Abstract

PURPOSE

To discover whether there is a significant difference in carpal height ratio (CHR) between men and women aged 20 to 50 years.

METHODS

We retrospectively reviewed 261 cases of normal plain wrist radiographs and measured the CHR using the Picture Achieving and Communication System. Each case was then stratified by gender and age (20-29, 30-39, and 40-50 y).

RESULTS

The mean CHR was 0.52 +/- 0.03 for men (range, 0.43-0.59), 0.50 +/- 0.03 for women (range, 0.43-0.57), and 0.51 +/- 0.03 for the total population (range, 0.43-0.59). The difference in CHR between men and women was statistically significant (p<.01). However, there was no significant difference (p=.13) among age groups in either men or women.

CONCLUSIONS

We recommend using gender-specific norms (ie, 0.52 +/- 0.03 for men and 0.50 +/- 0.03 for women, respectively) for CHR. Without gender specification, a subtle abnormality may be overlooked in men, and there may be an overdiagnosis of carpal disorder in women. Further investigations are needed to look into possible racial differences, because our study is based on a homogeneous ethnic Chinese population.

摘要

目的

探究20至50岁男性和女性的腕高比（CHR）是否存在显著差异。

方法

我们回顾性分析了261例正常腕部X线平片病例，并使用图像获取与通信系统测量CHR。然后根据性别和年龄（20 - 29岁、30 - 39岁和40 - 50岁）对每个病例进行分层。

结果

男性的平均CHR为0.52±0.03（范围0.43 - 0.59），女性为0.50±0.03（范围0.43 - 0.57），总体人群为0.51±0.03（范围0.43 - 0.59）。男性和女性之间的CHR差异具有统计学意义（p<0.01）。然而，男性或女性各年龄组之间无显著差异（p = 0.13）。
