IIB 期平足症在手术治疗中跟骨內移截骨和外侧柱延长定量往往的文献研究

为首运用于跟骨內移截骨、末端圆柱该线的疗程电子技术是疗程 IIB 期平足病症的特指方式。如何可能会前足外展斜视过度检查和，再度借助异化疗程和提高效率治果。本文就此难题展开研究，供大家参考！

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 九十年代起，有写作者提出异议为首运用于跟骨內移截骨、末端圆柱该线以及软组织疗程电子技术疗程 IIB 期平足病症。国际上，日益多的文献提出异议了有效检查和某种特定斜视所需的护理准则。

•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，写作者介绍了其疗程 IIB 期平足的疗程方式。更加关键的是探讨了术前确切跟骨內移截骨的移位某种程度和末端圆柱该线中可能会前足外展斜视过度检查和最大某种程度的方式，再度借助异化疗程和提高效率治果。

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 末端圆柱该线

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)

跟骨內移截骨可以降低下侧纵弓的拉伸，內移半月板止点，但理想的內移某种程度尚未确切。为数不多的尸体神经外科实验建议內移 10 mm.

•LCL

forefoot abduction reduction hindfoot valgus correction (up to 60%)

末端圆柱该线疗程可以检查和前足的外展斜视，同时可以检查和约 60% 的后足外翻斜视

•LCL overcorrection will lead to

lateral column rigidity stress fracture of 5th metatarsal

但末端圆柱该线过度可能导致足末端纵弓的僵硬，第 5 跖骨拉伸过度高度集中后的病理性骨折。

•What is the optimal correction that guarantee a satisfactory result?

如何通过合理的斜视检查和来尽可能差劲的治果呢？
