Brief Biography:
BS Mech Eng, 1994 (University of Iowa); MS Mech Eng, 1997 (Cornell University);
Wendy is a Ph.D. candidate in Biomedical Engineering at Cornell
University. She earned her BS in Mechanical Engineering at the
University of Iowa and her MS, also in Mechanical Engineering, at
Cornell University. Her research interests are skeletal growth and
development. Wendy is affiliated with the Vision and Image Analysis
Research Group headed by Dr. Anthony Reeves, her advisor.
Osteoarthritis is the leading cause of adult disability in the United States. Approximately 40% of idiopathic osteoarthritis
(OA) cases can be attributed to developmental dysplasia of the hip (DDH). While the endstage OA has been the subject
of much research, little is known, about the early postnatal development of the dysplastic hip. The objective of this
research is to quantitatively describe the temporal development of normal and dysplastic hips. A canine model of hip
development is used in conjunction with a longitudinal study design. Noninvasive evaluation of the hip joint using
computed tomography was performed periodically during growth. Image analysis techniques are being used to quantify
temporal changes in femoral head ossification size, shape and density distribution. Measures predictive of developmental
abnormalities will enable clinicians to diagnose and treat previously undetected cases of DDH. Characteristic features of
dysplastic hips will also enable clinicians to identify and proactively treat hips at risk for developing OA.
