What's New in Multiplier HD

7.0

August 16, 2019

We added “Scanogram Calculations” under “Lower Extremity.” After entering the scanogram measurements, the screen will calculate the lengths of the individual femora and tibiae as well as the overall discrepancy for the limbs (using the femoral and tibial discrepancies). It will also provide the amount of each tibial and femoral discrepancy and whether each discrepancy is present on the right side or the left side. Under “Additional Resources,” we have added a new section called “Solomin Foot Analysis” that shows deformity correction planning for the midfoot, hindfoot, and ankle using reference lines and angles provided by Dr. Leonid Solomin. We improved the formatting of the data entry screens to reduce errors when inputting data. For example, units of length (cm or inches) no longer have a default unit selected; the user must choose the unit of length. We improved the formatting of the results screens to reduce errors in interpreting data. The Multiplier has been upgraded to support the latest iOS and improve its performance.

Great app

Great app. Very useful for patient and family counseling

Great app

Extremely useful, we'll-designed

Nice update for the Multiplier

Great new update to an already invaluable App that I use daily in my Pediatric Orthopedic Surgery practice. I especially like the new features that allow me to email calculation results to my secretary to file in the chart. The new calculations that display lengths at "every age" may become very useful for discussions with parents about future plans. Many thanks to the team at Sinai Hospital for updating this free App!

Extremely useful

This is an excellent app and easily replaces the dusty laminated charts which have cluttered clinic rooms in the past.

The developers are approachable and replied within 24 hours to my enquiries. An update is on the way in the near future.

Highly recommended for all Paediatric Orthopaedic surgeons.

FAQ

What is Multiplier HD used for?

Multiplier HD is a medical application designed to automate complex calculations for predicting a child's mature height and bone length. It assists healthcare professionals in various orthopedic calculations, including limb length discrepancy and growth remaining.

What types of calculations can Multiplier HD perform?

Multiplier HD can perform a wide range of calculations, including lower and upper extremity limb length discrepancy, growth remaining, bone length, timing of angular correction, and scanogram calculations. It also supports height and CDC growth chart plotting, achondroplasia measurements, fetal length prediction, and foot/spine measurements.

Does Multiplier HD provide information on skeletal age?

Yes, Multiplier HD includes resources for determining skeletal age by showing how to use radiographs of the elbow and hand. It also provides figures illustrating the development of apophyses, epiphyses, and bones.

Is Multiplier HD accurate for all growth predictions?

The app includes a disclaimer stating that no growth prediction method is 100% accurate. It emphasizes that Multiplier HD is a tool to assist clinical judgment and not a substitute for sound medical practice.

What additional resources are available in Multiplier HD?

Beyond calculations, Multiplier HD offers figures for standard limb and foot measurements, the multiplier formulae used, tables of multiplier values, the Solomin Foot Analysis, and a bibliography. A user guide is also included.

Does Multiplier HD collect user data?

No, Multiplier HD respects user privacy and does not collect, use, or distribute any data from its users. This aligns with the privacy policy of International Center for Limb Lengthening apps.
