Sarah Twomey is the Founder and Chairperson of Healthy Hips Australia, a nationally registered not-for-profit organization working to improve awareness, support and early diagnosis for hip dysplasia in Australia. Despite being an occupational therapist, when both her daughters were diagnosed, Sarah found herself overwhelmed and uninformed about the condition, and how best to manage with the day-to-day challenges posed during treatment. Working closely with several paediatric Orthopaedic services and specialists across Australia since 2015, Sarah and Healthy Hips are thrilled to align with the global mission of the IHDI.

Member
International Advisory Committee

Natalie Trice is based in the UK and her second son was born with Developmental Dysplasia of the Hip (DDH) which changed the course of their lives. Lucas’ brave journey, inspired Natalie to write ‘Cast Life – A Parent’s Guide to Hip Dysplasia’ to help others and raise awareness of this common, but often unrepresented condition. Together with the help of leading orthopaedic surgeons, experts and other parents, Cast Life covers pretty much everything parents, carers and even professionals, need to know about DDH and how to deal with whatever comes their way.

Natalie also set up DDH UK, a charitable trust and their online forum supports hundreds of people around the world each year.

When she isn’t raising awareness of DDH, Natalie has a PR and writing business and enjoys spending time on the beach, near her home in Devon, with her husband, two boys and dog, Dotty.

I was diagnosed with hip dysplasia in my early 30s and underwent hip preservation surgeries in 2015 and 2016. I became involved with the IHDI when the organization assisted me in developing my Miles4Hips initiative to run my first 100 mile race in an effort to raise hip dysplasia awareness and support for the IHDI. As a patient, medical provider, researcher, and hip dysplasia advocate, I feel strongly in participatory medicine and believe that patient care and outcomes can be optimized when patients, healthcare providers, researchers, and supporting agencies collaborate to achieve a common vision. I truly believe that the IHDI has the potential to change the outcomes of infants, children, and adults with hip dysplasia ,and am honored to support the vision of this incredible organization and all of their efforts to make it a reality.

Cara Whitney

Cara Whitney

Chairman
International Advisory Committee

Cara Whitney first became aware of hip dysplasia when her son Wyatt was born with the condition. She quickly came to find that not only is hip dysplasia very common, but also that there was very little universal information out there about the condition. The IHDI was born out of the idea that parents and patients have access to the best, most trusted, universal information. The IHDI is where people can be best informed about hip dysplasia patient options and care. Cara lives with her husband, Dan, and two kids on a horse farm in Nebraska.
