乌鲁木齐地区汉族青少年手腕骨成熟度和颈椎骨成熟度的相关性

Correlation of Han adolescents's hand-wrist bone maturation and cervical vertebrae maturation in Urumqi region

背景:腕骨骨成熟度作为评价骨龄的金标准在临床应用广泛,但颈椎骨成熟度作为一项新的骨龄评价指标,以其经济,简便,临床可操作性强得到人们的广泛关注。目的:通过评价乌鲁木齐地区少年儿童手腕骨成熟度和颈椎骨成熟度的相关性,为临床正畸诊断和制定矫治计划提供依据。方法:选取在新疆医科大学第一附属医院口腔正畸科就诊的96例(男34例,女62例)年龄在9-15岁的错(?)畸形患者,治疗前同期拍摄左手腕骨片和头颅侧位片,X射线片图像质量良好,各观测指标均清晰可见,无重叠影像.分别评价腕骨成熟度和颈椎骨成熟度。结果与结论:乌鲁木齐地区汉族青少年腕骨成熟度和颈椎骨成熟度高度相关(男性r=0.703,P<0.01;女性r=0.728,P<0.01)。提示正畸治疗中,头颅侧位片上的颈椎骨影像与手腕骨影像一样可以作为判断患者生长发育状况的指标,而且拍摄头颅侧位片可避免患者接受额外的X射线辐射,减轻患者经济负担。

BACKGROUND： Hand-wrist bone maturation as the gold standard for evaluating of bone age has been widely used in the clinical work, but the cervical vertebrae maturation as a new bone age evaluation, with its economic, simple and strong clinical operability has get widespread attention. OBJECTIVE： To investigate the correlation between adolescants＇s hand-wrist bone maturation and cervical vertebrae maturation in Urumqi region, and to provide valid reference index for making diagnosis and treatment plan in orthodontics. METHODS： The lateral cephalograms and hand-wrist radiographs of the 96 cases （34 males, 62 females, 9-15 years of age） were taken before orthodontics treatment. The quality of X-ray image was good, and all the observation indicators were cleariy visible without overlapping images. Cervical vertebrae maturation and hand-wrist bone maturation were evaluated. RESULTS AND CONCLUSION： The correlation coefficient between cervical vertebrae maturation and hand-wrist bone maturation was high （r=0.703, P0.01 for males and r=0.728, P0.01 for females respectively）. The cervical vertebrae maturation and the hand-wrist bone maturation on lateral cephalogram were valid indicators on orthodontic practice to evaluate preciously patients＇ state of development and growth. And the cephalogram can avoid additional X-ray radiation that patients received, reduce the economic burden of patients.
