核心特征，可导致自主神经、感觉和运动神经病变。汉森病最常见的继发性残疾之一是足下垂，在新诊断的麻风病患者中，其发生率为2%至5%。与腓总神经创伤性损伤的临床表现不同，后者的两个分支（腓深神经和腓浅神经）均受累，而在麻风病中，腓深神经分支有可能单独受累，而腓浅神经分支不受影响。本文讨论了在腓骨肌腱完整的特定病例中，使用腓骨长肌腱转移至足背而非胫后肌腱来矫正足下垂的优点。
