Patient Success Stories

Watch success stories from Kenai Spine patients

Due to a herniated disc in her lower back, Jill was living in constant pain and leg numbness to the point that it was difficult for her to walk. After physical therapy and non-surgical injections did not relieve her pain, Jill decided to visit Kenai Spine. Dr. Humphreys diagnosed the herniated disc and recommended surgery. In just 5 weeks following surgery, Jill was able to take a Caribbean cruise vacation. In the following months, Jill remained active, ultimately losing 47 pounds after surgery since she was able to exercise again pain free.

As a heavy duty mechanic on the North Slope, Arthur relies on his hands to make a living. When his arms and hands started going numb, he knew he needed to seek help. Arthur visited Kenai Spine where he received Artificial Disc Replacement, a surgery that replaces the damaged disc with an artificial implant that is intended to replicate the function level of a normal, healthy disc and retain motion in the spine. One month after surgery, Arthur was nearly pain free and had regained the function and feeling in his arms and hands.
