Dynamic radiostereophotometer

A Canadian exclusive, the dynamic radiostereophotometer is used to accurately assess the performance of new joint replacement implants.

“The RSA is the orthopaedic surgeon’s best friend,” declared Dr. Martin Lavigne, orthopaedic surgeon at HMR. “The information it provides is 20 times more precise than a PET scan or MRI, while allowing us to assess the potential success or failure of a joint replacement quickly, significantly enhancing patient follow-up in the process,” he added.

Because it allows for better assessments both before and after the operation, RSA reduces the cost of hip or knee replacement surgery, in particular by lowering the number of revision procedures required. It is worth noting that more than 700 joint replacement surgeries are performed at HMR every year, most of them on young, active patients.

A $700,000 investment

The purchase of the RSA machine was made possible by proceeds from the 2012 and 2013 annual HMR Foundation golf tournaments. “We are very grateful to the HMR Foundation,” said Dr. Lavigne. A big thank-you goes out to the event’s volunteers and organizing committee. We are delighted to have been able to introduce this machine earlier this year,” he said.
