We present an unusual case of unilateral congenital quintus valgus of the left foot (congenital lateral deviation of the fifth [little] toe) in a 1.5-year-old boy. The child had no other congenital malformations. Radiographs revealed the abnormal presence of 2 accessory phalangeal ossicles in the fourth web space, leading to lateral deviation of the fifth toe. Remarkably, the ossicles of the middle and distal phalanges of the fifth toe were absent. Surgical excision of the accessory ossicles was performed, and correction of the deformity was achieved.Conclusion:
Congenital quintus valgus, to the best of our knowledge, has not been reported in the medical literature. Physicians must be aware of the possibility of such a condition while treating congenital malformations of the foot.
