Why the study?
What are the long-term outcomes of secondary open reduction in patients with failed primary open reduction for congenital dislocation of the hip?
What are the long-term outcomes of secondary open reduction in patients with failed primary open reduction for congenital dislocation of the hip?
Secondary open reduction for failed congenital hip dislocation is technically difficult and associated with high rates of femoral head necrosis and radiographic deformity, though some patients achieve functional recovery.

High necrosis rates after secondary open reduction for failed congenital hip dislocation warrant caution; leaves open optimal salvage strategies.
Fourteen patients with 15 congenital dislocated hips with unsuccessful open reduction were referred for a secondary open reduction. All primary open reductions were incomplete due to an inadequate exposure and insufficient release of muscles and ligaments. The secondary open reduction was technically difficult. The patients were followed for 6-17 years. Six patients had no functional symptoms. Only three hips showed no radiographic deformity. In ten hips, femoral head necrosis was noted and two patients were left with shortening of 4 and 7 cm.
