Abstract: | The diagnosis and treatment of neonatal hip instability and dysplasia is controversial. Different countries have different algorithms and guidelines on which hips should be screened or treated. German speaking countries have introduced universal ultra sound hip screening programmes resulting in relatively high splintage rates in certain centres. Some Scandinavian centres have organised selective screening programmes with serial ultrasound observation of hip instabilities, leading to comparatively low splintage rates. Though most experts would treat clinical hip instability (confirmed by ultrasound evaluation), the natural history and epidemiology of dysplasia is less well understood. The treatment regimes for neonatal dysplasia are varied with wide differences in the rates of splintage. 'Late' dislocation may be secondary to prenatal dislocation (teratogenic), neonatal hip instability or to persistent major dysplasia of the hip. The term 'missed' dislocation should not be used as this suggests negligence on the part of the examiner, when this may not be the case. Which splint to use (rigid or dynamic), at what age, and for how long, are questions currently unresolved as no proper controlled trials have been undertaken. However, a sensible treatment algorithm can be advocated. Complications secondary to splintage are rare, though nerve damage, avascular necrosis of the hip, redislocation and skin problems have been described. |
