In simple words: A valgus deformity of the ankle means the foot bends outwards at the ankle. This can cause pain, inflammation, and difficulty walking.
Valgus deformity of the ankle, not elsewhere classified. This condition involves the angulation of the distal bones of the ankle joint, causing the foot to turn outward, away from the midline of the body.
Example 1: A patient presents with pain and outward turning of their right foot at the ankle following a sports injury. Imaging confirms a valgus deformity., A child with a congenital condition exhibits an outward turning of both feet. This is diagnosed as a bilateral ankle valgus deformity., An adult experiences increasing pain and difficulty walking due to a progressively worsening valgus deformity. They opt for surgical correction.
Documentation should include details of physical examination, range of motion, imaging results, and any associated symptoms.
