tibial torsion
Rotational malalignment of the tibia, which can be internal or external, affecting foot progression angle during walking.
Full Definition
Tibial torsion refers to rotational malalignment of the tibia around its longitudinal axis, which can be either internal (causing in-toeing) or external (causing out-toeing). Internal tibial torsion is common in infants and typically improves with growth and weight-bearing activities. External tibial torsion is less common and may be associated with lateral tibial bowing or other deformities. Clinical assessment involves measuring the thigh-foot angle with the patient prone and knees flexed. Most cases resolve spontaneously, but severe persistent torsion may require surgical intervention through tibial osteotomy in older children.
Usage
Usage note: Specify internal or external torsion; include degree measurements when available.
