Regenerative medicine has opened new doors for us as doctors,” says Dr. Kerry Zang, podiatric medical director, CiC Foot & Ankle. “Instead of just treating the symptoms and pain, we are able address the root cause of many different conditions and have the potential to fix what’s causing the problem.”

The newest form of regenerative medicine is amniotic-derived fluid or growth factor injections. This type of injection is one of the most promising and safe alternatives to managing chronic foot pain caused by injury, plantar fasciitis, arthritis, neuropathy or even residual pain from prior surgery. “This therapy stimulates the body’s own natural healing process to repair chronically damaged tissue,” explains Zang. “This is exciting because patients who’ve been living with foot pain who have had treatment that didn’t work, now have a chance of feeling better.”

Dr. Zang started practicing in Mesa, Arizona in 1970. He recently joined Comprehensive Integrated Care as the podiatric medical director of its foot and ankle division. He is Diplomate of the American Board of Podiatric Surgery, a Fellow of the American College of Foot & Ankle Surgeons and Chairman of Axolotl Biologix’s Medical Advisory Board.

An innovator in his field, he has recently developed a new, non-surgical treatment protocol for neuropathy of the feet. He has designed implants and surgical devices that are currently being used by surgeons across the country. Dr. Zang is also the co-author of several papers, including a placebo-controlled randomized study on Low-Level Laster Therapy at 635nm for Treatment of Chronic Plantar Fasciitis published in The Journal of Foot and Ankle surgery.

Respected among physicians for his unique diagnostic skills, he is often consulted on complicated and challenging cases. During his years in practice, he has learned that one of the more important aspects of treating patients is listening.

“If your feet cramp, feel cold in bed at night, or if you think you have neuropathy, you need to find out what’s causing it,” says Dr. Shahram Askari. “In the past, patients have been given medications to suppress these symptoms, but now that we have the tools, I think it’s important to diagnosis the problem.” 

Often, patients are given medication to address their symptoms rather than to diagnose what is creating the problem. Through diagnostic technology we can identify why patients are experiencing the symptoms and often correct the why.

For many patients, these symptoms may be due to poor circulation. There are new diagnostic techniques that are now in use to learn if there are blockages in the blood vessels below the ankle. “Discovering this condition can be life changing,” explains Askari. “If you’re not finding relief with your current treatment, it’s important to know other potentially more effective options may be available.”

Dr. Askari graduated from the College of Podiatric Medicine, Temple University in Philadelphia, Pennsylvania and completed his residency at St Luke’s Medical Center in Phoenix, under the directorship of Kerry Zang, DPM. Dr. Zang was so impressed with his abilities and compassion, he asked him to move his family to Arizona and join Arizona Institute of Footcare Physicians. They have worked together since 2005.

He recently lectured at the Superbones Superwounds East Conference in New Jersey on “Regenerative Medicine Therapy in a Clinical Setting.” Dr Askari is also the co-author of “Low-Level Laser Therapy’s Impact on Small Fiber Neuropathy,” published on podiatrytoday.com.

Dr. Askari joined CiC Foot & Ankle in April. He is excited to be part of a compassionate team committed to giving patients the highest-quality care possible. In addition to specializing in rheumatoid reconstructive foot surgery, he also treats conditions ranging from bunions, hammertoes and ulcers to ingrown nails, heel pain, and ankle sprains.

Daniel Schulman, DPM

“Getting patients back to their normal activities is the most gratifying part of what I do,” says Dr. Schulman, who joined CiC Foot & Ankle in April. “It seems like a little thing, but a painful bunion can really impact your lifestyle.” 

 Inspired by treating multiple metal allergic patients while having his own nickel allergy, Dr. Schulman researched and developed an implant made from human cadaver bone for patients needing a bunionectomy, hammertoe correction or fracture repair. This implant holds bones together in a way that over time it completely becomes part of their own bone.

 This implant option lowers the possibility for a second surgery. “Having a metal implant may potentially cause problems like an allergic reaction or rejection,” explains Schulman. “I believe it’s a more natural solution that will give the best outcome because it’s material your body already knows.”

Dr. Schulman earned his Doctor of Podiatric Medicine degree from the prestigious Scholl College of Podiatric Medicine in Chicago, Illinois in 1997. He completed his residency training as Chief Podiatric Surgical Resident at St. Luke’s Medical Center in Phoenix, under the guidance of Dr. Kerry Zang. He is a Fellow of the American College of Foot and Ankle Surgeons and a member of the American Podiatric Medical Association.

In April 2019, he joined CiC Foot & Ankle in Sun City. Dr. Schulman is excited to be part of team of interventional radiologists and vein specialists who are trained to treat the underlying vascular issues faced by those living with neuropathy and diabetes. Prior to that he was with Arizona Institute of Footcare Physicians in Mesa and Phoenix.

Dr. Schulman takes care of foot problems affecting both children and adults, from surgically correcting a wide range of foot deformities to non-surgical conservative care utilizing advanced regenerative medicine techniques. He also provides care for people living with diabetes, ingrown nails and non-healing wounds. To learn more, www.linkedin.com/in/dr-daniel-schulman-90970a6/.

Joshua Cady, DPM

Dr. Cady specializes in diabetic wound care, limb preservation and trauma. He likes to work closely with his patients, because he believes that together they have a better chance of reducing the risks many diabetics face because of their disease.

“Having diabetes puts people at higher risk for foot problems that can lead to amputation if they’re not cared for,” says Dr.  Cady. “If you are living with diabetes, you should check your feet every day for sores, redness or swelling. Any changes to the way your feet look or feel should be reported to a doctor right away.”

Dr. Cady graduated from Midwestern University Arizona School of Podiatric Medicine.  He completed his residency at First Nations Podiatric Residency Program, in Tuba City, with added credentials in Reconstructive Rearfoot and Ankle Surgery. He was a volunteer for LIGA International, Flying Doctors of Mercy, an organization that offers medical services to underserved people in rural Mexico. He spent time in San Blas, Nayarit providing foot care to those in need. Dr. Cady is the third generation of his family to provide care for Indian Health Services. Dr. Rainwater, CiC’s chief medical officer, was pleased to have him join the CiC team because of his special training and work with Native Americans as well as patients living with diabetes.

As part of the CiC team, Dr. Cady works closely with interventional radiologists who are specially trained to treat the underlying cause of problems. “Many diabetic complications in the foot are related to circulation,” he explains.  “If there is no blood flow, wounds won’t heal, legs will hurt, and nerves will die. These long-term consequences may be avoided if we’re able to restore blood flow.” This team approach leads to improved outcomes and better lifestyles for patients.
