Bone Age Height Predictor
Read full descriptionHide full description
Bone Age Height Predictor is a focused clinical calculator for estimating predicted adult height (PAH) using the Bayley–Pinneau method, bone age, and pediatric growth inputs. Designed for pediatric endocrinologists, pediatricians, radiologists, orthopedic clinicians, and other healthcare professionals, the app supports the common workflow where skeletal age is already available and the next step is a tempo-adjusted adult height estimate. Enter bone age from a hand/wrist radiograph report or clinical assessment, and translate skeletal maturity into a practical height estimate in seconds. KEY FEATURES • Bayley–Pinneau prediction Uses bundled, offline, sex-specific tables to estimate predicted adult height from current height and skeletal age. • Growth tempo selection Choose Advanced, Average, or Delayed maturation to match the patient's growth pattern—an important Bayley–Pinneau variable that most consumer height apps omit. • Fast single-screen workflow Enter sex, growth tempo, current height, and bone age (years), tap Calculate, and review the result with a summary of the inputs used. • Sex-specific skeletal-age tables Separate lookup tables for boys and girls across clinically relevant skeletal-age ranges, with tempo-specific coverage. • Clear inputs and outputs Results display Predicted Adult Height alongside the sex, tempo, height, and bone age values used in the lookup. • Offline calculation Tables are bundled on-device—no network connection required for the core calculation. • Not a grow-taller or lifestyle app A professional calculation tool, not exercise, coaching, or height-hacking content. WHO IT IS FOR Bone Age Height Predictor is intended for healthcare professionals involved in pediatric growth evaluation, including: • Pediatric endocrinologists • General pediatricians • Radiologists • Pediatric orthopedic clinicians • Growth and puberty specialists • Medical trainees in pediatric endocrine settings IMPORTANT MEDICAL DISCLAIMER This app is a clinical calculation and reference aid for qualified healthcare professionals. It does not diagnose, treat, monitor, or prevent any disease or condition. It does not interpret radiographs, perform bone age scoring, or replace professional clinical judgment, radiology assessment, or individualized patient care. Predicted adult height estimates are approximations and should be interpreted alongside the patient's full clinical history, growth pattern, pubertal stage, family heights, exam findings, and applicable local standards of care.
