MRI scan prior to first ray amputation not associated with reamputation risk

In the moment: Diabetes

Obtaining an initial magnetic resonance imaging (MRI) scan prior to first ray amputation in patients with diabetes is significantly associated with a decrease in mortality rate but not reamputation rate, according to research from Staten Island, NY.

Investigators from Staten Island University Hospital retrospectively analyzed 368 patients with diabetes who had undergone a first ray amputation, and compared the rates of reamputation and mortality in those who had undergone an MRI scan prior to surgery and those who had not.

The researchers hypothesized that an initial MRI scan would improve surgical planning and postoperative care, reducing reamputation rates by allowing clinicians to identify osteo­myelitis and other pathologies that could negatively affect outcomes, as well as potential pressure points that could lead to subsequent ulcerations.

Although MRI was not associated with reamputation rate, the association with a decreased mortality rate suggests the MRI findings may have increased patient awareness of the need for diligent foot care, the authors wrote. The findings were published in June by Diabetic Foot & Ankle.
