Because You May Not Need Surgery After All

You Owe it To Yourself to Find Out How We Can Help

Former Athlete Turned Orthopedic Specialist Offers Cutting-Edge, State-of-the-Art Treatments to Bring Relief FAST!

Dear Friend, If you are an athlete or active person suffering from sports or movement related injuries or chronic pain, I can help.  As a collegiate athlete I dealt with the common injuries associated with baseball and football, and my unique real-world experiences gave me both a passion and a unique perspective that will be valuable in helping you.  I understand many of the injuries, rehabilitation treatments and protocols as I've been through many myself.  Upon completing college I made it my life's mission to research and improve ways to more rapidly and effectively treat and heal anyone suffering from sports or movement injury, including spine issues.  With advanced training and technology, we now have ways to utilize your own cells to treat and heal your body.  Older methods, while they can be temporarily effective, often led to chronic issues down the road, with the short term benefits causing long term problems.  So my personal challenge was to find and perfect healing methods without negative long-term effects, and pass those on to my patients. I urge you to schedule an initial diagnostic consultation to find out how we can help should you choose to utilize our practice.  Warmly,  Dr. Steve Derrington Derrington Orthopedics - Interventional Sports and Spine

  I found Dr Derrington as I was searching for a way to avoid surgery for a nonunion fracture in my big toe. Combine his expertise & bedside manner with his staff plus the technology he uses, and you have a winning combination. Dr D performed a stem cell transfer and PRP in July, and 5 weeks post-procedure a high-res X-ray revealed the fracture was completely healed. I am beyond grateful to have avoided surgery and be able to get back to the activities I enjoy most. Thank you, Dr. D!

My Testimony 1

  Dr. Derrington helped me overcome a lingering case of plantar faciitis. He is very approachable and has a very pleasant and straightforward communication style. He engages the patient holistically and looks at the patient's concern in a larger context. He is thoughtful in suggestions on lifestyle adjustments. He looks for the least complicated solution first. His recommendation of a platelet treatment to my heel worked marvelously and I was back jogging in a few weeks. I recommend him highly.

  I found Dr Derrington as I was searching for a way to avoid surgery for a nonunion fracture in my big toe. Combine his expertise and bedside manner with his staff plus the technology he uses, and you have a winning combination. Dr D performed a stem cell transfer and PRP in July, coordinating fabulously with my podiatrist (who was deeply impressed with his technique and thoroughness). I am beyond grateful that 5 weeks post-procedure a high-res X-ray revealed the fracture was completely healed. I hope I don't incur any future injuries that point to PRP or a stem cell transfer, but if I do, I know exactly who to see! Thank you, Dr Derrington!
