Results of Pavlik Harness Treatment for Neonatal Hip Dislocation as Related to Graf's Sonographic Classification

Abstract

In this prospective study, 41 dislocated hips in 40 patients were classified according to Graf's sonographic classification. Of them, 29 hips were Graf type III and 12 hips Graf type IV. All were treated in a Pavlik harness to relocate the dislocated hip dynamically. In type III hips, this was successful in 97% and 50% in type IV hips. We conclude that Graf's classification in dislocated hips has prognostic significance in treatment with the Pavlik harness.
