Multiplier HD vs ICODE Hip US Calculator

-The Multiplier App automates calculations to predict mature height and bone length in children. This method was created originally in Baltimore at the University of Maryland, and subsequently developed at the International Center for Limb Lengthening (ICLL), Rubin Institute for Advanced Orthopedics (RIAO), Sinai Hospital of Baltimore. -We have taught the Multiplier Method for more than 19 years at our annual Baltimore Limb Deformity Course (www.DeformityCourse.com). These calculations are typically performed by hand, using various formulae. Certain calculations are easy, but others involve more complicated formulae. Utilizing this app will reduce the time needed for these routine calculations and decrease errors. You need only input certain data (sex, age, length) and the app will calculate the answer by using the appropriate Multiplier formula. The Multiplier App will allow you to make the following calculations: • Lower Extremity - Limb Length Discrepancy (LLD) (Congenital) - LLD (Developmental) - Growth Remaining - Bone Length - Timing of Angular Correction - Timing of Epiphysiodesis - Comprehensive (Congenital) LLD and Epiphysiodesis -Scanogram Calculations (calculates femur/tibia lengths, overall limb length discrepancy, and amount/side of femur/tibia discrepancies) • Upper Extremity - LLD (Congenital) - LLD (Developmental) - Growth Remaining - Bone Length • Height and CDC Growth Charts (calculates height at maturity, calculates height at every age, and plots the patient’s height and weight on the CDC growth charts) • Achondroplasia - Height - Sitting Height - Leg Length • Fetus (calculates the length of tibia or femur at birth and maturity) • Foot - Foot Length - Foot Length Discrepancy • Spine (calculates sitting height at maturity) • Oblique Plane Deformity (calculates magnitude, orientation, and direction of an oblique plane deformity) • Inclined Osteotomy (calculates the rotational orientation and the vertical inclination of the osteotomy) This app also provides the following additional resources: -Bone Age: Elbow and Hand (shows how to determine skeletal age by using radiographs of the elbow or hand) -Figures that show the standard measurements for the lower limb and foot -The multiplier formulae that the app uses to perform the calculations -Tables that show the multiplier values that are used in the formulae -Figures that show the Solomin Foot Analysis (deformity correction planning for the midfoot, hindfoot, and ankle using reference lines and angles provided by Dr. Leonid Solomin) -Figures that show the development of the apophyses, epiphyses, and bones -Bibliography -User guide Disclaimer: No growth prediction method is 100% accurate; this App is not a substitute for sound and careful clinical judgment. Privacy Policy: We respect the privacy of the people who use International Center for Limb Lengthening apps. The Multiplier app does not collect, use or distribute any data from the users.

The application is intended for use only by healthcare professionals. The main goal of the application is to be an easy-to-use and useful tool for calculating a babys hip type. The healthcare professional will provide some basic information about the baby after examination like the baby birth date, date of examination and both infant hip angless (in degrees). Based on an algorithm the application will display a result abount the infant's hip type. Also instructions are displayed based on the result. Healthcare professionals who use it, do so at their own risk and should exercise their own clinical judgment as to the information they provide to the patients. We have tried to create content to conform to the standards of professional practice that prevailed at the time of development. However, standards and practices in medicine change as new data become available and the individual medical professional should consult a variety of sources. Medical information changes rapidly.
