Article Synopsis
- The study utilized modern hand x-rays and height data from diverse racial groups (Caucasian, Black, Hispanic, and Asian children) to assess developmental patterns based on percent final height (PFH), compared to the historical Greulich & Pyle Atlas.
- A retrospective analysis was performed to evaluate bone age (BA) and chronological age (CA) differences between races by analyzing data from 498 patients across different Sanders stages and employing statistical tests for significance.
- Results indicated that Black and Hispanic children often had a more advanced BA compared to White children, with significant age differences noted at the 85th PFH, suggesting variations in skeletal maturation among different racial groups.
Three-dimensional (3D) modeling using digital or printed models provides a unique perspective that caters to cognitive spatial ability in a way that can add to our understanding and mental representations of human anatomy. This is particularly useful in the setting of trochlear dysplasia, where the morphology of the groove can exhibit substantial variability and complexity. Using 3D reformatted images and models, a pragmatic understanding of how morphology influences patellofemoral pathology can be gleaned.

To create a new skeletal maturity system, an outcome variable, termed a "skeletal maturity standard," must be selected for calibration of the system. Peak height velocity and 90% of final height are both considered reasonable skeletal maturity standards for skeletal maturity system development.

Purpose: To investigate any association between femoral and acetabular versions with cam deformity in a largely asymptomatic population.
Study Design: Descriptive laboratory study.
Background: Follow-up scoliosis radiographs are performed to assess the degree of spinal curvature and skeletal maturity, which can be done at lower radiation exposures than those in standard-dose radiography.
Objective: Describe and evaluate a protocol that reduced the radiation in follow-up frontal-view scoliosis radiographs.
Materials And Methods: We implemented a postero-anterior lower dose modified-technique for scoliosis radiography with task-based definition of adequate image quality and use of technique charts based on target exposure index and patient's height and weight.
