Correct Answer » A

Explanation

A felon is an infection of the distal pulp space of the finger, typically caused by Staphylococcus aureus. The pulp is divided into multiple compartments by fibrous septa, leading to increased pressure and severe pain when infected.

The index finger is the most commonly affected digit because:

  • It is used most frequently in activities
  • It is more prone to minor trauma and puncture injuries
  • Greater exposure increases infection risk

Felon is Subcutaneous abscess of the distal pulp space of the finger

Etiology

  • Most commonly Staphylococcus aureus

Pathophysiology

  • Closed pulp compartments → increased pressure → severe pain → risk of ischemia

  • Severe throbbing pain
  • Tense swelling of fingertip
  • Erythema
  • Possible fluctuation

  • Osteomyelitis of distal phalanx
  • Tendon sheath infection
  • Septic arthritis
