建立联系使用跟骨內移截骨、下方木柱延展的疗程关键技术是治疗法 IIB 期平足综合症的类似于方式。如何避免前足外展脊木柱所致外科手术，再一实现概念化治疗法和优化治果。本文早已问题展开研究成果，亦可大家参考！
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，有创作者设想建立联系使用跟骨內移截骨、下方木柱延展以及软组织疗程关键技术治疗法 IIB 期平足综合症。近年来，越来越多的文献设想了适当外科手术某种特定脊木柱所需的矫形标准。
•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，创作者简介了其治疗法 IIB 期平足的疗程方式。不够最主要的是争辩了术前具体跟骨內移截骨的重新排列程度和下方木柱延展中避免前足外展脊木柱所致外科手术最大程度的方式，再一实现概念化治疗法和优化治果。
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.

Background introduction
•The definition of Stage IIB Flatfoot
talar head uncoverage> 30%
•MCO 跟骨內移截骨
Koutsgiann, medial displacement 1/3-1/2
•LCL 下方木柱延展
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)
跟骨內移截骨可以减小内侧纵弓的脆性，內移跟腱止点，但理想的內移程度早已具体。仅有的尸首细胞学测试决定內移 10 mm.
•LCL
forefoot abduction reduction hindfoot valgus correction (up to 60%)
下方木柱延展疗程可以外科手术前足的外展脊木柱，同时可以外科手术约 60% 的后足撕裂脊木柱
参考文献 ：
•LCL overcorrection will lead to
lateral column rigidity stress fracture of 5th metatarsal
但下方木柱延展所致有可能导致足下方纵弓的僵硬，第 5 跖骨脆性所致高度集中后的病理性骨折。
•What is the optimal correction that guarantee a satisfactory result?
如何通过恰当的脊木柱外科手术来保证满意的治果呢？
