Abstract:
A 1year and 10 months old girl was referred by the general practitioner because of abnormal position of both big toes. Her mother had the same complaint, but only on the left foot. Clinical examination of the girl showed bilateral absence of the extensor hallucis longus tendons, while in the mother, the same anomaly was found only on the left side. Ultrasound confirmed the absence of both tendons and showed an aplasia of both muscle bellies in the girl: findings not previously reported in the literature.
