Hygroma

                            -------

                      General Information



Hygroma of the elbow is most frequently observed in large breeds

of dogs, such as the Saint Bernard, Great Dane, Irish

Wolfhound and Greyhound.  The condition usually develops when the

dog is relatively young, though older animals may be affected.



Hygroma is caused by repeated trauma to the elbow caused by the

dog's lying on hard surfaces.  A fluid-filled sac forms at the

elbow and progressively enlarges as the dog continues to lie on

hard surfaces.  The swelling may not be painful at first, but

later it may become very tender and inflamed.  If it remains

untreated, a hygroma can become ulcerated and may eventually

involve the underlying bone.



                 Important Points in Treatment



1.  General measures:  Treatment reduces the swelling, relieves

    discomfort and prevents recurrence.  Initial treatment is

    usually medical, though severe cases often require surgery.



2.  Elimination of trauma:  Eliminating the cause of the hygroma

    is the most important aspect of treatment and prevention.

    Your pet must be provided with soft bedding and prevented

    from resting its elbows on hard surfaces.  You can accomplish

    this by the use of an old mattress, heavy rugs, blankets,

    etc.  Do not confine your dog to an area where it is forced

    to lie on hard surfaces, such as concrete, wood floors or tile.

    * The hygroma is painful to your pet.



    * The hygroma increases in size.



    * Fluid or pus drains from the hygroma.
