MANUAL MINORS
Finger pad infections, or felons, are bacterial infections affecting the soft pad of the fingertip. These infections are commonly caused by Staphylococcus aureus, typically following puncture wounds, cuts, bites, or handling contaminated objects. The infection leads to the accumulation of pus in the finger pad tissue, resulting in severe pain, swelling, and redness.
Diagnosis
The diagnosis is mainly clinical, based on the history of a previous wound or trauma, along with symptoms such as severe pain, localised swelling at the fingertip, and redness. In advanced stages, there may be fluctuation (the presence of palpable pus) and warmth in the area. X-rays are used to rule out osteomyelitis or foreign bodies in complicated cases.
Differential Diagnosis
Condition | Key Differences |
|---|---|
Paronychia | Infection around the nail, not at the fingertip. |
Subcutaneous Abscess | Collection of pus elsewhere in the hand, not limited to the finger pad. |
Cellulitis | Diffuse skin infection with broader extension, without localised pus accumulation in the finger pad. |
Herpetic Whitlow | Painful vesicles on the skin of the finger pad, without purulent abscess formation. |
Emergency Management
Immobilisation of the affected finger to reduce pain and prevent further damage.
Application of local heat (warm compresses) to help the abscess mature and facilitate drainage.
Administration of painkillers and anti-inflammatory drugs to manage pain.
If fluctuation is present, incision and drainage of the abscess under sterile conditions.
Oral antibiotics (such as cephalexin or clindamycin) for severe infections or if surrounding cellulitis is present.
Definitive Treatment
Definitive treatment involves complete drainage of the pus and wound cleaning. Antibiotics are prescribed for moderate or severe infections, or when there are signs of systemic spread. If the infection involves the bone (osteomyelitis), more extensive surgical intervention may be required. Patient monitoring is crucial to ensure the infection does not progress or recur.
