Hand infections account for around 1% of new Accident & Emergency attendances; their importance should not be underestimated as they can cause considerable disability.
Due to the complex anatomy of the hand, infections are usually confined to distinct compartments. By far the most frequent agent is Staphylococcus.
There is usually a history of trauma, often trivial, with subsequent pain and swelling in the hand. Systemic manifestations include pyrexial illness. On examination, the hand is red, tender, tense and restricted in movement.
Management is divided into general measures such as antibacterials and rest, and further steps dependent on the type, site and stage of infection.
