Purpose of Study

To evaluate the results of using external fixation to stabilise femoral derotation osteotomy involved in DDH surgery.

Methods and results

A retrospective analysis was performed on 44 patients undergoing 48 femoral osteotomies for DDH surgery between the years 2001 and 2009 by a single surgeon (senior author MC). The external fixator was used either during the primary procedure involving femoral shortening to aid in hip reduction (4 patients) or to correct femoral malrotation in a reduced hip as a secondary procedure(40 patients). As the external fixator frame was within the hip spica it was not a cause of concern to the parents or the child.

There was no evidence of any pin tract infection and all patients eventually progressed to satisfactory bony union. One patient had delayed union which was treated successfully with conservative management and one patient had a malunion requiring a further osteotomy and extended treatment with the external fixator.
