<prompt> Skeletal maturity is indicated by:CarpalsRadius, UlnaBoth 1 and 2None  <response>: Various methods have been proposed for assessment of skeletal maturity. These include:Chronological agePeak height velocity PHVDental ageHand-wrist radiographsCervical vertebral maturation index CVMI.Fishman 1982 developed the system for the evaluation of skeletal maturity on a hand-wrist radiograph and investigated its association with craniofacial growth. He called it skeletal maturation assessment SMA, which is based on skeletal maturity indicators.The system uses only four stages of bone maturation:Epiphyseal widening of the phalangesOssification of the adductor sesamoid of the thumbCapping of epiphyses over their diaphysisFusion of epiphyses and diaphysis.These stages of bone formation are found at six anatomical sites located on the thumb, third finger, fifth finger and radius.
