Project description:BackgroundAt birth, no difference exists between the hips of children with spastic cerebral palsy and the hips of other children. The typical pathologic deformities of the hips in children with spastic cerebral palsy develop as the child gets older. One of our goals was to evaluate the change in quality of life of children with cerebral palsy after hip reconstruction. For classification of the children's condition, we assessed sitting and standing abilities and used the Gross Motor Function Classification System. To evaluate the effect of hip dislocation on the spine, we assessed symmetry while the patient was lying down, sitting, and standing.MethodsThe results of surgical reconstruction of hip joints in 54 patients with severe cerebral palsy who had 66 severely subluxated or dislocated hip joints were retrospectively analyzed. The study was based on a research questionnaire with a mean follow-up of 4 years 10 months. The purpose of the questionnaire was to evaluate the pain, functional abilities, symmetry, and independence of the patients by using the modified Barthel index.ResultsPain was fully relieved in 62 and was eased in 35% of preoperatively painful hips. The functional abilities of sitting and standing were not influenced statistically significantly by the operation. An improvement in sitting symmetry was observed in 40% and improvement in lying symmetry was observed in 32% of the patients. The mean center-edge angle improved from -24.9 degrees +/- 39 degrees (mean +/- standard deviation) to 25.9 degrees +/- 14 degrees . The acetabular index improved from 30.2 degrees +/- 8 degrees to 17.1 degrees +/- 7 degrees .ConclusionsThe independence of the patients, based on the modified Barthel index, did not change significantly after surgery. Most improvements in quality of life were observed in those patients who had pain in the hip before the operation as a result of reduction of pain and improved mobility of the hip.

Project description:PurposeThe acetabulum interacts with the femoral head in daily activities and may exhibit structural changes in the presence of hip disorders. This study aims to redefine hip disorders in children with cerebral palsy by structural characteristics of the acetabulum in relation to the degree of the migration percentage.MethodsThe clinical and radiographic data of 70 patients (36 males, 34 females; mean age 8.2 years) with spastic cerebral palsy were retrospectively analyzed. The acetabular structure was measured by the acetabular index on reconstructed three-dimensional computerized tomography for precision of measurement. Any significant change in acetabular index measured on the reconstructive computerized tomography related to every 10% increment of migration percentage was regarded as clinically significant in hip disorders.ResultsThe acetabular index measured on the reconstructive computerized tomography showed an increasing trend with the increment of migration percentage. The most significant acetabular index measured on the reconstructive computerized tomography change occurred between the 20%-29% and 30%-39% migration percentage groups (p < 0.001), suggesting that a migration percentage of 30% is the starting point of hip disorder. A significant increase in the posterolateral acetabular index measured on the reconstructive computerized tomography occurred in migration percentages >50%, indicating posterolateral acetabular dysplasia. Hips with migration percentages from 80% to 100% had consistent acetabular indexes measured on the reconstructive computerized tomography values, suggesting complete dislocation and no more contact and interaction between the femoral head and acetabular fossa.ConclusionStructural characteristics in the acetabulum reflect hip dysfunction and potentially classify hip disorders. Results suggest the migration percentage 30% as a starting point of hip disorder and 80% as a turning point of hip dislocation in children with cerebral palsy.Level of evidencelevel IV, diagnostic study.

Project description:PurposeProximal femoral excision is a salvage procedure for painful chronic hip dislocation in cerebral palsy (CP) patients. The primary objective of this article is to describe our experience of an amplified interposition myoplasty, with appropriate peri-operative pain and tone management strategies, in a cohort of non-ambulatory CP patients with painful chronic hip dislocation. Our secondary objective is to present the clinical outcomes of these patients.MethodsWe describe our experience in 20 CP patients (25 procedures) at mean 54-month (range 27-169) follow-up with a surgical technique that includes an augmented interposition myoplasty and tone management. The indications for surgery were pain (21 hips), poor sitting tolerance (11) and difficulty with perineal care (8).ResultsThe mean age was 22 years (range 10-40) with 11 patients Gross Motor Function Classification Scale (GMFCS) IV and 9 patients GMFCS V. Mean length of stay was 13 days (3-35). One procedure required revision at 12 months. Mean pain score improved from 7.8 (5-10) pre-operatively to 2.8 (1-5) post-operatively (p < 0.001). Sitting tolerance improved in all patients and in 75 % (15) perineal care was easier.ConclusionsOur interposition myoplasty technique with individualised pain/tone management has good outcomes in this cohort of patients with multiple co-morbidities.

Project description:Hip dislocation in cerebral palsy can lead to pain, pressure sores and difficulty with perineal hygiene. Hip surveillance programs have been implemented to identify patients who might benefit from early intervention and preventive strategies. Surgical techniques used to treat hip dislocation include soft tissue procedures, guided growth, osteotomies and salvage procedures. A search was conducted using Clarivate Web of Science Core Collection on 18 October 2022, to identify all studies of bony or soft tissue surgery for hip pathology in children with cerebral palsy. Fifty-nine original studies and reviews with at least 20 citations were included in this bibliometric analysis. We found that there has been an increase in studies over the decades, with the most studies being published in the Journal of Pediatric Orthopaedics. The United States of America was the most productive country, with Boston Children's Hospital and Harvard University publishing the most articles. The Methodological Index for Non-randomized Studies (MINORS) scoring system was used to analyse the methodological quality of included cohort studies, with the median score being 11 out of 18; many studies had no prospective calculation of study size and lacked control groups. Overall, the literature on this topic appears to be preferentially published in the Journal of Pediatric Orthopaedics, and influential papers by Hagglund 2005 and 2014 continue to be highly cited.

Project description:BackgroundHip displacement (HD) and dislocation in severe Cerebral Palsy (CP) (GMFCS III, IV, V) are important causes of worsening disability and quality of life. Prevention must be started from the first months of life through screening programs and early treatments, both conservative and surgical. Evidence from Clinical Practice Guidelines also suggests the development of Care Pathways for good clinical practice. At the beginning of 2020 an interdisciplinary, multi-professional working group, composed of 26 members (including Physiatrists, Physiotherapist, Neuro-psychomotor Therapists and Orthopedists representing the respective Italian Scientific Societies) with the involvement of the FightTheStroke Foundation families' association, was set up.AimThe aim of the multi-professional panel was the production of evidence-based recommendations for the Care Pathway "Prevention of Hip Displacement in children and adolescents with severe CP" for best clinical practice implementation in our national context.DesignClinical Care Pathway (Clinical Practice Guideline).SettingInpatient and outpatient.PopulationChildren with severe CP (GMFCS III-IV-V).MethodsThe recommendations of this Care Pathway were developed using the American Academy for Cerebral Palsy and Developmental Medicine (AACPDM) guidelines for Care Pathways development and the Grading of Recommendations Assessment Development and Evaluation (GRADE ADOLOPMENT) working group for adoption or adaption or de novo development of recommendations from high-quality guidelines. In 2020 a multidisciplinary working group (WG) developed four research questions on the prevention of HD on the following topics: screening, botulinum toxin treatment, postural management and preventive soft tissue surgery. A comprehensive review of the biomedical literature was performed on each question. Guidelines, Systematic Reviews and Primary studies were retrieved through a top-down approach. References were screened according to inclusion criteria and quality was assessed by means of specific tools. A list of recommendations was then produced divided by intervention (screening programs, postural management, botulinum toxin, preventive surgery). In a series of meetings, the panel graduated recommendations using the GRADE evidence to decision frameworks.ResultsFifteen recommendations were developed: seven on screening programs, four on postural management strategies, one on botulinum toxin, and three on preventive surgery. Evidence quality was variable (from very low to moderate) and only a few strong recommendations were made.ConclusionsIn severe CP at high risk of hip dislocation, it is strongly recommended to start early hip surveillance programs. In our national context, there is a need to implement Screening programs and dedicated Network teams. We also strongly recommend a comprehensive approach shared with the families and goal-oriented by integrating the different therapeutic interventions, both conservative and not, within Screening programs.Clinical rehabilitation impactImplementing a comprehensive multi-professional approach for the prevention of hip dislocation in severe CP.

Project description:Developmental dysplasia of the hip (DDH) in cerebral palsy (CP) is very rare, and very little clinical data is available. We have analysed the results of open reduction of the hip (Howorth), acetabuloplasty (Salter, Pemberton), pelvic osteotomy (Chiari) and femoral osteotomy in the treatment of the DDH in CP patients. Radiographic assessment was based on the Severin grading classification system and measurements of migration percentage (MP) before and after surgery. Clinical results were analysed using the Ponsetti classification system in ambulatory patients. A total of 45 hips in 31 patients were treated surgically. The average age of the patients was 5.2 years (range: 2-16 years). The average follow-up was 9.6 years (range: 3-28 years). Analysis of the radiographic results according to Severin placed 35 hips (77.8%) in groups 1 and 2 and ten hips (22.2%) in groups 3 and higher. The average preoperative MP value was 78.7% and the average postoperative MP was 15.2%. Redislocation occurred in three hips. Clinical results were disappointing: based on Ponsetti assessment 14 hips (36.8%) were classified in the first three groups and 24 hips (63.2%) in the last three groups. This analysis suggests that these surgical procedures could be applied in treating DDH in CP.

Project description: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.

Project description:AimTo investigate the prevalence, characteristics, and risk factors of hip pain in adolescents with cerebral palsy (CP) and compare the findings with those of the same individuals 5 years earlier.MethodSixty-seven adolescents (28 females, 39 males; mean age 14y 7mo; SD 1y 5mo; range 12-17y) with bilateral CP, in Gross Motor Function Classification System (GMFCS) levels III to V enrolled in a CP surveillance programme were assessed for hip pain. Their caregivers responded to the questions on the intensity and frequency of hip pain from the Child Health Questionnaire (CHQ) (transformed to CHQ hip pain score; 100 indicates no pain). Interference of hip pain with daily activities and sleep was recorded on numeric rating scales. Hip displacement was measured radiographically by the migration percentage.ResultsTwenty-eight participants had 44 painful hips. Their mean CHQ hip pain score was 40 (SD 21.4; range 10-80). Independent risk factors for hip pain, low CHQ hip pain score, and interference with sleep were severe hip subluxation (migration percentage 50-89%) and GMFCS level V. A migration percentage of 50% to 89% was the only independent risk factor for interference with daily activities. Over 5 years, the number of participants with hip pain increased from 18 to 28, while the mean migration percentage of the most displaced hip was unchanged.InterpretationOur CP hip surveillance programme did not protect the participants against increasing prevalence of hip pain during adolescence. We suggest that surveillance programmes for CP should include guidelines on the characteristics and management of hip pain.What this paper addsHip pain prevalence increased in adolescents over a 5-year period in a cerebral palsy surveillance programme. Risk factors for hip pain were Gross Motor Function Classification System level V and severe hip subluxation.

Project description:ImportanceThere is no consensus on interventions to slow the progress of hip displacement in patients with cerebral palsy.ObjectiveTo investigate the efficacy of a novel hip brace in preventing progressive hip displacement in patients with cerebral palsy.Design, setting, and participantsThis 2-group randomized clinical trial was conducted at 4 tertiary hospitals in South Korea from July 2019 to November 2021. Participants included children aged 1 to 10 years with nonambulatory cerebral palsy (Gross Motor Function Classification System level IV or V). Block randomization was used to assign an equal number of patients to the study and control groups via computerized random allocation sequences. Data were analyzed from November to December 2021.InterventionsThe intervention group wore the hip brace for at least 12 hours a day for the study duration (ie, 12 months). Follow-up evaluations were performed after 6 and 12 months of wearing the brace. Both groups proceeded with conventional rehabilitation therapy during the trial.Main outcomes and measuresThe primary outcome was the Reimers migration index (MI) on radiography, as assessed by 3 blinded investigators. Primary outcome variables were analyzed using linear mixed models. Secondary outcomes include change in the Caregiver Priorities & Child Health Index of Life with Disabilities, on which lower scores indicate better quality of life.ResultsA total of 66 patients were included, with 33 patients (mean [SD] age, 68.7 [31.6] months; 25 [75.8%] boys) randomized to the intervention group and 33 patients (mean [SD] age, 60.7 [24.9] months; 20 [60.6%] boys) randomized to the control group. The baseline mean (SD) MI was 37.4% (19.3%) in the intervention group and 30.6% (16.3%) in the control group. The mean difference of the MI between the intervention group and control group was -8.7 (95% CI, -10.2 to -7.1) percentage points at 6 months and -12.7 (95% CI, -14.7 to -10.7) percentage points at 12 months. The changes in the Caregiver Priorities & Child Health Index of Life with Disabilities were favorable in the study group and reached statistical significance at the 6-month follow-up compared with the control group (difference, -14.2; 95% CI, -25.2 to -3.3).Conclusions and relevanceIn this randomized clinical trial, the novel hip brace was significantly effective in preventing the progression of hip displacement, compared with the control group. It effectively improved quality of life in patients with nonambulatory cerebral palsy. Therefore, hip brace use could be a promising treatment method to delay hip surgery and improve the quality of life of patients with nonambulatory cerebral palsy.Trial registrationClinicalTrials.gov Identifier: NCT04033289.

Project description:BackgroundThis large, retrospective, single-center study aimed to compare the outcomes of unilateral hip reconstruction and bilateral hip reconstruction in children with non-ambulatory cerebral palsy and ascertain risk factors for recurrent instability and reoperation.MethodWe performed a retrospective review of 137 hip reconstructions performed for patients with cerebral palsy. Preoperative and postoperative clinical and radiological parameters were documented, including hip migration percentage, acetabular index, the Gross Motor Function Classification System, the Melbourne Cerebral Palsy Hip Classification System, hip abduction, and pelvic obliquity.ResultsOverall, 49 patients underwent bilateral hip reconstruction, and 37 patients underwent unilateral hip reconstruction. In the unilateral hip reconstruction group, the reconstructed hip remained stable (with a migration percentage < 33%) in 59% of patients compared to 74.4% of the more affected hips in the bilateral hip reconstruction group (p = 0.02). Of the unreconstructed hip in the unilateral hip reconstruction group, 74.4% remained stable (with a migration percentage < 33%), compared to 78.8% of the less affected hips in the bilateral hip reconstruction group. A level pelvis was maintained at final follow-up in significantly more patients in the bilateral hip reconstruction group than the unilateral hip reconstruction group (p = 0.002). Further surgical intervention was performed in 41% of the unilateral hip reconstruction group, compared with 11.5% in the bilateral hip reconstruction group (p = 0.001). Surgery performed under the age of 8 years and not performing an acetabular osteotomy were found to be risk factors for recurrent instability in all groups.ConclusionOur series suggests that in terms of recurrent instability after hip reconstruction in cerebral palsy, protective factors against this complication include bilateral hip reconstruction, hip reconstruction after 8 years of age, and the use of an acetabular osteotomy.
