Hip Dysplasia Frame
BME 401 Senior Design Project by Laila Thomas, Rin Iimi, and Madison Sergent
Need Statement
There is a need for a device that hospital medical staff use in operating rooms to stabilize pediatric hip dysplasia patients’ lower bodies during the casting process post operation to reduce variability in cast placement and complications during recovery.
Project Scope
Hospital medical staff need a device that can assist operating room physicians during
the casting process after hip dysplasia surgery to minimize variability in cast placement
and reduce risk of future complications. Since this casting process is currently manually
done by operating room staff directly after the surgery, fatigue and stress in these
conditions often cause the cast to not be molded in the optimal position for recovery, which
can cause various complications and even result in the femur dislocating out of the pelvis
again. The device developed will be capable of restraining the hip to 5% variability in hip
movement during the casting process to ensure proper placement of the cast. The device
will also be able to attach to operating room tables made by the top 3 manufacturers in the
United States so that most major hospitals will be able to implement this device. Finally,
the device will be inclusive of and adjustable to a range of the most prevalent ages (0 to 7
years old), heights (80 to 135 cm), and weights (8 to 32 kg) in which hip dysplasia is seen.
The device should be able to accommodate patients of both sexes and any common
material allergies.
