U

 
      ulcer: irritation in the lining of the horse’s stomach or intestine.
     
      ultrasound: 1) a technique which uses ultrasonic waves to image internal
      structures such as soft tissues (tendons or ligaments).
     
      untried: 1) not raced or tested for speed. 2) a stallion that has not been
      bred.
     
      unwind: gradually withdraw a horse from intensive training. Let down.
     
      upward fixation of the patella: locking of the hind limb in an extended,
      stretched-out position due to the medial patellar ligament (which holds
      the kneecap in place) getting hung on a notch at the end of the thigh bone
      (femur). In affected horses, the locking occurs suddenly and without
      warning. Intial treatment may include anti-inflammatory medication on the
      assumption that the ligament and/or adjacent tissues are inflamed and
      swollen. Muscle-building exercise such as hill work is often recommended
      to improve strength, and dietary adjustment is used if necessary to
      improve body condition. If these measures fail, stifle injections can be
      considered or surgery.
     
      uveitis: inflammation and/or infection of the uvea, the colored iris of
      the horse's eye. Signs may include constricted pupil, watery eye,
      squinting and rubbing. If allowed to progress, uveitis can lead to
      breakdown of the eye's internal structures, detachment of the retina and
      blindness. Treatment includes frequent application of pupil-dilating
      ophthalmic medications as well as anti-inflammatory preparations such as
      dexamethasone or prednisone on the eye and/or systemically, systemic
      administration of nonsteroidal anti-inflammatory medications and detection
      and treatment of the underlying problem, if possible.
