O2573 MANAGEMENT OF DEVELOPMENTAL DYSPLASIA OF HIP WITH THE PAVLIK HARNESS AND ULTRASOUND MONITORING



Abstract

Aims: This study shows the efþcacy of The Pavlik harness for the treatment of Development Dysplasia of hip (DDH) using ultrasonographic monitoring. Methods: Between 1995–2000 we treated 149 dysplastic hips in 117 babies. According to the Grafñs classiþcation 90 were dysplastic type IIB, IIC, IID hips; 59 were dislocated Type IIIA, IIIB and IV hips. Babies were regularly monitored using ultrasound unto 26 weeks and radiographs up to 5 years in dislocated hips for bony roof angle. Results: The average full time harness treatment was 12.2 (range 6–20) weeks, average follow up was 55 (range 30–90) months. The harness failed to reduce 14 hips (9.5% of total hips). Two cases continue to show a small femoral ossiþc nuclei at 30 months follow up. The hips showed no signiþcant difference in acetabular index from the normal values at follow up radiographs. Conclusions: We conclude that using this protocol, successful initial treatment of DDH with the Pavlik harness appears to restore normal development of the hip.
