上海地区少年儿童颈椎骨成熟度与手腕骨成熟度的相关研究

目的:通过评价上海地区少年儿童颈椎骨成熟度和手腕骨成熟度的相关性,探讨利用颈椎骨成熟度评判生长发育阶段的可行性。方法:样本包括上海地区170例5～18岁(男52例,女118例)正畸就诊患者。治疗前同期摄取左手腕掌指骨片和头颅侧位定位片,分别评价手腕骨成熟度和颈椎骨成熟度(手腕骨采用Grave和Brown法,颈椎骨采用Hassel和Farman改良分期法)。以SPSS11.0统计软件包进行相关性分析(Spearman法)。结果:颈椎骨成熟度和手腕骨成熟度具有高度相关性。男性组r=0.858(P<0.01),女性组r=0.882(P<0.01);男女合并r=0.918(P<0.01)。结论:在正畸治疗中,头颅侧位定位片上的颈椎骨成熟度可作为判断少年儿童生长发育阶段的可靠指标。

Correlation of adolescents' skeletal maturation determined by cervical vertebrae and hand-wrist in Shanghai region

PURPOSE: The aim of this study was to investigate the correlation between the skeletal maturation determined by cervical vertebrae and hand-wrist, and to explore the possibility of using lateral cephalograms to evaluate physical development stages of orthodontic patients. METHODS: The samples were derived from 170 pairs of lateral cephalograms and hand-wrist radiographs taken before orthodontic treatment (52 males, 118 females; 5-18 years of age). Cervical vertebral development was evaluated by the method of Hassel and Farman. Hand-wrist radiographs were determined according to the method of Grave and Brown's system. The Spearman rank-order correlation coefficients were estimated for the samples, and for males and females respectively to detect the relationship between the two ways of skeletal maturation measurements using SPSS 11.0 software package. RESULTS: The spearman correlation coefficient was 0.918(P<0.01) between cervical vertebrae maturation and hand-wrist maturation for sexes combined, and 0.858 (P<0.01) for males and 0.882(P<0.01) for females respectively. CONCLUSION: The cervical vertebrae analysis on lateral cephalogram was a valid way on orthodontic practice to evaluate physical development stage of growing patients.
