Doctors at Sinai develop app that predicts your child's height

Ever wonder how tall your children will be when they grow up? There's an app for that.

Doctors at Sinai Hospital have developed a one-of-a-kind app that can predict your child's height, how long their legs will be, even their foot size.

The app is helping doctors treat kids with serious diseases.

Using crutches and wearing a brace isn't the way Jacob wants to get around. But it's all part of the healing process for him.

His mom Kristin Landis says, “He would have a ton of pain in this thigh and we thought at first he must've broke it so we got x-rays taken and nothing showed up."

Jacob's mom will never forget what happened next. After getting an MRI, he was diagnosed with perthes, a rare disease that causes the hip to collapse.

"The ball of the femur totally disintegrates down to nothing,” says Landis.

Jacob was treated at the International Center for Limb Lengthening at Sinai Hospital.

It's where a lot of kids like Jacob and Clayton Ambron go to get help.

They often have to undergo months of intensive treatment and surgery.

Dr. Shawn Standard, head of pediatric orthopedics has spent years treating kids with growth problems. Charting a course of treatment is complex.

So to make things easier for doctors and patients, Dr. Standard and his colleague Dr. John Herzenberg developed this unique app.

Dr. Herzenberg says, "We developed this app as a tool for doctors who treat children with growth disturbances to help them calculate how tall children will be and if they have a leg length difference how long that leg length difference will be when the children mature."

Dr. Standard says, "The app really helps me sit down with mom and dad and predict how much length we want to achieve this goal, how much we might have to achieve later on."

And not only is the app good for medical purposes, anyone can use it to find out how tall their child will be.

All you have to do is input some basic information.

Dr. Herzenberg says, "We developed the app for doctors but along the way many of our patients discovered it and started downloading it… and it may be of interest to the general public someone who wants to know how tall their child will be."

For Kristen and her son, it's a fun and easy way to get a glimpse into the future.

The app can be downloaded for free on apple and android phones. Just search for the multiplier app.
