Ingrown toenail
Background
Nailtip Anatomy
A. Nail plate; B. lunula; C. root; D. sinus; E. matrix; F. nail bed; G. hyponychium; H. free margin.
- The perinychium includes the nail, the nailbed, and the surrounding tissue.
- The paronychia is the lateral nail folds
- The hyponychium is the palmar surface skin distal to the nail.
- The lunula is that white semi-moon shaped proximal portion of the nail.
- The sterile matrix is deep to the nail, adheres to it and is distal to the lunule.
- The germinal portion is proximal to the matrix and is responsible for nail growth.
- Lateral nail edge grows deep into nail wall → cycle of inflammation and hypertrophic granulation tissue can lead to abscess
