The aim of this study was to assess the correlation between the Fishman maturation prediction method (FMP) and the cervical vertebral maturation (CVM) method for skeletal maturation stage determination. Hand-wrist and lateral cephalograms from 79 subjects (52 females and 27 males) were used. Hand-wrist radiographs were analyzed using the FMP to determine skeletal maturation level (advanced, average, or delayed) and stage (relative position of the individual in the pubertal growth curve). Cervical vertebrae (C2, C3, and C4) outlines obtained from lateral cephalograms were analyzed using the CVM to determine skeletal maturation stage. Intraexaminer reliability (Intraclass correlation coefficient [ICC]) for both methods was calculated from 10 triplicate hand-wrist and lateral cephalograms from the same patients. An ICC coefficient of 0.985 for FMP and an ICC of 0.889 for CVM were obtained. A Spearman correlation value of 0.72 (P < .001) was found between the skeletal maturation stages of both methods. When the sample was subgrouped according to skeletal maturation level, the following correlation values were found: for early mature adolescents 0.73, for average mature adolescents 0.70, and for late mature adolescents 0.87. All these correlation values were statistically different from zero (P < .024). Correlation values between both skeletal maturation methods were moderately high. This may be high enough to use either of the methods indistinctively for research purposes but not for the assessment of individual patients. Skeletal level influences the correlation values and, therefore, it should be considered whenever possible.
本研究的目的是评估用于确定骨骼成熟阶段的菲什曼成熟度预测方法（FMP）与颈椎成熟度（CVM）方法之间的相关性。使用了79名受试者（52名女性和27名男性）的手部-腕部和头颅侧位X线片。对手部-腕部X线片使用FMP进行分析，以确定骨骼成熟水平（提前、平均或延迟）和阶段（个体在青春期生长曲线中的相对位置）。从头颅侧位X线片中获取的颈椎（C2、C3和C4）轮廓使用CVM进行分析，以确定骨骼成熟阶段。两种方法的检查者内可靠性（组内相关系数[ICC]）是根据同一患者的10份重复的手部-腕部和头颅侧位X线片计算得出的。FMP的ICC系数为0.985，CVM的ICC为0.889。两种方法的骨骼成熟阶段之间的斯皮尔曼相关值为0.72（P <.001）。当根据骨骼成熟水平对样本进行亚组分析时，发现了以下相关值：早熟青少年为0.73，平均成熟青少年为0.70，晚熟青少年为0.87。所有这些相关值在统计学上均与零有差异（P <.024）。两种骨骼成熟方法之间的相关值为中度高度相关。这可能足以在研究目的中不加区分地使用任何一种方法，但不适用于个体患者的评估。骨骼水平会影响相关值，因此，只要有可能就应予以考虑。
