To examine the correlation between spheno-occipital synchondrosis fusion stages and the hand-wrist skeletal maturity index.
Digital records of 164 individuals (77 males, 87 females) aged 10 to 18 years old were examined. Three-dimensional CBCT scans and hand-wrist two-dimensional radiographs were scored for the spheno-occipital synchondrosis fusion stages and hand-wrist skeletal maturity index, respectively. Statistical analyses were performed for associations using R software with a significance threshold of P< .01.
A significant positive relationship was demonstrated between spheno-occipital synchondrosis fusion stages and hand-wrist skeletal maturity in both sexes. The Kendall's rank correlation τ between hand-wrist skeletal maturity index and spheno-occipital synchondrosis fusion percentage were high and positive in males and females (r = .74 and r = .71, respectively).
The significant, positive relationship between the hand-wrist skeletal maturity index and spheno-occipital synchondrosis fusion stages support the idea of using spheno-occipital synchondrosis fusion as a biological indicator for craniofacial and mandibular growth spurt prediction.
研究蝶枕结合融合分期与腕骨骨成熟度指数的相关性。
检查了 164 名 10 至 18 岁个体（77 名男性，87 名女性）的数字记录。分别对蝶枕结合融合分期和腕骨骨成熟度指数进行三维 CBCT 扫描和二维腕关节 X 线片评分。使用 R 软件进行关联的统计分析，显著性阈值为 P<.01。
在男性和女性中，蝶枕结合融合分期与腕骨骨成熟度均呈显著正相关。男性和女性的腕骨骨成熟度指数与蝶枕结合融合百分比之间的 Kendall 等级相关系数 τ均为高正相关（r =.74 和 r =.71）。
腕骨骨成熟度指数与蝶枕结合融合分期之间的显著正相关支持将蝶枕结合融合作为预测颅面和下颌生长突增的生物学指标的观点。
