CORE View metadata, citation and similar papers at core.ac.uk provided by University of Liverpool Repository Highlights CVM method is valid for identifying peak pubertal rate of growth in statural height. The peak rate of growth statural height occurred at CVM Stage 3 in boys and girls. At CVM Stage 3, girls were significantly older than the boys. Using a lateral cephalogram, the CVM method can be used to assess growth potential.

Cervical Vertebral Maturation as a Valid Predictor of Growth S. HOSNI* J. E. HARRISON and G. BURNSIDE (School of Dentistry, The University of Liverpool, UK) Objectives: The primary objective was to assess if a correlation exists between CVM and statural height growth velocity. The secondary objective was to assess if a correlation exists between CVM and mandibular growth velocity. Design/Setting: A prospective longitudinal study undertaken at Liverpool University. Subjects: Participants were aged between 8-18 years, of either gender and enrolled from the orthodontic waiting list at Liverpool University Dental Hospital. Methods: Standing height was measured every 6 weeks with subjects barefoot and in natural head position. Lateral cephalograms were taken at the start of treatment, on completing functional appliance therapy and prior to debond. Mandibular growth was assessed using the area of the triangle condylion-gnathion-gonion. Intra- and inter-observer reliability of CVM staging,...

Background Estimating skeletal maturation and growth potential is essential for developing adolescents' best orthodontic treatment plan. The purpose of this study was to compare the duration of adolescent growth peak in subjects of skeletal classes I and III using the cervical vertebral maturation (CVM) method. Methods This retrospective cross-sectional study included 116 Iranian subjects (skeletal class I = 68, skeletal class III = 48) aged 8–16 years old and without previous orthodontic treatments. Using Steiner and Wits analyses, two independent examiners traced pre-treatment lateral cephalograms to determine the subjects' skeletal relationship. The skeletal maturation was then assessed using Baccetti's CVM method. The onset and duration of adolescent growth peak (interval of CS3–CS4) were compared between two skeletal classes and two genders using independent samples t test. Results In skeletal class I and III subjects, the adolescent peak had a mean duration of 1.62...
Cervical vertebral maturation as a biologic indicator of skeletal maturity
The Angle Orthodontist, 2012
Objective: To identify and review the literature regarding the reliability of cervical vertebrae maturation (CVM) staging to predict the pubertal spurt. Materials and Methods: The selection criteria included cross-sectional and longitudinal descriptive studies in humans that evaluated qualitatively or quantitatively the accuracy and reproducibility of the CVM method on lateral cephalometric radiographs, as well as the correlation with a standard method established by hand-wrist radiographs. Results: The searches retrieved 343 unique citations. Twenty-three studies met the inclusion criteria. Six articles had moderate to high scores, while 17 of 23 had low scores. Analysis also showed a moderate to high statistically significant correlation between CVM and hand-wrist maturation methods. There was a moderate to high reproducibility of the CVM method, and only one specific study investigated the accuracy of the CVM index in detecting peak pubertal growth. Conclusions: This systematic review has shown that the studies on CVM method for radiographic assessment of skeletal maturation stages suffer from serious methodological failures. Betterdesigned studies with adequate accuracy, reproducibility, and correlation analysis, including studies with appropriate sensitivity-specificity analysis, should be performed.

Objectives: To perform a systematic review with meta-analysis to answer the question: is the cervical vertebrae maturation index (CVMI) effective to replace hand-wrist radiograph (gold standard) in determining the pubertal growth spurt in patients undergoing bone growth? Methods: A search in three databases was performed, in which studies were selected that compared one of the two main assessment methods for cervical vertebrae (Hassel B, Farman AG. Skeletal maturation evaluation using cervical vertebrae. Am J Orthod Dentofacial Orthop 1995; 107: 58-66, or Baccetti T, Franchi L, McNamara JA Jr. An improved version of the cervical vertebral maturation (CVM) method for the assessment of mandibular growth. Angle Orthod 2002; 72: 316-23) to a carpal assessment method. The main methodological data from each of the texts were collected and tabulated after. Later, the meta-analysis of the correlation coefficients obtained was performed. Results: 19 articles were selected from an initial 206 articles collected. Regardless of the method used, the results of the meta-analysis showed that every article selected presented a positive correlation between skeletal maturation assessment performed by cervical vertebrae and carpal methods, with discrepancy of values between genders indicating higher correlation for the female gender (0.925; 0.878) than for the male (0.879; 0.842). When the assessment was performed without gender separation, correlation was significant (0.592; 0.688) but lower in the cases when genders were separated. Conclusions: With the results of this meta-analysis, it is safe to affirm that both CVMIs used in the present study are reliable to replace the hand-wrist radiograph in predicting the pubertal growth spurt, considering that the highest values were found in female samples, especially in the method by Hassel and Farman.

Aim: The purpose of this study is to estimate and compare the duration of the pubertal peak in skeletal class II and class I subjects and to detect any difference between boys and girls or between hypo-, normo-, and hyperdivergent subjects for skeletal maturation indicator (CVM) in white Caucasians. Materials and methods: 346 subjects were selected from 3,119 examined files. Pretreatment lateral cephalometric records were hand-traced and divided following the anteroposterior skeletal relationship, the gender, the vertical pattern, and the skeletal maturation. The duration of the pubertal peak was calculated based on the chronological age interval according to each group. The age of onset of the active growth and the duration of the pubertal peak were compared between the different groups studied. Results: Pubertal peak had a mean duration of 13 months in skeletal class I subjects, 19 months in skeletal class II subjects, 15 months in girls, 20 months in boys, 13 months in normodivergent and hypodivergent subjects, whereas in hyperdivergent subjects, it lasted 18 months. Conclusion: The growth interval corresponding to the pubertal growth spurt (CS3-CS4) was (1) significant between skeletal class I and class II subjects, (2) longer in boys, and (3) longer in hyperdivergent subjects. Clinical significance: Orthodontic treatments can start earlier for girls in class I or class II relationship and for hyperdivergent subjects as well. Furthermore, boys and subjects in class II skeletal relationship have a significantly longer duration of the pubertal peak and consequently a much efficient orthopedic and orthodontic treatment.

Introduction: Pubertal growth stages are important periods in orthodontic treatment with functional appliances and orthognathic surgery. Pubertal growth prediction, which determines the amount of growth that has taken place and estimates the remaining growth, can influence diagnosis, treatment goals, treatment plans, and orthodontic treatment outcomes, especially in cases requiring growth intensity or growth completion. Determination of pubertal growth stages is more accurate when performed using physiological maturation indicators than chronological age. There are several maturation indices that can be used to predict the pubertal growth stage, such as hand-wrist maturation, cervical vertebrae maturation index (CVMS), dental calcification, peak height velocity of body height (PHV), and menarche in females. The aim of this study was to identify the differences and correlation between hand-wrist, CVMS maturation stages, peak height velocity (PHV), canine and M2 calcification stages, ...
Growth pattern of lumbar maturity stage at L1 to L5 during adolescent growth spurt
European Spine Journal
Purpose This study aimed to clarify the order of the lumbar maturity stage, each at L1 to L5, and the relationships between age at peak height velocity (APHV) and the lumbar maturity stage. Methods A total of 120 male first-grade junior high school soccer players were enrolled and followed for two years, and measurements were performed five times (T1 to T5). The lumbar maturity stage was assessed according to the degree of lesion of the epiphyseal from L1 to L5 using magnetic resonance imaging and classified into three stages: cartilaginous stage, apophyseal stage, and epiphyseal stage. The relationships between T1 and T5 temporal changes and developmental stages divided by 0.5 year increments based on APHV and the lumbar maturity stage at L1 to L5 were examined. For the apophyseal stage, developmental age calculated based on the difference between APHV and chronological age between each lumbar vertebra was compared. Results We found that part of the cartilaginous stages decreased a...

Purpose Adolescent idiopathic scoliosis occurs far more often in girls than in boys, and its initiation and progression normally takes place around the adolescent growth spurt. Despite extensive research into the topic, no solid explanation for both well-known phenomena has been offered. The sagittal profile of the growing spine has been demonstrated previously to play an important role in the spine's rotational stiffness. Changes in this sagittal alignment around the growth spurt can be inferred to play an important role in the spine's propensity to develop a rotatory deformity, i.e. scoliosis. The aim of this study was to quantify sagittal spino-pelvic alignment and orientation in space of each individual vertebra in normal boys and girls in the beginning, at the peak and at the end of pubertal growth. Methods Standardized lateral radiographs of the spine of boys (n = 57) and girls (n = 99) between the age of seven and eighteen who underwent screening for scoliosis, but had a normal spine were enrolled in this study. Children with spino-pelvic pathology at initial screening or during follow-up were excluded. According to Dimeglio's data, subjects were classified into three groups: before, at and after the peak growth spurt. Seven regional sagittal spinopelvic parameters, as well as the inclination angles of each individual vertebra between C7 and L5 compared to the gravity line, were measured semi-automatically using inhouse developed software. Results In all subjects, the posteriorly tilted segment was longer, vertebrae T1-T8 were more posteriorly inclined and thoracic kyphosis, pelvic incidence and pelvic tilt were lower before as well as during the peak of the growth spurt, when compared to after the growth spurt (P B 0.023). Furthermore, in girls, thoracic kyphosis was smaller (P = 0.023), the posteriorly inclined segment was longer (P \ 0.001) and T1 as well as levels T3-T11 were more posteriorly inclined (P \ 0.05) compared to boys at all stages of development. At the peak of the growth spurt, girls had more posterior inclination of upper thoracic vertebrae and lower values for thoracic kyphosis than boys (P = 0.005). Conclusions These results imply that the spines of girls during the growth spurt are more posteriorly inclined, and thus rotationally less stable, compared to boys at the same stage of development, as well as compared to girls after the growth spurt. This may explain why initiation and progression of adolescent idiopathic scoliosis are more prevalent in girls around puberty.
