Calcaneal osteotomies are a common procedure in foot and ankle surgery for the treatment of the painful flexible Progressive Collapsing Foot Deformity (PCFD). The lateral calcaneal lengthening osteotomy (LCLOT) allows a three-dimensional foot and ankle flatfoot correction with a single osteotomy. The purpose of this article is to review the types of calcaneal lengthening osteotomies. Review of anatomical, biomechanical and clinical studies and reviews. The LCLOT shall be differentiated from the Evans osteotomy or Z-shaped calcaneal lengthening osteotomy. The LCLOT is performed at the sinus tarsi and corrects at the subtalar joint axis biomechanically the pathological hindfoot valgus, foot abduction, and medial arch collapse. The LCLOT technique might vary regarding graft and fixation type. The LCLOT has good clinical results with high union rates. The LCLOT is a powerful and successful single-site osteotomy for the triplanar correction of the painful flexible flatfoot/PCFD.
跟骨截骨术是足踝外科治疗疼痛性柔韧性进行性塌陷性足畸形（PCFD）的常见手术。外侧跟骨延长截骨术（LCLOT）通过单次截骨可实现足踝三维扁平足矫正。本文旨在综述跟骨延长截骨术的类型。回顾解剖学、生物力学和临床研究及综述。LCLOT应与伊文斯截骨术或Z形跟骨延长截骨术相区分。LCLOT在跗骨窦进行，在距下关节轴处通过生物力学方式纠正病理性后足外翻、足外展和内侧足弓塌陷。LCLOT技术在植骨和固定类型方面可能有所不同。LCLOT临床效果良好，愈合率高。LCLOT是一种用于疼痛性柔韧性扁平足/PCFD三平面矫正的有效且成功的单部位截骨术。
