Abstract
CASE We present a 17-month-old girl with postencephalitic sequelae only on high-calorie cereal milk through a nasogastric tube. She presented with a 3-week history of swelling and decreased lower limb movements. Synovial fluid analysis ruled out septic arthritis. Plain radiograph and magnetic resonance imaging (MRI) were suggestive of scurvy. She was diagnosed to have pseudoparalysis secondary to scurvy. She was started on vitamin C supplements, after which she showed good clinical improvement. CONCLUSION This case report is to re-emphasize the need for awareness of the possibility of scurvy in children with poor nutritional status due to feeding difficulties.

Abstract
This study examined the 10-year trends in the prevalence of osteoporosis according to disability grade and type compared with those without disabilities in South Korea. We linked national disability registration data with the National Health Insurance claims data. Age- and sex-standardized prevalence of osteoporosis were analyzed from 2008 to 2017 according to sex, disability type, and disability grade. Adjusted odds ratios for osteoporosis according to disability characteristics in the most recent years' data were also confirmed by multivariate analysis. Over the past decade, the prevalence of osteoporosis has increased in people with disabilities compared with people without disabilities, and the gap has gradually widened from 7% to 15%. By analysis of the most recent year data, both male and female individuals with disabilities had a higher risk of osteoporosis than those without disability (odds ratios [OR] 1.72, 95% confidence interval [CI] 1.70-1.73 in males; OR 1.28, 95% CI 1.27-1.28 in females); the multivariate-adjusted OR was especially prominent in disability related to respiratory disease (OR 2.07, 95% CI 1.93-2.21 in males; OR 1.74; 95% CI 1.60-1.90 in females), epilepsy (OR 2.16, 95% CI 1.78-2.61 in males; OR 1.71; 95% CI 1.53-1.91 in females), and physical disability types (OR 2.09, 95% CI 2.06-2.21 in males; OR 1.70; 95% CI 1.69-1.71 in females). In conclusion, the prevalence and risk of osteoporosis have increased in people with disabilities in Korea. In particular, the risk of osteoporosis increases significantly in people with respiratory diseases, epilepsy, and physical disability types. © 2023 The Authors.

Closed displaced femur fractures in children with nonambulatory cerebral palsy. J Pediatr Orthop B 2022:01202412-990000000-00074.

Abstract
Femoral fractures in children withcerebral palsy (CP) represent a frequent medical problem, and treatment represents a challenge. The purpose of this study was to review the closed displaced femoral fractures in our population of nonambulatory children with CP to compare the results of nonoperative and operative treatment modalities to improve the care of these children. From 2006 to 2020, children with nonambulatory CP were selected with inclusion criteria of displaced femoral fracture and were divided into nonoperative and operative groups. Forty-four children met the inclusion criteria. The nonoperative group included 23 children and the operative group included 21 children. Mechanism of injury was unknown in 48% of the fractures. Fourteen (25%) fractures occurred after a femoral plate fixation during a reconstructive hip surgery, and 38 (86%) children had osteopenia. Our results reveal a high prevalence of osteopenia, low-energy trauma, malunion in nonoperative treatment, and peri-implant fractures. Suspicion of child abuse should be considered when the fracture has an unclear mechanism of the injury. Removal of proximal femoral implants may be considered to prevent peri-implant fractures. Femoral fractures should preferably be treated nonoperatively. Operative treatment should be considered for diaphyseal fractures in children capable of standing transfers, larger children, children with more severe spasticity or movement disorder or those who have suffered a high-energy fracture. Due to the high prevalence of proximal fractures in the presence of hardware, operative treatment is usually required for these fractures. In contrast, distal fractures are adequately managed nonoperatively.

Abstract
Children and adolescents with cerebral palsy (CP) are at increased risk of low trauma fractures (LTF) due to low bone mineral content (BMC). The risk of LTFs might be overestimated by only age - and sex adjusted Z-scores for BMC because Z-score based DXA techniques do not take into account other relevant parameters like height, muscle and fat mass. This study aimed to present an update of the functional muscle-bone unit-algorithm (uFMBU-A) to evaluate bone health in children with CP in order to predict the risk of LTF taking into account the parameters sex, age, height, muscle and fat mass. We performed a monocentric retrospective analysis of 177 DXA-scans of children and adolescents with CP aged 8-19. Six of these 177 patients had sustained at least 1 LTF. Age-, sex- and size adjusted Z-scores of total body less head (TBLH)-BMC, lean body mass and fat mass were calculated. The uFMBU-A was applied to the study group and results were compared with established Z-score based DXA-measurements and algorithm based diagnostic techniques concerning the prediction of LTF risk. The uFMBU-A had the greatest diagnostic odds ratio (13.3 [95% CI 2.41; 72.9]) of the evaluated predictors with a sensitivity of 50.0% (95% CI 11.8; 88.2), specifity of 93% (95% CI 88.1; 96.3). The uFMBU-A was the most accurate method of the evaluated parameters to predict LTF in children with CP and is recommended when evaluating bone health.

Abstract
The purpose of this review is to examine how whole-body vibration can be used as a tool in therapy to help improve common physical weaknesses in balance, bone density, gait, spasticity, and strength experienced by individuals with cerebral palsy. Cerebral palsy is the most common movement disorder in children, and whole-body vibration is quickly becoming a potential therapeutic tool with some advantages compared to traditional therapies for individuals with movement disorders. The advantages of whole-body vibration include less strain and risk of injury, more passive training activity, and reduced time to complete an effective therapeutic session, all of which are appealing for populations with physiological impairments that cause physical weakness, including individuals with cerebral palsy. This review involves a brief overview of cerebral palsy, whole-body vibration's influence on physical performance measures, its influence on physical performance in individuals with cerebral palsy, and then discusses the future directions of whole-body vibration therapy in the cerebral palsy population.

Abstract
PURPOSE To evaluate clinically relevant fracture characteristics by age, sex, and ambulatory status among individuals with cerebral palsy. METHODS Fracture location, energy of fracture, and activities that lead to a fracture were assessed among a clinic-based sample of children (0-17 years; n = 57) and adults (18-70 years; n = 58) with cerebral palsy that sustained a fracture by sex and gross motor function classification system (GMFCS) I-III vs. IV/V. RESULTS Proportion of fractures that were low-energy was 67-99% for children and 69-84% for adults. ∼2/3rds of fractures were at the lower extremities, with the distal femur being the most common site for children (44%) and the foot/ankle for adults (40%); however, there were age, sex, and ambulatory effects, such that 43% of adults GMFCS IV/V and 32% of women had a distal femur fracture. GMFCS I-III were more likely to fracture from functionally complex activities, while GMFCS IV/V were more likely to fracture from wheelchair/transfers/limb-stuck and incidental findings. CONCLUSIONS The majority of fractures were low-energy and occurred in the lower extremities, with effects by age, sex, and GMFCS. Activities that led to a fracture also differed by age and GMFCS, which can be used to design fracture prevention interventions in addition to bolstering skeletal mass and architecture.Implications for rehabilitationSkeletal fragility is a major problem for individuals with cerebral palsy (CP) across the lifespan leading to an increased risk of fragility fractures.Rehabilitation is a prime clinical intervention to prevent fractures from occurring and improving post-fracture healing and function; yet, effective rehabilitation interventions require knowledge of fracture characteristics, such as where fractures are occurring and the activities that lead to the fracture event specific to individuals with CP.Using a clinic-based sample of 0-70 year olds with CP, we describe salient fracture characteristics based on age, sex, and ambulatory status to enhance translation into clinical and rehabilitation practice.

Abstract
Objective To understand the relation of musculoskeletal strength and function to postural stability in ambulatory adults with cerebral palsy (CP) who have already developed muscle atrophy and osteoporosis. Design Two independent group comparison of adults with CP and those without it. Setting Laboratory study. Participants Thirteen adults with CP with sex (9 women: 4 men), age (21-62y), and Gross Motor Function Classification System I-III, and 13 sex-, age-, and body-weight-matched control participants completed our study (N=26). Intervention Not applicable. Main Outcome Measure Bone mineral density (BMD), structural or geometrical deformities (at the proximal region of the femur at the hip joint), and maximal muscular strength (forearm and thigh) were measured. The primary outcome measure was postural stability (balance measured using an automated balance system and a Berg Balance Test). Results Femoral BMD was significantly lower in the CP group compared to the control group, whereas BMD at lumbar and forearm regions was similar between groups. Geometrical angles, lengths, and diameters at the proximal femur were significantly lower in the CP group. There was a direct relation between BMD in the femoral neck and knee extension peak torque in the control group with no relation in the CP group. Although the control group did not show a relation between muscular strength and balance test, the CP group showed a significant linear relation among improving postural stability with greater levels of muscular strength. Conclusion There were structural differences at the proximal femur and muscular weakness in adults with CP. In adults with CP, balance appears to be more influenced by structural alterations at the femur than muscular strength compared to the control group.

Abstract
Cerebral Palsy (CP) describes a heterogenous group of non-progressive disorders of posture or movement, causing activity limitation, due to a lesion in the developing brain. CP is an umbrella term for a heterogenous condition and is, therefore, descriptive rather than a diagnosis. Each case requires detailed consideration of etiology. Our understanding of the underlying cause of CP has developed significantly, with areas such as inflammation, epigenetics and genetic susceptibility to subsequent insults providing new insights. Alongside this, there has been increasing recognition of the multi-organ dysfunction (MOD) associated with CP, in particular in children with higher levels of motor impairment. Therefore, CP should not be seen as an unchanging disorder caused by a solitary insult but rather, as a condition which evolves over time. Assessment of multi-organ function may help to prevent complications in later childhood or adulthood. It may also contribute to an improved understanding of the etiology and thus may have an implication in prevention, interventional methods and therapies. MOD in CP has not yet been quantified and a scoring system may prove useful in allowing advanced clinical planning and follow-up of children with CP. Additionally, several biomarkers hold promise in assisting with long-term monitoring. Clinicians should be aware of the multi-system complications that are associated with CP and which may present significant diagnostic challenges given that many children with CP communicate non-verbally. A step-wise, logical, multi-system approach is required to ensure that the best care is provided to these children. This review summarizes multi-organ dysfunction in children with CP whilst highlighting emerging research and gaps in our knowledge. We identify some potential organ-specific biomarkers which may prove useful in developing guidelines for follow-up and management of these children throughout their lifespan.

Abstract
PURPOSE Individuals with cerebral palsy (CP), ambulatory or not, have less bone strength and density than their peers. Aging individuals with CP are at a higher risk for nontraumatic fractures, progressive deformity, pain, and spinal stenosis. Critical periods for skeletal formation are during prepuberty and adolescence. Applying mechanostat theory to exercise design for individuals with CP may be beneficial. METHODS Principles of mechanostat theory, particularly the osteogenic index, is applied to guide the design of exercise programs based on varying levels of physical capacity. RESULTS Recommendations are made for optimizing dosing of a variety of interventions for improving bone health among individuals with CP based on mechanostat theory with specific type, number of repetitions, and frequency. CONCLUSIONS Researchers and clinicians are called to action to consider the role of exercise throughout the lifespan for all individuals with CP, regardless of level of severity.

Abstract
UNLABELLED Bone health problems may be related to the nutritional deficit in pediatric patients with cerebral palsy. It is common to find asymptomatic vertebral fractures when they have low bone mineral density. Fat mass deficit could be related to a lower bone mineral density and a higher risk of vertebral fractures. OBJECTIVES To study the bone health of patients with CP and its relationship with neurological and nutritional status. PURPOSE Cerebral palsy (CP) is the most common cause of motor disability in pediatric age. METHODS Cross-sectional, observational, descriptive, and analytical study in which patients with CP between 4 and 5 years with Gross Motor Function Classification System (GMFCS) grades III-IV-V were included. It was carried out: survey, anthropometric study, bioimpedanciometry (BIA), and bone densitometry. Patients with low bone mineral density (BMD Z score less than - 2.0) underwent lumbar radiography looking for vertebral fractures to be diagnosed with osteoporosis. RESULTS Total sample: 51 patients (51.0% women). Mean age: 11.0 ± 0.5 years. BMD Z score average: - 2.1 (95% CI - 2.5, - 1.7). BMD Z score according to GMFCS: grade III - 1.6 (- 2.2; - 1.), grade IV - 1.6 (- 2.4; - 0.9), grade V - 3.1 (- 3.9, - 2.2) (p = 0.013). Bone health classification according to the International Society for Clinical Densitometry was: 47.1% normal, 52.9% low BMD. Relationship between low BMD and low fat mass (p = 0.030) and low cell mass (p = 0.040) was found. Prevalence of vertebral fractures in lumbar radiography: 25.9%, increasing as the degree of neurological involvement. Vertebral fractures were found in 5/13 GMFCS grade V, 2/6 GMFCS grade IV, and 0/10 GMFCS grade III. CONCLUSIONS Bone health in the pediatric population with CP is compromised in relation to the degree of neurological involvement and nutritional status. Those patients with moderate-severe cerebral palsy and low BMD seem to present an increased risk of fracture.

Abstract
Background Low-magnitude mechanical stimulation (LMMS) may improve skeletal health. The objective of this research was to investigate the long-term residual effects of LMMS on bone health. 10-week old female mice were given LMMS for 8 weeks; SHAM did not receive LMMS. Some groups remained on study for an additional 8 or 16 weeks post treatment (N = 17). Results Epiphyseal trabecular mineralizing surface to bone surface ratio (MS/BS) and bone formation rate (BFR/BS) were significantly greater in the LMMS group compared to the SHAM group at 8 weeks by 92 and 128% respectively. Mineral apposition rate (MAR) was significantly greater in the LMMS group 16 weeks post treatment by 14%. Metaphyseal trabecular bone mineral density (BMD) increased by 18%, bone volume tissue volume ratio (BV/TV) increased by 37%, and trabecular thickness (Tb.Th.) increased by 10% with LMMS at 8 weeks post treatment. Significant effects 16 weeks post treatment were maintained for BV/TV and Tb.Th. The middle-cortical region bone volume (BV) increased by 4% and cortical thickness increased by 3% with 8-week LMMS. Conclusions LMMS improves bone morphological parameters immediately after and in some cases long-term post LMMS. Results from this work will be helpful in developing treatment strategies to increase bone health in younger individuals.

[PMID: 32015744 PMCID: PMC6973987 DOI: 10.1007/s11420-019-09675-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2018] [Accepted: 01/30/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Blade plates are frequently used for internal fixation following proximal femoral varus rotational osteotomy to treat hip dysplasia in children with cerebral palsy. Recently, cannulated blade plates with the option for a proximal locking screw have demonstrated ease of insertion and low complication rates. Although there are two commonly used blade plates with a proximal screw option, no comparison of their biomechanical profiles has been undertaken. QUESTIONS/PURPOSES Our study sought to compare the structural properties under axial loading, as well as the biomechanical contribution of a proximal screw, of two different 90° cannulated blade plates designed for pediatric proximal femurs. Plate A has a hole distal to the blade designed to attach a plate inserter, through which a 3.5-mm non-locking cortical screw could be placed. Plate B has a threaded hole distal to the blade designed to accept a 3.5-mm locking screw. METHODS Plate A and plate B were inserted into 33 left pediatric synthetic proximal femurs. Axial loading to failure of plate A with and without a proximal screw was compared to that of plate B with and without a proximal screw. An additional 10 samples using plate B, with and without a proximal locking screw, were tested in tension to quantify the effect of the proximal screw on pullout strength. RESULTS Plate B failed at a higher axial load than plate A. The addition of a proximal screw did not affect the axial load to failure for either plate. Pullout testing revealed that blade plates fixed with the proximal screw failed in tension at a significantly higher load (856.3 ± 120.9 N) than those without proximal fixation (68.1 ± 9.3 N, p < 0.001). CONCLUSIONS Plate B failed at a higher axial load in biomechanical testing, likely related to differences in its design. The addition of a proximal screw did not increase the axial loading properties of the blade plate construct but did increase the pullout strength by a factor of 12. These results may be used to influence implant selection and post-operative rehabilitation following proximal femoral osteotomies in children.

Abstract
Children with cerebral palsy (CP) are at risk of growth and nutrition disorders. There are numerous challenges to measure and assess growth and nutritional status in children with CP. Addressing these challenges is imperative, because the consequences of poor growth and malnutrition range from decreased bone density, muscle mass, and quality of life to impacts on intellectual quotient, behavior, attention, social participation, healthcare utilization, and health care costs. In addition to discussing approaches to assess growth and nutrition, this article examines some of the methods of optimizing nutrition and bone health, including when preparing for and recovering from surgery.

Abstract
Individuals with cerebral palsy (CP) have an increased risk for the early development of osteoporosis; however, little is known about the epidemiology of osteoporosis for adults with CP, which is vital to inform clinical practice for osteoporosis prevention, treatment, and management. The purpose of this cross-sectional study was to determine sex-stratified prevalence of osteoporosis among adults with CP, as compared with adults without CP. Data from 2016 were extracted from Optum Clinformatics Data Mart (private insurance administrative claims data) and a random 20% sample from the fee-for-service Medicare (public insurance administrative claims data). Diagnostic codes were used to identify CP and osteoporosis diagnoses. Sex-stratified prevalence of osteoporosis was compared between adults with and without CP for the following age groups: 18 to 30, 31 to 40, 41 to 50, 51 to 60, 61 to 70, and >70 years of age. The overall prevalence of osteoporosis was 4.8% for adults without CP (n = 8.7 million), 8.4% for privately insured adults with CP (n = 7,348), and 14.3% for publicly insured adults with CP (n = 21,907). Women and men with CP had a higher prevalence of osteoporosis compared with women and men without CP for all age groups. Finally, publicly insured women and men with CP had a higher prevalence of osteoporosis compared with privately insured women and men with CP for all age groups, except for the similar prevalence among the 18- to 30-year age group. These findings suggest that osteoporosis is more prevalent among adults with CP compared with adults without CP. Study findings highlight the need for earlier screening and preventive medical services for osteoporosis management among adults with CP. © 2019 The Authors.

Abstract
Individuals with cerebral palsy exhibit neuromuscular complications and low physical activity levels. Adults with cerebral palsy exhibit a high prevalence of chronic diseases, which is associated with musculoskeletal deficits. Children with cerebral palsy have poor musculoskeletal accretion accompanied by excess bone marrow fat, which may lead to weaker bones. Mechanistic studies to determine the role of bone marrow fat on skeletal growth and maintenance and how it relates to systemic energy metabolism among individuals with cerebral palsy are lacking. In this review, we highlight the skeletal status in children with cerebral palsy and analyze the existing literature on the interactions among bone marrow fat, skeletal health, and cardiometabolic disease risk in the general population. Clinically vital questions are proposed, including the following: (1) Is the bone marrow fat in children with cerebral palsy metabolically distinct from typically developing children in terms of its lipid and inflammatory composition? (2) Does the bone marrow fat suppress skeletal acquisition? (3) Or, does it accelerate chronic disease development in children with cerebral palsy? (4) If so, what are the mechanisms? In conclusion, although inadequate mechanical loading may initiate poor skeletal development, subsequent expansion of bone marrow fat may further impede skeletal acquisition and increase cardiometabolic disease risk in those with cerebral palsy.

Abstract
Adaptive sports athletes represent a growing population within the athletic community worldwide. Given potential cardiometabolic and psychosocial benefits of adaptive sports participation, the impact on bone health and injury risk in adaptive athletes is of increasing clinical interest. Impaired bone health as a result of low energy availability has been well described in able-bodied athletic women and, more recently, men as part of the female athlete triad and Relative Energy Deficiency in Sport (RED-S). However, the applicability of these models to adaptive athletes remains unclear given altered physiology and biomechanics compared with able-bodied counterparts. Thus, a literature review was completed to characterize the influence of adaptive sports participation and associated risk factors for impaired bone health in this unique population. To date, limited investigations demonstrate a consistent, positive effect of sports participation on bone health. Risk factors for impaired bone health include low energy availability and micronutrient deficiency.

Abstract
STUDY DESIGN A retrospective review. OBJECTIVE The aim of this study was to assess correction of pelvic obliquity in children with cerebral palsy (CP) scoliosis postoperatively and 5 years after posterior spinal fusion with pelvic fixation using unit rods, sacral-alar-iliac (SAI) screws, or iliac screws. SUMMARY OF BACKGROUND DATA There are multiple options for pelvic fixation in children with scoliosis secondary to CP. The long-term differences in outcomes between these fixation methods are still unclear. METHODS A multicenter review identified records of 70 children with CP who underwent posterior spinal fusion for scoliosis using unit rods (n = 9), SAI screws (n = 19), or iliac screws (n = 42). Patients younger than 18 years with 5-year follow-up were included. Pelvic obliquity and major coronal curve measurements were compared using preoperative, (first erect) postoperative, and 5-year follow-up radiographs. Implant-related complications were noted. Alpha = 0.05. RESULTS For all groups, there was a significant difference between preoperative and postoperative pelvic obliquity that was maintained at 5 years. At 5-year follow-up, pelvic obliquity was significantly higher in the IS group (12°) compared with the unit rod group (4°, P = 0.001) and SAI screw group (6°) (P = 0.006). Implant-related complications were as follows: unit rod group, one patient (reoperation); SAI screw group, none; iliac screw group, six patients, including three cases of loss of connection between the rod and the iliac screw, two prominent screws, and one loose screw. CONCLUSION Correction of pelvic obliquity for children with CP-related scoliosis was achieved postoperatively using unit rods, SAI screws, and iliac screws. Implant-related complications and reoperations were most common in the iliac screw group. At 5-year follow-up, the iliac screw group had loss of major curve correction and less correction of pelvic obliquity than the unit rod and SAI screw groups. LEVEL OF EVIDENCE 3.

Abstract
CONTEXT Bone fragility in cerebral palsy (CP) is secondary to a complex interplay of functional, hormonal, and nutritional factors that affect bone remodelling. A greater understanding of bone microarchitectural changes seen in CP should assist therapeutic decision making. OBJECTIVE To examine the relationship between trabecular bone score (TBS), BMD and fractures in adults with CP; the influence of clinical factors and body composition on bone microarchitecture were explored. DESIGN Retrospective cross-sectional study. SETTING AND PARTICIPANTS 43 adults (25 male) with CP of median age 25 years (interquartile range 21.4-33.9) who had evaluable dual-energy X-ray absorptiometry imaging of the lumbar spine from a single tertiary hospital between 2005-March 2018. RESULTS 24/43 (55.8%) of patients had TBS values indicating intermediate or high risk of fracture (<1.31). TBS correlated with areal BMD at the lumbar spine, femoral neck and total body. TBS was significantly associated with arm and leg lean mass, with adjustment for age, gender and height (adjusted R2 = 0.18, p = 0.042 for arm lean mass; adjusted R2 = 0.19, p = 0.036 for leg lean mass). There was no difference in TBS when patients were grouped by fracture status, anticonvulsant use, gonadal status or use of PEG feeding. TBS was lower in non-ambulatory patients compared with ambulatory patients (1.28 vs 1.37, p = 0.019). CONCLUSIONS Abnormal bone microarchitecture, as measured by TBS, was seen in >50% of young adults with CP. TBS correlated with both areal BMD and appendicular lean mass. Maintaining muscle function is likely to be important for bone health in young adults with CP and needs to be confirmed in further studies.

Abstract
Low energy availability, functional hypothalamic amenorrhea, and low bone mineral density are three interrelated conditions described in athletic women. Although described as the female athlete triad (Triad), males experience similar health concerns. The literature suggests that individuals with a disability may experience altered physiology related to these three conditions when compared with the able-bodied population. The goal of this review is to describe the unique implications of low energy availability, low bone mineral density, and, in females, menstrual dysfunction in individuals with a disability and their potential impact on the para athlete population. A literature review was performed linking search terms related to the three conditions with six disability categories that are most represented in para sport. Few articles were found that directly pertained to athletes, therefore, the review additionally characterizes literature found in a non-athlete population. Review of the available literature in athletes suggests that both male and female athletes with spinal cord injury demonstrate risk factors for low energy availability. Bone mineral density may also show improvements for wheelchair athletes or athletes with hemiplegic cerebral palsy when compared with a disabled non-athlete population. However, the prevalence of the three conditions and implications on the health of para athletes is largely unknown and represents a key gap in the sports medicine literature. As participation in para sport continues to increase, further research is needed to understand the impact of these three interrelated health concerns for athletes with a disability, accompanied by educational initiatives targeting athletes, coaches, and health professionals.

Abstract
Purpose: Non-ambulatory persons with cerebral palsy are prone to low bone mineral density. In ambulatory persons with cerebral palsy, bone mineral density deficits are expected to be small or absent, but a consensus conclusion is lacking. In this systematic review bone mineral density in ambulatory persons with cerebral palsy (Gross Motor Function Classification Scales I-III) was studied. Materials and methods: Medline, Embase, and Web of Science were searched. According to international guidelines, low bone mineral density was defined as Z-score ≤ -2.0. In addition, we focused on Z-score ≤ -1.0 because this may indicate a tendency towards low bone mineral density. Results: We included 16 studies, comprising 465 patients aged 1-65 years. Moderate and conflicting evidence for low bone mineral density (Z-score ≤ -2.0) was found for several body parts (total proximal femur, total body, distal femur, lumbar spine) in children with Gross Motor Function Classification Scales II and III. We found no evidence for low bone mineral density in children with Gross Motor Function Classification Scale I or adults, although there was a tendency towards low bone mineral density (Z-score ≤ -1.0) for several body parts. Conclusions: Although more high-quality research is needed, results indicate that deficits in bone mineral density are not restricted to non-ambulatory people with cerebral palsy. Implications for Rehabilitation Although more high-quality research is needed, including adults and fracture risk assessment, the current study indicates that deficits in bone mineral density are not restricted to non-ambulatory people with CP. Health care professionals should be aware that optimal nutrition, supplements on indication, and an active lifestyle, preferably with weight-bearing activities, are important in ambulatory people with CP, also from a bone quality point-of-view. If indicated, medication and fall prevention training should be prescribed.

Abstract
BACKGROUND The US Centers for Disease Control and Prevention estimate that 3.5 million children use psychotropic drugs for attention-deficit hyperactivity disorder (ADHD). With an increase in use of these types of drugs, thorough understanding of their potential side effects on the growing skeleton is needed. The purpose of this study was to determine whether there is an association between use of ADHD medication and diminished bone health. METHODS Three waves of the National Health and Nutrition Examination Survey public-use data set, collected from 2005 through 2010, were compiled for this study (N=5315). Bone health was measured using dual-energy x-ray absorptiometry scans, which were performed for participants aged 8 to 17 years to determine bone mineral density (BMD) for 3 regions: (1) total femur; (2) femoral neck; and (3) lumbar. Use of ADHD medications was determined by self-reported responses to questions regarding prescription drug use, which were answered by either the respondent or the respondent's parent or guardian. Multiple statistical techniques were used to produce estimates of association between ADHD medication use and z score age and sex standardized BMD measures, including survey adjusted univariate, survey adjusted multiple linear regression, and generalized estimating equations with a propensity-matched subsample (N=1967). Multivariate models adjusted for covariates including time period, age, sex, race/ethnicity, family income to poverty ratio, and total number of prescription medications. RESULTS Conservative estimates of the difference in standardized BMD measures between the ADHD medication group and the nonmedicated group range from -0.4855 (±0.27; P<0.001) for total femoral, -0.4671 (±0.27; P<0.001) for femoral neck, and -0.3947 (±0.29; P<0.01) for lumbar. Significantly more children on ADHD medications versus match subjects on no medication had BMDs with in osteopenic range (38.3% vs. 21.6%, P<0.01). DISCUSSION The findings suggest that there are real and nontrivial differences in BMD for children and adolescents taking ADHD medications, as compared with similar children not taking any prescription medications. Prescribing physicians and parents should be aware of potential bone health risks associated with these medications. LEVEL OF EVIDENCE Level III-case-control study.

Abstract
BACKGROUND The present study aims to explore the effect of weight bearing exercise on bone mineral density (BMD) and bone growth in children with cerebral palsy (CP). METHODS Twelve children with CP of functional level of gross motor functional classification scale (GMFCS) V and 6 healthy children (control group) were included in the study. Participants underwent a dual-energy X-ray absorptiometry scan to measure the BMD of the femur and full-length anteroposterior radiography to measure the bone length of the femur and tibia at baseline and after 6 months. Patients were randomly divided into 2 groups: group A with programmed standing exercises and assisted standing for more than 2 hours a day, more than 5 days a week; and group B with conventional physiotherapy with a standing program for 20 minutes a day, 2 to 3 days a week. RESULTS A 6-month follow-up showed significantly increased BMD on the femur neck in the control group. Although the changes in BMD were not significant in both groups, group A demonstrated an increased trend of BMD, whereas group B showed a decreased trend. Bone length was significantly increased in all 3 groups at the 6-month follow-up. Although this increase was not significant, the change in bone length was greatest in the control group. The smallest changes were observed in group B. CONCLUSIONS Weight bearing exercise may play an important role in increasing or maintaining BMD in children with CP and is also expected to promote bone growth. Programmed standing may be used as an effective treatment method to increase BMD in children with CP. However, further studies with a larger cohort and longer follow-up period are required to reveal further information on the benefit of weight bearing exercise and to develop a detailed program.

Abstract
PURPOSE This retrospective study evaluated mid-to-long-term outcome of a minimally invasive percutaneous pelvic osteotomy (PPO) approach combined with varus derotational shortening osteotomy (VDRSO) and soft tissue release in children with severe CP. METHODS A retrospective review was performed of all patients presenting with a diagnosis of CP with hip subluxation or dislocation treated surgically by simultaneous soft tissue release, VDRSO, and PPO between 2002 and 2015. Eligible patients included those with a diagnosis of spastic quadriplegia or CP GMFCS level IV or V with unilateral or bilateral hip subluxation or dislocation and surgical treatment of the deformity by simultaneous soft tissue release, VDRSO and PPO. All anterior-posterior (AP) radiographs of the pelvis were reviewed and Reimers migration percentage (MP) and acetabular angle (AA) were measured. RESULTS In total, 54 children and adolescents (34 boys, 20 girls) with CP GMFCS level IV and V were treated during study period: 38 (70.4%) classified GMFCS level IV and 16 (29.6%) classified GMFCS level V. A total of 64 consecutive hips underwent simultaneous PPO associated with VDRSO. Overall, at the time of chart and radiograph review, mean age was 9.1 ± 3.3 years (range 4-16.5) and mean follow-up was 43.9 ± 19.5 months (range 3-72). Mean migration percentage improved from 66.8 ± 19.8% (range 33-100) preoperatively to 8.1 ± 16.5% (range 0-70) at last follow-up. Mean acetabular angle improved from 32.7° ± 7.1° (range 20-50) preoperatively to 14° ± 6.7° (range 0-27) at last follow-up. Only one case of bone graft dislodgment was observed. We did not observe any cases of avascular necrosis of the femoral head. All operated hips were pain free at the time of last follow-up. CONCLUSION PPO through a less invasive surgical approach offers a valuable alternative to standard techniques as it gives similar outcome but with less muscle stripping and less time in surgery.

Abstract
PURPOSE We aimed to evaluate the relationship between bone mineral density (BMD) disorders and possible risk factors in patients with epilepsy only (EO), cerebral palsy only (CPO), and cerebral palsy-epilepsy (CP + E). METHODS A total of 122 patients [EO (n = 54), CPO (n = 30), CP + E (n = 38)] and 30 healthy children were evaluated. BMD was only measured in patient groups, not in control subjects. BMD of lumbar vertebrae was determined by dual energy X-ray absorptiometry (DXA). An abnormal BMD was defined as low or low normal BMD. RESULTS Low BMD rate in EO, CPO, and CP + E group was 3.7, 50, and 39.5 %, respectively. Abnormal BMD values were significantly related to inadequate dietary Ca intake (p = 0.017), severe intellectual disability (p < 0.001), and immobility (p = 0.018). In multivariate regression analysis, the risk of abnormal BMD was higher (3.9-fold) in patients not able to walk independently than the others (p = 0.029). However, serum Ca-Vitamin D levels, insufficient exposure to sunlight, low BMI, and use of AED were not correlated with abnormal BMD. CONCLUSION Abnormal BMD is a common problem in patients with CP and CP + E. Abnormal BMD was related to the severity of CP, but not to vitamin D levels or AED treatment.

Abstract
AIM We aimed to evaluate the bone mineral density of the hip joint in patients with cerebral palsy (CP). METHOD Patients with CP younger than 18 years who underwent three-dimensional hip examination by computed tomography were analysed. Bone attenuation of the acetabulum and femur was measured as Hounsfield units (HU), and was adjusted for affecting factors such as hip instability and Gross Motor Function Classification System (GMFCS). RESULTS One hundred and twenty-six patients with CP and 86 typically developing participants were included. The average bone attenuation was significantly lower in those with CP than in the comparison group (acetabulum: 70.8HU, 95% confidence interval [95% CI] 59.9-81.8; femur: 82.2HU, 95% CI 70.4-95.8). Compared with GMFCS levels I to III, bone attenuation was significantly lower for GMFCS levels IV (acetabulum: 30.9HU, 95% CI 15.7-46.2; femur: 39.7HU, 95% CI 19.9-59.5) and V (acetabulum: 51.7HU, 95% CI 35.9-67.5; femur: 72.5HU, 95% CI 51.9-93.0). The average bone attenuation decreased when the migration percentage was over 37% (acetabulum: 11.6HU, 95% CI 1.4-24.6; femur: 26.8HU, 95% CI 9.9-43.6). INTERPRETATION Bone attenuation of the acetabulum and femur was significantly affected both by GMFCS level and by severity of hip instability.

Abstract
INTRODUCTION Diminished bone mineral density and delayed skeletal maturation are common in children with spastic quadriplegia. AIM The purpose of our study was to evaluate the Bone Mineral Density (BMD) of children with moderate to severe spastic quadriplegia and its relationship with other variables like nutrition and growth. MATERIALS AND METHODS This was a hospital based, cross- sectional, case-control study. Forty-two (28 males, 14 females) children with spastic quadriplegia and 42 (24 males, 18 females) healthy children were included in the study. BMD of cases and control were measured by Dual Energy X-ray Absorptiometry (DEXA). Radiographs of left hand and wrist of cases and controls were taken and bone age was determined. RESULTS BMD values of upper extremity, lower extremity, thoraco-lumbar spine and pelvis in cases were lower than those of controls (p <0.0001). In children with non severe malnutrition, 75% of the cases had lower bone age than chronological age, whereas all cases with severe malnutrition had lower bone age than chronological age. Step wise regression analysis showed that nutritional status independently contributed to lower BMD values but the BMD values did not correlate significantly with the use of anticonvulsant drugs and presence of physical therapy. CONCLUSION Decreased BMD and delayed bone age is prevalent in children with spastic quadriplegia and nutritional status is an important contributing factor.

Disrupted Bone Metabolism in Long-Term Bedridden Patients. PLoS One 2016; 11:e0156991.

Abstract
BACKGROUND Bedridden patients are at risk of osteoporosis and fractures, although the long-term bone metabolic processes in these patients are poorly understood. Therefore, we aimed to determine how long-term bed confinement affects bone metabolism. METHODS This study included 36 patients who had been bedridden from birth due to severe immobility. Bone mineral density and bone metabolism markers were compared to the bedridden period in all study patients. Changes in the bone metabolism markers during a follow-up of 12 years were studied in 17 patients aged <30 years at baseline. RESULTS The bone mineral density was reduced (0.58±0.19 g/cm3), and the osteocalcin (13.9±12.4 ng/mL) and urine N-terminal telopeptide (NTX) levels (146.9±134.0 mM BCE/mM creatinine) were greater than the cutoff value for predicting fracture. Among the bone metabolism markers studied, osteocalcin and NTX were negatively associated with the bedridden period. During the follow-up, osteocalcin and parathyroid hormone were decreased, and the 25(OH) vitamin D was increased. NTX at baseline was negatively associated with bone mineral density after 12 years. CONCLUSIONS Unique bone metabolic abnormalities were found in patients who had been bedridden for long periods, and these metabolic abnormalities were altered by further bed confinement. Appropriate treatment based on the unique bone metabolic changes may be important in long-term bedridden patients.

Abstract
BACKGROUND Some children with cerebral palsy (CP) have frequent fractures due to low bone mineral density and receive treatment with pamidronate, an intravenous bisphosphonate. Our review evaluates the outcome of pamidronate treatment in these children. METHODS A retrospective chart review was performed, and 32 patients (14 girls and 18 boys) with CP Gross Motor Function Classification System level III (2 patients), IV (3 patients), and V (27 patients) treated with 5 courses of pamidronate for low mineral density were identified. Patients with a minimum of 2 years of follow-up were included in the study. Data collection was a review of the demographics and pretreatment, peritreatment, and posttreatment fracture history. RESULTS The mean age at treatment was 11.6 years (range, 2.9 to 19.6 y). There were 102 fractures (mean duration 2.5 y) pretreatment and 28 fractures posttreatment. With an average follow-up of 6.4 years, posttreatment rate of fracture decreased to 0.10 fractures per year from the pretreatment rate of 2.4 fractures per year (P<0.001). The femur was the most common bone fractured both pretreatment (54%) and posttreatment (61%); the major site was the distal third of the femur. There were 11 fractures during the course of pamidronate treatment at a rate of 0.33 fractures per year. Only 11 patients (34%) sustained fracture posttreatment. No correlation with fracture pattern or occurrence was found with patient age, number of pretreatment fractures, or sex. Most fractures were caused by low-energy injuries, and most were managed nonoperatively. CONCLUSIONS In patients with CP and disuse osteoporosis, the most common fracture sustained involved the distal femur via low-velocity injury, and most fractures were treated nonoperatively. Although the fracture pattern and the treatment remained unchanged, reoccurring fractures in these children can be effectively treated medically to interrupt the fracturing tendency.

Abstract
Children with underlying metabolic bone diseases, such as osteogenesis imperfecta and spastic cerebral palsy, pose a challenge in the treatment of femoral shaft fractures. We performed flexible intramedullary nailing with supplemental monolateral external fixation in a subgroup of such patients. The external fixator assists in controlling angulation and rotation at the fracture site, and avoids the need for supplemental casting with its associated problems such as skin breakdown and difficulty with personal hygiene. We describe the surgical technique, pitfalls, and outcomes in a series of four patients with underlying osteopenia treated with external fixator-augmented flexible nailing for femoral shaft fractures.

Abstract
STUDY DESIGN Biomechanical cadaveric study. OBJECTIVE To compare the biomechanical properties of the iliac and S2-Alar-Iliac (S2AI) screw in a similar spinopelvic fixation construct. SUMMARY OF BACKGROUND DATA Spinopelvic fixation is used in the correction of pelvic obliquity, high-grade spondylolisthesis, and long spinal fusions. With the development of pedicle screw fixation, the iliac screw has been used as an anchor point to the pelvis. The associated morbidity with this fixation has led to the development of the S2AI screw. Many studies have examined the biomechanical properties of iliac and S2AI screws; however, a direct comparison has not been performed. METHODS Eight cadaveric spines were instrumented with pedicle screws bilaterally at L5 and S1. Four specimens were further instrumented with iliac screws placed with a starting point at the posterior superior iliac spine, and four specimens were instrumented with S2AI screws placed with a starting point 1 mm inferolateral to the S1 foramen. Screws were connected with 6.35 mm rods. Subfailure testing was performed by loading at 1°/second to a torque of 10 Nm in four directions: left bending, right bending, extension, and flexion. Specimens then underwent a monotonic load to failure under flexion at a rate of 1°/second. RESULTS There were no significant differences for torsional stiffness in extension, flexion, left bending, or right bending between S2AI and iliac screw constructs. There were no significant differences in S2AI versus iliac screws for failure torque (30.9 ± 12.00 Nm vs. 22.61 ± 6.25 Nm) and yield torque (11.86 ± 0.41 Nm vs. 12.01 ± 1.70 Nm). CONCLUSION Iliac screws have been associated with increased dissection, wound complications, an additional construct failure point, and hardware prominence. The S2AI screw was developed as an alternative and has been associated with less morbidity. The iliac and S2AI screw demonstrate no statistical difference in stiffness and load-to-failure in a spinopelvic fixation model. LEVEL OF EVIDENCE Level V.

Abstract
AIM Osteoporosis is a significant clinical problem in persons with moderate to severe cerebral palsy (CP), causing fractures with minimal trauma. Over the past decade, most studies examining osteoporosis and CP have been cross-sectional in nature, focused exclusively on children and adolescents and only involving one evaluation of bone mineral density (BMD). The purpose of this study was to assess BMD in a group including adults with CP, and changes in each individual's BMD over a 5- to 6-year period. METHOD The study group included 40 residents of a long-term care facility aged 6 to 26 years at the time of their initial evaluation. Twenty-one patients (52.5%) were male, 35 (88%) were white, and 38 (95%) were in Gross Motor Function Classification System level V. BMD was assessed by dual-energy X-ray absorptiometry on the right and left distal femurs for three distinct regions of interest. RESULTS Five residents had a fracture that occurred during the study period; this represented a fracture rate of 2.1% per year in the study group. Longitudinally, annualized change in the median BMD was 0.7% to 1.0% per year in the different regions of the distal femur, but ranged widely among the study group, with both increases and decreases in BMD. Increase in BMD over time was negatively correlated with age and positively correlated with change in weight. INTERPRETATION Changes in BMD over time in profoundly involved persons with CP can range widely, which is important to recognize when evaluating potential interventions to improve BMD. Age and changes in body weight appear the most relevant factors.

Abstract
Objective To evaluate bone mineral density among patients with neuromuscular scoliosis secondary to quadriplegic cerebral palsy. Methods This was a descriptive prospective study in which both bone densitometric and anthropometric data were evaluated. The inclusion criteria used were that the patients should present quadriplegic cerebral palsy, be confined to a wheelchair, be between 10 and 20 years of age and present neuromuscular scoliosis. Results We evaluated 31 patients (20 females) with a mean age of 14.2 years. Their mean biceps circumference, calf circumference and body mass index were 19.4 cm, 18.6 cm and 16.9 kg/m2, respectively. The mean standard deviation from bone densitometry was −3.2 (z-score), which characterizes osteoporosis. Conclusion There is high incidence of osteoporosis in patients with neuromuscular scoliosis secondary to quadriplegic cerebral palsy.

Abstract
BACKGROUND Segmental spinal instrumentation with Luque wire fixation has been the standard treatment of neuromuscular scoliosis for >30 years. More recently, pedicle screw constructs have become the most widely utilized method of posterior spinal fixation; however, they are associated with complications such as implant malposition. We report the use of polyester bands and clamps utilized with pedicle screws in a hybrid fixation construct in the treatment of neuromuscular scoliosis. METHODS A retrospective review was conducted of 115 pediatric spinal deformity cases between 2008 and 2010 at a single center performed by a single surgeon. Intraoperative and postoperative complications were recorded. Radiographs were reviewed preoperatively and at the latest follow-up. A systematic review of the literature was conducted. Data from case series reporting outcomes of sublaminar wires and all-pedicle screw constructs in the treatment of neuromuscular scoliosis were compared with outcomes of the present study. RESULTS Twenty-nine patients with neuromuscular scoliosis who underwent segmental spinal instrumentation with a hybrid construct including sublaminar bands and pedicle screws were included. There was an average follow-up of 29 months (range, 12 to 40 mo). The average postoperative correction of coronal balance was 69% (range, 24 to 71 degrees). Sagittal balance was corrected to within 2 cm of the C7 plumbline in 97% of patients. The loss of coronal and sagittal correction at latest follow-up was 0% and 2%, respectively. There were 2 intraoperative clamp failures of the 398 implants (0.5%). There were 2 major (6.9%) and 7 minor (24%) complications in 7 patients (24% overall). These results compared favorably to previous case series of sublaminar wire and all-pedicle screw fixation techniques. CONCLUSIONS The polyester band technique is an excellent adjunct in the correction of spinal deformity in patients with neuromuscular scoliosis. Sublaminar bands utilized in a hybrid construct appear to be safe, can achieve corrections equivalent to all-pedicle screw constructs, and may decrease the potential complications associated with every level transpedicular fixation in the patient with a highly dysmorphic and osteoporotic spine.

Abstract
Adults with cerebral palsy (CP) are known to have low bone mass with an increased risk of fragility fracture. CP is classified into two major types: spastic (pyramidal) and dyskinetic (extrapyramidal). Spastic CP is the most common and is characterized by muscle hypertonicity and impaired neuromuscular control. By contrast, dyskinetic CP is characterized by mixed muscle tone with involuntary movements. The aim of this study was to elucidate the relationship between bone metabolism and subtype of CP. Fifty-eight adults with CP (aged 18 to 49years, mean age 33.2years; 32 men, 26 women) were included in this cross-sectional analysis. Lumbar spine and femoral bone mineral density (BMD) Z-scores were measured. Bone markers, including C-telopeptide of type I collagen (CTx) and osteocalcin (OCN), were also analyzed. Among these participants, 30 had spastic CP and 28 had dyskinetic CP. The Z-scores of lumbar spine BMD did not differ between the two types. However, the Z-scores of femur trochanteric BMD were significantly lower in participants with spastic CP than in those with dyskinetic CP (-1.6±1.2 vs. -0.9±1.1, p<0.05). Seventy-four percent of participants with either type of CP had abnormally elevated CTx, while about 90% of participants showed normal OCN levels. When participants were subclassified into nonambulatory and ambulatory groups, the nonambulatory group had significantly lower BMD in the femur, including the trochanteric and total regions, whether they were spastic or dyskinetic (p<0.05). Because the type of CP affects bone mass, nonambulatory spastic CP participants showed the lowest total hip region BMD among the four groups. These results reveal that reduced weight bearing and immobility related to CP cause a negative bone balance because of increased bone resorption, which leads to a lower bone mass. In addition, hypertonicity of the affected limbs in participants with spastic CP resulted in lower bone mass than in those with dyskinetic CP. Type of CP and degree of ambulatory function in adults with CP should be regarded as important factors affecting bone metabolism.

UNLABELLED This study assessed distal femur and lumbar spine bone mineral density (BMD) Z-scores in children with cerebral palsy. BMD z-score was lower in non-ambulatory than in ambulatory children. Somewhat surprisingly, among ambulatory children, those with better walking abilities had higher BMD z-score than those with more impaired walking ability. INTRODUCTION Children with cerebral palsy (CP) have increased risk for low bone mineral density (BMD). The aim was to explore the difference in BMD at the distal femur and lumbar spine between ambulatory and non-ambulatory children with CP and the relationship between vitamin D status and BMD. METHODS Fifty-one children (age range 8-18 years; 20 girls) with CP participated. Their BMD Z-scores were measured in the lumbar spine and the distal femur using dual X-ray absorptiometry, and 25-hydroxy-vitamin D (25-OHD) concentrations were measured in serum. Children with GMFCS level I-III were defined as 'walkers' while children with level IV-V were defined as 'non-walkers. RESULTS Non-walkers had lower mean BMD Z-scores (range -1.7 to -5.4) than walkers at all sites (range -0.8 to -1.5). Among walkers, BMD Z-scores at the distal femur were lower in those with GMFCS level II than with level I (p values < 0.004). A similar difference was found between the affected and unaffected limb in children with hemiplegia. Mean 25-OHD concentration was 45 nmol/L (SD = 18); lower in walkers (mean = 41 nmol/L; SD = 18) than in non-walkers (mean = 53 nmol/L; SD = 19; p = 0.041). There were no correlations between 25-OHD and BMD z-scores. CONCLUSIONS The main predictor of low BMD Z-scores in the distal femur was the inability to walk, but the results suggest that the degree of the neuromotor impairment may also be a significant predictor. Vitamin D status did not correlate with BMD z-scores.

Abstract
AIMS Innovative robotic technologies hold strong promise for improving walking abilities of children with cerebral palsy (CP), but may create expectations for parents pursuing the "newest thing" in treatment. The aim of this qualitative study was to explore parents' values about walking in relation to their experiences with robotic gait training for their children. METHODS Semi-structured interviews were conducted with parents of five ambulatory children with CP participating in a randomized trial investigating robotic gait training effectiveness. RESULTS Parents valued walking, especially "correct" walking, as a key component of their children's present and future well-being. They continually sought the "next best thing" in therapy and viewed the robotic gait trainer as a potentially revolutionary technology despite mixed experiences. CONCLUSIONS The results can help inform rehabilitation therapists' knowledge of parents' values and perspectives, and guide effective collaborations toward meeting the therapeutic needs of children with CP.

Abstract
OBJECTIVE: To evaluate bone mineral density in patients with neuromuscular scoliosis secondary to spastic quadriplegic cerebral palsy. METHODS: A prospective descriptive study in which, in addition to bone densitometry, the anthropometric data of the patients were assessed. As inclusion criterion we adopted patients with spastic quadriplegic cerebral palsy, wheelchair users, aged between 10 and 20 years and with neuromuscular scoliosis. RESULTS: We evaluated 31 patients, 20 female, whose average age was 14.2 years. The mean bone density was -3.2 standard deviation (Z-score), with mean biceps circumference of 19.4 cm, calf circumference 18.6 cm and BMI of 13.6 kg/m². CONCLUSION: There is a high incidence of osteoporosis in patients with neuromuscular scoliosis secondary to spastic quadriplegic cerebral palsy.

Abstract
BACKGROUND Patients with Rett syndrome (RTT) are at risk of having low bone mass and low-energy fractures. METHODS We characterized bone metabolism by both bone formation and resorption markers in blood in a RTT population of 61 girls and women and 122 well-matched healthy controls. Levels of N-terminal propeptides of collagen type 1 (P1NP), C-terminal telopeptide cross links (CTX), osteocalcin (OC), and bone-specific alkaline phosphatase (B-ALP) were compared between RTT patients and controls in regression models adjusted for BMI, vitamin D status, volumetric bone mineral apparent density of the lumbar spine (vBMAD spine), and femoral neck (vBMAD neck). We examined biochemical bone marker levels overall and stratified to persons younger than age 25 y or equal to or older than age 25 y. RESULTS The RTT patients had reduced levels of all biochemical bone markers (P < 0.05), which remained significant in persons younger than 25 y (P ≤ 0.001) regarding P1NP, CTX, and OC. Bone marker levels were not significantly associated to methyl-CpG-binding protein 2 (MECP2) mutation group, walking ability, or previous low-energy fractures. CONCLUSION Our findings of a low bone turnover state in girls with RTT suggest critical attention to medical treatment of low bone mass in young RTT patients.

Abstract
UNLABELLED The 12-week home-based virtual cycling training (hVCT) improved lower limb muscle strength and areal bone mineral density (aBMD) than the control program in children with cerebral palsy (CP). A muscle strengthening program, rather than general physical activity, is more specific in enhancing aBMD for these children. A novel hVCT is an effective and efficient strategy that enhances lower limb bone density in these children. INTRODUCTION This is the first study to assess the efficacy of a novel hVCT program on bone density for children with spastic CP using a well-designed randomized controlled trial. METHODS Twenty-seven ambulatory children with spastic CP, aged 6-12 years, were randomly assigned to the hVCT group (n=13) or control group (n=14). Outcome measures-motor function [Gross Motor Function Measure-66 (GMFM-66)], muscle strength (curl up scores and isokinetic torque of knee extensor and flexor muscle) and aBMD of the lumbar and distal femur-were administered before and immediately after the 12-week intervention. RESULTS Analysis of covariance results show that the hVCT group had greater distal femur aBMD and isokinetic torques of knee extensor and flexor muscles than the control group at posttreatment (p<0.05). However, curl up scores, GMFM-66, and lumbar aBMD at posttreatment did not differ between the two groups. CONCLUSIONS Analytical findings suggest that the muscle strengthening program is more specific in enhancing bone density for children with CP than general physical activity. Thus, the proposed 12-week hVCT protocol is an effective and efficient strategy for improving lower limb aBMD in these children.

Abstract
This study evaluated the outcome of severe cerebral palsy patients (Gross Motor Function Classification System level IV and V) treated by simultaneous percutaneous pelvic osteotomy and intertrochanteric varus shortening osteotomy for hip subluxation or dislocation between 2002 and 2011. Twenty-four patients (30 hips) with an average age of 9.4 years (5-16.5) were reviewed at a mean follow-up of 35.9 months (6-96). Percutaneous pelvic osteotomy lasted on average 30 min/patient per side (25-40) and was always performed through a skin incision of 2-3 cm. The migration percentage and acetabular angle were assessed on plain radiographs. The mean Reimers' migration percentage improved from 67.1% (42-100) preoperatively to 7.7% (0-70) at the last follow-up and the mean acetabular angle improved from 31.8° (22-48) to 15.7° (5-27). Five patients presented complications: one redislocation, one bone graft dislodgement, and three with avascular necrosis of the femoral head. This study should be considered as a pilot study. These results indicate that this combined approach is an effective, reliable, and minimally invasive alternative method for the treatment of spastic dislocated hips in severe cerebral palsy patients with an outcome similar to standard techniques reported in the literature.

Abstract
UNLABELLED Pain in children with cognitive impairment and cerebral palsy is a particularly relevant issue due to its high prevalence and impact on quality of life. We review available evidence about prevalence of pain, causes and specific treatment, recognition and use of specific pain scales, physiology, and consequences of pain in this subset of patients. CONCLUSIONS Pain is very common and is a critical determinant of quality of life in children with cognitive impairment and cerebral palsy. The diseases and associated complications that frequently expose these patients to pain can be treated and pain prevented. For patients with communication difficulties, appropriate, effective, validated tools are available and should be used to diagnose pain in itself, to >choose analgesic treatment and to determine effectiveness of these therapies. The level of awareness of pediatricians towards this issue seems to be quite low.

Abstract
BACKGROUND To our knowledge, there are no comprehensive clinical studies of implant-related fractures in children. Our goal was to identify the incidence, skeletal location, and associated diagnoses of implant-related fractures. METHODS We reviewed our institutional database to identify cases of implant insertion (7584 cases) in patients less than 18 years old from January 1, 1995 through December 31, 2009. We calculated the overall incidence of these fractures and stratified the incidence by skeletal location and preoperative diagnoses. Fisher exact test was used to ascertain differences in fracture incidence. Risk ratios were calculated when appropriate. Significance was set at P<0.05. RESULTS There were 25 cases of implant-related fractures: 22 in the femur, 2 in the tibia, and 1 in the radius. The overall incidence of implant-related fracture was 0.33%; the incidence by skeletal location was: femur, 0.89%; tibia, 0.1%; and radius, 0.14%. Associated diagnoses were cerebral palsy (9 cases), hip dysplasia (3 cases), spina bifida (2 cases), and avascular necrosis (1 case); 10 cases were associated with "other diagnoses," which included various skeletal syndromes (5 cases) and traumatic fractures (5 cases). The incidences of implant-related fractures by diagnoses were: cerebral palsy, 1.1%; hip dysplasia, 1.1%; spina bifida, 1.3%; and avascular necrosis, 0.35%. The incidence of implant-related fracture in the "other diagnoses" group was 0.16%, and the incidence of fracture in otherwise healthy patients was 0.084%. The femur was 15.2 times more likely to fracture than other bones (P<0.001). Diagnoses of cerebral palsy, hip dysplasia, spina bifida, and avascular necrosis were 6.1 times more likely to be associated with implant-related fractures than the "other diagnoses" (P<0.001). The mean time to fracture in the study was 2.8 years. The overall implant removal rate at our institution was 24.3%, and it varied significantly by patient diagnosis (P<0.01). CONCLUSIONS Skeletal location and preoperative diagnosis should be factors of consideration in a surgeon's decision about removing implants to prevent implant-related fractures. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
OBJECTIVE To determine the bone mineral density (BMD) values in children and adolescents with moderate and severe infantile cerebral palsy (ICP) in our catchment area, and compare these values with a healthy population. MATERIAL AND METHOD A prognostic study of cases and controls for the assessment of BMD in patients from 2 to 18 years old with infantile cerebral palsy belonging to the Gross Motor Function Classification System (GMFCS) Groups IV and V. The BMD measurements were performed at distal femur level, dividing this region into 3 areas following the forearm protocol. RESULTS The BMD for each of the three areas studied results in the final sample of 69 patients were much lower than the reference levels. There was a statistically significant difference (P<.05) between the BMD values in the two sub-groups studied. DISCUSSION The greater the involvement, from a neurological point of view, in patients classified as Group V shows a very low BMD compared to patients of similar sex and age. The acquisition of bone capital in patients with ICP does not follow the normal pattern of the healthy population.
