- Aim: To present normative dual energy X-ray absorptiometry data in healthy young Swedes. Methods: Included were 710 girls and 759 boys aged 6-30 years from southern Sweden. Bone mineral content, bone mineral density, bone size, lean body and fat mass were measured by dual energy X-ray absorptiometry in total body, lumbar spine, hip, arms and legs. Results: Swedish children had similar bone mass to children in the Netherlands but higher than children in Canada and Korea. Height, weight, bone mass, bone size and lean mass increased at a constant rate from age 6 until the rapid increase in all traits at puberty. The pubertal growth spurt started earlier in girls than in boys, while the spurt in boys was larger in magnitude and occurred for a longer period. Around one-quarter of the adult total body and lumbar spine peak bone mineral content was gained during the 2 years with the fastest gain in both genders. Conclusion: This study presents normative bone mass data in Swedish children, data that are similar to that in Dutch children but higher than in Canadian and Korean children. The gain in Swedish children seems to mimic the gain seen in children in other settings.

- AIM: To analyse factors associated with fractures in children with cerebral palsy (CP) in different levels of Gross Motor Function Classification System (GMFCS). METHOD: This was an epidemiological retrospective study of a total population of 536 children (214 females, 322 males) with CP born between 1990 and 2005. CP type was unilateral spastic (n=159), bilateral spastic (n=225), ataxic (n=60), dyskinetic (n=80), and mixed type (n=12); 384 children were in Gross Motor Function Classification Scale (GMFCS) levels I-III and 152 children were in GMFCS levels IV-V. Data were collected for a 9-year period on sex, CP-type, GMFCS level, gastrostomy, height, weight, the use of a standing device, antiepileptic drug (AED) therapy, and fractures. RESULTS: The risk of fracture in the total population of children with CP was similar to that for typically developing children. The risk for fractures of those in GMFCS levels I-III was not significantly associated with any of the studied risk factors. The risk of fractures for those in GMFCS levels IV-V on AED therapy was a twofold increase (p=0.004). The risk for fractures without trauma in children with stunted growth (height for age <-3 SD) and those who did not use standing devices was significantly increased: adjusted incidence rate ratio (AIRR) 4.16 (p=0.011) and 3.66 (p=0.010) respectively. Results regarding gastrostomy feeding for those in GMFCS levels IV-V were conflicting: a gastrostomy was associated with a reduced risk of fractures with trauma, but with increased risk of fractures without trauma (AIRR 0.10, p=0.003 and 4.36, p=0.012) respectively. INTERPRETATION: Children in GMFCS levels I-III had a similar incidence and pattern for fractures as normally developing children. Those in GMFCS levels IV-V had stunted growth, often a sign of longstanding undernourishment, and were associated with an increased risk of fractures. Children using standing devices had a fourfold reduction of fractures without trauma. Regular loading exercises and early adequate nutritional intake could prevent fractures in severe CP.

- Background and purpose As much as one-third of all total hip arthroplasties in patients younger than 60 years may be a consequence of developmental dysplasia of the hip (DDH). Screening and early treatment of neonatal instability of the hip (NIH) reduces the incidence of DDH. We examined the radiographic outcome at 1 year in children undergoing early treatment for NIH. Subjects and methods All children born in Malmö undergo neonatal screening for NIH, and any child with suspicion of instability is referred to our clinic. We reviewed the 1-year radiographs for infants who were referred from April 2002 through December 2007. Measurements of the acetabular index at 1 year were compared between neonatally dislocated, unstable, and stable hips. Results The incidence of NIH was 7 per 1,000 live births. The referral rate was 15 per 1,000. 82% of those treated were girls. The mean acetabular index was higher in dislocated hips (25.3, 95% CI: 24.6-26.0) than in neonatally stable hips (22.7, 95% CI: 22.3-23.2). Girls had a higher mean acetabular index than boys and left hips had a higher mean acetabular index than right hips, which is in accordance with previous findings. Interpretation Even in children who are diagnosed and treated perinatally, radiographic differences in acetabular shape remain at 1 year. To determine whether this is of clinical importance, longer follow-up will be required.
