Idiopathic symmetrical shortening of the fourth and fifth metacarpal and metatarsal bilaterally. A case report.

A case of idiopathic bilateral symmetrical shortening of the fourth and fifth metacarpal and metatarsal bones in an active 10-year-old Caucasian female is described. The deformity did not result from trauma or an endocrine disorder and it was not hereditary. The function of the hands and feet was normal, and the only discomfort was of a cosmetic nature. Metacarpal or metatarsal lengthening therefore seemed unnecessary.
