Multiplier

-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 10 years at our annual Baltimore Limb Deformity Course (www.DeformityCourse.com). These calculations are typically performed by hand, using various formulas. Certain calculations are easy, but others involve more complicated formulas. Utilizing this App will reduce the time needed for these routine calculations, and decrease errors. You need only input the values about a patient (sex, age, length) and the App will execute the required 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) Limb Length Discrepancy and Epiphysiodesis
• 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
- Length of tibia or femur at birth and maturity
• Foot
- Foot Length
- Foot Length Discrepancy
• Spine
- Sitting Height at Maturity
•Bone Age: Elbow
- Shows a radiographic scoring system to determine skeletal age
• Bone Age: Hand
- Shows you how to use radiographic criteria to determine skeletal age
• Oblique Plane Deformity
- Calculates magnitude, orientation, and direction of an oblique plane deformity
• Inclined Osteotomy Rotation Angle
- Calculates the rotational orientation and the vertical inclination of the osteotomy


This APP also provides the following additional resources:
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 values that are used in the multiplier formulae, figures that show the development of the apophyses, epiphyses, and bones, a bibliography, and a user guide.

Disclaimer: No growth prediction method is 100% accurate; this App is not a substitute for sound and careful clinical judgment.

Great app for predicting limb length discrepancy and height. Easy to use. Cute, pediatric friendly interface. Also works well on iPad.


Can someone please answer?!?!

Hey, I'm 12 years old and a female. I am 4 foot 9 and a half and I haven't grown in 5 months. My mom is about 5 foot 2 and my dad is probably 5 foot 9. I weigh 84 pounds. I was wondering if anybody knew if I would grow any more?!? I really don't like being short... I dont know if this would have to do with anything, but I have started my period... So... Can someone write me back? Thanks.

This app is great for orthopedic doctors, their patients, and anyone who is interested how their bones grow.

It's a joke!! My dad is 6'0 and mom is 5'7


Horrible!!!!

I am a 12 year old girl and currently 5,7 I know wow!! But it said at maturity I'll be 5,9 I know that's not true because I grow 5 inches at least each year and I have no signs of slowing down yet!

This app is not accurate at all. There are too many factors to figure out future height than just age and current height. Apparently a day older or younger but the same height throws everything off.
