Tendinitis is inflammation or irritation of a tendon, Tendons transmit the forces of muscle to the skeleton. As such, they are subjected to repeated mechanical loads, which are felt to be a major causative factor in the development of tendinopathy. Pathologic findings include tendon inflammation, mucoid degeneration, and fibrinoid necrosis in tendons. Microtearing and proliferation of fibroblasts have also been reported. However, the exact pathogenesis of tendinopathy is unclear.
The medical information database of Thoroughbred racehorses registered by the Japan Racing Association in 1999 was analysed for SDFT and SL overstrain injury diagnosed by a veterinarian employed by JRA during training and racing. Jump racehorses were excluded from this study. The prevalence of forelimb SDFT tendonitis and SL desmitis was 11.1% and 3.61% of the population, respectively. In the hindlimb, there were 0.06% and 0.14%, respectively.
Tendinitis may go away over time. If not, the doctor will recommend treatments to reduce pain and inflammation and preserve mobility to prevent disability and recurrence. He may provide a referral to a rheumatologist, an orthopaedic surgeon or a physical therapist for specialized treatment. When properly treated, most tendinitis conditions don’t result in permanent joint damage or disability.
