Osteocartilaginous lesions of the digits in children: an experience with 10 cases.

Osteocartilaginous lesions, which are considered to be one of the most common neoplasms of bone, are seldom found in the hand. These are distinct from subungual exostoses or turret exostoses. When present in the hand in children, these lesions may limit function, cause cosmetic deformity, alter the growth of a digit, and pose a problem in diagnosis. Experience with these osteocartilaginous lesions in 10 children, (nine boys and one girl) is reviewed. Six patients had some degree of deviation or early rotation of the involved digit secondary to abnormal bone growth. There was no definite history of antecedent trauma; however, most parents assumed this to be a causative factor. Patients were treated by excision of the lesion and joint contouring when necessary. Follow-up ranged from 1.5 to 13 years, and there was good functional restoration, minimal growth disturbance, and no recurrence in any patient.
