The superficial digital flexor tendon (SDFT) is that the most ordinarily affected and therefore the incidence of reinjures during this tendon is comparatively high (1, 2, 3, 4, 5). Tendinitis of the (SDFT) is additionally mentioned as “bowed tendon”, develops following excessive strain on the (SDFT) which causing tearing of the tendon fibers leading to a warm, painful swelling associated with it. Tendinitis is a potentially career limiting injury, which is one of the most frustrating athletic injuries involving the lower leg. If there’s complete laceration or rupture of the (SDFT) there’s reduced support for the fetlock. Damage to the (SDFT) most commonly occurs in the mid-metacarpal region or tensile region of the tendon (9, 10, 11, 12). Normal strain measured in (SDFT) range from (3-8 %) at the walk, (7-10 %) at the trot and (12-16%) at the gallop, thus it becomes obvious that a horse’s tendon is operating at or near maximal capacity whilst at the gallop. Tendon structures when injured do not heal as well Diagnosis of SDF tendinitis is based primarily on history, physical examination [13]. Treatment in lower leg tendinitis with time casing from injury to successful competition suggested as just over a year. The aims of cold therapy (ice) for acute tendinitis are to decrease inflammation and swelling, minimize scar tissue formation, and promote restoration of normal tendon structure and function as soon as possible for 20 to 30 minutes, 3 to 4 times per day. Cold therapy is commonly used in treatment of inflammation and soft tissue injuries in the horses, and no matter what the method of application. The amount of exercise and duration of protocol before re-examination are based on the severity of tendon damage at initial examination. The repair and maturation phases of healing in a tendon last for six month or more. Recovery from such injury is prolonged, and recurrence frequent after affected horses returns to training or racing.
