Clubbing is a medical phenomenon which is seen in a variety of conditions. It's very hard to describe in words--you have to see it. Go to google image and type in clubbing to get an idea what a clubbed finger looks like. The nails almost look "swollen". There is an objective definition of the condition, but it won't mean anything if you don't have medical training.
Clubbing is often associated with medical conditions where there is a chronic amount of pus or infection hanging around for a long time for example:
Cystic fibrosis and other conditions resulting in bronchiectasis
bacterial endocarditis (an infection of a heart valve)
inflammatory bowel disease
Or it can be seen in conditions where organs are scarred:
idiopathic pulmonary fibrosis
Or in conditions where there is chronically low oxygen in the blood:
cyanotic heart disease
...uhhh, and I can't think of any more.
With your son and cystic fibrosis, there is constantly thick, tenuous secretions which eventually lead to destruction of the small airways in his lungs and these are areas where pus can hang out for long periods of time. This is why chest physiotherapy is so important for children/adults with CF.
Okay, after all of that, the fact that your child has clubbing is only an ancilliary symptom which goes along with the CF. It doesn't mean it's any worse or any better--it's just an associated finding.
