“…Paediatricians diagnosed deformities of the foot in 614 of these infants and referred them to the paediatric orthopaedic clinic as part of a screening programme for DDH. The senior author (RWP) examined all the hips clinically using the Barlow and Ortolani tests 11 and ultrasonographically using Harcke's dynamic [12][13][14] and modified Graf's static morphological methods. [15][16][17] A simplified Graf classification was used in which a Graf angle of over 60° was classified as normal (type I), of 43° to 60° as type II, and below 43°a nd stable as type III.…”

“…2 We hypothesize that the ossific nucleus of the femoral head in young children is visible on plain radiographs and can be used as a reference to find the CFH. However, the ossification CFH can be eccentric, and it cannot be used to determine the CFH.…”

Determination of the center of the femoral head (CFH) may be difficult because of incomplete epiphyseal ossification of the femoral head in children younger than 8 years. The purpose of this study is to find a practical method for determining the center of the femoral head in normal hips of children younger than 8 years. Twenty-seven children who had magnetic resonance imaging (MRI) examinations of their hips (N = 54) were reviewed retrospectively. The average age of the subjects was 4.7 years (range, 1.2-8 years). Measurements were performed on the closest section to the midcoronal plane of the femoral head (the widest spherical femoral head seen on the MRI section). The CFH on the MRI section was found using a constructed circular frame by using a computer program. The medial and lateral edges of the proximal femoral ossific nucleus were marked, and the midpoint of the ossific nucleus adjacent to the growth plate (MPON) was determined. The distance between the MPON and the CFH was calculated. The average distance was 1.5 mm (range, 0-5 mm). The distance between these 2 points was less than or equal to 2 mm in 40 hips (74%). In conclusion, this study shows that the MPON can be used as a landmark to determine the center of the femoral head in normal hips of children younger than 8 years and can be used to measure the lower extremity mechanical axis.

“…4 children with teratological dislocations were excluded from this analysis. All 247 children were treated with the von Rosen splint for 6 weeks, after which the hips were re-examined clinically and with sonography using an anterior dynamic technique (Harcke et al 1984, Dahlström et al 1986, Harcke and Grissom 1990, Harcke 1992. If the displacement of the femoral head exceeded one quarter of its diameter, measured by sonography, the hip was diagnosed as being unstable.…”

Background There is no concensus on the optimal treatment time for unstable hips in the newborn. We analyzed the efficiency of a treatment program that has been used for 10 years at our hospital, in which all unstable hips (subluxatable, Barlow-positive and Ortolani-positive) are treated with the von Rosen splint for 6 weeks.Patients and methods Between 1988 and 1997, 32,171 children were born alive at the hospital. During this period 247 children had a clinically unstable hip diagnosed. 223 of the 247 children underwent a radiographic follow-up after 5-15 years.Results 1 patient with bilateral instability and treated with a splint for 6 weeks showed a dislocated left hip at the radiographic examination at 8 months, which is part of the screening program, and needed operative treatment. 1 patient did not follow the treatment program and showed a dislocated hip at the age of 3. Another 4 patients required more treatment than the 6 weeks with the splint.We found no dysplastic hips at the radiographic follow-up. There was no late dysplasia and there were no late dislocations in children born in Lund between 1988 and 1997 who were diagnosed at other Swedish centers that treat developmental dysplasia of the hip (DDH).Interpretation We conclude that the present screening and 6-week treatment in a von Rosen splint prevent almost all cases of late dysplasia and late dislocation of the hip.
