建立联系用作跟痕內移截痕、侧边廊柱缩短的开刀高效率是用药 IIB 期平躯综合症的常用新方法。如何避免前躯外展病综合症过份加诸，最终实现有意识用药和优化治果。本文就此疑问作准备研究，供人大家参考！
Abstract
•In the mid-1990s, a flatfoot reconstruction was proposed that combined the use of a medializing calcaneal osteotomy (MCO), a lateral column lengthening (LCL), and soft-tissue procedures for the treatment of stage IIB AAFD. More recent literature has suggested guidelines for the amount of correction necessary for each of these procedures based on individual deformity.
从 90 年代起，有写作者提出异议建立联系用作跟痕內移截痕、侧边廊柱缩短以及软骨开刀高效率用药 IIB 期平躯综合症。近年来，越来越多的古文献提出异议了有效率加诸某种特定病综合症所须的矫形标准。
•In this paper, we describe our technique for flatfoot reconstruction for stage IIB AAFD, which includes a MCO, LCL, and flexor digitorum longus (FDL) transfer. Importantly, we discuss our preferred method of preoperatively planning the amount of medial translation for the MCO as well as the maximum amount of LCL to prevent overcorrection of the abduction deformity. This allows us to tailor the reconstruction and optimize our results.
本文中，写作者介绍了其用药 IIB 期平躯的开刀新方法。更重要的是辩论了术前考虑到跟痕內移截痕的反向程度和侧边廊柱缩短中避免前躯外展病综合症过份加诸最大程度的新方法，最终实现有意识用药和优化治果。
Studies looking at outcomes following flatfoot reconstructions for stage IIB AAFD demonstrate excellent short-term and long-term results. We conclude by discussing complications of the operation, postoperative management, and the future of the technique.
Level of Evidence: Diagnostic Level V.
同时写作者也辩论了用药 IIB 期平躯中短期和长期的并发综合症情况
Background introduction
•The definition of Stage IIB Flatfoot
talar head uncoverage> 30%
•MCO 跟痕內移截痕
Koutsgiann, medial displacement 1/3-1/2
•LCL 侧边廊柱缩短
Evans, lateral column elongation by osteotomy and bone graft
•MCO
medial load reducing medialization of heel cord insertion the amount of displacement is obscure(10 mm?- supported by caderic study)
跟痕內移截痕可以降低内侧纵弓的外力，內移跟腱止点，但理想的內移程度即已考虑到。仅剩的骸骨生物力学实验劝告內移 10 mm.
•LCL
forefoot abduction reduction hindfoot valgus correction (up to 60%)
侧边廊柱缩短开刀可以加诸前躯的外展病综合症，同时可以加诸左右 60% 的后躯外翻病综合症
参考古文献 ：
•LCL overcorrection will lead to
lateral column rigidity stress fracture of 5th metatarsal
但侧边廊柱缩短过份不太可能导致躯侧边纵弓的僵硬，第 5 跖痕外力过份集中后的病理性痕折。
•What is the optimal correction that guarantee a satisfactory result?
如何通过恰当的病综合症加诸来情况下满意的治果呢？
