The Southwestern Academic Limb Salvage Alliance (SALSA) has a broad social interest in healing people and keeping them healed. We envision a future where we can help people stay  active and informed as they move through their life and their world. We also believe that every day we see glimpses of the future in our clinics, in the operating room, in our iCAMP laboratories, and in our community.We want to help to leave a legacy of improving mobility and stability, worldwide.At its core, SALSA is a collaborative clinical and research alliance that is dedicated to advancing care of the diabetic foot and preventing amputations in North America and worldwide.   SALSA is the most productive research unit of its kind in the world and, with more than 10,000 patient visits per annum is one of the busiest such clinical units.

Here’s how two chefs in the kitchen can save limbs, help lives and make SALSA.

Our SALSA Team in consists of physicians, surgeons, engineers, and scientists from 14 nations.

Translational and mHealth Research 
Clinical trials are a key part of our research mission. These trials are led by UA surgeons, and the faculty collaborates with investigators in other programs as part of a multidisciplinary team offering the widest treatment options to patients.  The scope and breadth of the current research includes expertise ranging from outcomes-based research in vascular reconstruction to tissue regeneration to 3D printing and the fusion of consumer electronics with medical devices.

SALSA’s Interdisciplinary Consortium on Advanced Motion Performance (iCAMP) includes expertise not only from physician and surgeon-scientists, but also biomedical engineering, microbiology, app development, chemistry, optics, and architecture. It conducts next-generation high-value research ranging from development of intelligent textiles to fall prevention to exploration and phenotyping of the human microbiome.


Location and Resources

The Division of Surgical Research is located in state-of-the-art laboratory and tissue culture facilities. Staff and faculty of the division provide advice and assistance in study design, conduct both basic science and translational research studies and analyze collected data.
