The transmetatarsal amputation has been performed for over 40 years as a limb salvage procedure, in diabetic patients with nonhealing ulcerations or nonreconstructible ischemia. It is generally believed that the transmetatarsal amputation provides a better walking extremity than a more proximal amputation and is more energy efficient. A review of the literature reveals little regarding the biomechanics of the "short foot." The authors will review the functions of the myofascial structures in both the normal foot and the transmetatarsal amputation and discuss the influence of mechanics on transmetatarsal amputation lesions.
经跖骨截肢术作为一种保肢手术已实施了40多年，用于治疗患有无法愈合的溃疡或无法重建的缺血的糖尿病患者。人们普遍认为，与更近端的截肢相比，经跖骨截肢能提供更好的行走肢体，且能量效率更高。对文献的回顾显示，关于“短足”生物力学的研究很少。作者将回顾正常足部和经跖骨截肢术中肌筋膜结构的功能，并讨论力学对经跖骨截肢术损伤的影响。
