Below is a great article in regards to swaddling and hip dysplasia that was done for The Birmingham Parent magazine:
The IHDI has reached an important milestone with publication of our first research study that was fully funded by donations to the effort to cure hip dysplasia. This project was completed with the mechanical and aerospace engineering department at the University of Central Florida that is a world leader in simulation technology.
The scientific abstract is listed below but it sounds as complicated as a space project. What the IHDI doctors did was work with these highly recognized engineers to create a simulation model of a baby in a Pavlik Harness to validate that model with MRIs, CT Scans and anatomical studies of dislocated hips. Peer review is needed before publication in a respected journal like the Journal of Biomechanics. Peer review means that several independent and highly qualified scientists made sure that this model was developed correctly and that the information was reliable and accurate.
In the coming years, we plan to refine the model so we can modify strap positions, leg positions and other factors to see if we can reduce the more difficult hips. So far, we’ve identified some new findings about why the difficult ones don’t reduce, but we need to quantify changes in the harness. Until now, modifications and adjustments of the harness have been based on experience of the physician, but now we can begin to put some science behind it. Julie Zielinski, M.D. is joining the team from afar and will come to Orlando three times a year to review and collaborate. She is a young pediatric orthopedic surgeon at University of Tennessee with a mechanical engineering degree and two years of experience with General Motors in their crash test division before going to medical school. Her earlier publications form the basis for most of the car seat restraints of children in spica casts so DDH is a special interest for Dr. Zielinski.
As you might imagine, research is a slow and tedious process. This particular research has been underway for over three years and has required $90,000 of IHDI Funds even though our doctors, the professors at University of Central Florida and their graduate students have contributed hundreds of hours of time at no cost. This was money well spent because this allowed us to secure a $340,000 grant from the National Science Foundation to continue the work, make it more detailed, and find new ways to make the Pavlik Harness more successful plus new ways to teach others how to use the Harness effectively in difficult cases.
Any of you who have contributed to IHDI and especially Larry the Cable Guy’s Git-R-Done Foundation can be proud of this achievement and many more to come. Thanks

Mechanics of hip dysplasia reductions in infants using the Pavlik harness: A physics-based computational model.
Department of Mechanical and Aerospace Engineering, University of Central Florida, Orlando, FL 32816, United States.
Biomechanical factors influencing the reduction of dislocated hips with the Pavlik harness in patients of Developmental Dysplasia of the Hip (DDH) were studied using a three-dimensional computer model simulating hip reduction dynamics in (1) subluxated and (2) fully dislocated hip joints. Five hip adductor muscles were identified as key mediators of DDH prognosis, and the non-dimensional force contribution of each in the direction necessary to achieve concentric hip reductions was determined. Results point to the adductor muscles as mediators of subluxated hip reductions, as their mechanical action is a function of the degree of hip dislocation. For subluxated hips in abduction and flexion, the Pectineus, Adductor Brevis, Adductor Longus, and proximal Adductor Magnus contribute positively to reduction, while the rest of the Adductor Magnus contributes negatively. In full dislocations all muscles contribute detrimentally to reduction, elucidating the need for traction to reduce Graf IV type dislocations. Reduction of dysplastic hips was found to occur in two distinct phases: (a) release phase and (b) reduction phase.
Research project partnered with The International Hip Dysplasia Institute to be published in medical journal
A research project conducted with supervision and funding from the International Hip Dysplasia Institute has been accepted for publication in a prestigious journal. The title is a mouthful but we are on the road to a better understanding of how the Pavlik harness works, or why it doesn’t work in some cases. The first step was to create a computer model so that modifications can be studied in virtual reality instead of trial-and-error on infants. While computer modeling is not perfect, it is used in the automotive industry to design fuel efficient cars, and in the airline industry to test flight capabilities before new airplanes are constructed. Computer aided design allows rapid advances in theories that can be taken to the real world for application. The value of any computer model lies in its accuracy. The bio-engineers and computer engineers at the University of Central Florida are leaders in simulation technology with billions of dollars in research activities for military and entertainment simulation. The International Hip Dysplasia Institute is fortunate to be in proximity to such a wealth of computer simulation technology. Our physicians have combined their knowledge with these talented computer engineers to create a Pavlik harness simulation model. The paper is titled, “Mechanics of Hip Dysplasia Reduction in Infants Using the Pavlik Harness: a Physics-Based Computational Model” The research study has been peer-reviewed and accepted for publication in the Journal of Biomechanics.
This Pavlik harness simulation research recently received a boost when we were recognized by the National Science Foundation with an additional $340,000 grant to further refine the model. This additional funding will also allow us to apply the model to variations of hip dysplasia in an effort to determine methods for overcoming failures of reduction with the Pavlik harness. We can always use additional donations for this type of research.
Git-R-Done Foundation supports The International Hip Dysplasia Institute
The Git-R-Done Foundation is a proud supporter of The International Hip Dysplasia Institute(IHDI). Through a $5,000,000 donation from The Git-R-Done Foundation, the IHDI was established to bring together the top minds in the world in the field of hip dysplasia. The IHDI has started research projects that will hopefully, one day, be the cornerstone of diagnosing, preventing and curing hip dysplasia.
Larry the Cable Guy, Orlando Health Open Hip and Orthopedic Institute
Comedian’s $5 Million Gift Funds Development of Institute
Larry the Cable Guy (nee Dan Whitney) will be on hand at Orlando Health to open the Wyatt Whitney Hip & Orthopedic Institute.
The Wyatt Whitney Institute, which is named after the comedian’s five-year-old son, houses a number of specialists and resources dedicated to the treatment of hip and orthopedic conditions. It will emphasize collaboration between physicians and their teams to provide patients seamless, comprehensive orthopedic care from infancy through adulthood. Patients at the institute will have access to advanced pediatric and adult orthopedic services, sports medicine, physical rehabilitation services, and state-of-the-art imaging, along with research and educational resources to enhance their experience.
Development of the Wyatt Whitney Institute is possible because of the generosity of Larry the Cable Guy. Nearly two years ago, he and his family donated $5 million through the Git-R-Done Foundation to help fund development of the institute.
“We’re very appreciative of the generosity and optimism the Whitneys have shown in turning their son’s experience with hip dysplasia into an opportunity to help others,” states John Bozard, president of Arnold Palmer Medical Center and the Orlando Health Foundation. “Their gift will go a long way towards ensuring that we have the capability to help others do things like walk or run without pain or discomfort.”
Wyatt Whitney was born with hip dysplasia, meaning that the bones of the hip joint are not aligned correctly. It’s a condition that affects thousands of children and adults each year, and when it was first discovered in Wyatt, very little information about hip dysplasia was available anywhere.
That’s when the Whitneys began their search for answers and found Charles Price, MD, of the department of pediatric orthopedics at Arnold Palmer Hospital for Children and one of the world’s leading experts in hip dysplasia.
With help from Dr. Price, Wyatt successfully completed treatment for his hip dysplasia. The gift from the Whitneys allowed Price to work with other hip dysplasia experts around the world to develop the International Hip Dysplasia Institute (IHDI) as a source of information and guidance to families affected by the condition. IHDI also serves as a resource for medical professionals worldwide. It includes leading orthopedists working to develop better methods of detection, prevention and treatment of hip dysplasia.
In addition to housing IHDI, the Wyatt Whitney Institute is home to Level One Orthopedics, Orlando’s premier academic orthopedic center, where world-class orthopedic surgeons will continue their tradition of exemplary patient care, research, and education of the next generation of orthopedic surgeons.
“When we learned Wyatt had hip dysplasia as a baby, it was very difficult to find any good sources of information on his condition and it frustrated us that so little was being done to help kids like him,” stated Larry. “We were fortunate to find Dr. Price and get Wyatt the treatment he needed. It also created an opportunity for my wife and me to make a real difference in the lives of other people.”
Larry and the Git-R-Done Foundation continue to support Orlando Health with the annual “Git-R-Done Celebrity Golf Classic” held in Orlando. The two-day golf event features Larry and his celebrity friends raising money for The International Hip Dysplasia Institute. This year’s event is scheduled for November 4 -5.
To arrange an appointment at the Wyatt Whitney Institute, patients should call 321-843-DOCS.

Update from Dr. Charles Price and the IHDI (Nov. 2011)
We’ve made some good progress in several areas. One big one is that we are now ready to expand our “physician network” and identify good doctors so patients and parents can find qualified doctors in their region by visiting the IHDI website. We’ve agreed that we’ll have enough information from our research that we can plan for an educational course to promote some of the “best practices” we’ve identified. We expect to have some Practice Guidelines in a year so we’re planning our first course in 2013.
With all the patients we have in the database and the different treatments at 7 sites, we can answer some of the critical questions about treatment. We’re also going to add four more sites that have slightly different treatments than our seven. One will be in Norway, one in Germany, one in Israel and one more in USA (St. Louis). The USA one will make four sites in the USA, but the other three places use different braces than the Pavlik so their data should be interesting for comparison. This type of information could only be determined by collecting hundreds of cases from multiple sites that use slightly different treatment approaches. We’ve got that now and we’re growing even more. A thousand cases will make it even more reliable. It’s all pretty amazing to me.
