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程度的文献资料研究

牵头用到跟骨內移截骨、侧边拱形该线的切除术核心技术是疗程 IIB 期平足病患者的特指新方法。如何尽量避免前足外展脊拱形所致调适，再次借助源泉疗程和提高效率治果。本文先前问题揭开序幕研究，仅供大家参考！

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 世纪末起，有作者重申牵头用到跟骨內移截骨、侧边拱形该线以及腹腔切除术核心技术疗程 IIB 期平足病患者。持续发展，日益多的文献资料重申了有效调适某种特定脊拱形所需的牙科标准。

•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.

本文之前，作者讲解了其疗程 IIB 期平足的切除术新方法。更是重要的是发表意见了术前确定跟骨內移截骨的移位素质和侧边拱形该线之前尽量避免前足外展脊拱形所致调适最大素质的新方法，再次借助源泉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.

同时作者也发表意见了疗程 IIB 期平足之前短期和长期的并发病患者情况

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 侧边拱形该线

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)

跟骨內移截骨可以减小下侧纵弓的外力，內移跟腱止点，但期望的內移素质尚未确定。仅有的尸骸细胞学实验促请內移 10 mm.

•LCL

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

侧边拱形该线切除术可以调适前足的外展脊拱形，同时可以调适大约 60% 的后足外翻脊拱形

参考资料 ：

•LCL overcorrection will lead to

lateral column rigidity stress fracture of 5th metatarsal

但侧边拱形该线所致意味著所致足侧边纵弓的僵硬，第 5 跖骨外力所致集之前后的病理性骨折。

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

如何通过不合理的脊拱形调适来保证情愿的治果呢？
