Abstract
BACKGROUND Congenital synostosis of the knee is a rare condition with limited data on treatment options and outcomes. This study reports clinical findings, treatment approach, and surgical/clinical outcomes for congenital synostosis of the knee. METHODS An institutional review board-approved retrospective review of patients with congenital synostosis of the knee presenting to 2 institutions between 1997 and 2021 was performed. RESULTS Eight patients (13 knees) with a median follow-up of 11.3 years (3.3 to 17 y) were included. Seven patients had associated syndromes. Patients presented with an average knee flexion deformity of 100° (range 60 to 130°) and delayed walking ability. Seven patients had associated upper extremity hypoplasia/phocomelia. The average age at the index surgery was 4.3 years (range 1.2 to 9.2 y). Synostosis resection with gradual deformity correction was performed in most patients. An attempt was made at a mobile knee in some patients, but all went on to knee fusion. Mean flexion deformity at final follow-up was 11.6° (range: 0 to 40°) and 5 limbs were fused in full extension. Mean limb length discrepancy at final follow-up was 6.8 cm (range: 0 to 8 cm). All patients maintained their improved ambulation status at final follow-up. Twenty-two complications were identified. CONCLUSIONS Reliable correction of the deformity associated with congenital knee synostosis was achieved at a median follow-up of 11 years. Importantly, all patients maintained their improved ambulation at final follow-up. This is the largest study on patients with congenital knee synostosis and outlines a reconstructive approach to improve ambulatory status. LEVEL OF EVIDENCE Level IV.

Ponseti treated idiopathic clubfoot - outcome predictive factors in the test of time: analysis of 500 feet followed for five to 20 years. J Child Orthop 2021; 15:426-432. [PMID: 34858528 PMCID: PMC8582614 DOI: 10.1302/1863-2548.15.210156] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Accepted: 09/07/2021] [Indexed: 02/03/2023] Open
Abstract
PURPOSE To investigate a set of risk factors on the outcome of Ponseti treated idiopathic clubfeet (ICF). METHODS This study was approved by the institutional review board. A retrospective analysis of prospectively gathered data over a 20-year period, at a single dedicated clubfoot clinic. Records of 333 consecutive infants with 500 ICF were analyzed. Initial Pirani score, number of casts, need for tenotomy, foot abduction brace compliance and functional score had been documented. The need for surgery after initial correction was the outcome measure. All children were followed by the same team throughout the study period. Descriptive statistics, chi-squared and multivariate analysis were performed. RESULTS In total, 82 children (24%) with 119 feet (23.8%) were operated on, with 95.1% of feet being operated up to the age of nine years. There was a significant correlation between the Pirani score at presentation and the number of surgical procedures (chi-squared = 79.32; p < 0.001). Achilles tenotomy was done in 94.8% of patients. Pirani score of > 4.5 before casting was strongly associated with increased surgical risk (odds ratio = 1.95). When six to eight cast changes were needed, surgical prospect was 2.9 more, increasing to 11.9 when nine or more casts were needed. CONCLUSION Foot severity and number of cast changes were the strongest predictors for future surgery. Estimation of the risk of deformity recurrence after initial correction may help in tailoring a cost-effective personal treatment and follow-up protocol. Personalized focused protocol will help patients and caregivers and will reduce expenses. LEVEL OF EVIDENCE Level II - prognostic study.

Abstract
PURPOSE The aim of this study was to evaluate the success of guided growth by temporal hemiepiphysiodesis of the lateral proximal tibia as a first line treatment option for Blount disease. METHODS This was a retrospective multicentre study conducted in five centres, covering data on 55 limbs in 45 patients, with an average follow-up of 24.5 months following plate insertion. Preoperative alignment analysis was compared with three measurements taken postoperatively. The normalization of the mechanical medial proximal tibia angle (mMPTA) was defined as the primary outcome measure. RESULTS Mean age at surgery was 9.5 years. Average preoperative mMPTA was 77°. On average, at 24.5 months post-surgery, mMPTA was 86.33°, while 43/55 limbs (78.18%) have achieved normalization (mMPTA 85° to 90°). Average rate of correction was 1° per month. When grouping the children as infantile (11 limbs), juvenile (12 limbs) and adolescent (32 limbs), operated on before the age of four years, between four and ten years and after the age of ten years, respectively, 63.63%, 66.67%, 87.5% have completed correction of deformity during the follow-up period. Interestingly, the femoral component of the deformity has achieved correction as well in 33/55 limbs (64%). CONCLUSION Hemiepiphysiodesis is an effective first line treatment for Blount disease. Overall success rate is good but varies according to child's age. Adolescent Blount has the best chance of achieving full correction while same treatment is less effective in infantile Blount.Level of evidence: IV.

Abstract
AIMS To analyze outcomes reported in studies of Ponseti correction of idiopathic clubfoot. METHODS A systematic review of the literature was performed to identify a list of outcomes and outcome tools reported in the literature. A total of 865 studies were screened following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and 124 trials were included in the analysis. Data extraction was completed by two researchers for each trial. Each outcome tool was assigned to one of the five core areas defined by the Outcome Measures Recommended for use in Randomized Clinical Trials (OMERACT). Bias assessment was not deemed necessary for the purpose of this paper. RESULTS In total, 20 isolated outcomes and 16 outcome tools were identified representing five OMERACT domains. Most outcome tools were appropriately designed for children of walking age but have not been embraced in the literature. The most commonly reported isolated outcomes are subjective and qualitative. The quantitative outcomes most commonly used are ankle range of motion (ROM), foot position in standing, and muscle function. CONCLUSIONS There is a diverse range of outcomes reported in studies of Ponseti correction of clubfoot. Until outcomes can be reported unequivocally and consistently, research in this area will be limited. Completing the process of establishing and validating COS is the much-needed next step.Cite this article: Bone Joint Open 2020;1-8:457-464.

Abstract
PURPOSE The Ponseti method is a well-established approach to treating clubfoot. Potentially, both the underlying pathology and adherence to post-correction bracing can affect lower limb function and age of independent standing and walking. This cohort study investigates the age at which infants with idiopathic clubfoot treated using the Ponseti method achieved three selected developmental milestones and whether or not this correlated with treatment compliance. METHODS A prospectively collected database from four centres was visited. Inclusion criteria were patients with idiopathic clubfoot with no comorbidities or prior treatment. Age at attainment of independent standing, walking, nocturnal continence was compared across three groups: I) congenital talipes equinovarus (CTEV) children compliant with treatment; II) CTEV children non-compliant with treatment; and III) typically-developed siblings. Minimum follow-up was five years. RESULTS In all, 130 patients (198 feet) fitted the inclusion criteria: 43:87 (F:M). Standing was achieved by a mean 12.0 months in group I (sd 2.50); 12.0 months (sd 2.0) in II and ten months (sd 3.0) in III. Walking was achieved by a mean 15 months (sd 4.0) in group I, 14 months (sd 1.75) in II and 12 months (sd 3) in III, respectively. Both the compliant and non-compliant CTEV children were significantly slower at achieving standing and walking compared to sibling controls (p < 0.0001). There was no significant difference between age of nocturnal continence between the three groups. CONCLUSION Infants with idiopathic clubfoot treated according to the Ponseti method achieve independent standing and walking approximately two months later than their typically-developed siblings. The delay is not related to the use of the foot abduction brace. LEVEL OF EVIDENCE III.

Abstract
Aims The Ponseti method is the benchmark treatment for the correction of clubfoot. The primary rate of correction is very high, but outcome further down the treatment pathway is less predictable. Several methods of assessing severity at presentation have been reported. Classification later in the course of treatment is more challenging. This systematic review considers the outcome of the Ponseti method in terms of relapse and determines how clubfoot is assessed at presentation, correction, and relapse. Patients and Methods A prospectively registered systematic review was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies that reported idiopathic clubfoot treated by the Ponseti method between 1 January 2012 and 31 May 2017 were included. The data extracted included demographics, Ponseti methodology, assessment methods, and rates of relapse and surgery. Results A total of 84 studies were included (7335 patients, 10 535 clubfeet). The relapse rate varied between 1.9% and 45%. The rates of relapse and major surgery (1.4% to 53.3%) and minor surgery (0.6% to 48.8%) both increased with follow-up time. There was high variability in the assessment methods used across timepoints; only 57% of the studies defined relapse. Pirani scoring was the method most often used. Conclusion Recurrence and further surgical intervention in idiopathic clubfoot increases with the duration of follow-up. The corrected and the relapsed foot are poorly defined, which contributes to variability in outcome. The results suggest that a consensus for a definition of relapse is needed.

Abstract
PURPOSE To evaluate the temporal and spatial sequence of events following temporal hemiepiphysiodesis in idiopathic knee varus/valgus. METHODS This is a retrospective multicentre study on 372 physes in 206 patients. The average rate of correction (ROC) was calculated; univariate and multivariate analysis were performed. RESULTS In all, 92% of the femoral physes were followed for more than one year/reached skeletal maturity. Of those, 93% were corrected to a mechanical lateral distal femoral angle (mLDFA) of 85° to 89°; 2% did not, while 5% were over-corrected. A total of 92% of the tibial physes were followed for more than one year/reached skeletal maturity. Of those, 92% were corrected to a mechanical medial proximal tibial angle (mMPTA) of 85° to 89°; 2% did not, while 6% were over-corrected. Factors significantly influencing success and ROC were age, direction and magnitude of deformity. Femoral ROC was significantly faster than tibial ROC: 0.85° versus 0.78°/month, respectively (p = 0.05). Femoral valgus ROC was significantly faster than varus ROC: 0.90° versus 0.77°/month, respectively (p = 0.04). A constant was derived to calculate the amount of correction. Significant correlation was found between calculated and actual mLDFA in valgus deformity during the first year (r = 0.58 to 0.87, p < 0.01). Calculated mLDFA of varus deformity did not correlate with actual mLDFA. Significant correlation was found when calculating mMPTA correction in all deformities. CONCLUSIONS Femur corrects faster than tibia; valgus femoral deformities are corrected faster than varus. Valgus correction in the distal femur/proximal tibia as well as varus correction in the tibia in idiopathic patients is highly predictable. The constant derived is the first tool which enables predicting and monitoring amount of correction in hemiepiphysiodesis when correcting angular deformities around the knee. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE To point out the need to take into account the dysplastic nature of tarsal bones when treating idiopathic clubfoot (CF). METHODS Review the published evidence on the developmental abnormalities of tarsal bones in idiopathic CF. RESULTS The literature review provides abundant proof of the existence of delayed appearance and slower development of ossification centres of tarsal bones in idiopathic clubfoot. CONCLUSION Gentle manipulations and casting are the cornerstone of the Ponseti method. The biological response of all foot elements is critical for a successful outcome. Delayed ossification and abnormal development of tarsal bones in idiopathic CF may affect the results. Development of a personalized tailored bracing protocol based on severity assessment and response to casting treatment will improve results and quality of care in CF management. LEVEL OF EVIDENCE V.

Abstract
OBJECTIVES We sought to evaluate foot length (FL) and forefoot circumference (FC) and their impact on the severity of idiopathic clubfoot (CF) and results of treatment. We hypothesized that a smaller foot size at birth that represents a lesser than term newborn may affect the response of the CF to the treatment. METHODS We conducted a prospective study documenting FL and FC of all neonates presented with idiopathic CF. Additional demographic information was collected. Outcome measures were number of casts needed for correction, need for recasting, additional surgery and functional score. RESULTS In all, 52 children with 73 CF with a minimum mean follow-up of two years (2.0 to 5.6; sd 1.08) were evaluated. Mean gestational age was 38.63 weeks and mean birth weight (BW) was 3184 g. The mean FL at presentation was 74 mm (5.70 to 9.00), initial Pirani score was 5.5 (2.5 to 6.0) while number of casts was 6.9 (4.0 to 11.0). The FL was significantly correlated both to initial Pirani score (r = -0.35; p < 0.01) and number of casts (r = -0.33; p < 0.05). Positive correlation was found between the number of casts to Pirani score and number of additional procedures (r = 0.39; r = 0.36; p < 0.01, respectively). A foot size of up to 8 cm, needed 7.3 casts (4 to 7) compared with a FL of 8 cm or longer who needed 4.7 casts (4 to 6; t = 7.11; p < 0.001). CONCLUSION FL is a simple approach to identify preterm babies. It can be used as part of the initial evaluation of CF and help in predicting the course of treatment. We recommend adding FL to the existing classification. LEVEL OF EVIDENCE I - Prognostic study.

Abstract
Spondylometaphyseal dysplasia (SMD) is characterized by developmental changes in long bones and vertebrae. It has large phenotypic diversity and multiple genetic causes, including a recent link to novel variants in the extracellular matrix (ECM) protein fibronectin (FN), a regulator of ECM assembly and key link between the ECM and proper cell function. We identified a patient with a unique SMD, similar to SMD with corner fractures. The patient has been followed over 19 years and presents with short stature, genu varum, kyphoscoliosis, and pectus carinatum. Radiography shows metaphyseal changes that resolved over time, vertebral changes, and capitular avascular necrosis. Whole exome sequencing identified a novel heterozygous FN1 variant (p.Cys97Trp). Using mass spectroscopy, mutant FN was detected in plasma and in culture medium of primary dermal fibroblasts isolated from the patient, but mutant protein was much less abundant than wild-type FN. Immunofluorescence and immunoblotting analyses show that mutant fibroblasts assemble significantly lower amounts of FN matrix than wild-type cells, and mutant FN was preferentially retained within the endoplasmic reticulum. This work highlights the importance of FN in skeletal development, and its potential role in the pathogenesis of a subtype of SMD.

Abstract
PURPOSE Distinct normal physiological patterns of fat conversion in vertebrae were described both for children and adults. Our aim was to evaluate the T1-weighted bone marrow pattern of the vertebral bodies in various sites along the scoliotic spine of children with adolescent idiopathic scoliosis (AIS). METHODS We retrospectively evaluated spine MRI studies of children with AIS. Scoliosis radiographs were assessed for type of curvature according to the Lenke classification. A paediatric neuroradiologist assessed the T1-weighted signal of vertebral bodies in comparison with the adjacent disc and distinct patterns of fatty conversion within the apical and stable vertebral bodies. Statistical assessment was performed. RESULTS MRI study of the spines of 75 children with AIS were assessed, 59 (79%) of whom were female, with an age range of nine to 19 years. The relative overall T1-weighted signal intensity of the vertebral body bone marrow relative to the intervertebral disc was hyperintense in 76% and isointense in 24%. Fatty conversion grade of the stable vertebra was higher than the apex vertebra (p = 0.0001). A significant tendency to have more advanced fat conversion patterns in the apex vertebra up to age 13.5 years old compared with adolescents above that (p = 0.015) was seen. CONCLUSION This preliminary study suggests a different pattern of bone marrow conversion in AIS from the normal physiologic pattern described in the literature. Whether these changes are secondary to the biomechanics of the curved spine or may suggest that bone marrow maturation rate and content have a role in the pathogenesis of AIS remains to be further researched.

Abstract
BACKGROUND Guided growth by tension band plating is commonly used to correct coronal plane deformity. The purpose of this study was to measure the effect and further define parameters that influence results in coronal plane deformity around the knee. METHODS The retrospective multicentre study included data on 967 physes in 537 patients, with an average follow-up of 16 months after plate insertion. Alignment analysis was compared preoperatively and in at least two measurements postoperatively, as well as with parameters that influence the rate and amount of correction. RESULTS Average age at plate implantation was 11.35 years (SD 3.29).Of those with femoral deformities, 85% of the patients finished the treatment and of those, 70% were corrected to standard alignment, while 14% have not yet achieved correction, and are still growing.Of those with tibial deformities, 75% of the patients finished the treatment and of those 80% were corrected to standard alignment, while 25% have not yet achieved correction and are still growing.The calculated rate of correction was 0.77°/month for the femur and 0.79°/month for the tibia.In terms of complications, the overall rate of infection was 1.48%. In three patients (0.55%) screw breakage was recorded.Factors found to significantly influence the amount of correction were age at plate implantation and direction of deformity. CONCLUSION Temporary hemiepiphysiodesis takes the advantage of physiological physeal growth to effectively treat angular deformities. Success of treatment is influenced by the age of the patient at plate implantation and direction of deformity. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND Evaluation of the results of treatment for clubfoot by the Ponseti technique is based on clinical and functional parameters. There is a need to establish universally recognized quantitative measurements to compare, better understand, and more precisely evaluate therapeutic outcome. METHODS Nine angles were measured on standard radiographs of 145 children with idiopathic clubfeet treated between 2000 and 2010 with the Ponseti method. The average follow-up was 6.3 years. The need for additional surgery and the functional outcome was correlated to the radiologic measurements. RESULTS Three radiologic parameters were identified as having significant (P ≤ .001) predictive value. The lateral tibiocalcaneal angle with the ankle at maximal dorsiflexion measuring fixed equinus was larger in the preoperated group (77 ± 12 degrees) compared to the nonoperated group (67 ± 14 degrees). Functional outcome was better with smaller angles. The lateral talocalcaneal angle with the ankle at maximal dorsiflexion measuring hindfoot rigidity was smaller (29 ± 8 degrees) in the preoperated group compared to the nonoperated group (35 ± 9 degrees). Functional outcome was better with larger angles. The lateral talo-first metatarsal angle with the ankle at maximal plantarflexion measuring foot cavus was larger in the preoperated group (31 ± 10 degrees) compared to the nonoperated group (22 ± 11 degrees), whereas functional outcome did not correlate with this angle. CONCLUSIONS The lateral view with the foot in maximal dorsiflexion was found to be the most significant and useful view to detect abnormality in Ponseti-treated clubfeet. In our practice now, we are using only this view in order to reduce the radiation exposure to the child. LEVEL OF EVIDENCE Level III, retrospective case series.

Abstract
BACKGROUND Polyostotic fibrous dysplasia is a skeletal disease that results from somatic activating mutations in the gene GNAS in skeletal stem cells, leading to proliferation of immature osteogenic cells with replacement of normal marrow and bone with fibro-osseous tissue. Lesions may cause bone deformity or fracture. In the surgical care of polyostotic fibrous dysplasia, the role of grafting and the optimal grafting material are not clear. The purpose of this study was to evaluate the long-term survival of bone-grafting procedures in subjects with polyostotic fibrous dysplasia over time. METHODS The operative reports and radiographs of a cohort of subjects with polyostotic fibrous dysplasia followed in a natural history study were reviewed. Twenty-three subjects (mean age at the time of enrollment, thirteen years [range, two to forty years]) with fifty-two bone-grafting procedures had a mean follow-up time of 19.6 years (range, twenty-nine months to forty-seven years). Kaplan-Meier life table estimates, Cox proportional hazard models, and t tests comparing means were performed to assess various aspects of graft survival. RESULTS Kaplan-Meier curves showed a 50% estimate of survival of 14.5 years. Cox proportional hazards models showed no advantage comparing allograft with autograft or structural with nonstructural graft materials. The mean age of the patients was significantly greater (p < 0.001) in the subgroup of subjects in whom grafts were maintained over time (20.9 years) compared with the subgroup of patients whose grafts were resorbed over time (9.8 years). CONCLUSIONS Bone-grafting, including both allograft and autograft, is of limited value in ablating the lesions of fibrous dysplasia. The expectations of patients and surgeons should include the high probability of graft resorption over time with return of bone characteristics of fibrous dysplasia, particularly in younger patients. This suggests the maintenance of normal bone mechanics with implant support should be the priority of any surgical intervention.

Abstract
We retrospectively assessed the effect of ankle-foot orthosis (AFO) on the foot progression angle (FPA) of 97 children with spastic cerebral palsy (CP) who had undergone comprehensive computer-based gait analysis both barefoot and with their orthosis, during the same session. The physical examination results and the gait study temporal and kinematic parameters comprise the study data. We focused on the peak FPA reached during stance and swing phases and at mid-stance and mid-swing, and also measured the transverse rotations of the pelvis, the femur and the tibia. AFOs improved gait, as reflected by improved temporal parameters, but they also increased internal rotation of the feet in diplegic CP children by 4.29 degrees for mid-stance, and by 3.72 degrees for mid-swing. The correlation between components of the rotational profile and FPA was significant for the diplegic group. AFOs did not produce any noteworthy differences between walking barefoot and walking with the brace in the hemiplegic group in what concerns FPA. Children with diplegic CP who use AFOs walk with increased internal FPAs in their orthoses. These findings might be explained by anatomical attributes as well as dynamic features during gait.

Abstract
PURPOSE There is conflicting evidence related to factors affecting the rates of recurrence of idiopathic club feet using the Ponseti method. We attempt to evaluate the predictors of success and failure in our physiotherapy-led Ponseti club foot clinic. METHODS We evaluated 189 children with 279 club feet with a mean follow-up of 6.3 years for the following: Pirani score at presentation, number of casts for correction, indication for Achilles tenotomy, and the duration of foot abduction brace (FAB) use, in relation to outcome. Outcome measures were the need for additional surgery and functional scores. Based on the pattern and rate of ossification of the tarsal bones in idiopathic club foot, a much longer FAB weaning protocol was designed and practiced since 2000. The objective of this study was to answer the question of whether a prolonged period of FAB use reduces the need for surgery in Ponseti-treated idiopathic club foot. RESULTS Thirty-six feet (12.9 %) underwent additional surgery. The Pirani score and the number of cast changes had no influence on the rate of surgery. The duration of FAB use had a significant effect on the outcome, i.e., the rate of surgery and functional scoring. Operated children used the FAB for 28 months versus 33 months in the non-operated group (p < 0.05). Only a minor delay in the attainment of walking age was noted (average 15 months). CONCLUSIONS The duration of FAB treatment was found to be the most influential on the functional results and on rate of surgery. Close follow-up and longer FAB weaning program reduced the rates of recurrence.

A functional electrical stimulation system improves knee control in crouch gait. J Child Orthop 2015; 9:137-43. [PMID: 25786388 PMCID: PMC4417739 DOI: 10.1007/s11832-015-0651-2] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Accepted: 03/10/2015] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Crouch gait is a major sagittal plane deviation in children diagnosed with cerebral palsy (CP). It is defined as a combination of excessive ankle dorsiflexion and knee and hip flexion throughout the stance phase. To the best of our knowledge, functional electrical stimulation (FES) has not been used to decrease the severity of crouch gait in CP subjects and assist in achieving lower limb extension. PURPOSE To evaluate the short- and long-term effects of FES to the quadriceps muscles in preventing crouch gait and achieving ankle plantar flexion, knee and hip extension at the stance phase. METHODS An 18-year-old boy diagnosed with CP diplegia [Gross Motor Function Classification System (GMFCS) level II] was evaluated. The NESS L300(®) Plus neuroprosthesis system provided electrical stimulation of the quadriceps muscle. A three-dimensional gait analysis was performed using an eight-camera system measuring gait kinematics and spatiotemporal parameters while the subject walked shod only, with ground reaction ankle foot orthotics (GRAFOs) and using an FES device. RESULTS Walking with the FES device showed an increase in the patient's knee extension at midstance and increased knee maximal extension at the stance phase. In addition, the patient was able to ascend and descend stairs with a "step-through" pattern immediately after adjusting the FES device. CONCLUSIONS This report suggests that FES to the quadriceps muscles may affect knee extension at stance and decrease crouch gait, depending on the adequate passive range of motion of the hip, knee extension, and plantar flexion. Further studies are needed in order to validate these results.

Abstract
CONTEXT Fibrous dysplasia (FD) is a rare skeletal disorder, resulting in deformity, fracture, functional impairment, and pain. Bisphosphonates have been advocated as a potential treatment. OBJECTIVE To determine the efficacy of alendronate for treatment of FD. DESIGN Two-year randomized, double-blind, placebo-controlled trial. SETTING Clinical research center. PATIENTS Forty subjects with polyostotic FD (24 adults, 16 children). Subjects were randomized and stratified by age. INTERVENTIONS Study drug was administered over a 24 month period in 6 month cycles (6 months on, 6 months off). Alendronate dosing was stratified: 40 mg daily for subjects >50 kg, 20 mg for 30-50 kg, 10 mg for 20-30 kg. MAIN OUTCOME MEASURES Primary endpoints were bone turnover markers, including serum osteocalcin, and urinary NTX-telopeptides. Secondary endpoints included areal bone mineral density (aBMD), pain, skeletal disease burden score, and functional parameters including the 9-min walk test and manual muscle testing. RESULTS Clinical data was collected on 35 subjects who completed the study. There was a decline in NTX-telopeptides in the alendronate group (P = .006), but no significant difference in osteocalcin between groups. The alendronate group had an increase in areal BMD in normal bone at the lumbar spine (P = .006), and in predetermined regions of FD (P < .001). There were no significant differences in pain scores, skeletal disease burden scores, or functional parameters between the groups. CONCLUSIONS Alendronate treatment led to a reduction in the bone resorption marker NTX-telopeptides, and improvement in aBMD, but no significant effect on serum osteocalcin, pain, or functional parameters.

The efficacy of neuroprosthesis in young hemiplegic patients, measured by three different gait indices: early results. J Child Orthop 2013; 7:537-42. [PMID: 24432118 PMCID: PMC3886350 DOI: 10.1007/s11832-013-0540-5] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2013] [Accepted: 10/08/2013] [Indexed: 02/03/2023] Open
Abstract
PURPOSE To evaluate functional electrical stimulation (FES) neuroprothesis as a method to improve gait in hemiplegic patients, using three different gait scoring methods as measures. METHODS Five hemiplegic patients (four with cerebral palsy at GMFCS I, one with diffuse pontine glioma) with a mean age of 16.5 years were given a FES neuroprosthesis (NESS(®) L300™) that was applied and calibrated individually. After an adaptation period during which the participants increased their daily use of the neuroprosthesis, gait was assessed with the stimulation off and with the FES on. Kinematic, kinetic, and temporal spatial data were determined using motion analysis and summarized by three scoring methods: Gait Profile Score (GPS), Gait Deviation Index (GDI), and Gillette Gait Index (GGI). Indices were calculated using the Gaitabase program available online. Patients were followed for a minimum of 1 year. RESULTS When comparing gait with and without stimulation, all scoring methods showed improvement. GPS and GDI of the affected leg were significantly improved: 12.23-10.23° (p = 0.017) and 72.36-78.08 (p = 0.002), respectively. By applying the movement analysis profile, the decomposed GPS score, we found that only the ankle dorsiflexion and the foot progression angle were significantly changed. GGI of the affected leg showed improvement, but without statistical significance: 168.88-131.64 (p = 0.221). Total GPS of legs and the GPS, GDI, and GGI of the nonaffected leg showed improvement without statistical significance. At the 1-year follow-up, all patients expressed high satisfaction and continued to use the device. CONCLUSIONS Dorsiflexion functional electrical stimulation improves gait in hemiplegic patients, as reflected by GPS, GDI, and GGI.

Factors associated with the success of the Rigo System Chêneau brace in treating mild to moderate adolescent idiopathic scoliosis. J Child Orthop 2012; 6:327-31. [PMID: 23904900 PMCID: PMC3425705 DOI: 10.1007/s11832-012-0429-8] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2012] [Accepted: 07/21/2012] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Adolescent idiopathic scoliosis (AIS) is the most prevalent spine deformity within the pediatric population. Orthosis is the mainstay of conservative treatment for mild to moderate AIS. The Rigo System Chêneau (RSC) brace is a custom-made thoracolumbar sacral orthosis (TLSO) based on a three-dimensional correction concept. The purpose of this study was to identify factors that could predict the therapeutic success/failure of the RSC brace. MATERIALS AND METHODS A retrospective cohort study was performed on all consecutive patients according to the Scoliosis Research Society (SRS) criteria for the success of conservative treatment. Participants had a 2-year follow-up beyond the termination of brace treatment. All patients were treated with the RSC orthotic device. RESULTS Ninety-three patients met the inclusion criteria. At treatment onset, their average age was 12.9 years, average Cobb angle 31.97°, Risser score 1.07, and the mean angle of thoracic rotation (ATR) was 10.2°. The mean brace treatment period was 36 months. Treatment was successful in 83.8 % of these patients (n = 79). The average final Cobb angle was 28.97°, Risser score 4.88, and ATR 8.09°. The pre-treatment factors associated with the success of applying the RSC brace were a high Risser score [odds ratio (OR) = 2.97, 95 % confidence interval [CI] 1.18-7.44; p = 0.02), a low Cobb angle (OR = 0.92, 95 % CI 0.85-0.99; p = 0.02), and low ATR (OR = 0.86, 95 % CI 0.75-0.99; p = 0.04). CONCLUSIONS The treatment of mild to moderate AIS with the RSC brace provides excellent clinical results. Its added benefit is enabling a three-dimensional correction of a three-dimensional deformity. Pre-treatment high Risser score, low Cobb angles, and low ATRs are associated with treatment success. LEVEL OF EVIDENCE Retrospective analysis, Level III.

Abstract
Background Second opinion is a treatment ratification tool that may critically influence diagnosis, treatment, and prognosis. Second opinions constitute one of the largest expenditures of the supplementary health insurance programs provided by the Israeli health funds. The scarcity of data on physicians’ attitudes toward second opinion motivated this study to explore those attitudes within the Israeli healthcare system. Methods We interviewed 35 orthopedic surgeons and neurologists in Israel and qualitatively analyzed the data using the Grounded Theory approach. Results As a common tool, second opinion reflects the broader context of the Israeli healthcare system, specifically tensions associated with health inequalities. We identified four issues: (1) inequalities between central and peripheral regions of Israel; (2) inequalities between private and public settings; (3) implementation gap between the right to a second opinion and whether it is covered by the National Health Insurance Law; and (4) tension between the authorities of physicians and religious leaders. The physicians mentioned that better mechanisms should be implemented for guiding patients to an appropriate consultant for a second opinion and for making an informed choice between the two opinions. Conclusions While all the physicians agreed on the importance of the second opinion as a tool, they raised concerns about the way it is provided and utilized. To be optimally implemented, second opinion should be institutionalized and regulated. The National Health Insurance Law should strive to provide the mechanisms to access second opinion as stipulated in the Patient’s Rights Law. Further studies are needed to assess the patients' perspectives.

Abstract
The surgical management of Polyostotic Fibrous Dysplasia (FD) of bone is technically demanding. The most effective methods to manage the associated bone deformity remain unclear. The marked variation in the degree and pattern of bone involvement has made it difficult to acquire data to guide the surgeon’s approach to these patients. In light of the paucity of data, but need for guidance, recognized experts in the management of these patients came together at the National Institutes of Health in Bethesda, Maryland as part of an International meeting to address issues related to fibrous dysplasia of bone to discuss and refine their recommendations regarding the surgical indications and preferred methods for the management of these challenging patients. The specific challenges, recommended approaches, and “lessons learned” are presented in hopes that surgeons faced with typical deformities can be guided in the surgical reconstruction of both children and adults with FD.

Abstract
BACKGROUND The Proteus syndrome is characterized by the overgrowth of skin, connective tissue, brain, and other tissues. It has been hypothesized that the syndrome is caused by somatic mosaicism for a mutation that is lethal in the nonmosaic state. METHODS We performed exome sequencing of DNA from biopsy samples obtained from patients with the Proteus syndrome and compared the resultant DNA sequences with those of unaffected tissues obtained from the same patients. We confirmed and extended an observed association, using a custom restriction-enzyme assay to analyze the DNA in 158 samples from 29 patients with the Proteus syndrome. We then assayed activation of the AKT protein in affected tissues, using phosphorylation-specific antibodies on Western blots. RESULTS Of 29 patients with the Proteus syndrome, 26 had a somatic activating mutation (c.49G→A, p.Glu17Lys) in the oncogene AKT1, encoding the AKT1 kinase, an enzyme known to mediate processes such as cell proliferation and apoptosis. Tissues and cell lines from patients with the Proteus syndrome harbored admixtures of mutant alleles that ranged from 1% to approximately 50%. Mutant cell lines showed greater AKT phosphorylation than did control cell lines. A pair of single-cell clones that were established from the same starting culture and differed with respect to their mutation status had different levels of AKT phosphorylation. CONCLUSIONS The Proteus syndrome is caused by a somatic activating mutation in AKT1, proving the hypothesis of somatic mosaicism and implicating activation of the PI3K-AKT pathway in the characteristic clinical findings of overgrowth and tumor susceptibility in this disorder.

Abstract
PURPOSE To describe surgical outcomes using the new device in pediatric neuromuscular scoliosis. METHODS All patients with neuromuscular disorders requiring surgery with pelvic fixation for the correction of scoliosis in the period 2002-2009 were operated by the new pelvic rod fixation device. Coronal and sagittal alignment before and after surgery until the latest follow-up were evaluated by standard X-rays. Intraoperative and postoperative complications were recorded. RESULTS All 18 study patients (mean age at surgery 15 years, range 10-27) achieved solid fusion at a mean follow-up of 41 months. The coronal Cobb angle improved from 82° ± 31° (range 36-168) to 33° ± 25° at the last follow-up (range 9-95 months) (P < 0.0001). Pelvic obliquity improved from 19° ± 6° (range 10-30) to 5° ± 5° (range 0-14) (P < 0.0001). Early complications included pneumonia, urinary tract infection, disseminated intravascular coagulation (DIC), and hypovolemic shock. Three patients required debriding and received prolonged antimicrobial therapy for deep wound infection (none required implant removal). At the latest follow-up, no patient complained of lumbar pain or worsening of ambulatory status or level of activity. CONCLUSION Surgery employing the new pelvic rod fixation device allowed solid fusion and fixation with significant correction of multiplanar deformity, but the complication rate was high.

Abstract
Our aim was to evaluate the effect of adding inhibitory casting to the treatment of young children with cerebral palsy who received injections of botulinum neurotoxin A (BoNT-A) to gastrocnemius for equinus gait. Of the 20 patients in the series, 11 in group A had inhibitory casts applied on the day of the first set of BoNT-A injections and nine in group B did not have casting. Both groups received another BoNT-A injection four months later. The patients were followed for eight months and examined at five intervals. Both groups showed significant improvement in gait parameters and function (p < 0.0001) and selective motor control (p = 0.041, - 0.036) throughout the study. Group A had significantly better passive dorsiflexion of the ankle (p = 0.029), observational gait score (p = 0.006) and selective motor control (p = 0.036). We conclude that the addition of inhibitory casting enhances and prolongs the results of treatment and mainly influences the passive range of movement, while BoNT-A mostly influences the dynamic motion. The second injection further improved the results of most parameters. The gross motor function measure, the selective motor control test and the modified Tardieu scale correlated well with the results of treatment. We recommend the use of inhibitory casting whenever augmentation of the effect of treatment with BoNT-A is needed.

Abstract
The role of heritable thrombophilic risk factors in the pathogenesis of the Perthes' disease is controversial. The clinical and radiological findings of Perthes' disease may be indistinguishable from those of Gaucher's disease, and the most common Jewish N370S Gaucher mutation is threefold greater in patients with Perthes' disease. Familial osteonecrosis of the femoral head is associated with variant mutations of collagen type II (COL2A1 mutations). We therefore studied the potential role of genetic thrombophilia and the Gaucher and COL2A1 mutations in children with Perthes' disease. Genomic DNA of 119 children with radiologically-confirmed Perthes' disease diagnosed between 1986 and 2005 was analysed for the thrombophilic polymorphisms Factor V Leiden, 677T-MTHFR and FIIG20210A. The results were compared with those of a group of 276 children without Perthes' disease. DNA was also analysed for the Gaucher mutations N370S, G insertion (84GG), L444P, Intron 2 (IVS2+1G>A) and R496H. Enzymic assays confirmed the Gaucher disease status. Collagen (COL2A1) mutations of the 12q13 gene were also analysed. The prevalence of thrombophilic markers was similar among the 119 patients with Perthes' disease and the 276 control subjects. The prevalence of the Gaucher mutation was consistent with Israeli population carriership data and did not confirm an earlier-claimed association with Perthes' disease. All 199 patients were negative for the studied COL2A1 mutations. We found no genetic association between Perthes' disease and either Gaucher's disease or COL2A1 mutations or increased genetic thrombophilia among our patients compared with the control group. A systematic review of case-control studies suggested that there was a positive association between Perthes' disease and Factor V Leiden. The impact of this association upon the disease, although not consistent across the studies, remains unclear.

Abstract
PURPOSE To report the treatment outcomes of V osteotomy and Ilizarov technique for residual idiopathic or neurogenic clubfeet. METHODS 13 patients (14 feet) aged 8 to 18 years underwent V osteotomy via the calcaneus and talus, followed by gradual distraction of soft tissue and bone for foot reconstruction. Eight of the clubfeet were idiopathic and had undergone previous surgeries. The remaining 6 were neurogenic and their pathologies were: Charcot-Marie-Tooth disease (n=2), myelomeningocele (n=2), neurofibromatosis (n=1), and distal arthrogryposis (n=1). Three of them had undergone previous surgeries. The Ilizarov frames were retained for 3 to 6 months and the patients were followed up for 1.8 to 8.9 years. Range of movement of the ankle and foot, appearance and position, gait, pain, function, and patient satisfaction were assessed according to the modified clubfoot grading system. The talo-1st metatarsal angle was measured on anteroposterior radiographs. RESULTS Scores associated with the appearance and position of the foot, and thus patient satisfaction were significantly improved, but not for range of movement, pain, and function. The mean preoperative and final talo-1st metatarsal angles were 39.7 and 8.7 degrees, respectively (p<0.01). Ten feet achieved the plantigrade position, one had residual equinus, and 3 had residual adduction and supination. CONCLUSION Patient satisfaction improved significantly despite no major improvement in pain, function, and range of movement of the ankle and foot. This reflects the importance of the appearance and position of the foot, and justifies the decision to undergo this long and demanding procedure.

Abstract
BACKGROUND Musculoskeletal manifestations (MMs) are considered to be rare in cat scratch disease (CSD) and are not well characterized. We aimed to study MMs of CSD. METHODS A surveillance study performed over 11 years identified patients with CSD on the basis of compatible clinical presentation and confirmatory serological test or PCR results for Bartonella henselae. Patients with CSD who had MMs (i.e., myalgia, arthritis, arthralgia, tendinitis, osteomyelitis, and neuralgia) were compared with patients with CSD who did not have MMs (control subjects). RESULTS Of 913 patients with CSD, 96 (10.5%) had MMs. Myalgia (in 53 patients [5.8%]) was often severe, with a median duration of 4 weeks (range, 1-26 weeks). Arthropathy (arthralgia and/or arthritis; in 50 patients [5.5%]) occurred mainly in the medium and large joints and was classified as moderate or severe in 26 patients, with a median duration of 5.5 weeks (range, 1-240 weeks). In 7 patients, symptoms persisted for >or=1 year; 5 developed chronic disease. Tendinitis, neuralgia, and osteomyelitis occurred in 7, 4, and 2 patients, respectively. Patients with MMs were significantly older than patients in the control group (median age, 31.5 years vs. 15.0 years). In multivariate analysis, age >20 years was associated with having any MM (relative risk [RR], 4.96; 95% confidence interval [CI], 2.79-8.8), myalgia (RR, 4.69; 95% CI, 2.22-9.88), and arthropathy (RR, 11.0; 95% CI, 4.3-28.2). Arthropathy was also associated with female sex (RR, 1.89; 95% CI, 1.01-3.52) and erythema nodosum (RR, 4.07; 95% CI, 1.38-12.02). CONCLUSIONS MMs of CSD are more common than previously thought and affect one-tenth of patients with CSD. MMs occur mostly in patients aged >20 years and may be severe and prolonged. Osteomyelitis, the most well known MM of CSD is, in fact, the rarest.

Abstract
PURPOSE To prospectively evaluate long-term effects of repeated botulinum toxin A (BTX-A) injections in children with cerebral palsy (CP). METHODS Repeated injections of BTX-A were offered to children with CP, according to clinical indications, for a maximum of four injections within a period of two years. Injections were administered into lower extremity muscles of 26 consecutive children (age 3.7 +/- 1.2 years, 16 boys) with hemiplegic or diplegic CP. Clinical assessments before and one month following each injection included a gross motor function measure (GMFM), a modified Ashworth scale, and range-of-motion of knee extension and ankle dorsiflexion. RESULTS Twelve children received two injections, six received three injections, five received one injection, and three received four injections. The most common reason for discontinuing treatment was the need for orthopedic surgery (n = 17). A long-term effect was demonstrated by a significant increase of the GMFM score before the first injection compared with the last injection for each patient (P < 0.0001). There was no comparable change in the muscle tone or range-of-motion. The mean rate of GMFM change during the study was significantly higher than literature norms for CP children (13.2 vs. 5.37 per year, respectively, P < 0.01). The increase of the GMFM score before and one-month after injection (short-term effect) was significantly higher after the first injection than after the last injection (P < 0.05). Similar results were found for the Ashworth scale and popliteal angle. CONCLUSIONS Botulinum toxin A injections have a long-term effect on gross motor function in children with CP even though the effect on muscle tone is short-term. The effect apparently declines with repeated injections, with most children benefitting from 2 to 3 injections.

Abstract
PURPOSE Late-onset Perthes' disease is diagnosed after 9 years of age. Conservative treatment and conventional surgical techniques have limited ability to reduce the pressure in the joint or change the shape of the femoral head. We used a combination of soft tissue release and joint distraction with a hinged mono-lateral external fixator for these patients. Ten of our patients reached skeletal maturity and were evaluated. METHODS Clinical assessment included: Harris hip score, hip range-of-motion (ROM), limb length discrepancy, and the Oxford hip questionnaire for pain and function. Radiographic assessment included: Sharp transverse acetabular inclination, the uncoverage percentage, the epiphyseal index before surgery (modified Eyre-Brook), at frame removal, and, at last follow-up, the epiphyseal quotient (of Sjovall) and the Stulberg classification. RESULTS Our study included eight boys and two girls (mean age at surgery 12.3 years, range 9.4-15.1, mean age at last follow-up 18.1 years, range 15.2-22.8). The mean follow-up was 5.7 years (range 4.3-7.8). The mean Harris hip score was 86.3/100 (range 48.5-96); one patient had <85 points. The hip ROM was slightly limited in most patients, and seven patients had limb shortening between 1-4 cm. The mean Oxford hip questionnaire score was 17.4/60 (range 12-31). The mean Sharp transverse acetabular inclination of the affected side was 42 degrees (range 36-54) compared to 39 degrees for the unaffected side (P = 0.045). The mean uncoverage percentage was 37% (range 27-47) compared to 20% for the unaffected side (P = 0.017). The mean epiphyseal index was 0.71 (range 0.31-0.92) before surgery, 0.79 (range 0.50-0.93) at frame removal (P = 0.012), and 0.72 (range 0.51-0.89) at last follow-up (P = 0.646). The epiphyseal quotient for the eight unilateral cases was 0.72 (range 0.49-0.91), and the Stulberg classification was type III for three cases and type IV for seven. CONCLUSION Patient satisfaction for function and pain following the combined procedure was good. Radiographic parameters did not change significantly. This should be regarded as a salvage procedure.

Abstract
PURPOSE To describe a combined use of a free vascularised flap and an external fixator for reconstruction of lower extremity defects in children, and correction of equinus contracture developed after removal of the external fixator using a circular dynamic frame. METHODS Seven children (4 males) aged 4 to 12 (mean, 8) years were treated with 9 free vascularised flaps for 8 limbs (bilaterally in one patient and for a failed flap in another). Patient pathologies included: 3 soft tissue degloving injuries, one soft tissue and bone avulsion, one severe burn contracture, one resurfacing of soft tissue and bone necrosis, and one osteosarcoma resection defect. Free flap reconstruction was delayed in 6 patients (range, 3 weeks to 4 years). Static external fixators were used to stabilise the free vascularised flaps at the time of reconstruction, with the ankle in a neutral position. RESULTS The mean follow-up was 5 (1-10) years. All flaps but one survived; the failed one was immediately reconstructed with a contralateral, latissimus dorsi flap. One anastomosis following a Kirschner-wire injury was successfully revised. Six patients had pin tract infections and were treated with oral antibiotics. Two patients developed equinus contracture 6 and 3 years later, after removal of the external fixator, and were corrected by distraction, using a dynamic Ilizarov frame. CONCLUSION The combined use of a free flap and an external fixator for salvage of lower extremities is useful in children. Late development of equinus contracture can be safely corrected by distraction, without compromising flap viability.

Abstract
The aim of the present study was to assess the ability of a novel bone imaging technique to diagnose accurately the cause for back pain as an isolated and presenting complaint in adolescents. An integrated 18F-fluoride positron-emission tomography-computed tomography (PET-CT) study was performed at the same setting without changing the patients' position, followed by generation of fused images of functional and anatomical data. Fifteen subjects were included in the study. The interpretation of PET-CT fused images was based on increased 18F-fluoride uptake and the corresponding CT-located abnormality. Ten patients had positive findings that included 4 cases of spondylolysis (3 of them active), 3 frank fractures (2 of the transverse process and 1 of the facet), 2 osteoid osteomas, 1 osteitis pubis, 1 sacroiliitis, and 2 herniated disks. Three patients presented 2 coexisting pathologies. Treatment was tailored based on final diagnosis. In 5 patients, in whom no abnormality was identified, the back pain resolved spontaneously. The 18F-fluoride PET-CT can detect spinal lesions with high diagnostic accuracy in adolescents with back pain. Considering the associated costs and radiation exposure, it should be used at present only in cases of long-standing and disabling back pain in which other imaging modalities were inconclusive.

Abstract
This study was undertaken to review our approach to diagnosis and treatment in a series of 11 patients (mean age 8.2 years) with primary pyomyositis, who had neither an underlying disease nor a compromised immune system. Nine of the children had positive blood cultures, Staphylococcus aureus (eight) and Streptococcus group A (one). The sites of infection were iliopsoas (four), obturator (two), hip adductors (two), levator scapula (one), thoracolumbar paraspinal (one) and gastrocnemius (one) muscles. Antibiotic treatment was initially intravenous, followed by oral administration. Of five patients with evidence of abscess formation, three underwent percutaneous drainage, whereas two required open surgical drainage. The infection resolved completely without any sequela in 10 children. One patient who developed acute compartment syndrome showed late signs of osteonecrosis of the tibial shaft segment.

Abstract
Idiopathic clubfoot, one of the most common problems in pediatric orthopaedics, is characterized by a complex three-dimensional deformity of the foot. The treatment of clubfoot is controversial and continues to be so. Since nonsurgical management was thought not to yield adequate correction and a durable result, most children with idiopathic clubfoot have undergone surgery with extensive posteromedial and lateral release. However, surgical management caused residual deformity, stiffness, and pain in some children. Therefore, the favorable long-term results with the Ponseti and French methods of nonsurgical management have garnered interest. Today extensive surgical treatment is no longer necessary in more then 90% of congenital clubfeet. This review aims to assess the different methods of clubfoot treatment used over the years in light of an evolving understanding of the pathoanatomy of the deformity and also clarify factors that allow a safe, logical approach to clubfoot management.

Radiation-free quantitative assessment of scoliosis: a multi center prospective study. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2006; 16:97-105. [PMID: 16705434 PMCID: PMC2198878 DOI: 10.1007/s00586-006-0118-8] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2005] [Revised: 02/15/2006] [Accepted: 02/22/2006] [Indexed: 10/24/2022]
Abstract
Accurate quantitative measurements of the spine are essential for deformity diagnosis and assessment of curve progression. There is much concern related to the multiple exposures to ionizing radiation associated with the Cobb method of radiographic measurement, currently the standard procedure for diagnosis and follow-up of the progression of scoliosis. In addition, the Cobb method relies on 2-D analysis of a 3-D deformity. The aim of this prospective study was to investigate the clinical value of Ortelius800 that provides a radiation-free method for scoliosis assessment in three planes (coronal, sagittal, apical), with simultaneous automatic calculation of the Cobb angle in both coronal and sagittal views. Analysis of the clinical value of the device for assessing spinal deformities was performed on patients with adolescent idiopathic scoliosis, deformity angles ranging from 10 degrees to 48 degrees. Correlation between Cobb angles measured manually on standard erect posteroanterior radiographs and those calculated by Ortelius800 showed an absolute difference between the measurements to be significantly less than +/- 5 degrees for coronal measurements and significantly less than +/- 6 degrees for sagittal measurements indicating good correlation between the two methods. The measurements from four independent sites and six independent examiners were not significantly different. We found the novel clinical tool to be reliable for following mild and moderate idiopathic curves in both coronal and sagittal planes, without exposing the patient to ionizing radiation. Considering the need for further validation of this new method, any change in treatment protocol should still be based on radiographic control.

Abstract
BACKGROUND Polyostotic fibrous dysplasia has a wide clinical spectrum, with substantial variation between patients in terms of orthopaedic manifestations, including the number of fractures, the degree of deformity of the limbs, and the presence of scoliosis. Data from bone scans, skeletal surveys, and records were correlated with the Pediatric Outcomes Data Collection Instrument scales to examine whether any specific facet of orthopaedic involvement could be related to functional abilities. METHODS All patients who were sixteen years of age or younger and who were part of an ongoing natural history study of polyostotic fibrous dysplasia (including McCune-Albright syndrome) were sent an age-appropriate Pediatric Outcomes Data Collection Instrument outcomes tool. The medical records and radiographs of the patients who returned forms were reviewed. Radiographic measurements of scoliosis, the femoral neck-shaft angle, and limb deformities were then performed. The extent of skeletal involvement with polyostotic fibrous dysplasia (disease burden) was assessed on bone scans with use of a validated tool. A chart review was performed to determine the fracture rate, the use of bisphosphonates, and the endocrine status. These measurements were correlated with the Pediatric Outcomes Data Collection Instrument scores. RESULTS The outcomes tool was sent to twenty-seven patients and the completed instrument was returned by twenty patients, for a response rate of 74%. The parent-child form was filled out for twelve patients and the parent-adolescent form was filled out for eight patients. The mean standardized Pediatric Outcomes Data Collection Instrument scores for all twenty patients were lowest for sports (62; range, 14 to 100) and happiness (72; range, 25 to 100). Adolescents and parents disagreed with regard to sports (with adolescent scores being higher than parental scores) and pain (with parental scores being higher than adolescent scores). However, the overall global scores correlated well between the parents and the adolescents (r = 0.78, p = 0.03). The femoral neck-shaft angle correlated strongly with the Pediatric Outcomes Data Collection Instrument score for sports (r = 0.46, p = 0.03) but not for transfers. The bone scan scores for the lower extremity disease burden correlated with both the transfer scale (r = 0.76, p = 0.03) and the sports scale (r = 0.77, p = 0.02). Deformity of the limbs, the presence of scoliosis, the prevalence of endocrine dysfunction, and the number of fractures did not correlate with the Pediatric Outcomes Data Collection Instrument scores. CONCLUSIONS In patients with polyostotic fibrous dysplasia, the loss of the normal femoral neck-shaft angle and the disease burden in the lower extremities appear to have the greatest effect on functional activity as measured with the Pediatric Outcomes Data Collection Instrument tool.

Abstract
OBJECTIVE To characterize the articular manifestations of cat-scratch disease (CSD) and to evaluate the long-term clinical outcome of those manifestations. METHODS A community- and hospital-based surveillance study of CSD was conducted in Israel between 1991 and 2002. CSD was defined as present in a patient when a compatible clinical syndrome and a positive confirmatory finding of Bartonella henselae (by serology and/or polymerase chain reaction) were identified. CSD patients with arthropathy (arthritis/arthralgia) that limited or precluded usual activities of daily living constituted the study group. Patients were followed up until > or =6 weeks after resolution of symptoms, or if symptoms persisted, for >/=12 months. CSD patients without arthropathy served as controls. RESULTS Among 841 CSD patients, 24 (2.9%) had rheumatoid factor-negative arthropathy that was often severe and disabling. Both univariate and multivariate analyses identified female sex (67% of arthropathy patients versus 40% of controls; relative risk [RR] 2.5, P = 0.047), age older than 20 years (100% of arthropathy patients versus 43% of controls; RR 4.9, P = 0.001), and erythema nodosum (21% of arthropathy patients versus 2% of controls; RR 7.9, P = 0.001) as variables significantly associated with arthropathy. Knee, wrist, ankle, and elbow joints were most frequently affected. Ten patients (42%) had severe arthropathy in the weight-bearing joints, which substantially limited their ability to walk, and 4 of these patients were hospitalized. All of the patients had regional lymphadenopathy, 37.5% had nocturnal joint pain, and 25% had morning stiffness. Nineteen patients (79.2%) recovered after a median duration of 6 weeks (range 1-24 weeks), whereas 5 patients (20.8%) developed chronic disease persisting 16-53 months (median 30 months) after the onset of arthropathy. CONCLUSION This is the first comprehensive study of arthropathy in CSD. CSD-associated arthropathy is an uncommon syndrome affecting mostly young and middle-age women. It is often severe and disabling, and may take a chronic course.

Abstract
Camurati-Engelmann disease (CED) is a rare autosomal dominant type of bone dysplasia. This review is based on the unpublished and detailed clinical, radiological, and molecular findings in 14 CED families, comprising 41 patients, combined with data from 10 other previously reported CED families. For all 100 cases, molecular evidence for CED was available, as a mutation was detected in TGFB1, the gene encoding transforming growth factor (TGF) beta1. Pain in the extremities was the most common clinical symptom, present in 68% of the patients. A waddling gait (48%), easy fatigability (44%), and muscle weakness (39%) were other important features. Radiological symptoms were not fully penetrant, with 94% of the patients showing the typical long bone involvement. A large percentage of the patients also showed involvement of the skull (54%) and pelvis (63%). The review provides an overview of possible treatments, diagnostic guidelines, and considerations for prenatal testing. The detailed description of such a large set of CED patients will be of value in establishing the correct diagnosis, genetic counselling, and treatment.

Abstract
BACKGROUND The preferred conservative treatment for congenital idiopathic clubfoot deformity remains a controversial issue. OBJECTIVES To compare the outcomes of two groups of CICF patients who underwent two different treatment protocols. METHODS The study cohort included 72 infants treated in our hospital from August 1998 to December 2002. Group 1 comprised 40 infants (61 clubfeet) who were treated by a traditional method (a modification of the Kite and Lovell technique), and group 2 consisted of 32 infants (48 clubfeet) treated with the Ponseti technique. Both groups were similar in age, gender and severity of the deformity (Dimeglio scoring system). RESULTS After an average follow-up of 54.9 months (range 44-68), 35 (57%) clubfeet in group 1 required surgical intervention and 27 (44%) clubfeet had a residual deformity at last follow-up. In the Ponseti group, 45 (94%) clubfeet were fully corrected at last follow-up (average 29.2 months, range 16-45) while 3 (6%) clubfeet had residual deformity and required surgery. Achilles tendon tenotomy was performed with no complications in 47 clubfeet (in group 2) at an average age of 2.4 months (range 2-4 months). CONCLUSIONS Even after a relatively short follow-up period, our success rate with the Ponseti approach already appears to be significantly higher and to bear fewer complications than the traditional treatment, in agreement with the results published by other medical centers. We now endorse the Ponseti technique of conservative manipulative treatment for congenital idiopathic clubfoot in our department.

An instrument to measure skeletal burden and predict functional outcome in fibrous dysplasia of bone. J Bone Miner Res 2005; 20:219-26.

Abstract
UNLABELLED An instrument to measure skeletal burden in fibrous dysplasia was developed. Biological and clinical relevance was shown by correlating skeletal burden scores with bone markers, quality of life, and ambulatory status. Childhood scores predict adult ambulatory status, and scores were unaffected when bone markers decreased with bisphosphonate treatment or aging. INTRODUCTION Fibrous dysplasia (FD) is a skeletal disease with a broad clinical expression. There is no objective method to assess the extent of skeletal involvement or predict outcome. We developed an instrument to measure skeletal burden that correlates with physical function, health-related quality of life (HRQL), and ambulatory status. MATERIALS AND METHODS Seventy-nine patients with FD underwent bone scintigraphy. The skeletal burden score was derived from a weighted score based on the regional measurement using bone scintigraphy to estimate the amount of FD in anatomical segments. Six readers scored 20 scans twice to determine the inter- and intrareader agreement. To assess biological significance, scores were correlated with bone markers. To assess functional outcome, scores on the SF-36 (adults) or CHQ-PF50 (children) were correlated with skeletal burden scores. In a group of patients who had bone scans as children and adults (n = 6), the ability to predict ambulatory status was tested. Skeletal burden scores were assessed in patients before and after treatment with pamidronate (n = 5). RESULTS The inter- and intrareader agreement of burden scores were r = 0.96, and 0.98, respectively (p < 0.001 for both). The scores correlated with markers of bone metabolism and HRQL (Spearman rho, 0.54-0.67 p < 0.001 and -0.43, p = 0.001, respectively). The mean score of patients who ambulated unassisted was significantly lower than those requiring assistance (p < 0.001 unassisted versus crutch and/or wheelchair). In unassisted ambulators, younger patients had higher scores, suggesting high childhood scores may predict adulthood impairment. In six patients with childhood and adulthood scans, childhood scores >30 predicted assisted ambulation in adulthood. There was a negative correlation between bone markers and age (Spearman rho, -0.42 to -0.70; p < 0.001), but not age and skeletal burden score. Pamidronate treatment decreased serum alkaline phosphatase but had no effect on the skeletal burden score. CONCLUSIONS This is a validated and reliable instrument for the measurement of skeletal burden of FD and is able to predict functional outcome.

Abstract
BACKGROUND Bladder exstrophy is a severe congenital defect that requires a multidisciplinary treatment approach. Soft tissue repair may be successful during the first few days after birth, but a combination of pelvic osteotomies and bladder reconstruction is necessary later in life. The combination of externally fixed anterior and posterior osteotomies has biomechanical advantages over previous techniques for achieving primary bladder closure. OBJECTIVES To describe our experience with a combined vertical and horizontal pelvic osteotomy approach for the repair of bladder exstrophy. METHODS Four children underwent bladder exstrophy closure; the mean age at surgery was 19 months (range 9-33 months)... We stabilized the osteotomies with a small Synthes AO external fixator, 4.0 mm rod diameter. RESULTS All four patients had successful bladder repair with no dehiscence; two of them achieved partial continence, and bladder neck reconstruction is planned for the other two. Three of the four patients sustained neurologic injury; two completely recovered, and the third continues to suffer from right drop foot. The average follow-up was 39 months (range 10-60 months). CONCLUSIONS Vertical and horizontal pelvic osteotomies stabilized by external fixator and bladder repair is an effective treatment for bladder exstrophy.
