title: Neglected nonunion of phalangeal neck fractures of the thumb in children: the outcome of delayed bone grafting in adulthood.
abstract: Over a 12-year period, the author treated a total of 5 adults (mean age, 23 years) with neglected nonunion of phalangeal neck fractures of the thumb that were sustained in early childhood. Cosmetically, the affected thumb was shorter and smaller than the contralateral thumb. The thumb tip was flail and thumb pinch was weak. X-rays showed a nonunited phalangeal neck fracture with no radiologic evidence of avascular necrosis of the phalangeal head. All patients underwent iliac crest bone grafting. Bone union was obtained in all patients. At final follow-up (mean, 9 months), all patients were satisfied with the cosmetic appearance of the thumb. The thumb length increased by an average of 6 mm (range, 5-8 mm). Pinch improved in the range of 69% to 87% of the power of the contralateral thumb. However, there was restricted range of motion of the interphalangeal joint (mean range of motion of 10 degree only). It was concluded that delayed bone grafting of neglected nonunions of pediatric phalangeal neck fractures of the thumb is a worthwhile procedure and has a high satisfaction rate.
