Explain pulp space infection.

Let's explain pulp space infection. A pulp space infection is an abscess that forms in the pulp space of the digits, often called a whitlow or felon. These infections are common because the fingertips are frequently exposed to injury. The accumulation of pus in this confined space causes severe throbbing pain due to rising tension. Treatment involves draining the pus through a lateral incision, ensuring all compartments (loculi) are opened while avoiding damage to the tactile sensation on the front of the finger. If a whitlow is neglected, the increased pressure can compress the digital artery, leading to avascular necrosis (tissue death due to lack of blood supply) of the distal four-fifths of the terminal phalanx. The proximal one-fifth of the phalanx (the epiphysis) is typically spared because the branch of the digital artery supplying this area does not pass through the pulp space, thus avoiding compression. 3 done, 2 left today.
