IIB 期平足病征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研究

联合采用跟骨质內移截骨质、前端四角该线的移植手术技术是治疗法 IIB 期平脚症的中用方法。如何不致前脚外展病症主因外科移植手术，终于借助概念化治疗法和冗余治果。本文就此问题展开深入研究，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 年代起，有创作者提出联合采用跟骨质內移截骨质、前端四角该线以及骨骼移植手术技术治疗法 IIB 期平脚症。近期，更为多的文献提出了直接外科移植手术某种特定病症所需要的矫形标准。

•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 期平脚的移植手术方法。愈来愈最主要的是发表意见了术前具体跟骨质內移截骨质的对齐素质和前端四角该线中不致前脚外展病症主因外科移植手术仅次于素质的方法，终于借助概念化治疗法和冗余治果。

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 跟骨质內移截骨质

Koutsgiann, medial displacement 1/3-1/2

•LCL 前端四角该线

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)

跟骨质內移截骨质可以降低外侧纵弓的应力，內移跟腱止点，但难得的內移素质尚未具体。均的尸首生物力学实验表示同意內移 10 mm.

•LCL

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

前端四角该线移植手术可以外科移植手术前脚的外展病症，同时可以外科移植手术达 60% 的后脚外翻病症

参考文献 ：

•LCL overcorrection will lead to

lateral column rigidity stress fracture of 5th metatarsal

但前端四角该线主因可能导致脚前端纵弓的麻木，第 5 跖骨质应力主因密集后的病理性骨质折。

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