Orthopedic Biomechanics Research Center

OBRC logoMission

The Orthopedic Biomechanics Research Center (OBRC) complements and advances clinical decision-making and clinical understanding of orthopedic problems by using sophisticated analytical techniques incorporated from many different disciplines.

Scope

The OBRC focuses on common congenital deformities of the spine and complex joints while exploring novel methods of fracture fixation and surgical correction.

Staff

The ORBC is directed by Diana Glaser. Staff includes pediatric orthopedic surgeons, pediatric fellows, orthopedic residents, medical students, graduate engineering students and undergraduates, all of whom work together to design and complete all phases of each study.

Academic Partners

Equipment

  • Bi-axial MTS machine with custom-built attachments for physiological loading of spine, hip, upper and lower extremities
