Background
- Patients with systemic symptoms due to a hand infection are seriously ill and require inpatient management
Hand Anatomy
- Volar = anterior = palmar
- Dorsal = posterior
Nailtip Anatomy
- The perionychium includes the nail bed and the paronychium.
- The paronychium is the lateral nail fold (soft tissue lateral to the nail bed).
- 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.
