Hip Surveillance at Your Fingertips

One in three children with cerebral palsy will develop hip problems and children with cerebral palsy are at increased risk for hip displacement and dislocation. If untreated, problems with walking , movement and sitting can occur.

Early detection through a hip surveillance program can preserve a child's function and prevent pain. HipScreen, a free app developed by physicians specializing in cerebral palsy, serves as an educational tool to help medical professionals, caregivers and parents understand and implement a hip surveillance program for children with cerebral palsy. The HipScreen App was developed by pediatric orthopaedic surgeons Vedant Kulkarni, M.D., and Jon Davids, M.D.

Vedant Kulkarni:

Welcome to Hip surveillance can identify hip displacement in children with cerebral palsy earlier, allowing for more effective and successful treatment. Unfortunately, substantial barriers to implementation of hip surveillance exist, including lack of education and challenges in the acquisition and interpretation of pelvis radiographs.

To overcome these barriers and to empower providers and caregivers, we created a free mobile app called HipScreen in 2016. HipScreen has easily navigable menus for understanding surveillance guidelines, protocols for proper positioning of radiographs, and a validated tool for measurement of x-rays directly from the device's screen. HipScreen was awarded the American Academy for Cerebral Palsy and Developmental Medicine's 2016 Fred P. Sage Award and is distributed as a public service by Shriners Children's at no cost, without tracking or data sharing, and free of advertisements or commercial content.

We hope that you use HipScreen and the training on this website to implement a hip surveillance program for children with cerebral palsy in your community. Thank you.


How hipscreen works

Early Detection. Better Function.

Hip Surveillance is a regular schedule of clinical examinations and X-rays for early detection of hip problems. Earlier detection means more successful treatment and better function.

HipScreen can help you start a Hip Surveillance Program for a child with cerebral palsy.

Learn the Science of Hip Surveillance

This section of the app will help you learn about the science and evidence supporting a Hip Surveillance Program in children with cerebral palsy. The information will help you: 

  • Assess a child with cerebral palsy with a focused hip exam
  • Obtain a properly positioned X-ray with a written standardized, downloadable protocol
  • Understand the important features of a hip surveillance X-ray

Get On Schedule!

Hip Surveillance is a schedule of X-rays and clinical examinations through childhood for early detection of hip disorders in children with cerebral palsy. Closer monitoring is needed for children with more severe cerebral palsy. This section of the app will help you classify cerebral palsy severity and provide a recommended screening schedule.

Makes Measuring an X-ray Easier

The most important X-ray measure to understand a child's risk of developing a progressive hip problem is the Migration Percentage, or the percent of the ball that is not covered by the hip socket. The Migration Percentage Ruler allows you to calculate this ratio more easily without having to measure distances.

Why Do Hip Surveillance**?

Children with cerebral palsy are at a high risk for developing progressive hip dysplasia, or malformation of the hip joint. Though children who do not walk are at highest risk, even those with mild cerebral palsy can have silent hip dysplasia that can become painful if not treated.

  • 1 in 3: Over 1/3 of children with cerebral palsy will develop hip displacement or dysplasia. Even children with mild cerebral palsy are at risk.
  • 1 in 5: 20% of children with severe cerebral palsy will develop a hip displocation.

Evidence from numerous studies shows that regular hip X-ray examinations can detect problems before they cause symptoms, allowing for earlier / more effective treatment. Hip Surveillance is a regular schedule of clinical examinations and X-rays during childhood, proven to improve function in children with cerebral palsy.

  • 50%: Half of children with a hip displocation will develop pain and problems with sitting, even if they do not walk.
  • ZERO: Sweden was able to completely eliminate hip dislocation in children with cerbral palsy using a Hip Surveillance Program.
