The relative stage of maturity of a child may be determined by comparing the child's hand-wrist radiograph to known standards of skeletal development. Hand-wrist radiographs of 70 adolescents were used to categorize the individuals by skeletal maturation into early, average and late maturation groups using the Fishman SMA method of assessment. The rates of mandibular and maxillary growth relative to the last stages of the pubertal growth spurt were measured. Statistical evaluation of the data was performed using an analysis of variance. The magnitude of change in growth increments of the mandible was greater in the late maturers than in the early or average maturers. Incremental differences in growth between the maxilla and mandible during the last stages of puberty were noted, with the mandible growing significantly more than the maxilla.
儿童的相对成熟阶段可通过将其手部腕部X光片与已知的骨骼发育标准进行比较来确定。使用70名青少年的手部腕部X光片,采用菲什曼SMA评估方法,根据骨骼成熟度将个体分为早熟、平均成熟和晚熟组。测量了下颌骨和上颌骨相对于青春期生长突增最后阶段的生长速率。使用方差分析对数据进行统计评估。晚熟者下颌骨生长增量的变化幅度大于早熟者或平均成熟者。在青春期最后阶段,上颌骨和下颌骨之间的生长增量存在差异,下颌骨的生长明显多于上颌骨。
