Radial Head Replacement Arthroplasty

Showing use of radial head implants in an elbow.

Dr. O'Driscoll is leading efforts to improve use of radial head implants (shown in red).

Through detailed biomechanical studies, Dr. O'Driscoll's research team is gaining a better understanding of the forces and factors necessary for elbow stability and function. In turn, this knowledge is leading to insights that are improving the approaches used to treat elbow injuries.

One focus area of research in Dr. O'Driscoll's lab is radial head replacement in elbow injuries.

Radial head fractures occur in up to 33 percent of elbow fractures. Indications for radial head replacement include fractures that can't be reconstructed, that are displaced or comminuted or that have associated ligamentous disruption.

Several types of radial head implants — with different head and stem configurations — are available. Although such implants have been used clinically for decades, much remains unknown about the biomechanics and kinematics of radial head prostheses.

Dr. O'Driscoll's lab continues to investigate the best solutions for these elbow injuries.
