Abstract
Purpose This report presents the long-term results of the hip joint reconstruction in patients with spastic hip disease through open reduction, proximal femur varus derotation osteotomy, and Dega transiliac osteotomy. Methods We analyzed retrospectively patients diagnosed with a spastic form of bilateral cerebral palsy with painful hip subluxation or dislocation. All patients underwent the same surgical procedure. The minimum follow-up time was 15 years. The study group comprised 15 patients (22 hips), classified with the Gross Motor Function Classification System as levels IV and V. The hip joint range of motion and anteroposterior X-ray examination at the final follow-up visit were compared with pre-operative data. The pain level was evaluated using the Visual Analogue Scale (VAS), and the femoral head shape was assessed using the Rutz classification. The patients' caregivers answered questions regarding pain during sitting, personal hygiene activities, and at rest. The caregivers' satisfaction with the treatment was also assessed with the Caregiver Priorities and Child Health Index of Life with Disabilities questionnaire. Results We observed a significant reduction of the hip joint pain and improvement in both radiological hip stability parameters and range of motion at the final follow-up visit. Based on the Rutz classification, one hip remained type B, while the other joints became type A. Reduced pain was reported in all three positions, with the most pronounced improvement during sitting and personal hygiene activities. Interestingly, patients with unilateral hip reconstruction were more prone to pain after reconstruction than those operated bilaterally. Conclusion Primary reconstruction of the painful hip joint neurogenic dislocation results in a stable joint reduction, pain decrease, and improved quality of life in patients with cerebral palsy. Level of evidence IV case series.

Abstract
AIM To systematically review the prevalence, risk factors and timing of onset of hip displacement in children with a post-neonatal (PNN) brain injury with regards to hip surveillance recommendations. METHOD A search of PubMed, MEDLINE, Embase, CINAHL and Web of Science was conducted on 22nd February 2022. Studies were included if they reported presence of, and risk factors for, hip displacement in children with PNN brain injury. Data was extracted on patient characteristics, and analyzed in terms of risk factors of interest and timing of development of hip displacement. RESULTS Six studies met the inclusion criteria (n = 408 participants). All were cohort studies: five retrospective and one prospective. Rates of hip displacement ranged from 1% to 100%, and were higher in children with diffuse brain injury at an early age, who were non-ambulant and had spastic quadriplegia. Hip displacement and hip dislocation were first identified at one and three months respectively following PNN brain injury. INTERPRETATION Evidence on hip displacement in children with PNN brain injury is sparse and low quality. Children who remain non-ambulant after diffuse PNN brain injury before five years of age appear most at risk of developing progressive hip displacement and earlier hip surveillance is recommended.

Abstract
BACKGROUND Hip displacement in children with cerebral palsy (CP) is monitored by measuring migration percentage on anteroposterior pelvis radiographs. However, proper positioning for radiography in children with spasticity is difficult. The reliability and accuracy of migration percentage as a function of patient positioning is unknown. OBJECTIVE To determine the effects of patient positioning on migration percentage measurements in children with CP. MATERIALS AND METHODS We identified children with CP (≤18-year-old) with pelvis CT and anteroposterior pelvis radiograph obtained <6 months apart (10/2018-11/2021). Digitally reconstructed radiographs were generated from each pelvis CT, to simulate nine different patient positions: neutral; 10° and 20° lordosis and kyphosis; and 10° and 20° right rotation and left rotation. Two radiologists measured migration percentages from the simulated and real pelvis radiographs. We used Spearman's rho to assess inter-rater reliability, and Wilcoxon signed rank test to determine statistical significance. RESULTS We studied sixty-three children (male=41; median age=8 years; range=4-18 years). The two radiologists' migration percentage measurements were highly correlated with each other across all simulated and real radiographs (Spearman's rho=0.86-0.99, P<0.01). For both readers and hips, migration percentages measured from real radiographs were significantly different from those measured from neutral simulated radiographs (P<0.01), with median absolute difference=5-6 percentage points (PP) and interquartile range (IQR)=9-12 PP. When comparing migration percentage measurements from neutral simulated radiographs to those in kyphosis/lordosis and right/left rotations, median absolute differences were 2-4 PP (IQR=3-8 PP) and 4-15 PP (IQR=6-17 PP), respectively. CONCLUSION Inter-rater reliability of measured migration percentages is high, but accuracy decreases with patient positional changes.

Abstract
Our investigation aimed to assess the reliability of the femoral head shape classification system devised by Rutz et al . and observe its application in patients with cerebral palsy (CP) at different skeletal maturity levels. Four independent observers assessed anteroposterior radiographs of the hips of 60 patients with hip dysplasia associated with non-ambulatory CP (Gross Motor Function Classification System levels IV and V) and recorded the femoral head shape radiological grading system as described by Rutz et al . Radiographs were obtained from 20 patients in each of three age groups: under 8 years, between 8 and 12 years and above 12 years old, respectively. Inter-observer reliability was assessed by comparing the measurements of four different observers. To determine the intra-observer reliability, radiographs were reassessed after a 4-week interval. Accuracy was checked by comparing these measurements with the assessment of expert consensus. Validity was checked indirectly by observing the relationship between the Rutz grade and the migration percentage. The Rutz classification system's evaluation of femoral head shape showed moderate to substantial intra- and inter-observer reliability (mean κ = 0.64 for intraobserver and mean κ = 0.5 for interobserver). Specialist assessors had slightly higher intra-observer reliability than trainee assessors. The grade of femoral head shape was significantly associated with increasing migration percentage. Rutz's classification was shown to be reliable. Once the clinical utility of this classification can be established, it has the potential for broad application for prognostication and surgical decision-making and as an essential radiographic variable in studies involving the outcomes of hip displacement in CP. Level of evidence: III.

Abstract
Objective Spastic hip dysplasia is a common complication of cerebral palsy in children, and surgical intervention is usually warranted. While current literature has primarily analyzed single institution outcomes, this study utilized a national database to describe readmission rates and factors correlated with readmission for children with cerebral palsy undergoing hip surgery in order to treat this population more effectively. Methods This study queried the Nationwide Readmissions Database (2014-2018) for pediatric patients with cerebral palsy who underwent hip surgery. Patient demographics, pre-operative comorbidities, length of stay (LOS), treatment complications, and readmission data were collected for each patient and analyzed with inferential statistics. Results Of the 1225 patients included, the average age was 9.3 ± 3.8 years and 42.8% were female. Approximately 26.3% patients had a prolonged LOS (≥5 days) and 14.2% patients required readmission within 90-days of surgery. Medical complications, cardiac arrhythmias, and iron deficiency anemia were all significantly associated with elongated LOS as well as 90-day readmission. Patients with Medicaid were more frequently associated with an inpatient medical complication and the overall complication rate was 5.5%. Conclusions While current literature has analyzed common risk factors and complications associated with hip surgery in the pediatric cerebral palsy patient, this study identifies a national readmission rate (14.2%) as well as preoperative comorbidities associated with readmission within 90-days and/or elongated LOS. Notably, complications are more frequently associated with patients using Medicaid. These results further exemplify the importance of equitable access to care and thorough selection of pediatric cerebral palsy patients appropriate for hip surgery.

Abstract
Hip displacement is the second most common musculoskeletal deformity in children with cerebral palsy. Hip surveillance programs have been implemented in many countries to detect hip displacement early when it is usually asymptomatic. The aim of hip surveillance is to monitor hip development to offer management options to slow or reverse hip displacement, and to provide the best opportunity for good hip health at skeletal maturity. The long-term goal is to avoid the sequelae of late hip dislocation which may include pain, fixed deformity, loss of function and impaired quality of life. The focus of this review is on areas of disagreement, areas where evidence is lacking, ethical dilemmas and areas for future research. There is already broad agreement on how to conduct hip surveillance, using a combination of standardised physical examination measures and radiographic examination of the hips. The frequency is dictated by the risk of hip displacement according to the child's ambulatory status. Management of both early and late hip displacement is more controversial and the evidence base in key areas is relatively weak. In this review, we summarise the recent literature on hip surveillance and highlight the management dilemmas and controversies. Better understanding of the causes of hip displacement may lead to interventions which target the pathophysiology of hip displacement and the pathological anatomy of the hip in children with cerebral palsy. We have identified the need for more effective and integrated management from early childhood to skeletal maturity. Areas for future research are highlighted and a range of ethical and management dilemmas are discussed.

Abstract
AIM In children with neurological complex chronic conditions (CCC) undergoing hip surgery we aimed to: estimate the rate of postoperative pneumonia, determine the effect of pneumonia on postoperative hospital resource use, and identify predictors of postoperative pneumonia. METHOD A retrospective cohort study was conducted utilizing the Pediatric Health Information System database for 2609 children (1081 females, 1528 males) aged 4 years and older with a neurological CCC who underwent hip surgery (i.e. reconstruction surgery or salvage procedure) between 2016 and 2018 in 41 US children's hospitals. Multivariable, mixed-effects logistic regression was used to assess patient characteristics and risk of pneumonia. RESULTS Mean age at hip surgery was 10 years 1 month (SD 4y 8mo). The postoperative pneumonia rate was 1.6% (n=42). Median length of stay (LOS) was longer for children with pneumonia and the 30-day all-cause unplanned readmission rate and costs were higher. Variability in rates of pneumonia ranged from 1.1% to 2.8% across hospitals. Significant predictors of postoperative pneumonia were osteotomy type (p=0.005) and number of chronic conditions (p≤0.001). INTERPRETATION Postoperative pneumonia after hip surgery in children with a neurological CCC is associated with longer LOS, readmissions, and higher costs. Children undergoing pelvic osteotomies and who have multimorbidity need additional clinical support to prevent postoperative pneumonia and decrease resource utilization. WHAT THIS PAPER ADDS Pneumonia is a major postoperative complication in children with neurological complex chronic conditions (CCC). Forty-two (1.6%) children with neurological CCC developed pneumonia after hip surgery. Length of stay, readmissions, and costs were significantly higher in the group with pneumonia. Variability in pneumonia rates existed across hospitals. Predictors of developing pneumonia include osteotomy type and number of CCC.

Abstract
Amaç: Bu çalışmada Spastik tip serebral palsi (SP) tanılı hastalarda kalça instabilitesi nedeniyle açık addüktör tenotomi (AT) yapılanlar ile addüktör kaslara Botulinum toksin-A (BTX-A) enjeksiyonu yapılanların klinik ve radyolojik sonuçlarının değerlendirilmesi ve karşılaştırılması amaçlanmıştır.
Gereç ve Yöntem: Hem AT grubunda hem de BTX-A grubunda kalça ve diz eklemleri tam ekstansiyonda iken maksimum kalça abdüksiyon açısı (MKAA) ölçüldü. MKAA’nın işlem öncesi değerleri ile son klinik muayenede elde edilen değerleri karşılaştırıldı. Bu ölçüme ek olarak AT grubunda kalça radyografileri üzerinde Reimers migrasyon yüzdesi (RMY) ölçüldü.
Bulgular: AT grubunda 30 (ortalama yaş: 8.3), BTX grubunda ise 25 (ortalama yaş: 5.9) hasta mevcuttu. Ortalama takip süresi AT grubunda 29.6 ay idi. AT grubunda ameliyat öncesi muayenede ve son muayenede ölçülen MKAA değerleri sırasıyla 21.20 ve 37.10 idi. BTX-A grubunda enjeksiyon öncesi muayenede ve son muayenede ölçülen MKAA değerleri sırasıyla 25.30 ve 34.20 idi. MKAA değerinin değişim miktarı ortalaması AT grubunda 16.20, BTX-A grubunda ise 8.80 idi. AT grubunda ameliyat öncesi RMY ortalaması %28.2, son muayene ortalaması ise %22.2 idi.
Sonuç: Hem AT grubunda hem de BTX-A grubunda kalça abdüksiyon açıları anlamlı düzeyde artmasına rağmen AT grubunda bu artış BTX-A grubuna kıyasla daha fazla olmaktadır. Ek olarak AT grubunda radyolojik olarak belirgin düzelme gözlenmektedir.

Abstract
Purpose This study aims to compare radiographic outcomes and complication rates of immobilization with an abduction pillow to spica casting for postoperative care after a hip reconstruction with varus derotational proximal femur osteotomy (VDRO) with or without pelvic osteotomy for children with cerebral palsy (CP). Methods 233 children (1–18 years old) diagnosed with CP that underwent VDRO with or without pelvic osteotomy were identified, of which 188 patients were immobilized with a spica cast and 45 were immobilized with an abduction pillow, based on surgeon preference. 123 (65%) in the Spica group and 21 (47%) in the pillow group had pelvic osteotomies. Demographic data and complication rates were collected. Radiographic parameters, including anatomic medial proximal femoral angle (aMPFA), acetabular index (AI) and migration percentage (MP), were measured for each patient at the completion of surgery, six weeks post-operatively, and one year post-operatively. Results There was not a statistically significant difference in BMI (p = 0.285), gender distribution (p = 0.984), or median follow-up time (p = 0.314) between groups. Rates of complications were consistent among groups with no differences in instances of delayed unions (p = 0.10), subluxations (p = 0.55), infection (p = 0.71), or non-unions (p = 0.10). There was no statistically significant difference in number of patients with an ideal aMPFA, AI, or MP (p = 0.44, p = 0.19, p = 1.00) at one year post-operatively. Conclusions Immobilization with an abduction pillow is a safe and effective alternative to hip spica casting following hip reconstruction.

Abstract
Background Cerebral Palsy is the leading cause of childhood physical disability globally. The motor disorders of CP are often associated with musculoskeletal anomalies, of which hip displacement is the second most common abnormality after abnormalities of foot and ankle. Various radiological parameters have been described in the literature which detects and quantifies hip dysplasia, with MP being the current gold standard. This study aims to review these radiological indicators of hip dysplasia in children with cerebral palsy from the published literature. Methods A literature search using PubMed, Embase, and Google Scholar was done on 15th June 2021 focusing on surveillance of hip dysplasia in cerebral palsy. The studies to be included were to have used anyone or more radiological parameter for detection of hip dysplasia with the use of any of the radiological methods. Results The initial search yielded 1184 results. After the screening of the abstracts and full texts, a final of 30 studies was included for this systematic review. The majority of the studies were graded as Level 3 evidence (16/30), followed by Level 2 studies (14/30). X-ray was the most common modality of detection of dysplasia followed by CT scan, ultrasonography, and arthrogram. The reproducibility of the various parameters shows good to excellent intraclass coefficients. Conclusions Parameters other than MP can be used to screen hips in CP. This would be useful in patients in whom either the lateral acetabular edge is not discernible on a plain anteroposterior radiograph or there are issues in the positioning of the patient. Additional views and structures can be visualized which can lead to improved screening and planning. Further investigations are required to appreciate the full potential of these parameters and how they can be better utilized. Graphical abstract

Abstract
Objective To investigate the practice patterns of Canadian physicians who use perioperative botulinum toxin (BoNT) injections to improve surgical outcomes on spastic limbs. Design A cross-sectional national survey composed of an invitation email and an 18-item questionnaire was disseminated by a national physical medicine and rehabilitation (PMR) society to 138 physician members involved in spasticity management. Setting Not applicable. Participants Twenty-five percent of the participants (N=34) fully completed the survey. Interventions Not applicable. Main Outcome Measures Participants completed an online questionnaire that examined the practice patterns and surgical outcomes associated with perioperative BoNT injections. Results The majority (n=21; 84%) of Canadian physicians who inject BoNT perioperatively to improve outcomes of surgeries performed on spastic limbs are specialists in PMR practicing in academic settings. Most respondents (74%) used BoNT injections for perioperative treatment for patients with limb spasticity undergoing surgery. Of those surveyed, 65% of physicians used BoNT preoperatively, 21% used BoNT intraoperatively, and 24% used BoNT postoperatively.Of the physicians who performed BoNT injections preoperatively, 6% performed BoNT injections 7 to 12 weeks preoperatively, 32% performed BoNT injections 4 to 6 weeks preoperatively, 47% performed BoNT injections 2 to 3 weeks preoperatively, and 15% performed BoNT injections 0 to 1 week preoperatively. The majority of physicians (85%) responded that injecting BoNT perioperatively may improve a patient's surgical outcome and all of the participants (100%) stated that BoNT did not contribute to any perioperative complications or adverse effects. Qualitative responses emphasized that successful outcomes from the perioperative BoNT were linked to enhanced collaboration with surgeons and that more research is needed to determine the optimal timing of perioperative BoNT. Conclusion Canadian physicians, mostly PMR specialists, administer perioperative BoNT to improve outcomes of surgeries performed on spastic limbs. The optimal timing for perioperative BoNT was suggested to be 2 to 3 weeks before the surgery by 47% of survey respondents. All participating physicians responded that perioperative BoNT did not contribute to any known perioperative complications or adverse events. This study highlights the importance of conducting more robust research to better understand optimal timing for perioperative BoNT injection, enhancing collaboration between physicians and surgeons, and increasing awareness of perioperative BoNT when planning for surgeries on spastic limbs.

Abstract
Hip dysplasia, subluxation, and eventual hip dislocation are commonly encountered in the cerebral palsy population secondary to spasticity and loss of motor control, especially in those patients with more severe neurologic involvement. The treatment of hip disorders in these patients should take into account the degree of limb and hip involvement, pain severity, and overall functioning. Conservative management focuses on mitigating spasticity and preserving range of motion in order to provide an environment in which the femoral head remains concentrically reduced in the acetabulum. However, operative management, consisting of soft tissue or tendon releases, femoral or pelvic osteotomies, or hip salvage procedures, is sometimes necessary to treat the painful, subluxated, or dislocated hip. Radiographic hip surveillance in the pediatric cerebral palsy population is used to guide operative treatment. Long term hip containment is generally improved when surgical intervention is performed in the earlier stages of dysplasia. Younger patients who demonstrate progressive hip subluxation despite conservative measures may be carefully selected to undergo soft tissue procedures. Bony reconstruction, with adjunctive soft tissue procedures, is often necessary to better contain the proximal femur in patients above the age of four years.

Abstract
INTRODUCTION Research and continuous quality improvement in pediatric rehabilitation settings require standardized data and a systematic approach to use these data. METHODS We systematically examined pediatric data concepts from a pediatric learning network to determine capacity for capturing gross motor function (GMF) for children with Cerebral Palsy (CP) as a demonstration for enabling infrastructure for research and quality improvement activities of an LHS. We used an iterative approach to construct phenotype models of GMF from standardized data element concepts based on case definitions from the Gross Motor Function Classification System (GMFCS). Data concepts were selected using a theory and expert-informed process and resulted in the construction of four phenotype models of GMF: an overall model and three classes corresponding to deviations in GMF for CP populations. RESULTS Sixty five data element concepts were identified for the overall GMF phenotype model. The 65 data elements correspond to 20 variables and logic statements that instantiate membership into one of three clinically meaningful classes of GMF. Data element concepts and variables are organized into five domains relevant to modeling GMF: Neurologic Function, Mobility Performance, Activity Performance, Motor Performance, and Device Use. CONCLUSION Our experience provides an approach for organizations to leverage existing data for care improvement and research in other conditions. This is the first consensus-based and theory-driven specification of data elements and logic to support identification and labeling of GMF in patients for measuring improvements in care or the impact of new treatments. More research is needed to validate this phenotype model and the extent that these data differentiate between classes of GMF to support various LHS activities.

Evaluating Completeness of Discrete Data on Physical Functioning for Children With Cerebral Palsy in a Pediatric Rehabilitation Learning Health System. Phys Ther 2022; 102:6380791. [PMID: 34636905 DOI: 10.1093/ptj/pzab234] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 07/06/2021] [Accepted: 09/06/2021] [Indexed: 11/14/2022]
Abstract
OBJECTIVE The purpose of this study was to determine the extent that physical function discrete data elements (DDE) documented in electronic health records (EHR) are complete within pediatric rehabilitation settings. METHODS A descriptive analysis on completeness of EHR-based DDEs detailing physical functioning for children with cerebral palsy was conducted. Data from an existing pediatric rehabilitation research learning health system data network, consisting of EHR data from 20 care sites in a pediatric specialty health care system, were leveraged. Completeness was calculated for unique data elements, unique outpatient visits, and unique outpatient records. RESULTS Completeness of physical function DDEs was low across 5766 outpatient records (10.5%, approximately 2 DDEs documented). The DDE for Gross Motor Function Classification System level was available for 21% (n = 3746) outpatient visits and 38% of patient records. Ambulation level was the most frequently documented DDE. Intercept only mixed effects models demonstrated that 21.4% and 45% of the variance in completeness for DDEs and the Gross Motor Function Classification System, respectively, across unique patient records could be attributed to factors at the individual care site level. CONCLUSION Values of physical function DDEs are missing in designated fields of the EHR infrastructure for pediatric rehabilitation providers. Although completeness appears limited for these DDEs, our observations indicate that data are not missing at random and may be influenced by system-level standards in clinical documentation practices between providers and factors specific to individual care sites. The extent of missing data has significant implications for pediatric rehabilitation quality measurement. More research is needed to understand why discrete data are missing in EHRs and to further elucidate the professional and system-level factors that influence completeness and missingness. IMPACT Completeness of DDEs reported in this study is limited and presents a significant opportunity to improve documentation and standards to optimize EHR data for learning health system research and quality measurement in pediatric rehabilitation settings.

Abstract
Children with a neurological disorder such as cerebral palsy (CP) severely suffer from a reduced quality of life because of decreasing independence and mobility. Although there is no cure yet, a lower-limb exoskeleton (LLE) has considerable potential to help these children experience better mobility during overground walking. The research in wearable exoskeletons for children with CP is still at an early stage. This paper shows that the number of published papers on LLEs assisting children with CP has significantly increased in recent years; however, no research has been carried out to review these studies systematically. To fill up this research gap, a systematic review from a technical and clinical perspective has been conducted, based on the PRISMA guidelines, under three extended topics associated with "lower limb", "exoskeleton", and "cerebral palsy" in the databases Scopus and Web of Science. After applying several exclusion criteria, seventeen articles focused on fifteen LLEs were included for careful consideration. These studies address some consistent positive evidence on the efficacy of LLEs in improving gait patterns in children with CP. Statistical findings show that knee exoskeletons, brushless DC motors, the hierarchy control architecture, and CP children with spastic diplegia are, respectively, the most common mechanical design, actuator type, control strategy, and clinical characteristics for these LLEs. Clinical studies suggest ankle-foot orthosis as the primary medical solution for most CP gait patterns; nevertheless, only one motorized ankle exoskeleton has been developed. This paper shows that more research and contribution are needed to deal with open challenges in these LLEs.

Abstract
BACKGROUND Methyl-CpG binding protein 2 (MECP2) disorders, including Rett syndrome and MECP2 duplication syndrome, are typified by profound intellectual disability, spasticity, and decline in gross motor function. Unlike scoliosis, linked to disease severity, little has been reported regarding the hip. The aim of this study was to report the prevalence and risk factors of hip displacement (HD) in MECP2 disorders. METHODS This was a retrospective, comparative study. Children with a genetically confirmed MECP2 disorder were included. The primary outcome measure was the prevalence of HD (migration percentage>30%). Secondary outcomes included age at HD onset, ambulatory status, presence of clinically relevant scoliosis, genetic severity, presence of seizures, and associated comorbidities. Analysis of proportions of categorical variables was performed using χ2 testing (P=0.05). RESULTS Fifty-six patients (54 Rett syndrome and 2 MECP2 duplication syndrome), diagnosed at 6.6 (SD: 4.7) years, met the inclusion criteria. The prevalence of HD was 36% [onset, 7.7 (SD: 3.8) y]. Risk factors for HD were nonwalker status (P=0.04), scoliosis (P=0.001), and refractory epilepsy (P=0.04). CONCLUSIONS The prevalence of HD in MECP2 disorders is comparable to cerebral palsy, associated with proxy measures of disease severity. These results can be used to develop hip surveillance programs for MECP2 disorders, allowing for timely management. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND The purpose of this study was to assess Indian orthopaedic surgeons' current practices and beliefs regarding hip surveillance for children with cerebral palsy (CP), to determine potential support for developing hip surveillance guidelines, and to identify knowledge gaps and key obstacles to guideline implementation in India. METHODS An anonymous, cross-sectional online survey was sent to approximately 350 Paediatric Orthopaedic Society of India (POSI) members who were queried on their practices and beliefs about hip surveillance for children with CP, as well as perceived challenges and requirements for the successful implementation of hip surveillance guidelines in the Indian context. RESULTS Out of 107 responses obtained from POSI members, almost all (96.2%) agreed that hip displacement requires standardized monitoring, using surveillance and surgery to prevent hip dislocation. Approximately half (51.5%) of respondents reported using existing hip surveillance guidelines, with most (41.2%) using the Australian guidelines. Almost all (97%) surgeons indicated that hip surveillance guidelines in India are needed, with 100% expressing interest in following guidelines specific to India. Respondents most frequently indicated late referrals to orthopaedics (81.2%), loss of patients to follow-up (78.2%), and lack of resources (43.6%) as challenges to successful hip surveillance in India. Perceived requirements for implementation included developing Indian-specific guidelines (83.2%) as well as educating surgeons (56.4%), physiotherapists/pediatricians (90.1%), and families (82.2%). CONCLUSION Orthopaedic surgeons practicing in India understand the importance of preventing hip dislocations in children with CP through hip surveillance and timely surgical intervention. The results demonstrated strong support for the development of hip surveillance guidelines designed specifically for the Indian healthcare system.

Abstract
Our objective was to systematically review literature regarding the rationale and current evidence for peri-operative Botulinum Neurotoxin (BoNT) injection to improve outcomes of surgeries on spastic limbs. We conducted a systematic search of databases MEDLINE, EMBASE, and Cochrane Central Register of Controlled until March 2020, using the PRISMA guidelines. After assessing all titles and abstracts against inclusion criteria, full texts were reviewed for studies of potential interest. The inclusion criteria were studies on humans with any study design, published in all languages. Participants had to have underlying limb spasticity and be scheduled to undergo surgery on one or more spastic limb(s). BoNT had to be administered peri-operatively to improve surgical outcomes and not solely for the purpose of alleviating spasticity. The risk of bias was evaluated using the Physiotherapy Evidence Database (PEDro) scoring system for randomized controlled trials (RCTs) and the Downs and Black tool for RCTs and non-randomized trials. Further, the level of evidence was evaluated using a five-level scale (simplified form of Sackett). Five studies met our inclusion criteria comprising a total of 90 participants, of both pediatric and adult age groups, with underlying limb spasticity, who received BoNT perioperatively to improve outcomes of the surgeries performed on spastic limbs. Interventions were intramuscular BoNT injection prior to, at the time of, or after surgery on a spastic limb for the purpose of improving surgical outcomes, and not solely for alleviating muscle spasticity. Outcome measures were surgical success/failure, post-operative pain and analgesic use, sleep quality, adverse events, spasticity control e.g. Modified Ashworth Scale. Our literature search yielded 5 articles that met the inclusion criteria. Current evidence supports peri-operative injection of BoNT to improve outcomes of surgeries performed on spastic limbs. There is level 1 evidence that BoNT administered pre-operatively is effective for reducing pain, spasticity, and analgesic use in pediatric patients with cerebral palsy (CP). This is supported by level 4 evidence from a retrospective case series. Level 5 evidence from case reports highlights the potential for the use of BONT in the peri-operative period. There is level 1 evidence that BoNT administered intra-operatively is not effective for reducing pain and analgesic use in pediatric patients with CP. This lack of benefit may reflect sub-optimal timing of injections, different methods of injection, different timing of the primary outcome measure, and/or differences in adjunctive therapies, but further research is required.

Abstract
INTRODUCTION Reimers migration percentage (MP) is the gold standard for measuring hip displacement in children with cerebral palsy (CP). Hip surveillance registries proposed using the top of the Gothic arch (GA) as a modification in patients with acetabular dysplasia because the classical method (CM) described by Reimers may underestimate hip migration. The aim of this study is to assess the inter- and intra-observer reliability of the modified method (MM) versus the CM and identify their effect on the MP. METHODS We performed a retrospective review of 50 children with CP, who had a hip radiograph at our institution between 1st April 2014 and 28th February 2018. All hip radiographs were carefully selected to show the presence of a GA. Four observers measured the MP using the CM and MM for each patient. Interclass coefficient was used to estimate inter- and intra-observer reliability. RESULTS Inter-observer reliability was excellent for the CM with ICC 0.96 (95% CI 0.94 to 0.97) and good for the MM, ICC 0.78 (95% CI 0.51 to 0.89) p < 0.001. Intra-observer reliability was excellent for both methods raging from ICC 0.94 to 0.99 for the CM and ICC 0.89 to 0.95 for the MM. The mean MP was 19% for the CM and 28% for the MM (p < 0.001). CONCLUSION The CM is more reliable than the MM to measure hip migration in children with CP. If the CM is used and acetabular dysplasia with a GA are present on the hip radiograph, then a 9% hip migration underestimation should be considered on decisions for both referral and surgical management.

Abstract
Cerebral palsy (CP) is the leading cause of physical disability in children. Although physical disability is the hallmark of CP, children with CP also often have complex medical comorbidities. Spastic hip subluxation is the second most common orthopaedic deformity in children with CP, and the incidence increases with the severity of CP. Hip surveillance should be implemented in children with CP to monitor hip stability over time. A reconstructive surgical procedure is recommended when the migration percentage is >40%. Perioperative care of children undergoing a hip reconstructive surgical procedure is a multidisciplinary endeavor requiring the expertise of professionals with different backgrounds. The core team should comprise orthopaedic surgeons, nurses, nurse practitioners, pediatricians, nurse case managers, anesthesiologists, and physical therapists. Additional team members include nutritionists, clinical pharmacists, social workers, child life therapists, and consulting specialty services. This review describes the team approach to the perioperative care of non-ambulatory children with spastic hip subluxation undergoing a reconstructive hip surgical procedure, utilizing a case scenario of a 7-year old girl with CP and complex associated medical comorbidities.

Abstract
Background Hip dysplasia is common among children with cerebral palsy (CP), particularly in spastic CP. It can result in pain, reduced function and quality of life. However, the burden of hip dysplasia among children with CP in llow-and middle-income countries (LMICs) like Bangladesh is unknown. We aimed to define the burden of hip dysplasia among children with spastic CP in Bangladesh. Methods This study includes a subset of the Bangladesh CP Register (BCPR) study cohort who were registered between January and March 2015. The BCPR is a population-based surveillance of children with CP (aged < 18 years) operating in a northern sub-district (Shahjadpur; child population ~ 226,114) of Bangladesh. Community-based key informant’s method (KIM) survey conducted to identify children with CP in the surveillance area. A diagnosis of CP was made based on clinical history and examination by the study physicians and physiotherapist. Study participants had an antero-posterior (AP) X-ray of their pelvis. The degree of subluxation was assessed by calculating the migration percentage (MP). Results During the study period, 196 children with CP were registered, 144 had spastic CP. 40 children with spastic CP (80 hips) had pelvic X-Rays (mean age 9.4 years, range 4.0–18.0 years) and 32.5% were female. Gross Motor Function Classification System (GMFCS) showed 37.5% (n = 15) with GMFCS level I-II and 62.5% (n = 25) with GMFCS level III-V. Twenty percent (n = 8) of the children had hip subluxation (MP: 33–80%). Osteopenic changes were found in 42.5% (n = 17) children. Conclusions To the best of our knowledge this is one of the first studies exploring hip dysplasia among children with spastic CP in Bangladesh. Our findings reflect that hip dysplasia is common among children with spastic CP. Introduction of hip surveillance programmes is imperative for prevention of secondary complications, reduced function and poor quality of life among these children.

Abstract
OBJECTIVES Cerebral palsy (CP) increases the risk of hip displacement during childhood. Abnormal hip muscle forces have been proposed as the predisposing factors. In CP, the amount of hip displacement is commonly evaluated by the Reimers hip migration index (MI) on an anteroposterior pelvic radiograph. To the best of our knowledge, the association between the elasticity of hip muscles measured by shear wave elastography and the MI has not been studied yet. Herein, we aimed to analyze the correlation between the elasticity of hip muscles and the MI. METHODS Bilateral hips of 25 children with spastic CP were included prospectively in this study. Anteroposterior pelvic radiographs were used to measure the MI. Shear wave elastography was performed to evaluate the elasticity of muscles. The correlation between the MI and the elasticity of hip flexor and adductor muscle groups was assessed. Also, the association between the elasticity of agonist/antagonist muscles was analyzed. RESULTS The MI showed fair to good correlations with hip flexors and adductors for both readers (0.71 ≥ r ≥ 0.52). The mean MIs of the patients ± SDs were 22.64% ± 7.79% for reader 1 and 21.55% ± 8.83% for reader 2. The elasticity of agonist/antagonist muscle groups showed little/no to a weak correlation for both readers (0.32 ≥ r ≥ -0.07). CONCLUSIONS Although, hip flexor and adductor muscle elasticity showed a correlation with MI, it seems very hard to say that increased elasticity of hip flexor and adductor muscles causes hip dislocation.

Abstract
BACKGROUND Heterotopic ossification (HO) is a well-recognized complication of proximal femoral resection (PFR) surgery in children with cerebral palsy (CP). Although single-dose radiation prophylaxis (SDRP) has been shown to be effective at lowering the rates of HO following adult total hip arthroplasty; there has been limited study examining the efficacy of SDRP for HO prevention in children with CP undergoing PFR. The purpose of this study was to assess the efficacy of SDRP in children with CP undergoing PFR. METHODS This retrospective case control series identified all patients from one tertiary children's hospital undergoing PFHR. Patients were dichotomized into (1) SDRP and (2) non-SDRP groups. In SDRP, radiation was delivered preoperatively at a dose of 7.5 Gy utilizing a 6 MV photon beam. The incidence of HO in the SDRP cohort was compared to historic data using binomial testing. The size of HO lesions was compared using Wilcoxon signed-rank test. McCarthy, Brooker, and Anatomic Classifications of HO were compared using repeated measures logistic regression. RESULTS Twenty-three patients (mean age, 15.5) and 35 hips (17 SDRP, 18 Non-SDRP) were included in the analysis. There were 17 females and 6 males in the cohort with the majority classified as GMFCS V, 21/23 (91%). HO was seen in 6 of the SDRP cohort (6/17, 35%) and 15 of the non-SDRP cohort (15/18, 83%) (P=0.015). The average size of HO at maturity was 282.7 mm in the SDRP cohort compared with 1221.5 mm in the Non-SDRP cohort (P=0.026). Radiation treatment was associated with a 938.9 mm decrease in HO size at maturity (P= 0.026). Multivariate repeated measures logistic regression analysis found that non-SDRP hips had 13 times higher odds of developing HO (P=0.015). There were no significant differences in infection rates between the 2 cohorts and there were no radiation-associated complications. CONCLUSIONS Short-term follow up demonstrates that SDRP is a safe and efficacious intervention in decreasing the incidence and size of HO in children with CP undergoing PFR.

Abstract
AIM To determine caregiver knowledge and preferences for gross motor information and examine differences across Gross Motor Function Classification System (GMFCS) levels. METHOD A questionnaire was developed. Respondents reported GMFCS knowledge, preference for knowledge, and experience with GMFCS and motor curve information. RESULTS In total, 303 caregivers of children with cerebral palsy (CP) (GMFCS level I: 22%; GMFCS level II: 16%; GMFCS level III: 15%; GMFCS level IV: 23%; GMFCS level V: 24%) completed the questionnaire. Forty-five per cent of caregivers knew the GMFCS level at survey, and only 31% knew how their child's motor development compared with others of similar age and level. Caregiver education level was associated with knowledge (p<0.001). Most prefer discussing motor development with a therapist. Of caregivers who knew their child's GMFCS level at survey, 83% reported it would be helpful to revisit the topic over time. Compared with GMFCS level IV and V, caregivers of children in GMFCS levels I to III preferred to learn at the same time as CP diagnosis, (p=0.04) and were more likely to report having received visual aids (p=0.04). Caregivers of children in GMFCS levels IV and V found it more difficult to learn their child's level (p<0.001) versus those caring for children of GMFCS levels I to III, and reported seeing pictures with descriptions more informative (p=0.03). INTERPRETATION Caregivers of children with CP may not know GMFCS and motor curve information, and vary in experience and preferences for this information. WHAT THIS PAPER ADDS Fewer than half of caregivers of children with cerebral palsy (CP) know their child's Gross Motor Function Classification System level. Most want to know how their child's function compares to other children with CP. The majority of caregivers would like to revisit the topic over time. Caregivers want to discuss gross motor information with the therapist and doctor.

Abstract
Optimal clinical decision making and surgical management of hip dysplasia in children with cerebral palsy (CP) requires an understanding of the underlying pathophysiology (pathomechanics and pathoanatomy), incidence, and natural history. The incidence of hip dysplasia in children with CP is directly related to the degree of motor impairment. A subluxated or dislocated hip in a child with CP can compromise the quality of life for both the child and their caregivers. The goal of this article is to highlight the events over the last 25 years that have had the greatest impact on the management of hip dysplasia in children with CP. It is my opinion that the 2 most significant advances during this time have been the development of a classification system based upon motor impairment (the Gross Motor Function Classification System), and the development of surveillance programs for hip dysplasia in children with CP. This article will contrast neuromuscular hip dysplasia with developmental dysplasia of the hip. It will be shown how the development and utilization of the Gross Motor Function Classification System has contributed to our understanding of the epidemiology and natural history of hip dysplasia in children with CP, and to the assessment of outcomes following surgical management. The impact of hip surveillance programs on early soft tissue surgeries, skeletal hip reconstructions, and the incidence of hip dislocations and salvage surgeries will be reviewed. Challenges in the implementation of hip surveillance programs in resource poor and decentralized health care delivery systems will be considered, and innovative approaches identified.

Abstract
PURPOSE Cerebral palsy (CP) is the most common motor disability of childhood. Less is known about its prevalence and associated factors in Switzerland, so we aimed to fill this knowledge gap in one Swiss canton, evaluating the feasibility to build up a CP registry. METHODS A retrospective review of medical records was undertaken. Children born during 1995 and 2009 in the canton of Saint Gallen diagnosed with CP were eligible for inclusion. RESULTS A total of 140 patients formed the study cohort. The prevalence of CP was 0.19%, with 85% of children affected by spastic CP. CONCLUSIONS The results of the present study were comparable with data of the Surveillance of Cerebral Palsy in Europe network. Moreover, this pilot study demonstrated the feasibility and usefulness of creating a registry of children affected by CP.

Abstract
The hip is the second most common involved joint in cerebral palsy. Hip displacement occurs in more than 33% of children with cerebral palsy, with a higher prevalence in nonambulatory children. Hip displacement in this population is typically progressive. Hip dislocation can result in pain and difficulty with sitting and perineal care. Since early stage of hip displacement can be silent, and hip surveillance programs are recommended. Most programs use the degree of hip dysplasia and Growth Motor Function Classification System level for screening recommendations. Treatment depends on the degree of dysplasia, functional status of the patient, and patient's age.

Abstract
BACKGROUND Currently, hip surveillance programs for children with cerebral palsy exist in Europe, Australasia, and parts of Canada, but a neuromuscular hip surveillance program has yet to be adopted in the United States. The purpose of this study was to report the current orthopaedic practice of hip surveillance in children with cerebral palsy, identify areas of practice variation, and suggest steps moving forward to generate guidelines for national neuromuscular hip surveillance. METHODS The entire membership of the Pediatric Orthopaedic Society of North America (POSNA) was surveyed in 2016 for information regarding their practice for hip surveillance in children with cerebral palsy. Detailed information regarding timing, frequency, and practice of hip surveillance was obtained in answers to 26 different questions. RESULTS A survey response rate of 27% was obtained (350/1300 members) during the study period. The majority of respondents treated pediatric patients exclusively (97%), worked in an academic practice (70%), and was affiliated with a university (76%). In total, 18% (69/350) of respondents followed a regular cerebral palsy hip surveillance program, about half of whom (44%, 30/69) had adopted the Australian guidelines. Respondents agreed that a dislocated hip in a child with cerebral palsy was painful (90% agreement) and should be prevented by hip surveillance (93% agreement). Furthermore, 93% of respondents indicated they would follow a national surveillance program if one was in place. Age (79%), Gross Motor Function Classification System (81%), and migration percentage (MP) (78%) were all identified as critical elements to a hip surveillance program. The majority of respondents felt that a hip "at risk" for hip displacement had a MP between 20% and 30% (57% of respondents), whereas surgery should be utilized once the MP exceeded 40% (50% of respondents). CONCLUSIONS Results from this survey demonstrate 90% of respondents agree that a dislocated hip could be painful and 93% would follow a national surveillance program if available. At a societal level, we have the ability to standardize cerebral palsy hip surveillance, thereby decreasing practice variation and improving quality of care delivery. LEVELS OF EVIDENCE Level V.

Abstract
AIM Acetabular dysplasia is the one of main causes of hip displacement in patients with cerebral palsy (CP). Although several studies have shown a relationship between hip displacement and acetabular dysplasia, relatively few have evaluated the association between quantitative acetabular dysplasia and related factors, such as Gross Motor Function Classification System (GMFCS) level. METHOD We performed a morphometric analysis of the acetabulum in patients with CP using multiplanar reformation of computed tomography data. The three directional acetabular indices (anterosuperior, superolateral, and posterosuperior) were used to evaluate acetabular dysplasia. Consequently, linear mixed-effects models were used to adjust for related factors such as age, sex, GMFCS level, and migration percentage. RESULTS A total of 176 patients (mean age 9y 5mo, range 2y 4mo-19y 6mo; 104 males, 72 females) with CP and 55 typically developing individuals (mean age 13y 6mo, range 2y 5mo-19y 10mo; 37 males, 18 females) in a comparison group were enrolled in this study. Statistical modelling showed that all three directional acetabular indices independently increased with GMFCS level (p<0.001) and migration percentage (p<0.001). INTERPRETATION Acetabular dysplasia was independently affected by both the amount of hip displacement and the GMFCS level. Thus, physicians should consider not only the migration percentage but also three-dimensional evaluation in patients at high GMFCS levels.

Abstract
UNLABELLED This study investigated the degree of acetabular and femoral remodeling after isolated varus derotation osteotomy (VDRO) in children with cerebral palsy. This retrospective review investigated 56 children (103 hips) who underwent VDROs for spastic hip displacement between 1994 and 2007. The average age of the patients at surgery was 7.7 years and the follow-up duration was 7.8 years (range 5-11 years). The acetabular index showed a significant linear decrease (P<0.001), with children of less than 6 years showing the greatest correction (P<0.001). VDRO without pelvic osteotomy does result in a mild improvement in acetabular dysplasia over time, with greater rates of correction found in children of less than 6 years old.

Abstract
Pelvic obliquity is a common finding in adolescents with cerebral palsy, however, there is little agreement on its measurement or relationship with hip development at different gross motor function classification system (GMFCS) levels. The purpose of this investigation was to study these issues in a large, population-based cohort of adolescents with cerebral palsy at transition into adult services. The cohort were a subset of a three year birth cohort (n = 98, 65M: 33F, with a mean age of 18.8 years (14.8 to 23.63) at their last radiological review) with the common features of a migration percentage greater than 30% and a history of adductor release surgery. Different radiological methods of measuring pelvic obliquity were investigated in 40 patients and the angle between the acetabular tear drops (ITDL) and the horizontal reference frame of the radiograph was found to be reliable, with good face validity. This was selected for further study in all 98 patients. The median pelvic obliquity was 4° (interquartile range 2° to 8°). There was a strong correlation between hip morphology and the presence of pelvic obliquity (effect of ITDL on Sharpe's angle in the higher hip; rho 7.20 (5% confidence interval 5.59 to 8.81, p < 0.001). This was particularly true in non-ambulant adolescents (GMFCS IV and V) with severe pelvic obliquity, but was also easily detectable and clinically relevant in ambulant adolescents with mild pelvic obliquity. The identification of pelvic obliquity and its management deserves closer scrutiny in children and adolescents with cerebral palsy.

Abstract
[Purpose] Reimers’ hip migration percentage (MP) is commonly used to document the extent
of hip displacement in children with cerebral palsy (CP). However, factors such as poor
administration of pelvic radiographs, a lack of concentration, inexperience, or a busy
clinical environment may result in variations in the MP measurements. The aim of this
study was to compare the differences in the MP results of two physiatrists with varying
levels of experience to determine the role of experience in the measurement’s accuracy.
[Subjects and Methods] This retrospective study included 62 hip radiographs of 31 children
with spastic CP. Two physiatrists with different experience levels calculated the baseline
MP on two occasions six weeks apart. Correlations, intra- and inter-rater reliabilities,
and differences in the MPs were compared. [Results] Correlations and inter- and
intra-rater reliabilities of the measurements were excellent. There were no statistically
significant intra- or inter-rater differences for either of the two measurement points.
Inter-rater correlations for each session were 0.94. [Conclusion] Experience does not
appear to be a factor in the evaluation of MP, and inter-rater differences do not cause
problems regarding patient follow-up. Therefore, repeated pelvic radiographs are not
necessary in the evaluation of MP in children with CP unless indicated.

Abstract
AIM To explore the provision and variations in care for children and young people with cerebral palsies (CP) registered with the population-based North of England Collaborative Cerebral Palsy Survey (NECCPS). METHOD This is a retrospective multicentre record audit of 389 children with CP (220 males, 148 females, 21 no data; median age at time of audit 12y 3mo), born between 1995 and 2002. Data were collected on cranial magnetic resonance imaging (MRI), hip and spine surveillance and management, and pain presence and management. Variations over time and between the districts in the north of England (Northumberland, North and West Cumbria, North and South Tyneside, Newcastle-upon-Tyne, Gateshead, Sunderland, Durham, Darlington, Bishop Auckland, Hartlepool, Stockton-on-Tees, Middlesbrough, Redcar, and Cleveland), and by socio-economic status (SES) (estimated from the Index of Multiple Deprivation [IMD] 2004) were estimated by generalized estimating equations. RESULTS There was significant variation between districts in access to MRI (p<0.001), orthopaedic surgeons (p=0.005), recording state of spine (p<0.001), and discussions about pain (p<0.001). Fifty-seven per cent (95% CI 52-62) had evidence of a reported MRI brain scan, the proportion of which increased over time (p<0.001). Sixty-seven per cent (95% CI 62-71) had a discussion about pain recorded. Of those in pain, 87% (95% CI 80-93) had a pain management plan. The proportion with documented discussion about pain increased with increasing SES (p=0.04). INTERPRETATION The provision of care for children with CP in the north of England varies between districts. Internationally agreed, evidence-based standards are urgently needed to ensure more equitable health care and improved outcomes for all.

Abstract
Hip subluxation is common in children with spastic cerebral palsy. Most physicians favor intervention to treat hip subluxation in skeletally immature patients with cerebral palsy. However, treatment in skeletally mature patients with cerebral palsy is controversial. The goal of this study was to evaluate radiographic and clinical outcomes after hip reconstruction in skeletally mature patients with cerebral palsy. The authors performed a retrospective review of all skeletally mature patients (n=20) with cerebral palsy who underwent hip surgery for subluxation at the authors' institution between 2005 and 2011. Charts were reviewed for demographic characteristics, procedure, follow-up, and complications. Acetabular index, migration index, and neck-shaft angle were measured on preoperative and most recent radiographs. Average follow-up was 2.2 years. Average migration index for the entire group improved from 57% to 20% (P<.0001). Of patients who had all radiographic abnormalities addressed at surgery (varus derotational femoral osteotomy for neck-shaft angle >135°, open reduction for migration index >50%, and acetabular osteotomy for acetabular index >25°), 91% had a final migration index of less than 25%. In patients who did not have all radiographic abnormalities addressed, 33% had a migration index of less than 25% at final follow-up. No intraoperative complications occurred; however, 13 patients had at least 1 postoperative complication. Hip subluxation in skeletally mature patients with cerebral palsy is difficult to treat and is associated with a high incidence of complications. The likelihood of a successful outcome appears to be related to the appropriateness of the surgical procedure. When all radiographic abnormalities were addressed during surgery, a successful radiographic outcome at final follow-up was much more likely than when intervention was less comprehensive.

Abstract
BACKGROUND One-stage hip reconstruction is the gold standard for treatment of hip displacement in children with cerebral palsy. The aims of this study were (1) to report the subjective clinical, objective clinical, and radiographic outcomes; and (2) to investigate outcome predictors, including the influence of the following risk factors: femoral head shape, migration percentage, direction of migration, and age at surgery. METHODS We reviewed 168 hip reconstructions (eighty-two right, eighty-six left) in 121 patients (101 male, twenty female) at a mean follow-up of 7.3 ± 4.6 years (range, four to eighteen years). Surgical outcomes were assessed on the basis of the pain intensity and frequency (measured on 10-point visual analog scales) as well as GMFCS (Gross Motor Function Classification System) and MCPHCS (Melbourne Cerebral Palsy Hip Classification System) scores and postoperative migration percentage. The effects of femoral head shape, preoperative migration percentage, direction of migration, and age at surgery on surgical outcome were assessed by multivariate regression adjusting for potential confounders including sex, triradiate cartilage status, type of cerebral palsy, and surgical technique. RESULTS Pain intensity and frequency were reduced significantly. Preoperative femoral head shape had no significant effect on the changes in pain, MCPHCS grade, and GMFCS level. The preoperative migration percentage was the most influential risk factor with respect to postoperative outcome. Age at surgery had no effect on the changes in pain score and GMFCS level. The overall surgical complication rate was 10.5%. CONCLUSIONS Our data on 168 hip reconstructions at a mean follow-up of seven years showed significant and clinically meaningful improvements in pain intensity and frequency as well as in clinical scores and hip coverage. Analysis of potential risk factors showed only the preoperative migration percentage to have a relevant influence on outcomes.

Abstract
OBJECTIVE To evaluate the association of hip lateralisation with health-related quality of life (HRQL) in children with cerebral palsy (CP) using the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD(®)) questionnaire. METHODS We assessed n = 34 patients (mean age: 10.2 years, SD: 4.7 years; female: n = 16) with bilateral CP and Gross Motor Function Classification System (GMFCS) Level III-V using the CPCHILD(®) questionnaire. Hip lateralisation was measured by Reimer`s migration percentage (MP). RESULTS There was an association between both, MP and GMFCS with CPCHILD(®) total score. Stratified analyses did not suggest interaction of the association between MP and CPCHILD(®) total score by GMFCS level. After adjustment for GMFCS level, we found a significant linear decrease of CPCHILD(®) total score of -0.188 points by 1% increment in MP. CONCLUSIONS There was an association between MP and HRQL, which could not be explained by the GMFCS level.

Abstract
PURPOSE OF REVIEW Spastic type is the most common form of cerebral palsy. The purpose of this review was to evaluate recent literature for current trends in the surveillance and treatment of spastic hip problems in cerebral palsy. RECENT FINDINGS Cerebral palsy is still the most common physical disability in childhood in developed countries. Surveillance programs have had promising results in the detection of 'at risk' patients. However, neither regular radiographic screening nor surgical treatment indications and procedures have shown any progression in the last decade. In addition, recent studies have focused heavily on nonoperative treatment strategies to improve gait. SUMMARY Cerebral palsy is a static encephalopathy causing myostatic contractures especially in the knee and hip. Unbalanced hip contractures can lead to silent hip dislocation. Surgical and rehabilitative approaches such as soft tissue lengthening and proximal femoral and pelvic osteotomies can help patients maintain function and comfort. Selective dorsal rhizotomy or Intrathecal Baclofen Pump insertion or, recently, noninvasive techniques such as neurodevelopmental therapy may help patients and caregivers cope with what is still a devastating and inexorably progressive disorder.

Abstract
AIM The aim of this systematic review was to assess the current validity and reliability of radiological methods used to measure proximal hip geometry in children with cerebral palsy. METHOD A search was conducted using relevant keywords and inclusion/exclusion criteria of the MEDLINE, CINALH Plus, Embase, Web of Science, Academic Search Premier, The Cochrane Library, and PsychINFO databases. RESULTS The migration percentage using X-rays showed excellent reliability and concurrent validity with three-dimensional (3D) measurements from computed tomography (CT) scans. The acetabular index, measured using X-rays had good reliability but moderate concurrent validity with 3D CT measurements; 3D CT scan indexes had greater reliability. The measurement of the neck shaft angle using X-rays showed excellent concurrent validity with measurements from 3D CT scans and excellent reliability. Regarding femoral anteversion, one study found an excellent correlation between two-dimensional CT and clinical assessment and excellent reliability. Two others showed less evidence for the use of CT ultrasounds. INTERPRETATION Most of the X-ray-based measurements showed good to excellent metrological properties. More metrological evidence is needed for the assessment of femoral anteversion. Magnetic resonance imaging and ultrasound-based measurements have great potential although very little metrological evidence is available.
