Software-guided realignment is proposed as an easy and accurate method of achieving simultaneous multiaxial correction. The accuracy and efficacy in periarticular problems have not been investigated fully. This study investigates the results and possible clinical benefits.
A retrospective review was performed in 24 patients with 27 periarticular deformities of the lower limb treated by the Ilizarov technique. Bony realignment was achieved by a software-guided hexapod realignment device. The deformity category, deformity severity score (DSS) and individual deformity component scores were measured for objective quantification of each deformity. The periarticular level, number of manoeuvres, correction period and any difficulties in the execution of the correction manoeuvre were noted. Pre-procedure and post-procedure values of deformity parameters were analysed to estimate the accuracy and efficacy of the realignment device.
The correction manoeuvre was accomplished successfully in all patients except two. The mean correction period was 14.9 days (range, 5-38 days). The mean pre-procedure DSS was 18.7 (range 6.3-27.3), which reduced to a mean post-procedure value of 1.5 (range, 0-7.9) with a 92.0% deformity correction (-value < 0.001)). There was a significant reversal of individual deformity components. DSS values were achieved to an excellent level (< 3.5) in 25 deformities and to good and poor levels in one deformity, respectively.
Software-guided realignments are effective for accurate realignment of periarticular deformities using Ilizarov fixators. These devices offer simultaneous multidimensional corrections even in complex multiplanar deformities and simplify the task of deformity correction.
The present study assesses the accuracy and efficacy of software-guided realignments using novel concepts of deformity category, DSS and individual deformity component scores, which may overcome some of the shortcomings of conventional assessment methods.

软件引导下的重新定位被认为是一种实现同步多轴矫正的简便且准确的方法。其在关节周围问题中的准确性和有效性尚未得到充分研究。本研究旨在探究其结果及可能的临床益处。
对24例采用伊里扎洛夫技术治疗下肢27处关节周围畸形的患者进行回顾性研究。通过软件引导的六足矫正装置实现骨的重新定位。测量畸形类别、畸形严重程度评分（DSS）及各个畸形组成部分的评分，以客观量化每种畸形。记录关节周围水平、操作次数、矫正期以及矫正操作执行过程中遇到的任何困难。分析术前和术后畸形参数值，以评估重新定位装置的准确性和有效性。
除2例患者外，所有患者的矫正操作均成功完成。平均矫正期为14.9天（范围5 - 38天）。术前平均DSS为18.7（范围6.3 - 27.3），术后平均降至1.5（范围0 - 7.9），畸形矫正率达92.0%（P值<0.001）。各个畸形组成部分有显著改善。25处畸形的DSS值达到优秀水平（<3.5），1处畸形达到良好和较差水平。
软件引导下的重新定位对于使用伊里扎洛夫固定器准确矫正关节周围畸形是有效的。这些装置即使在复杂的多平面畸形中也能提供同步的多维度矫正，并简化了畸形矫正任务。
本研究使用畸形类别、DSS及各个畸形组成部分评分等新概念评估软件引导下重新定位的准确性和有效性，可能克服传统评估方法的一些缺点。
