Abstract

OBJECTIVES

To present a simplified calculation for the measurement of osteotomy wedges used for the correction of angular uniplanar deformities of long bones and to compare the simplified calculation proposed (circumferential calculation) with the classical trigonometric calculations, as well as with the exact calculation performed by computer software AutoCADtm.

METHODS

The software AutoCADtm was used to calculate the bone wedges, for mathematical comparison of the three main groups, each one of them containing 18 hypothetical bone deformities which angles ranging from 5 to 90 degrees, with 5 degrees intervals between them.

RESULTS

In the analysis of 18 deformities, the hypothetical angular bone, the average lengths of the corrective wedges obtained by the trigonometric, circumferential and the exact metods were, respectively, 32.21 ± 16.81 mm, 33.16 ± 18.63 mm and 35.22 ± 23.52 mm. There was no statistically significant difference between the three calculation methods (p>0.05).

CONCLUSION

The circumferential calculation proposed in this study is useful for being accurate and simple, not requiring any trigonometric knowledge. Level of Evidence II, Experimental Study.

摘要

目的

介绍一种用于测量长骨单平面角畸形矫正截骨楔块的简化计算方法，并将所提出的简化计算方法（圆周计算法）与经典三角计算法以及计算机软件AutoCADtm进行的精确计算相比较。

方法

使用软件AutoCADtm计算骨楔块，对三个主要组进行数学比较，每组包含18个假设的骨畸形，角度范围为5至90度，彼此间隔5度。

结果

在对18种畸形（假设角骨）的分析中，通过三角法、圆周法和精确法获得的矫正楔块的平均长度分别为32.21±16.81毫米、33.16±18.63毫米和35.22±23.52毫米。三种计算方法之间无统计学显著差异（p>0.05）。

结论

本研究中提出的圆周计算法准确且简单，无需任何三角学知识，很有用。证据水平II，实验研究。
