Comparison of abnormalities in the sequence of growth stages in the skeletal maturity index vs cervical vertebral maturation:

Abstract

Objectives To evaluate the frequency of abnormal progression that could ultimately affect the reliability of the skeletal maturity index (SMI) and the cervical vertebral maturation (CVM) method that are most commonly used analyses for skeletal age assessment. Materials and Methods A retrospective design was used to compare 299 hand-wrist radiographs with 299 lateral skull radiographs regarding the number of abnormalities in the proposed sequence of maturation in the SMI and CVM methods. Results A significantly greater number of abnormalities occurred in the sequence of CVM progression compared with SMI (P < .001). Sex and age did not have an effect. Conclusions Skeletal age assessment based on SMI is more accurate than CVM regarding the progressive sequence of stages.

Prediction of Fishman’s skeletal maturity indicators using artificial intelligence

“…Clinicians often encounter hand-wrist radiographs with osseous maturational characteristics that are ambiguous to be classified as a certain SMI stage 29 . In case of individual variations in the sequence of skeletal maturation that do not comply with the descriptions by Fishman, SMI stage may be over- or underestimated depending on the observer, and reproducibility and reliability of SMI may be affected.…”

Comparative Evaluation of Wrist and Cervical Vertebral Maturation in Different Craniofacial Growth Patterns: A Preliminary Study

“…CVM yöntemi kullanımının, bazı araştırmacılar tarafından el-bilek filmleri kadar doğru olduğu düşünülmüştür. 4 Ancak Gabriel ve ark. 5 tarafından CVM indeksinin zayıf tekrarlanabilirliği bulunmuştur ve düşük tekrarlanabilirliğe ek olarak, CVM son zamanlarda mandibular büyüme dönemi ile korelasyon göstermediği için eleştirilmiştir.…”
