Key result
Pavlik harness treatment successfully relocated 97% of Graf type III dislocated hips compared to 50% of Graf type IV hips.
Why the study?
Does Pavlik harness treatment successfully relocate neonatal hip dislocations based on Graf's sonographic classification?
Cohort (n=40)
Does Pavlik harness treatment successfully relocate neonatal hip dislocations based on Graf's sonographic classification?
Absolute Event Rate: 97% vs 50%
Graf's sonographic classification has prognostic significance for the success of Pavlik harness treatment in neonatal hip dislocation, with significantly higher success in type III compared to type IV hips.
Graf type predicts Pavlik harness relocation rates; supports prognostic stratification yet leaves open need for randomized trials.
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.

Mostert et al. (2000) conducted a cohort in Neonatal hip dislocation (n=40). Graf type III classification vs. Graf type IV classification was evaluated on Successful dynamic relocation of the dislocated hip. Pavlik harness treatment successfully relocated 97% of Graf type III dislocated hips compared to 50% of Graf type IV hips.
