Congenital clavicular pseudarthrosis: comparison of two treatment methods
Background:
Congenital pseudarthrosis of the clavicle is rare and popular surgical options include excision of the non-union, iliac crest bone grafting and stabilisation with either a fully threaded pin or stabilisation with a reconstruction plate.
Methods:
Between 1995 and 2009, ten patients with congenital pseudarthrosis of the clavicle were retrospectively reviewed for outcome of two different forms of surgical management. Five patients had excision of the non-union, iliac crest bone grafting and stabilisation with a fully threaded pin (group A) and the other five patients had excision of the non-union, iliac crest bone grafting and stabilisation with a reconstruction plate (group B). One patient in the second group had bilateral pseudarthrosis.
Results:
In group A, three patients achieved radiological union at a median of 6 months. Two patients failed to unite at the pseudarthrosis and one of them had further surgery with a reconstruction plate in order to achieve union. In group B, all five patients (six clavicles) achieved radiological union at a median of 3 months. All patients had painless full range of shoulder movement and were engaging in unrestricted activities.
Conclusion:
Excision of the pseudarthrosis, autogenous iliac bone grafting and stabilisation with plate achieves union quicker and with lower incidence of complications compared to excision of the pseudarthrosis, autogenous iliac bone grafting and stabilisation with fully threaded pins.
