Skeletal age assessment in children and young adults: comparison between a newly developed sonographic method and conventional methods

Abstract

Although the US method promises to permit a safe and cost-effective assessment of skeletal age, its low accuracy makes it currently unsuitable for clinical use.

Radiographic versus ultrasound evaluation of the Risser Grade in adolescent idiopathic scoliosis: a prospective study of 46 patients

“…Only few studies have mentioned sonography as an image-guided alternative to examine bone age [3,6,7,24,36]. Wagner et al [36] described a high correlation between sonographic and radiological Risser Grade evaluation.…”

“…Castriota-Scanderbeg et al [7] investigated sonographic bone age determination in patients with proven or suspected growth disorder by measuring the thickness of the articular cartilage of the femoral head and compared it with the Greulich and Peyle and the Tanner-Whitehouse method. His ultrasound method agreed the least (difference in 4.19-5.13 years) with the other methods.…”

Análise da maturação óssea em pacientes de 13 a 20 anos de idade por meio de radiografias de punho

“…The patient's exact stage of maturation has been the target of research, which has sought to facilitate its assessment, reduce costs and reduce the exposure of patients to ionizing radiation. 1,5,18,19,24 Silva Filho et al 27 evaluated a simplified alternative method consisting of an X-Ray of the metacarpophalangeal joint area of the thumb, using a radiographic periapical film. In this film the presence of the ulnar sesamoid bone can be observed, in a clear indication that PGS onset will occur within a 1-year period, thereby signaling the correct time for the installation of the orthodontic appliance.…”

“…The difficulties in finding a procedure that combines a simple and accurate definition of normal variations with reasonable statistical confidence have surfaced in the design of different methods. 1,3,5,8,19,27 In contemporary Orthodontics, early correction of various types of malocclusion is rendered easier when it is possible to take advantage of the moments of maximum increment in an individual's facial and overall growth occurring during the PGS. 21 A patient's growth stage, therefore, proves essential in establishing accurate diagnoses and reliable prognoses.…”

Sonographic measurement of calcaneal volume for determination of skeletal age in children

“…1 Skeletal age has traditionally been determined by radiographic assessment of ossification centers, particularly those of the knee, wrist, and hand. Sonography has also been used to demonstrate the ossification centers, particularly those of the femoral head, 2 lower femoral epiphysis, 3 and wrist. 4 The aims of this study were (1) to prospectively evaluate the feasibility of determining skeletal age in children by sonographically measuring the volume of the ossified part of the calcaneus and (2) to provide the normal ranges of this volume for healthy children by sex in age groups from birth to 6 years.…”
