Abstract

Aim and objective: 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.

Materials and methods: 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.

Results: 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 (p-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.

Conclusion: 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.

Clinical significance: 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.

软件引导下骨性复位治疗下肢关节周围畸形的准确性和有效性。

目的和目的:提出了一种简单、准确的实现同时多轴校正的方法。关节周围问题的准确性和有效性尚未得到充分的研究。本研究调查了结果和可能的临床益处。材料与方法:对采用Ilizarov技术治疗的24例27例下肢关节周围畸形进行回顾性分析。通过软件引导的六足重新定位装置实现骨重新定位。测量畸形类别、畸形严重程度评分(DSS)和个体畸形成分评分，以客观量化每种畸形。记录关节周围水平、矫治次数、矫治周期和矫治过程中出现的困难。分析手术前和手术后的畸形参数值，以估计矫直装置的准确性和有效性。结果:除2例患者外，其余患者均成功矫正。平均校正周期为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DSS为1.5(范围0-7.9)，畸形矫正率为92.0% (p值)结论:使用Ilizarov固定架，软件引导的复位对关节周围畸形的精确复位是有效的。这些装置即使在复杂的多平面畸形中也能同时提供多维矫正，并简化了畸形矫正的任务。临床意义:本研究使用畸形类别、DSS和个体畸形成分评分的新概念来评估软件引导调整的准确性和有效性，这可能克服传统评估方法的一些缺点。如何引用本文:Singh P, Sabat D, Dutt S，等。软件引导下骨性复位治疗下肢关节周围畸形的准确性和有效性。创伤肢体重建2021;16(2):65-70。

期刊介绍： Strategies in Trauma and Limb Reconstruction is dedicated to surgeons, allied medical professionals and researchers in the field of orthopaedics and trauma. The scope of the journal is to discuss the fields of skeletal injury, and the complications thereof, congenital and acquired limb deformities and deficiencies, and orthopaedic-related infection, together with their surgical and non-surgical treatments. The journal publishes original articles, reviews, case reports, descriptions of new or recognised treatment techniques, forum discussions of clinical scenarios and relevant correspondence. It aims to provide a widely accessible source of useful information to practitioners in the field through the problem- or technique-based approach of published articles.
