Case Study

ToniWeb.jpg

Toni is a 7-year-old female spayed pit bull terrier who presented to another facility for persistent front leg lameness. She was referred to CARE Veterinary Center in October 2014 after her radiographs revealed bilateral RUIN lesions and supraspinatus tendonitis. Bilateral means on both sides. RUIN stands for radial ulnar ischemic necrosis. The first two words describe the location. The radius and ulna are the two bones that make up a forearm. The last two describe the type of bone damage. Ischemia is an insufficient supply of blood and necrosis in the structural changes seen with cell death. Supraspinatus tendonitis is inflamation of the tendon that attaches the upper arm to the should. Toni was initially treated with rest, NSAIDs, therapeutic ultrasound and laser therapy. She responded to treatment by January 2015.


Her owners returned to the rehabilitation department at CARE when Toni became symptomatic again in late April 2015. Her treatment this time was rest, a different NSAID, therapeutic laser and ultrasound. Her owners elected to proceed with more aggressive therapy in hopes of not having her symptoms recur and hyperbaric oxygen therapy (HBOT) was added.


The HBOT treatments aid in decreasing inflamation and promoting bone healing. After ten treatments which were completed over the course of one week, the lameness had resolved and the radiographs showed improved bone density. We are pleased to report that Toni has continued to do well since her hyberbaric oxygen therapy treatments.
