Radiographic examination of extremities in surgical lengthening and/or correction of deformities is of crucial importance for the assessment of new bone formation. The purpose of this study is to confirm the diagnostic value of radiography in precise detection of bone parameters in various lengthening or correction stages in patients treated by limb-lengthening and deformity correction.
50 patients were treated by the Ilizarov method of limb lengthening or deformity correction at the University Orthopaedic Surgery Clinic in Skopje, and analysed over the period from 2006 to 2012. The patients were divided into two groups. The first group consisted of 27 patients with limb-lengthening because of congenital shortening. The second group consisted of 23 patients treated for acquired limb deformities. The results in both groups were received in three stages of new bone formation and were based on the appearance of 3 radiographic parameters at the distraction/compression site.
The differences between the presence of all radiographic bone parameters in different stages of new bone formation were statistically signficant in both groups, especially the presence of the cortical margin in the first group (Cochran Q=34.43, df=2, p=0.00000). The comparative analysis between the two groups showed a statistically significant difference in the presence of initial bone elements and cystic formations only in the first stage.
Almost no statistical significance in the differences between both groups of patients with regard to 3 radiographic parameters in 3 stages of new bone formation, indicates a minor influence of the etiopathogenetic background on the new bone formation in patients treated by gradual lengthening or correction of limb deformities.
在外科肢体延长和/或畸形矫正中，对四肢进行影像学检查对于评估新骨形成至关重要。本研究的目的是确认影像学在精确检测肢体延长和畸形矫正患者不同延长或矫正阶段骨参数方面的诊断价值。
50例患者在斯科普里大学骨科诊所采用伊里扎洛夫肢体延长或畸形矫正方法进行治疗，并在2006年至2012年期间进行分析。患者分为两组。第一组由27例因先天性肢体短缩而进行肢体延长的患者组成。第二组由23例接受后天性肢体畸形治疗的患者组成。两组结果均在新骨形成的三个阶段获得，并基于牵引/加压部位3个影像学参数的表现。
两组在新骨形成不同阶段所有影像学骨参数的存在差异均具有统计学意义，尤其是第一组皮质边缘的存在差异（ Cochr an Q = 34.43，自由度 = 2，p = 0.00000）。两组之间的比较分析显示，仅在第一阶段初始骨成分和囊性结构的存在方面存在统计学显著差异。
两组患者在新骨形成的3个阶段的3个影像学参数方面差异几乎无统计学意义，这表明病因发病背景对通过逐渐延长或矫正肢体畸形治疗的患者新骨形成的影响较小。
