Humeral head ossification system placed in context of currently used standards for the determination of skeletal maturity including TRC, iliac apophysis ossification (Risser), hand scoring systems, and menarche. Boxes are indicated based on the stage containing the plurality of data at that time point. All ossification systems were measured on the same patients used to develop our humeral head staging system. Menarche for this dataset is likely unreliable for modern patients so a modern standard from our previous work has been used. Time relative to PGA was measured in years. PGA indicates peak growth age; TRC, triradiate cartilage closure.
