Abstract
BACKGROUND Blount disease can occur at any time during the growth process, primarily with a bimodal distribution in children younger than 4 years old and adolescents. The disease process most commonly presents in Black adolescents, with disease severity positively correlated with obesity. Given the known associations among race, obesity, and socioeconomic status, we investigated the relationship between the degree of social deprivation and severity of lower extremity deformities among a community-based cohort with Blount disease. METHODS A retrospective review of hospital records and radiographs of patients with previously untreated Blount disease was conducted. Patients were classified as having early-onset or late-onset Blount disease based on whether the lower limb deformity was noted before or after the age of 4 years. The area deprivation index (ADI), a nationally validated measure that assesses socioeconomic deprivation by residential neighborhood, was calculated for each patient as a surrogate for socioeconomic status. Higher state (range: 1 to 10) or national (range: 1 to 100) ADI corresponds to increased social deprivation. Full-length standing radiographs from index clinic visits were evaluated by 2 reviewers to measure frontal plane deformity. The association of ADI with various demographic and radiographic parameters was then analyzed. RESULTS Of the 65 patients with Blount disease, 48 (74%) children were Black and 17 (26%) were non-black children. Nineteen children (32 limbs) had early-onset and 46 children (62 limbs) had late-onset disease. Black patients had significantly higher mean state (7.6 vs. 5.4, P =0.009) and national (55.1 vs. 37.4, P =0.002) ADI values than non-black patients. Patients with severe socioeconomic deprivation had significantly greater mechanical axis deviation (66 mm vs. 51 mm, P =0.008). After controlling demographic and socioeconomic factors, the results of multivariate linear regression showed that only increased body mass index (β=0.19, 95% CI: 0.12-0.26, P <.001) and state ADI (β=0.021, 95% CI: 0.01-0.53, P =.043) were independently associated with greater varus deformity. CONCLUSIONS Socioeconomic deprivation was strongly associated with increased severity of varus deformity in children with late-onset Blount disease. Our analysis suggests that obesity and socioeconomic factors are the most influential with regard to disease progression. LEVEL OF EVIDENCE Level III.

Abstract
Legg-Calvé-Perthes disease (LCPD) and Blount's disease share a similar presenting age in addition to similar symptoms such as limp or knee pain. A little overlap is mentioned about both diseases. We sought to present cases of children having both conditions to discuss the implications of this co-occurrence on diagnosis and management. After institutional review board approval, we retrospectively reviewed records of four children who developed both Blount's disease and LCPD. Patient details and outcomes were analyzed. Radiographs were evaluated for the lateral pillar classification, Stulberg classification, tibial metaphyseal-diaphyseal angle and tibiofemoral angle. Two of the cases were initially diagnosed with Blount's disease and subsequently developed Perthes, one case presented initially with both disorders and the final case had Perthes followed by Blount's. Three children were obese and one was overweight. The common symptom to all patients was an abnormal gait, which was painless in two children and painful in two. Blount's disease required surgery in three children. Radiographs showed Lateral Pillar B, B/C border and C hips, and the final Stulberg was stage II (n = 2) or stage IV (n = 2). Obesity is associated with Blount's disease and LCPD, so obese children can be at an increased risk of developing both disorders. Therefore, a child with Blount's disease who has persistent, recurrent or worsening symptoms such as gait disturbance or thigh or knee pain might benefit from a careful physical exam of the hips to prevent a delayed or even missed LCPD diagnosis.

Abstract
BACKGROUND Cam morphology is thought to originate near puberty and reflects a response of the peripheral aspect of the proximal femoral physis to increased local load. Participation in particular sports activities has been associated with cam morphology in contemporary patient populations; however, it is unclear whether cam is a recent phenomenon. There are limited data regarding the frequency of its occurrence and the general deviations in femoral anatomy in different historical populations. Such information may help to understand the possible influence of lifestyle and diet on cam morphology. QUESTIONS/PURPOSES The purpose of this study was to evaluate femoral morphology in three historical populations. We asked: (1) Was cam morphology present in the three study populations, did those populations differ, and were there differences between sexes? (2) Were there differences in neck-shaft angle, version, or inclination between and among the examined populations? METHODS We examined 204 adult femurs from the Neolithic population from Iran (n = 37, 3000 BC to 1631 BC), medieval population from Poland (n = 135, 10th to 13th centuries), and contemporary Australian aborigines (n = 32, early 20th century), provided by the Open Research Scan Archive, Museum of the First Piasts at Lednica and the University of Wrocław, respectively. All three human populations represent different chronologic periods and lifestyles. All bones were scanned using CT and then measured on their three-dimensional (3-D) reconstructions in selected planes. Cam impingement was defined as an alpha angle > 55° measured on the inclination view. To evaluate the differences in anatomy between populations, we measured the true neck-shaft angle on the true AP view, apparent neck-shaft angle on the apparent AP view, the version angle on the version view, and the inclination angle on the inclination view. The prevalence of cam morphology and other anatomic parameters were compared among groups using chi-square test, one-way ANOVA with post hoc Tukey test, and paired t-test. RESULTS Cam morphology was present in 5% of the Neolithic population from Iran, in 7% of the medieval population from Poland, and 3% of the contemporary Australian aborigine femurs (OR Neolithic population from Iran/the medieval population from Poland 0.7 [95% CI 0.2 to 3.4]; p = 0.67; OR Neolithic population from Iran/contemporary Australian aborigines 1.8 [95% CI 0.2 to 20.5]; p = 0.65; OR the medieval population from Poland/contemporary Australian aborigines 2.5 [95% CI 0.3 to 20.1]; p = 0.40). There were differences in the presence of cam morphology between the sexes in the medieval population from Poland with both femurs (females: 1% [1 of 76]; males: 15% [9 of 59]; p = 0.002). There was a difference in true neck-shaft angle between the Neolithic population from Iran (121° ± 6°) and contemporary Australian aborigines (131° ± 5°; mean difference 10° [95% CI 7° to 13°]; p < 0.001) and between the medieval population from Poland (124° ± 5°) and the contemporary Australian aborigines (mean difference 7° [95% CI 5° to 9°]; p < 0.001). Apparent neck-shaft angle differed between the Neolithic population from Iran (126° ± 6°) and the contemporary Australian aborigines (134° ± 5°; mean difference 8° [95% CI 6° to 11°]; p < 0.001), and between the medieval population from Poland (126° ± 6°) and the contemporary Australian aborigines (mean difference 9° [95% CI 7° to 11°]; p < 0.001). Moreover, we observed a difference in the version angle between the Neolithic population from Iran (19° ± 7°) and the medieval population from Poland (12° ± 9°; mean difference 7° [95% CI 4° to 10°]; p < 0.001] and in the inclination angle between aforementioned groups (18° ± 7° versus 11° ± 8°; mean difference 7° [95% CI 5° to 10°]; p < 0.001). CONCLUSION This study found that cam morphology existed in historical populations at rates comparable with a contemporary population. CLINICAL RELEVANCE The presence of cam morphology in historical populations suggests that cam morphology can develop outside of the intense sports activity seen in modern adolescents. Further study will help elucidate the etiology of cam morphology, which may be useful in the development of preventive strategies.

Abstract
OBJECTIVE To examine associations between birth defects and cancer from birth into adulthood. DESIGN Population based nested case-control study. SETTING Nationwide health registries in Denmark, Finland, Norway, and Sweden. PARTICIPANTS 62 295 cancer cases (0-46 years) and 724 542 frequency matched controls (matched on country and birth year), born between 1967 and 2014. MAIN OUTCOME MEASURES Relative risk of cancer in relation to major birth defects, estimated as odds ratios with 99% confidence intervals from logistic regression models. RESULTS Altogether, 3.5% (2160/62 295) of cases and 2.2% (15 826/724 542) of controls were born with major birth defects. The odds ratio of cancer for people with major birth defects compared with those without was 1.74 (99% confidence interval 1.63 to 1.84). For individuals with non-chromosomal birth defects, the odds ratio of cancer was 1.54 (1.44 to 1.64); for those with chromosomal anomalies, the odds ratio was 5.53 (4.67 to 6.54). Many structural birth defects were associated with later cancer in the same organ system or anatomical location, such as defects of the eye, nervous system, and urinary organs. The odds ratio of cancer increased with number of defects and decreased with age, for both non-chromosomal and chromosomal anomalies. The odds ratio of cancer in people with any non-chromosomal birth defect was lower in adults (≥20 years: 1.21, 1.09 to 1.33) than in adolescents (15-19 years: 1.58, 1.31 to 1.90) and children (0-14 years: 2.03, 1.85 to 2.23). The relative overall cancer risk among adults with chromosomal anomalies was markedly reduced from 11.3 (9.35 to 13.8) in children to 1.50 (1.01 to 2.24). Among adults, skeletal dysplasia (odds ratio 3.54, 1.54 to 8.15), nervous system defects (1.76, 1.16 to 2.65), chromosomal anomalies (1.50, 1.01 to 2.24), genital organs defects (1.43, 1.14 to 1.78), and congenital heart defects (1.28, 1.02 to 1.59) were associated with overall cancer risk. CONCLUSIONS The increased risk of cancer in individuals with birth defects persisted into adulthood, both for non-chromosomal and chromosomal anomalies. Further studies on the molecular mechanisms involved are warranted.

Abstract
BACKGROUND Ultrarare Marshall-Smith and Malan syndromes, caused by changes of the gene nuclear factor I X (NFIX), are characterised by intellectual disability (ID) and behavioural problems, although questions remain. Here, development and behaviour are studied and compared in a cross-sectional study, and results are presented with genetic findings. METHODS Behavioural phenotypes are compared of eight individuals with Marshall-Smith syndrome (three male individuals) and seven with Malan syndrome (four male individuals). Long-term follow-up assessment of cognition and adaptive behaviour was possible in three individuals with Marshall-Smith syndrome. RESULTS Marshall-Smith syndrome individuals have more severe ID, less adaptive behaviour, more impaired speech and less reciprocal interaction compared with individuals with Malan syndrome. Sensory processing difficulties occur in both syndromes. Follow-up measurement of cognition and adaptive behaviour in Marshall-Smith syndrome shows different individual learning curves over time. CONCLUSIONS Results show significant between and within syndrome variability. Different NFIX variants underlie distinct clinical phenotypes leading to separate entities. Cognitive, adaptive and sensory impairments are common in both syndromes and increase the risk of challenging behaviour. This study highlights the value of considering behaviour within developmental and environmental context. To improve quality of life, adaptations to environment and treatment are suggested to create a better person-environment fit.

Abstract
OBJECTIVE The ubiquity of cribra orbitalia in skeletal samples has led to rigorous debate over their etiology, with most concluding that nutrition, physiological stressors, and environmental disease vectors synergistically contribute to lesion development. To parse the relative contributions of these etiological factors in the prehistoric Andes, this spatial paleopathological meta-analysis investigates the relationship between population-wide prehistoric Andean cribra orbitalia rates and geographic, climatic, and hydrological variables. METHODS Crude prevalence patterns of cribra orbitalia from 61 archaeological sites were plotted and analyzed with geostatistical methods to explore spatial patterns in the distribution of anemia-associated lesions. Multiple linear regression modeling was performed on 19 spatial variables suspected to contribute to various forms of anemia that result in cribrotic lesions. RESULTS Spatially-clustered high cribra orbitalia rates exist around the Central Peruvian coast, but are paradoxically low on the Ecuadorian coast. Multiple regression shows that elevation, temperature, and precipitation were not predictive of lesion rates. Multiple regression models show that aridity and seasonal variability in freshwater supply, together, explained a third of the variation in lesion rates. CONCLUSION While cribra orbitalia has long been tied to coastal proximity, these results suggest environmental constraints such as the need for water storage could have promoted malnutrition and pathogenic infection more than mere coastal proximity. LIMITATIONS OF THIS STUDY This analysis is limited by the paucity of data from highland sites and by the assumption that burials are local to the excavation site. SUGGESTIONS FOR FUTURE RESEARCH Future studies will integrate isotopic and remotely-sensed data into models to explore links between water security, nutrition, and disease.

Abstract
Background: The role of the ‘clicky hip’ symptom as a prognostic predictor of developmental dysplasia of hip (DDH) is controversial. We aim to study the role of isolated hip clicks as a prognostic predictor of DDH. Material and methods: 235 babits with persisting or referred with clicky hip beyond six weeks of age were prospectively followed up to note the incidence of DDH. Of these 176 babies were referred for a hip click without additional risk factors. Results: 7 out of 176 cases (4 - IIa, 2 - IIb, 1 - IIc) had initial abnormal ultrasound examination based on Graf classification. However, all babies with isolated hip clicks eventually had normal hips on clinical and radiographic examination. Discussion: While screening of babies with clicky hips does help in diagnosing the odd case of DDH this is not consistently reproducible. Modifying the targeted ultrasound screening by including clicky hip as a risk factor will not reduce the incidence of missed cases. Isolated clicks in the hip joint beyond six weeks age are rarely a predictor of DDH. However when in doubt such cases should be referred to be reviewed by an orthopaedic surgeon or a radiologist experienced in hip ultrasound.

Abstract
ABSTRACT:Background:To date, few pediatric series of neurofibromatosis type 1 (NF-1) have been described in the literature even though it is the most frequently encountered phakomatosis.Methods:We reviewed 987 charts of pediatric patients with a presumptive diagnosis of NF-1 who were evaluated at Ste-Justine hospital from January 1, 1991 to July 31, 2002. Patients who presented with two or more cardinal criteria were diagnosed with NF-1. Clinical and laboratory data were retrospectively collected, including: demographics, neuroimaging and presence or absence of associated symptoms or signs of NF-1.Results:A total of 279 patients were diagnosed with NF-1. The mean age at diagnosis was 3.4 years. Ninety-nine percent of the patients had café au lait spots and 47% had a first degree relative with NF-1. Almost 60 percent (59.6%) of those seen by an ophthalmologist had Lisch nodules. Optic glioma was found in in 14.7%, cutaneous neurofibromas in 38.4%, plexiform neurofibromas in 24.7%, neurofibrosarcoma in 1.8%, learning disabilities in 39%, attention deficit disorder in 40.5%, osseous dysplasias in 7.2%, pseudoarthrosis in 3.6%, precocious puberty in 3.2% and short stature in 17.9%. Magnetic resonance, when performed, showed hyperintense T2 lesions in 87.1% of cases. The mean period of follow-up was 7.4 years.Conclusion:Neurofibromatosis type 1 is a multisystemic disorder associated with increased risk of malignancy. It can be diagnosed at a very young age and clinical follow-up is advised. To our knowledge, this is the largest single center study of NF-1 in a pediatric population.

Abstract
OBJECTIVE To epidemiologically characterize the population treated at our orthopedic clinic with a diagnosis of septic arthritic of the hip between 2006 and 2012. METHODS Fifteen patients diagnosed with septic arthritis of the hip between 2006 and 2012 were retrospectively evaluated. The patients' clinical and epidemiological characteristics were surveyed; a sensitivity profile relating to the microorganisms that caused the infections and the complications relating to the patients' treatment and evolution were identified. RESULTS Septic arthritis was more common among males. Most diagnoses were made through positive synovial fluid cultures, after joint drainage was performed using the Smith-Petersen route. Among the comorbidities found, the most prevalent were systemic arterial hypertension, diabetes mellitus, and human immunodeficiency virus. The pathological joint conditions diagnosed prior to joint infection were osteoarthrosis and developmental dysplasia of the hip. The infectious agent most frequently isolated was Staphylococcus aureus. From the clinical and laboratory data investigated, 53.33% of the cases presented with fever, and all except one patient presented with increased measures in inflammation tests. Gram staining was positive in only 26.66% of the synovial fluid samples analyzed. Six patients presented with joint complications after treatment was administered. CONCLUSION S. aureus is the most common pathogen in acute infections of the hip in our setting. Factors such as clinical comorbidities are associated with septic arthritis of the hip. Because of the relatively small number of patients, given that this is a condition of low prevalence, there was no statistically significant correlation in relation to worse prognosis for the disease.

Abstract
OBJECTIVE To assess the prevalence of skeletal dysplasias (SDs) in patients with idiopathic short stature (ISS) or small for gestational age (SGA) status. SETTING Rare Endocrine/Growth Diseases Center in Paris, France. DESIGN A prospective study on consecutive patients with ISS and SGA enrolled from 2004 to 2009. METHOD We used a standardized workup to classify patients into well-established diagnostic categories. Of 713 patients with ISS (n=417) or SGA status (n=296), 50.9% underwent a skeletal survey. We chose patients labeled normal or with a prepubertal slowdown of growth as a comparison group. RESULTS Diagnoses were ISS (16.9%), SGA (13.5%), normal growth (24.5%), transient growth rate slowing (17.3%), endocrine dysfunction (12%), genetic syndrome (8.9%), chronic disease (5.1%), and known SD (1.8%). SD was found in 20.9% of SGA and 21.8% ISS patients and in only 13.2% in our comparison group. SD prevalence was significantly higher in the ISS group than in the comparison group, especially (50%) for patients having at least one parent whose height was <-2 SDS. Dyschondrosteosis and hypochondroplasia were the most frequently identified SD, and genetic anomaly was found in 61.5 and 30% respectively. Subtle SD was found equally in the three groups and require long-term growth follow-up to evaluate the impact on final height. CONCLUSION SD may explain more than 20% of cases of growth retardation ascribed to ISS or SGA, and this proportion is higher when parental height is <-2 SDS. A skeletal survey should be obtained in patients with delayed growth in a context of ISS or SGA.

Abstract
CONCLUSION Otologic and audiologic abnormalities are both highly prevalent in Chinese children with skeletal dysplasias. Audiologic and otologic evaluations with medical intervention are recommended for these children. OBJECTIVE Children with skeletal dysplasia have a number of otolaryngologic issues including hearing loss. This study aimed to investigate the otologic and audiologic features of Chinese children with skeletal dysplasia in central China. METHODS Otologic evaluations and pure tone audiometry were performed in children with skeletal dysplasias. To explore the potential associations with hearing loss, we studied various craniofacial anomalies. RESULTS A total of 125 children (mean age 9.2 years, range 5-18 years) with skeletal dysplasia were enrolled, and otoscopic examination identified eardrum abnormalities in 45.6% of the children. Audiologic analysis revealed 14 cases (11.2%) with conductive hearing loss (CHL) and 22 cases (17.6%) with sensorineural hearing loss (SNHL).

Abstract
BACKGROUND The congenital orthopaedic anomalies in Thai population had a limited data and the previously studies are based on only hospital chart records. OBJECTIVE To determine the incidence of common congenital orthopedic problems by physical examination in newborn at Siriraj Hospital. MATERIAL AND METHOD A prospective study was conducted by physical examination of 3,396 newborns from June 2009 to September 2009. All orthopaedic abnormalities of newborns were recorded along with maternal age, obstetric history of mother, complications during pregnancy, complications in labour stage, mode of delivery and presentation. Sex of newborn, birth weight, body length and APGAR score were recorded. RESULTS Incidence of calcaneovalgus was found in 60:1,000 live births following by metatarsus adductus in 7.6:1,000, polydactyly or syndactyly in 2.6:1,000, talipes equninovarus in 2.4:1,000, brachial plexus injury in 1.5:1,000, developmental dysplasia of hip in 0.6:1,000, osteogenesis imperfecta in 0.6:1,000, skeketal dysplasia in 0.6:1,000, congenital vertical talus in 0.3: 1,000 and fracture clavicle at birth in 0.3: 1,000. CONCLUSION In the present study, the calcaneovalgus was the most common orthopaedic problem followed by metatasus adductus, polydactyly or syndactyly.

Abstract
SUMMARY High bone mineral density on routine dual energy X-ray absorptiometry (DXA) may indicate an underlying skeletal dysplasia. Two hundred fifty-eight individuals with unexplained high bone mass (HBM), 236 relatives (41% with HBM) and 58 spouses were studied. Cases could not float, had mandible enlargement, extra bone, broad frames, larger shoe sizes and increased body mass index (BMI). HBM cases may harbour an underlying genetic disorder. INTRODUCTION High bone mineral density is a sporadic incidental finding on routine DXA scanning of apparently asymptomatic individuals. Such individuals may have an underlying skeletal dysplasia, as seen in LRP5 mutations. We aimed to characterize unexplained HBM and determine the potential for an underlying skeletal dysplasia. METHODS Two hundred fifty-eight individuals with unexplained HBM (defined as L1 Z-score ≥ +3.2 plus total hip Z-score ≥ +1.2, or total hip Z-score ≥ +3.2) were recruited from 15 UK centres, by screening 335,115 DXA scans. Unexplained HBM affected 0.181% of DXA scans. Next 236 relatives were recruited of whom 94 (41%) had HBM (defined as L1 Z-score + total hip Z-score ≥ +3.2). Fifty-eight spouses were also recruited together with the unaffected relatives as controls. Phenotypes of cases and controls, obtained from clinical assessment, were compared using random-effects linear and logistic regression models, clustered by family, adjusted for confounders, including age and sex. RESULTS Individuals with unexplained HBM had an excess of sinking when swimming (7.11 [3.65, 13.84], p < 0.001; adjusted odds ratio with 95% confidence interval shown), mandible enlargement (4.16 [2.34, 7.39], p < 0.001), extra bone at tendon/ligament insertions (2.07 [1.13, 3.78], p = 0.018) and broad frame (3.55 [2.12, 5.95], p < 0.001). HBM cases also had a larger shoe size (mean difference 0.4 [0.1, 0.7] UK sizes, p = 0.009) and increased BMI (mean difference 2.2 [1.3, 3.1] kg/m(2), p < 0.001). CONCLUSION Individuals with unexplained HBM have an excess of clinical characteristics associated with skeletal dysplasia and their relatives are commonly affected, suggesting many may harbour an underlying genetic disorder affecting bone mass.

Abstract
Mucopolysaccharidosis I Hurler (MPS IH) is a progressive multisystemic disorder caused by alpha-L-iduronidase deficiency. First choice of treatment in MPS IH children is haematopoietic stem cell transplantation (HSCT). The effect of HSCT has been shown to have limited influence on skeletal manifestations by poor penetration of musculoskeletal tissues by the enzyme derived from donor leucocytes. Aim of this study was to investigate the effect of HSCT on the craniocervical junction (CCJ) in Hurler patients. We analysed retrospectively sequential magnetic resonance imaging (MRI) scans of 30 patients with Hurler disease treated by HSCT since 1982 at the Royal Manchester Children's Hospital, UK, in order to determine whether the patients suffer from dens hypoplasia. Results were compared with biochemical and clinical characteristics: Enzyme activity (EA), chimerism, urinary glycosaminoglycan (GAG) excretion and neurological status. Investigations were part of standard clinical procedures. Results are descriptive in presentation. In 26/30 patients a determination of odontoid hypoplasia was feasible. The majority showed a normal dens length and an increase with age. Only 3/26 revealed a dens hypoplasia. One of them had only partial donor engraftment (DE) with reduced EA, one of them suffered from chronic graft versus host disease (GVHD). One patient with only partial DE and reduced EA presented with initial dens hypoplasia until preadolescence but normalized later on. There may be a trend towards lower EA and the occurrence of DH in transplanted MPS patients - perhaps the dosage of enzyme plays a role in the correction of skeletal complications in this patient group. HSCT patients with incomplete DE and therefore lower EAs may require special attention and care.

Abstract
BACKGROUND Hunter disease is a rare X-linked mucopolysaccharidosis. Despite frequent neurological involvement, characterizing the severe phenotype, neuroimaging studies are scarce. OBJECTIVES To determine frequency and severity of neuroradiological mucopolysaccharidosis-related features; to correlate them with clinical phenotype; to evaluate their natural evolution and the impact of intravenous enzymatic replacement therapy (ERT). METHODS Sixty nine brain MRI examinations of 36 Italian patients (mean-age 10.4 years; age-range 2.2-30.8; severe phenotype in 22 patients) were evaluated. Twenty patients had multiple MRIs (median follow-up 3.1 years, range 1-16.9): among them 15 had MRIs before and after ERT, six had repeated MRIs without being on ERT and five while on ERT. Perivascular, subarachnoid and ventricle space enlargement, white matter abnormality (WMA) burden, pituitary sella/skull/posterior fossa abnormalities, periodontoid thickening, spinal stenosis, dens hypoplasia, myelopathy, vertebral and intervertebral disc abnormalities were graded by means of dedicated scales. RESULTS Perivascular spaces enlargement (89%), WMAs (97%), subarachnoid space enlargement (83%), IIIrd-ventricle dilatation (100%), pituitary sella abnormalities (80%), cranial hyperostosis (19%), craniosynostosis (19%), enlarged cisterna magna (39%), dens hypoplasia (66%), periodontoid thickening (94%), spinal stenosis (46%), platyspondylia (84%) and disc abnormalities (79%) were frequently detected. WMAs, IIIrd-ventricle dilatation and hyperostosis correlated with the severe phenotype (p < 0.05). Subarachnoid spaces and ventricle enlargement, WMAs and spinal stenosis progressed despite ERT, while other MR features showed minimal or no changes. CONCLUSIONS The spectrum of brain and spine MRI abnormalities in Hunter disease is extremely wide and requires a thorough evaluation. WMAs, atrophy/communicating hydrocephalus and spinal stenosis progress over time and might represent possible disease severity markers for new treatment efficacy assessment.

Abstract
Obesity and premature adrenarche (PA) are both associated with bone age (BA) advancement of unclear etiology, which may lead to earlier puberty, suboptimal final height and obesity in adulthood. Our objective was to understand the hormonal and anthropometric characteristics of BA advancement in a spectrum of prepubertal children with and without obesity and PA. In this cross-sectional study of 66 prepubertal children (35 PA, 31 control, 5-9 years), BMI z-score, hormonal values and response to an oral glucose tolerance test were the main outcome measures. Subjects were divided into tertiles by BA divided by chronological age (BA/CA), an index of BA advancement. Subjects in the top tertile for BA/CA had the highest dehydroepiandrosterone sulfate (DHEAS), free testosterone (%), hemoglobin A(1C), BMI z-score, and weight (P < 0.05). BMI z-score (r = 0.47), weight (r = 0.40), free testosterone (%) (r = 0.34), and DHEAS (r = 0.30) correlated with BA/CA (P < 0.02). Regression analysis showed greater BA/CA in PA compared to controls after controlling for weight (0.21 ± 0.56, P < 0.004). An exploratory stepwise regression model showed that weight, estradiol, and DHEAS were the strongest predictors of BA/CA accounting for 24% of its variance. Obesity was highly associated with BA advancement in this study of prepubertal children. In addition, children with PA had greater BA/CA at any given weight when compared to controls. These findings suggest a possible hormonal factor, which potentiates the effect of obesity on BA advancement in children with obesity and/or PA.

Abstract
PURPOSE OF REVIEW To assess factors that influence the tempo of bone mass accrual with emphasis on obesity, exercise, and nutritional factors. RECENT FINDINGS The prevalence of childhood obesity has increased dramatically throughout the world. Recent studies suggest that adiposity may be detrimental to development of bone strength parameters, and bone mass accrual during growth. Weight-bearing exercise during prepubertal and peripubertal period appears to enhance bone strength parameters. Maternal ultraviolet B radiation exposure and vitamin D status has been shown to have a positive effect on neonatal bone status, which appears to track up to the prepubertal period. Administration of vitamin D with or without calcium, but not calcium alone, during the prepubertal period might be an important 'window' for improving skeletal mineralization. SUMMARY Obesity in children appears to be detrimental to development of bone strength parameters and bone mass accrual. Weight-bearing exercise during prepubertal and peripubertal period and vitamin D supplementation during pregnancy, infancy, and peripubertal period might be important for bone mass accrual. However, adequately powered randomized controlled trials with follow-up into adulthood are needed to determine if these interventions improve the tempo of bone mass accrual.

Abstract
Late-onset tibia vara or Blount's disease is the most common cause of pathologic genu varum in children and adolescents. Treatment remains controversial. Many studies in the past have shown that an osteotomy with acute correction is the most appropriate treatment. More recently however, there has been a growing interest, especially in severe cases, in using gradual correction with the Ilizarov technique after a single high tibial osteotomy. A retrospective study in 20 children with late-onset tibia vara, who were treated by gradual angulation translation high tibial osteotomy using the Ilizarov technique, was performed. The mean follow-up period was 2.9 years (range: 2-4 years; SD 0.75). Recurrence of varus deformity to various degrees was noted in 10 of 22 cases (45.5%). Recurrence of deformity was found to be significantly related to both the degree of pre-operative deviation and the duration of follow-up. No statistically significant relationship was found between recurrence and the age of the patients at the time of the operation. Angulation translation high tibial osteotomy using the Ilizarov technique is a unique method for realignment of the mechanical axis in late onset tibia vara. It also allows for correction of associated deformities. The rate of recurrence of varus deformity is however relatively high.

Abstract
OBJECTIVE Radiographic parameters used to define acetabular dysplasia may be related to anthropological characteristics independent of dysplasia. The goal of the present study was to investigate the relationship between the minimal joint space width (JSW) of the hip and the parameters that define acetabular dysplasia, in clinically normal subjects. DESIGN One hundred and eighteen patients who underwent supine abdominal radiography for non-rheumatological indications and had no hip pain or history of hip arthritis were evaluated. JSW was quantified manually using dial calipers, and center edge (CE) angle and acetabular depth were measured for each hip. RESULTS CE angle, but not acetabular depth, correlated (inversely) with the minimal hip JSW (r=-0.26 and -0.20, P=0.005 and 0.038, R (right) and L (left) hips, respectively). CE angle inversely correlated with the pelvic width (r=-0.27 and 0.27, P=0.003 and 0.004, R and L hips, respectively) and acetabular depth correlated with subject's height (r=0.27 and 0.42, P=0.008 and <0.001 R and L hips, respectively) and leg length (r=0.27 and 0.45, P=0.008 and <0.001, R and L hips, respectively). Also, pelvic width correlated significantly with the JSW (r=0.27 and 0.20, P=0.003 and 0.033, for R and L hips, respectively). CONCLUSIONS The radiographic parameters used to define acetabular dysplasia, CE angle and acetabular depth, are strongly associated with anthropological variables and CE angle is associated with minimal JSW of the hip. It is important to recognize that height and limb length variability may affect radiographic parameters of acetabular dysplasia, and thus may falsely suggest the presence of anatomic abnormalities in some patients.

Abstract
Child growth constitutes a very sensitive indicator for the assessment of their health state. Any deviation from standard parameters could entail the appearance of any congenital or acquired disorder. Identifying with precision children's bone age during their growth period can be very useful in different situations. From a clinical point of view, it is a tool for diagnosis, which can offer the possibility of monitoring treatment effects in the case of standard deviations. This is why we need to study in depth current methods and carry out regular controls that insure their reliability. Currently, the most frequent radiological methods in our country for the determination of children's bone age were designed in the middle of the 20th century on the basis of X-rays performed on children from other countries. Thus, it would be interesting to find out whether social, economic, nutritional and health changes in Spain have influenced child growth and development in a significant way. Hence it would invalidate traditional methods for the determination of bone age. This study came from a main hypothesis: the child's environment significantly influences the concordance of bone age and chronological age. Our aim was to study a possible relationship between nutrition and bone development. Thus, the fastest way of testing this hypothesis was to implement a cross-sectional prevalence study in order to determine the percentage of children showing a chronological age concording with bone age. The study was entirely carried out in the Traumatology Hospital of Granada, which belongs to the University Hospital Virgen de las Nieves. We used the information provided by the Emergency Department about slight traumatisms. The cross-section sample was adapted to our main hypothesis. The overall number of patients was 100, which exceeds the necessary cases to test the reliability of this particular study. On the other hand, in order to determine the concordance of bone age and its different variables, an analitical study was also carried out, which includes: an univariant analysis, a bivariate analysis and a multivariate analysis, with the various tests they usually include. We found out that children showing a delayed bone age eat less bread than those showing an advanced bone age. It would be necessary to determine whether bone age and bone mass have inversely related values before considering it as concordant information. We could only determine that, currently, advanced bone maturation is usually associated with rapid growth. It is possible that children who eat more bread actually show an advanced bone age, a more rapid growth and a reduced bone mass. However, in this study, the outcomes must be considered just as preliminar, due to the size of the cross-section sample. Our research on the influence of nutrition should also include a further longitudinal study.

Abstract
OBJECTIVE To investigate and compare the usefulness of preoperative magnetic resonance (MR) imaging and high-resolution temporal bone computed tomography (HRCT) in pediatric cochlear implant candidates. STUDY DESIGN Prospective. SETTING Tertiary referral center. PATIENTS A cohort of 92 pediatric patients with profound hearing. Inclusion criteria were MR, computed tomography, and cochlear implantation. INTERVENTION. DIAGNOSTIC All patients had preoperative imaging of the petrous temporal bone (HRCT, T2-weighted fast spin echo, axial 3D Fast Imaging Employing Steady-state Acquisition [FIESTA] MR) and brain (Fast Fluid-attenuated Inversion-recovery [FLAIR] MR). MAIN OUTCOME MEASURE(S) Overall prevalence of inner ear dysplasias in this population and comparison of detection rates between HRCT, T2 Fast Spin Echo (FSE), and FIESTA MR sequences. RESULTS Radiological abnormalities were observed in 32 and 59% of MR and HRCT temporal bone, respectively. Synchronous intracranial findings were noted in 40% on brain MR. Common vestibulocochlear nerve was observed in 3% ears and directed side of implantation. Consistent discrepancies noted on HRCT were inability to diagnose early obliterative labyrinthitis and presence of the cochlear nerve in the internal auditory canal. With respect to MR, enlarged vestibular aqueducts and narrow cochlear nerve canals were consistently under identified. CONCLUSION Dual-modality imaging with HRCT and MR of petrous bone and MR brain in the precochlear implant pediatric population detects abnormalities related to deafness, which would not otherwise be found using either modality alone. There is overlap between the imaging modalities in the type of abnormalities detected, and we present a case for selective use of HRCT within a diagnostic algorithm, using the patient risk factors we have identified.

Abstract
Distinctive risk factors for disease are identifiable throughout life stages of large- and giant-breed dogs. From weaning to maturity, improper nutrition is linked to developmental skeletal diseases. As large dogs mature, skeletal diseases and obesity can lead to osteoarthritis. These dogs are difficult to manage when orthopedic or osteoarthritic disease affects mobility and quality of life, thereby increasing the risk of early death. Gastric dilatation and volvulus is another disease that is leading cause of death in large- and giant-breed dogs. Management of health, including proper nutrition, exercise, and weight control, provides the best opportunity for successful aging of large- and giant-breed dogs.

Abstract
OBJECTIVES We investigated hip rotation degrees, frequency of intoeing problems, and sitting habits in nursery school children and the relationship between these parameters. METHODS The study included 1,134 children (612 boys, 522 girls), aged between three to six years, attending 26 nursery schools in the central area of Afyon. First, informed consent was obtained from the parents and a questionnaire was administered about demographic data and sitting habits of the children. Then, the children were examined in lower underwear. Foot progression angles were determined and progression to midline during walking was evaluated as intoeing. Internal and external rotation degrees of the hips were measured using a goniometer in prone and supine positions. RESULTS In girls, internal rotation of the hip was nearly 13 degrees greater in the prone position, and 9 degrees greater in the supine position compared to those of the boys. Intoeing was detected in 67 children (5.9%), 76.1% being bilateral. The girl-to-boy ratio was 2.4/1. Intoeing problem originated from the femur in 74.6%, and from the tibia in 25.4%. Compared to normal children, intoeing was associated with a greater internal rotation and a smaller external rotation of the hip. Overall, 36.7% had a crossed-leg sitting habit, and 63.3% had a television sitting habit. The latter was more frequent in intoeing children (p=0.001). CONCLUSION Although hip rotation degrees in our study were similar to those reported in the literature, higher hip internal rotation degrees were found especially in girls. Television sitting which is a frequently preferred position among nursery school children was significantly prevalent in intoeing children.

Abstract
As the increasing prevalence of overweight and obese children is approaching epidemic proportions in North America, this study was designed to investigate whether Body Mass Index (BMI) and age- and gender-specific percentile Body Mass Index (BMI %) are associated with the likelihood of being listed for surgery for Blount disease after initial presentation to a tertiary referral centre. In a restrospective consecutive sample of 102 children with an average age of 5.9 +/- 4.3 years, it was determined that there was a significant association between BMI and BMI% and being listed for surgery, after adjusting for the effects of the child's age and gender, with mean odds ratios of 1.30 (95% confidence interval 1.02-1.60) and 1.05 (95% confidence interval 1.01-1.09) respectively. When the sample was subgrouped into infantile (less than 3 years of age) and late-onset (greater than 3 years of age), BMI and BMI% were still significantly associated with the children being listed for surgery in the late-onset group with mean odds ratios 2.75 (95% confidence interval 1.03-7.33) and 1.09 (95% confidence interval 1.01-1.18) respectively. However, of the two measures only the BMI was significant in the infantile group with an odds ratio of 1.27 (95% confidence interval 1.01-1.60). Should these associations be real then measures aimed at decreasing weight in children may have some effect on the number of children undergoing surgery for the treatment of Blount disease.

Abstract
The purpose of this study was to evaluate the effect of type 2 growth disturbances in the developing hip and compare it with other treated hips without evidence of growth arrest. Radiographic data of 117 children (155 hips) with late developmental dislocation of the hip treated by closed reduction at an average age of 14.9 months and followed to skeletal maturity were retrospectively reviewed. Depending on the presence of lateral growth disturbances, our patients were divided into 2 groups similar with regard to age and treatment methods. Lateral physeal arrest was evident at an average age of 8.9 years in 23% of these hips. Seventy-six percent of these hips with type 2 avascular necrosis were classified as Severin classes 1 and 2. One quarter of them had no deformity of femoral head, 8 had deformity of 2 mm or less, and 18 more than 2 mm. There was no statistical difference in satisfactory and unsatisfactory results or most parameters describing the acetabulum between the 2 groups. Lateral tilting of the proximal femoral epiphysis in most cases does not affect final radiologic results. It is a mild form of avascular necrosis and indications for secondary operative procedures are mostly related to natural history of the disease rather than to lateral physeal arrest.

Abstract
OBJECTIVE Little is known about the interactions of sports-related demands and human body, in particular on musculoskeletal features, during growth. Focusing on the relationship between soccer and lower limb alignment, we examined the hypothesis that varus knee deviation is more prevalent among high-performance pediatric and adolescent soccer players. DESIGN Cross-sectional study with focused sampling. SETTING First league sports clubs. PARTICIPANTS 106 male child/adolescent soccer players aged 10 to 21 years and 68 age-matched tennis players. INTERVENTIONS All athletes completed a demographic questionnaire and underwent physical examinations, which included height, weight, generalized laxity, knee, ankle, foot and spine axis, hip range of motion, tibial torsion, Q angle, foot navicular height, and progression angle. MAIN OUTCOME MEASUREMENT Varus/valgus axis was determined by the intercondylar intermalleolar distance while standing. Soccer and tennis players were compared on knee axis and other outcome variables by analysis of covariance, adjusting for age and by t-tests within age groups. RESULTS A significantly higher prevalence of knee varus was found among the soccer players compared to that among the tennis players. The difference in intracondylar distance was statistically significant after the age of 13 years (P < 0.001). In addition, compared to tennis players, soccer players had higher foot arches, decreased hip external rotation and increased external tibial torsion. CONCLUSIONS Varus knee axis deviation was more common among children and adolescent soccer players than among tennis players. The prevalence was more pronounced among players aged 13 years or older. Further research is needed to explore the rationale of this phenomenon.

Abstract
The treatment of spinal deformities in children with myelomeningocele poses a formidable task. Multiple medical comorbidities, such as insensate skin and chronic urinary tract infection, make care of the spine difficult. A thorough understanding of the natural history of these deformities is mandatory for appropriate treatment to be rendered. A team approach that includes physicians from multiple specialties provides the best care for these patients. The two most challenging problems are paralytic scoliosis and rigid lumbar kyphosis. The precise indications for surgical intervention are multifactorial, and the proposed benefits must be weighed against the potential risks. Newer spinal constructs now allow for fixation of the spine in areas previously difficult to instrument. Complications appear to be decreasing with improved understanding of the pathophysiology associated with myelomeningocele.

Abstract
Despite the fact that ultrasound of children's hips is widely used for screening, late diagnosed cases of developmental dislocation of the hip are still a common problem in the orthopaedic practice. The aim of the study is to review final clinical and radiological outcomes of treatment of DDH with overhead traction and closed reduction after skeletal growth. Clinical records and radiograms of 107 hips (81 children) were retrospectively reviewed. All of them were treated according to the same program: overhead traction (about 2 weeks), followed by closed reduction, modified Lorenz cast (2 months) and finally cast in Lange position (3 months). Average age of children was 14.2 months at the beginning of treatment and 20.7 years at last visit. Good and very good results were found in 80% of cases according to final radiological assessment of Severin and in 91% according functional classification of Harris. Avascular necrosis of femoral head according to Bucholz-Ogden classification system was identified in one third of patients. Functional results are better than radiological, but deteriorated with time especially in hips with residual dysplasia and AVN due to development of early, secondary degenerative changes.

Abstract
Prader-Willi syndrome (PWS) is characterized by hypotonia, obesity, hypogonadism, small hands and feet, and mental deficiency. Obesity and hypogonadism are also frequently associated with slipped capital femoral epiphysis (SCFE), suggesting that children with PWS might be at increased risk of developing SCFE. Members of the Prader-Willi Syndrome Association (U.S.A.) were surveyed regarding the history of orthopaedic problems in general and of SCFE in particular. A total of 565 (63%) responses were received. The prevalence of orthopaedic conditions included 47% with flat feet, 41% with scoliosis, 19% with knock knees, 10% with hip dysplasia, 9% with osteoporosis, 7% with patellofemoral instability, 3% with bowlegs, 2% each with clubfeet, nursemaid's elbow, or leg-length inequality, and one patient (0.2%) with SCFE. The results of the survey indicate that SCFE is uncommon in patients with PWS, but the prevalence of hip dysplasia is increased approximately 10-fold compared with the general population.

Abstract
The prevalence of hip osteoarthritis (OA) varies with different regions, and the reasons for this remain unclear. Mild acetabular dysplasia has been considered a risk factor for hip OA, but recent studies have not confirmed this. In Turkey, the prevalence of significant radiographic hip OA, i.e. Kellgren-Lawrence (K-L) grades 3 and 4, is lower than in Western populations. We aimed to investigate the potential effects of radiographic measures of acetabular dysplasia on this discrepancy. Ninety-two Turkish patients (65 males, 27 females) aged 55 and over were studied. Plain supine abdominal radiographs and intravenous pyelographs were evaluated. Centre-edge (CE) angle and acetabular depth (AD) of each hip were measured, and K-L grading was done. The mean CE angles +/- SD of right and left hips were 34+/-7 degrees and 35+/-7 degrees (range 14-52 and 18-50), respectively. The mean AD+/-SD of right and left hips was 13.7+/-3.4 and 13.6+/-3.4 (range 6-23 and 8-25), respectively. Mean CE angle or acetabular depth of the hips with K-L grade 2 did not differ from those with grades 0 and 1. There was no patient with grade 3 or 4. The prevalence of acetabular dysplasia based on a CE angle of <25 degrees was 9.8% in both right and left hips. When it was defined as having an AD of <9 mm, the prevalence was 4.3% and 1.1% in the right and left hips, respectively. Overall, 10.4% of the hips (13% of the men and 3.7% of the women) had acetabular dysplasia based on at least one of these measurements. Mild acetabular dysplasia appears to be relatively common among Turks aged 55 and over. However, it does not seem to play a major role in the development of radiographic hip OA.

Abstract
The aim of the study was to assess the possible existence of major genes influencing hip and elbow dysplasia in four dog populations. A Bayesian segregation analysis was performed separately on each population. In total, 34 140 dogs were included in the data set. Data were analysed with both a polygenic and a mixed inheritance model. Polygenic models included fixed and random environmental effects and additive genetic effects. To apply mixed inheritance models, the effect of a major gene was added to the polygenic models. The major gene was modelled as an autosomal biallelic locus with Mendelian transmission probabilities. Gibbs sampling and a Monte Carlo Markov Chain algorithm were used. The goodness-of-fit of the different models were compared using the residual sum-of-squares. The existence of a major gene was considered likely for hip dysplasia in all the breeds and for elbow dysplasia in one breed. Several procedures were followed to exclude the possible false detection of major genes based on non-normality of data: permuted datasets were analysed, data-transformations were applied, and residuals were judged for normality. Allelic effects at the major gene locus showed nearly to complete dominance, with a recessive, unfavourable allele in both traits. Relatively high estimates of the frequencies of unfavourable alleles in each breed suggest that considerable genetic progress would be possible by selection against major genes. However, the major genes that are possibly affecting hip and elbow dysplasia in these populations will require further study.

Abstract
BACKGROUND Many young adults with cancer of good prognosis seek advice from their doctors, because they are concerned about their ability to have children and about potential hereditary diseases in the children conceived or fathered after cancer therapy. PATIENTS AND METHODS Results of repeated examinations of 61 children over a period of 20 years are reported. One of their parents had received radiotherapy for malignant disease (only three had additional chemotherapy). Radiation doses to the gonads ranged from 0.01 to 2 Gy. The most frequent indications for radiotherapy were Hodgkin's disease (n=25), seminomas (n=7), thyroid cancer (n=3), and malignant melanomas (n=3) RESULTS There was a trend to premature birth with 52.5% of the babies born before term. Yet, all had normal birth weight and delivery was inconspicuous. The skeletal maturation was retarded, but development was still in the normal range of German children. There were no chromosome aberrations, normal mental and intellectual development, and no malignancy among these children. A trend to an increased frequency of developmental disturbances and four moderately severe malformations were observed; however, no direct association with radiation treatment could be demonstrated. One child had a balanced translocation (5;17) which it inherited from the unirradiated parent. CONCLUSION During the first consultation of young adult cancer patients, before the start of treatment, the problems of fertility and of therapy-induced mutations and hereditary diseases as well as developmental damage of the offspring need to be addressed directly by the radiation oncologist. Decisions on cryoconservation of sperm, fixation of the ovaries and dosimetry of the gonads during radiotherapy have to be made before the start of treatment. The rate of radiation-induced hereditary diseases and developmental damage in the children conceived or fathered after curative radiotherapy of one parent is estimated to increase by <0.1% (after gonadal exposure of 1 Gy). However, at present, heritable damage potentially induced by chemotherapy cannot be adequately quantified yet.

Abstract
Tibial osteotomies in children have been associated with a number of complications. A retrospective review of 116 children who had 129 tibial osteotomies was performed to assess these complications at our institution. Results showed that there were 35 cases of wound problems, 6 cases of recurrence/reoperation, 5 cases of delayed union, 2 cases with transient peroneal nerve palsy, 1 case of nonunion, and 1 case of mal-union. Patients having certain comorbidities had a higher frequency of complications. There were no significant differences between the location of the tibial osteotomy (proximal or distal) and the incidence of complication. External fixation was associated with a lower incidence of complications than the use of pins and casting. Although our results demonstrate an overall low complication rate, there is a significant association between complications and comorbid conditions. This highlights the need to recognize comorbidities preoperatively and the potential of increased postoperative complications.

A large-scale epidemiological study was conducted to determine breeds at risk for 12 developmental orthopedic diseases (DODs). Developmental orthopedic diseases investigated included canine hip dysplasia (CHD); craniomandibular osteopathy (CMO); fragmented coronoid process; hypertrophic osteodystrophy; Legg-Calvé-Perthes disease; osteochondrosis of the medial humeral condyle, caudal humeral head, femoral condyles, and talar trochlear ridges; panosteitis; patella luxation; and ununited anconeal process. Dogs that were diagnosed with any one of the diseases of interest at any of 10 veterinary teaching hospitals participating in the Veterinary Medical Database from 1986 to 1995 were included as cases. Odds ratios and corresponding 95% confidence intervals were calculated to determine risk. Frequency of diagnosis during the 10-year period ranged from 35 cases (CMO) to 10,637 cases (CHD). The number of breeds at increased risk for a disease ranged from one (CMO) to 35 (CHD). Breed susceptibility for a DOD may suggest a genetic component in the disease etiology. The results of this study serve to increase veterinarians' awareness of breeds susceptible to DODs and may facilitate the control of such diseases by identifying breeds that might benefit from breeding programs or environmental intervention such as dietary modification.

Abstract
PURPOSE OF THE STUDY Developmental lumbar stenosis is a rare entity, exceptionally described in the literature. No study has been directly devoted to this condition. The purpose of the present study was to examine specific features, particularly clinical and anatomic expression, observed in a series of operated patients. MATERIAL AND METHODS Eleven patients from the French Antilles were treated for developmental lumbar stenosis between 1996 and 2000. The Verbiest criteria were used to define canal narrowness. Signs of degeneration and presence of discal herniation were exclusion criteria. Epidemiological and clinical data were collected for the 11 patients. The degree of sagittal stenosis (fixed diameter at the bone level and mobile diameter at the discal level) was measured on computed tomography images. Transverse stenosis was determined by measuring the interpedicular and interapophyseal distances. Lateral stenosis was determined by measuring the depth of the recessus. RESULTS These patients were young (mean age 42.4 years). Most of the clinical signs were monoradicular. Discal level stenosis predominated, generally at level L4-L5. It was generally central and lateral, sagittal and transverse. The interpedicular distance was the only diameter that remained within normal limits. Soft tissues (yellow ligaments and joint capsules) played an important role in the stenosis. DISCUSSION The rare reports of developmental lumbar stenosis describe decompensated stenosis due to discal herniation in the adolescent. Developmental lumbar stenosis is considered to be a genetic disease and its particular high frequency in the French Antilles favors this hypothesis. The stenosis results from bony (short pedicles, hypertrophic lateral masses) and ligament (hypertrophy of the yellow ligament and joint capsules) structures. CONCLUSION Developmental lumbar stenosis produces a global (sagittal, transverse, central, lateral) narrowing of the lumbar canal where soft tissue structures apparently play a greater role than usually thought. A prospective study examining the impact of ethnic origin is required to analyze the genetic hypothesis.

Abstract
OBJECTIVE To characterize the features and prevalence of radiographic abnormalities of the wrist in children with Kashin-Beck disease (KBD) and to determine whether the presence of radiographic abnormalities in the wrist correlates with the severity of KBD. DESIGN AND PATIENTS Two hundred and eight posteroanterior radiographs of the right hand (including wrist) in children with KBD, ranging in age from 4 to 11 years (mean age 7.7 years), from endemic areas of China were reviewed. Carpal bony margins were evaluated for blurring, thinning, irregularity with and without sclerosis, interruption, depression or destruction. The radiocarpal, intercarpal and carpometacarpal joints were assessed for widening or narrowing. The severity of the disease was graded using the hand criteria from the Chinese Radiographic Criteria of KBD Diagnosis, which classifies the following five types according to the location of the hand involved: I, metaphysis; II, diaphysis; III, I+II; IV, metaphysis and epiphysis; V, II+IV. RESULTS Of the 208 children, 95 had abnormalities in the hand but not in the wrist; 108 had both hand and wrist abnormalities; only five had abnormal wrist findings without any hand abnormalities. Of the 108 cases with wrist abnormalities, all the carpal bones were involved in 33 cases, of which the hand types were either IV or V. However, any individual carpal bone, or combination of bones, may become involved. The carpal bones most likely to show abnormalities were the capitate and the hamate (93%), followed by the triquetrum (31%), the lunate (9%), the scaphoid (6%), and the trapezoid and the trapezium (5%). The pisiform bones were not evaluated because they cannot be seen on the overlapping posteroanterior radiographs. The most commonly involved carpal joint was the midcarpal joint (42%). CONCLUSIONS Recognizing carpal abnormalities on radiographs is helpful for the diagnosis of KBD and the evaluation of the severity of the disease. The more severe the KBD, the more likely that the carpal bones will be involved. The capitate and hamate are frequently affected if the disease involves the carpal bones.

Abstract
INTRODUCTION Mental retardation (MR) constitutes a clinical and social relevant condition accounting for 3% of the pediatric population. Studies focusing the repercussion of MR on nutritional status are scarce and, in occasions, have produced contradictory results. OBJECTIVE To evaluate the nutritional status of mentally retarded children in our Region, on the basis of skeletal maturation. PATIENTS AND METHODS Our sample comprise 128 mentally retarded children (81 boys and 47 girls) aged 0 17 years. In all children a nutritional and social family environment questionnaires and a valuation of a series of nutritional and anthropometric variables were performed. Additionally, bone age was assessed by means of left hand wrist radiograph in a subset of 53 children. A factorial analysis was carried out by means of the statistical package SPSS allowing the obtaining of 2 anthropometric factors and 3 biochemical factors that condensed the most information content. Results of the bone maturation were correlated with age, sex, presence of cerebral palsy (CP), severity of mental retardation, results of nutritional and sociofamilial questionnaire, antiepileptic treatment and nutritional status (anthropometric and biochemical factors). RESULTS Although a good correlation exists between bone age and chronological age, 50% of mentally retarded children presented delay in their skeletal maturation. The bone maturation was higher in the boys than in the girls. The presence of CP induced an increase of 12% in the delay of the skeletal maturation. The severity of MR induced differences in the bone age. Both quality of diet and score of anthropometric factor I inversely correlated with bone maturation delay. Parent s age and geographical precedence but not antiepileptic therapy affected the bone maturation. CONCLUSIONS Delay in the bone maturation occurs with high prevalence among mentally retarded children. The presence of CP, severity of MR, quality of the diet and sociofamilial and nutritional factors influenced in an outstanding way in the bone maturation.

Abstract
STUDY DESIGN Predictive correlational study. OBJECTIVES To identify the incidence of medial tibial stress syndrome (MTSS) in a group of high school cross-country runners and to determine if a relationship exists between lower extremity structural measures and the incidence of MTSS. BACKGROUND Medial tibial stress syndrome is an overuse injury that occurs in long-distance runners. Literature exists that implicates structural deformity as a contributor to MTSS, but no studies have developed a predictive model. METHODS AND MEASURES We measured 125 high school cross-country runners for tibiofibular varum, resting calcaneal position during stance, and gastrocnemius length. Runners developing MTSS over an 8-week period were placed in the injured group (2 men, 13 women; age 15.3 years 1.0), and 21 randomly selected uninjured runners were placed in the uninjured group (13 men, 8 women; age 15.7 years +/-1.5). Navicular drop was measured for runners in both groups. Reliability of measures was determined using an intraclass correlation coefficient (ICC 3,1). Paired t tests were used to compare the injury and noninjury groups. A logistic regression analysis was used to establish if the descriptive data could accurately predict the development of MTSS. RESULTS Paired t tests showed a significant difference in navicular drop test measures between the injured (6.8 mm 3.7) and noninjured (3.6 mm 3.3) groups. Logistic regression analysis revealed navicular drop test measurements and sex correctly identified athletes who developed MTSS with 76% accuracy. CONCLUSION Our study supported the hypothesis that a pronatory foot type is related to MTSS. The combination of sex and navicular drop test measures provides an accurate prediction for the development of MTSS. Clinical measures that identify biomechanical risk factors for MTSS may allow prevention or early intervention.

Abstract
The bibliographic research online is an useful means of recovering information in all the subjects, particularly in the field of biomedicine. In fact, this instrument allows researchers to get information in a rapid, complete and up-to-date way. The aim of the present review is to describe the usefulness of the bibliographical research online in the field of the genetic osteopathies. These are rare disorders: so, their own rarity makes the bibliographical research online necessary to carry out a large and effective comparison of experiences. The obtained results are amply reported in the manuscript. For instance, we verified that chondrodysplasias are the diseases most represented in the literature, while melorheostosis the disorder less mentioned. Moreover, we evidenced that some hereditary disorders of connective tissue, such as Marfan's syndrome, osteogenesis imperfecta and Ehlers-Danlos syndrome, are strongly influenced by race, sex and age.

Abstract
Clinical and histopathological similarities and rare association of Blount's disease with various proximal femoral physeal affections (i.e. adolescent coxa vara and slipped capital femoral epiphysis) are well known. Association of tibia vara with another epiphyseal disease of the proximal femur has not been reported previously. In this paper, a monozygotic set of twins with concordant bilateral epiphyseal growth disturbance of the proximal femur and unilateral late-onset tibia vara is presented. Radiological characteristics of the affected knees revealed a wedging in the proximal tibial epiphysis, depression of the medial joint surface and varus deformity of the tibia. Proximal femurs of both cases showed aspheric congruity, coxa magna, shortness of the femoral neck, and subchondral cystic changes. The presented cases support the genetic etiology of tibia vara, and association of the two conditions is unique.

Abstract
Premature closure of the capital femoral physis after pin fixation of slipped capital femoral epiphysis (SCFE) in the juvenile population (at least 1 year less than the established mean) can lead to growth disturbances of the proximal femur. A retrospective review of 21 patients (33 hips) who had a pinning of a juvenile SCFE was performed. Growth disturbances including greater trochanteric overgrowth, coxa vara, and coxa breva were noted in 64% of the hips. An 80% incidence of bilateral involvement was noted in the juvenile group. Consideration should be given to prophylactic pinning of the contralateral hip and use of a smooth pin construct to prevent premature closure of the growth plate in children with significant growth remaining.

Abstract
Early radiographic screening and/or referral to a clinical specialist are often used to distinguish between physiologic bow leg deformity and infantile tibia vara disease in young children. These practices are a consequence of the clinician's inability (based upon the clinical examination) to distinguish between the deformities associated with physiologic and pathologic bow legs. Because the great majority of these children have physiologic bowing, routine radiographic screening and referral are not cost effective and expose children to unnecessary radiation. This study describes and evaluates the efficacy of a simple clinical examination technique, the 'cover up' test, to identify young children with bow legs who are at high risk for having infantile tibia vara. The 'cover up' test qualitatively assesses the alignment of the proximal portion of the shank or lower leg relative to the thigh or upper leg. Obvious valgus alignment is considered a negative test and is indicative of physiologic bowing. Neutral or varus alignment is considered a positive test and suggests that the child is at greater risk for having infantile tibia vara. Eighteen children with infantile tibia vara, evaluated initially prior to 3 years of age, and followed to the time of surgical correction, were compared with 50 children with physiologic bowing, also evaluated initially prior to 3 years of age and followed to resolution (mean follow-up 3 years and 10 months). All of the children with infantile tibia vara had a positive 'cover up' test (sensitivity = 1.00). Eighteen of 25 children with a positive 'cover up' test actually had or developed infantile tibia vara (positive predictive value = 0.72). Forty-three of 50 children with physiologic bowing had a negative 'cover up' test (specificity = 0.86). All of the children with a negative 'cover up' test actually had physiologic bowing (negative predictive value = 1.00). We conclude that the 'cover up' test is an effective screening tool for the assessment of bow legs in children between 1 and 3 years of age. Children with a negative 'cover up' test do not require radiographic evaluation and should be followed clinically for resolution of the bowing. Children with a positive 'cover up' test should have radiographic evaluation of the lower extremities or be referred to a specialist for further evaluation and treatment.

Abstract
OBJECTIVE : To determine ethnic variations of acetabular morphology, and to delineate their relationship with hip osteoarthritis (OA). METHODS : Radiographs of 283 French men, 118 French women, 414 Japanese men and 368 Japanese women, aged 20-79 yr, who underwent intravenous urography were assessed by a single observer for morphometric measurement and hip OA scoring. RESULTS : The standardized morbidity ratio (SMR) for hip OA was highest in French men and lowest in Japanese men, whereas the SMR for acetabular dysplasia was highest in Japanese women and lowest in French men. French men and women had the highest centre-edge angle, followed by Japanese men then Japanese women. CONCLUSION : In a large number of subjects assessed by a single observer, this study confirms other previous reports that the relationship between acetabular dysplasia and risk of hip OA is negative.

Abstract
Data from 2,764 Rottweiler dogs born from 1987 to 1996 were analyzed with a Restricted Maximum Likelihood procedure using a mixed linear animal model to obtain variance component estimates for hip and elbow dysplasia. The data included 2,764 hip dysplasia and 2,278 elbow dysplasia records. Hip joints were scored as normal (0), borderline (1), slight (2), moderate (3), and severe (4, 4.5, and 5) hip dysplasia. Elbow joints were graded normal or borderline (0), slight (1), moderate (2), and severe (3) elbow dysplasia. The mean for the hip scores was 1.07 and for the elbow scores .60. Environmental effects influencing hip dysplasia were age, birth year, birth year x season interaction, and experience of the veterinarian responsible for x-raying the dog. For elbow dysplasia, statistically significant effects were age, birth year, sex of the dog, and panelist responsible for each screening. Estimates of heritability for hip and elbow dysplasia were .58 +/- .04 and .31 +/- .04, respectively, with a genetic correlation of .37 +/- .08 between the traits. Genetic improvement of almost one genetic standard deviation was observed in both traits during the 10 yr covered by the data.

Abstract
OBJECTIVES With the use of clinical data from a large international cohort, we evaluated and compared affected siblings and isolated cases. STUDY DESIGN Data from 116 families were collected, and patients conforming to our predetermined diagnostic criteria were analyzed. Phenotypic manifestations of affected siblings and singletons were compared with the use of t tests, Wilcoxon scores, and chi2 analysis. RESULTS Eighty-eight patients (33 female, 55 male; median age 5.20 years) fulfilled our predetermined diagnostic criteria for Shwachman syndrome; 63 patients were isolated cases, and 25 affected siblings were from 12 multiplex families. Steatorrhea was present in 86% (57 of 66), and 91% (78 of 86) displayed a low serum trypsinogen concentration. Patients older than 4 years more often had pancreatic sufficiency. Neutropenia occurred in 98%, anemia in 42%, and thrombocytopenia in 34%. Myelodysplasia or cytogenetic abnormalities were reported in 7 patients. Short stature with normal nutritional status was a prominent feature. CONCLUSIONS Clinical features among patients with Shwachman syndrome varied between patients and with age. Similarities in phenotype between isolated cases and affected sibling sets support the hypothesis that Shwachman syndrome is a single disease entity.

Abstract
Epidemiological studies during 1963-1997 were conducted in 45,725 children exposed to high intake of endemic fluoride in the drinking water since their birth. Children with adequate (dietary calcium > 800 mg/d) and inadequate (dietary calcium < 300 mg/d) calcium nutrition and with comparable intakes of fluoride (mean 9.5 +/- 1.9 mg/d) were compared. The toxic-effects of fluoride were severe and more complex and the incidence of metabolic bone disease (rickets, osteoporosis. PTH bone disease) and bony leg deformities (genu valgum, genu varum, bowing, rotational and wind-swept) was greater (> 90%) in children with calcium deficiency as compared to < 25% in children with adequate calcium who largely had osteosclerotic form of skeletal fluorosis with minimal secondary hyperparathyroidism. The syndrome of skeletal fluorosis and associated metabolic bone disease and deformity is a unique clinical entity classified as a variant of osteosclerotic form of skeletal fluorosis. This syndrome chiefly results from the biological impact of excess fluoride, low calcium, high PTH and 1,25 (OH)2D3 separately and through their interactions on bone structure and metabolism as studied by radiology, bone scanning, bone histomorphometry and relevant metabolic and endocrine laboratory investigations. Metabolically active and vascular bones of children accumulate fluoride at faster and greater rate than adults (at the sites of active growth). In calcium deficient children the toxic effects of fluoride manifest even at marginally high (> 2.5 mg/d) exposures to fluoride. Fluoride toxicity also exaggerates the metabolic effects of calcium deficiency on bone. The findings strongly suggest that children with calcium deficiency rickets reported in the literature should be re-investigated for possible fluoride interactions. Deep bore drinking water supply with fluoride < 0.5 ppm and improvement of calcium nutrition provide 100% protection against the toxic effects of fluoride and are recommended as the cost effective and practical public health measures for the prevention and control of endemic fluorosis.

Abstract
OBJECTIVE To report examples of disorders characterized by bone fragility, calvarial and/or gnathic fibro-osseous lesions, and metadiaphyseal undermodeling of the tubular bones. DESIGN The clinical, radiological, and pathological features of two patients are described and the literature reviewed. PATIENTS The patients comprised a 10-year-old boy and a 48-year-old woman. The former exhibited multiple fractures starting in early childhood and calvarial masses which developed in late childhood; the latter showed a mandibular mass. RESULTS Calvarial doughnut lesions, osteopenia with coarse bony trabeculae, and undermodeling of the lower limbs were radiologically demonstrated in the first patient, while multiple sclerotic foci in the maxilla and mandible, spontaneous bowing of the right femur, and minimal undermodeling of the tibiae were demonstrated in the second. Bone biopsy of the iliac crest in the first patient revealed histologically normal bony trabeculae. Bone histomorphometry suggested an increased osteoid surface. Osteoid volume was also slightly increased. The pathological findings of the mass in the jaw in the latter patient were consistent with it being a fibro-osseous lesion. The literature review revealed several patients whose features overlapped with those of our patients. CONCLUSION These patients may represent a group of fragile bone syndromes which differ from osteogenesis imperfecta.

Abstract
A hospital based study of skeletal dysplasias was conducted over a period of 2 years in Davangere, Karnataka, in which 169 cases of skeletal dysplasias were studied. One hundred were osteochondrodysplasias and were grouped according to international classification of osteochondrodysplasias. Among the individual cases, osteogenesis imperfecta (13 cases) had the maximum representation. Several cases of rare disorders were also identified. Eighty eight cases of skeletal dysplasias were in the pediatric age group and of these 41 were newborns. The incidence of skeletal dysplasia among newborns was 19.6 per 10,000 deliveries and lethal dysplasias 5.2 per 10,000 deliveries. In 7 cases of skeletal dysplasia, an antenatal diagnosis was possible by ultrasonography.
