Reliability of the Clinical Measurement of Upper and Lower Extremity Joint Motion in the Pediatric Population: A Systematic Review.

AIM: To examine intraobserver and interobserver reliability of the clinical measurement of pediatric joint motion of upper and lower extremities, based on participant condition and measurement technique. METHODS: PubMed, CINAHL, and Web of Science were searched using combinations of children or adolescents, range of motion, and reliability. Reference lists and citations of reviewed studies were searched for additional publications. RESULTS: Thirty-one studies of pediatric samples of developing typically, orthopedic injuries, athletes, cerebral palsy, and other diagnoses were reviewed. For techniques, measurements were made most frequently with a goniometer followed by visual estimation, inclinometer, smartphone apps, and specialized devices. The reliability of hip abduction measurements of participants with cerebral palsy was evaluated most often and varied widely for both intraobserver and interobserver. In general, goniometric results indicated greater reliability for upper than lower extremities and for intraobserver than interobserver. As the other techniques were each utilized in only a few studies, involving different participant conditions, joint motions and statistics, the analysis of their reliability was limited. CONCLUSIONS: Intraobserver and interobserver reliability have not been established for pediatric joint motion measurements. Further research should include various joint motion measurements for different pediatric conditions using appropriate statistics. Results would provide important information for making clinical decisions.

Design and Use of a 3D-Printed Dynamic Upper Extremity Orthosis for Children With Cerebral Palsy and Severe Upper Extremity Involvement: A Pilot Study.

IMPORTANCE: Children with cerebral palsy (CP) and severe hand impairment have limited options for upper extremity (UE) orthoses. OBJECTIVE: To (1) design and fabricate a customized low-cost, functional, three-dimensional (3D) printed dynamic upper extremity orthosis (DUEO) and (2) examine, using a comprehensive evaluation, the effect of the orthosis on the UE function of children with unilateral UE CP, Manual Ability Classification System (MACS) Levels III to V. DESIGN: Pilot study. Assessments were performed pretreatment and immediately posttreatment. SETTING: Hospital-based outpatient occupational therapy department. PARTICIPANTS: Five patients, ages 13 to 17 yr, with CP and unilateral UE involvement MACS Levels III to V. INTERVENTION: Custom forearm thumb opponens orthosis and the DUEO were designed and fabricated by a multidisciplinary team for use during eight 1-hr occupational therapy sessions targeting bimanual UE training. OUTCOMES AND MEASURES: Pretreatment and posttreatment assessments included the Assisting Hand Assessment (AHA), Melbourne Assessment 2 (MA-2), Pediatric Motor Activity Log-Revised (PMAL-R), and the Pediatric Quality of Life Inventory: CP Module (PedsQL:CP). RESULTS: All participants had higher posttreatment scores on at least one measure. Four had minimal clinically important differences (MCID) on the AHA. Three met MCID criteria on MA-2 subtests (one negative change). Four demonstrated improvement on the PMAL-R (one participant achieved an MCID score), and three reported improvements in more than one PedsQL:CP domain. CONCLUSIONS AND RELEVANCE: This novel 3D-printed device, in combination with occupational therapy, shows promising evidence that children who score in lower MACS levels can show gains in UE function. What This Article Adds: This study demonstrates that a customized, 3D-printed dynamic orthosis, in combination with occupational therapy intervention, can facilitate UE function in children with severe hand impairment.

Transition program: Initial implementation with adults with neuromuscular conditions.

PURPOSE: To identify current medical and psychosocial needs and to examine the effectiveness of healthcare transition program for adult-aged patients with neuromuscular conditions transitioning from pediatric to adult services. DESIGN AND METHODS: At Neuromuscular Transition Clinic visit, 46 patients were evaluated and referred to adult-based providers, if did not currently have one, from an acquired list of interested clinicians. At mean follow-up of 22 months, 42 were interviewed by phone regarding referrals for Core Services (primary care, physiatry, dental care and gynecology), Medical Specialties and Rehabilitation Services. Mean age was 30 years with 62% males. Majority (74%) had cerebral palsy. Sixty percent were non-ambulatory. RESULTS: As per protocol, all were indicated to need Core Services. Eighty-three percent already had adult primary care provider. Most referrals were given for physiatry (62%), vocational training (100%), and occupational therapy (88%). At follow-up, visits were completed most frequently with adult provider for primary care (100%), occupational therapy (78%), and neurology (75%). Referred provider was seen 100% for physiatry, neurology, physical therapy, occupational therapy and vocational training. Of the total 125 referrals given across all services, 73 (58%) participants had completed a visit with an adult provider. CONCLUSIONS: As only about 60% transitioned to adult-based services after referral, healthcare transition remains challenging and requires tailoring of services according to patients' needs, staff and willing-and-available adult-based providers. PRACTICE IMPLICATIONS: Transitioning healthcare of patients with neuromuscular conditions from pediatric- to adult-based providers remains challenging. This clinical specialty requires tailoring of services based on patient's needs, and availability of adult-based providers and resources.

Impact of tranexamic acid on blood loss and transfusion rate in children with cerebral palsy undergoing hip reconstruction with two or more osteotomies.

PURPOSE: Tranexamic acid (TXA), a synthetic lysine analogue, has been used in orthopedic procedures to limit blood loss and prevent allogeneic blood transfusions. However, data are scarce on its use in hip reconstruction of patients with cerebral palsy (CP). This study examines the effect of TXA on patients with CP undergoing hip reconstruction with at least two osteotomies. METHODS: This is a single-center, retrospective study of patients with CP who underwent hip reconstruction with two or more osteotomies from January 2013 to April 2019. There were 43 patients, with a mean age of 9.9 years. Age, procedure, preoperative and postoperative hemoglobin/hematocrit, estimated blood loss (EBL), transfusions and length of stay were recorded. The patients were split into the following two groups: 24 patients who had received intraoperative TXA and 19 who had not. RESULTS: Age, EBL, mean preoperative and postoperative hemoglobin or hematocrit, preoperative to postoperative hematocrit drop, and length of stay were similar for the two groups (p > 0.05). The risk for intraoperative transfusion (21 vs. 17%), postoperative transfusion (26 vs. 8%), and any transfusion (42 vs. 21%) appeared to be greater in the group that did not receive TXA, but this difference did not achieve statistical significance. CONCLUSION: This pilot study shows patients with CP undergoing hip reconstruction with two or more osteotomies; the use of TXA, while not statistically significant, shows a trend toward a decreased need for allogeneic blood transfusion.

Measuring ambulation with wrist-based and hip-based activity trackers for children with cerebral palsy.

AIM: To assess the accuracy of consumer available wrist-based and hip-based activity trackers in quantitatively measuring ambulation in children with cerebral palsy (CP). METHOD: Thirty-nine children (23 males, 16 females; mean age [SD] 9y 7mo [3y 5mo]; range 4-15y) with CP were fitted with trackers both on their wrist and hip. Each participant stood for 3 minutes, ambulated in a hallway, and sat for 3 minutes. The number of steps and distance were recorded on trackers and compared to manually counted steps and distance. Pearson correlation coefficients were determined for the number of steps during ambulation from each tracker and a manual count. Mean absolute error (MAE) and range of errors were calculated for steps during ambulation for each tracker and a manual count and for distance for each tracker and hallway distance. RESULTS: For the number of steps, a weak inverse relationship (r=-0.033) was found for the wrist-based tracker and a strong positive relationship (r=0.991) for the hip-based tracker. The MAE was 88 steps for the wrist-based and seven steps for the hip-based tracker. The MAE for distance was 0.06 miles for the wrist-based and 0.07 miles for the hip-based tracker. INTERPRETATION: Only the hip-based tracker provided an accurate step count; neither tracker was accurate for distance. Thus, ambulation of children with CP can be accurately quantified with readily available trackers. WHAT THIS PAPER ADDS: Consumer available activity trackers accurately measure ambulation in children with cerebral palsy (CP). The hip-based tracker is more accurate than the wrist-based tracker for children with CP. The hip-based Fitbit activity tracker accurately measures step counts of children with CP during ambulation.

MEDICIÓN DE LA AMBULACIÓN CON RASTREADORES DE ACTIVIDAD DE MUÑECA Y CADERA PARA NIÑOS CON PARÁLISIS CEREBRAL: OBJETIVO: Evaluar la precisión de los rastreadores de actividad basados ​​en la muñeca y en la cadera disponibles para el consumidor en la medición cuantitativa de la ambulación en niños con parálisis cerebral (PC) METODO: Treinta y nueve niños (23 varones, 16 mujeres; edad media [DS] 9 años y 7 meses [3 años y 5 meses]; rango 4-15 años) con PC fueron equipados con rastreadores en su muñeca y cadera. Cada participante se paró durante 3 minutos, caminó por un pasillo y se sentó durante 3 minutos. La cantidad de pasos y la distancia se registraron en los rastreadores y se compararon con los pasos y la distancia contados manualmente. Los coeficientes de correlación de Pearson se determinaron para el número de pasos durante la ambulación de cada rastreador y un conteo manual. El error absoluto medio (MAE) y el rango de errores se calcularon para los pasos durante la ambulación y la distancia del pasillo para cada rastreador y para el conteo manual. RESULTADOS: Para el número de pasos, se encontró una relación inversa débil (r = -0.033) para el rastreador ubicado en la muñeca y una relación positiva fuerte (r = 0.991) para el rastreador ubicado en la cadera. El MAE fue de 88 pasos para la muñeca y siete pasos para el rastreador de la cadera. El MAE para la distancia fue de 0.06 millas para la muñeca y 0.07 millas para el rastreador ubicado en la cadera. INTERPRETACIÓN: Solo el rastreador ubicado en la cadera proporcionó un conteo de pasos preciso; ninguno de los rastreadores era preciso para la distancia. Por lo tanto, la deambulación de los niños con PC se puede cuantificar con precisión con rastreadores fácilmente disponibles.

MEDINDO A DEAMBULAÇÃO COM RASTREADOR DE ATIVIDADE POSICIONADO NO PUNHO E QUADRIL COMERCIALMENTE DISPONÍVEL EM CRIANÇAS COM PARALISIA CEREBRAL: OBJETIVO: Avaliar a precisão de rastreadores de atividade posicionados no punho e quadril, disponíveis para o consumidor, para mensurar qualitativamente a deambulação em crianças com paralisia cerebral (PC). MÉTODO: Trinta e nove crianças (23 meninos, 16 meninas; média da idade [DP] 9 anos e 7 meses [3 anos e 5 meses]; amplitude 4-15 anos) com PC foram equipados com rastreadores em punho e quadril. Cada participante permaneceu em pé durante 3 minutos, andando em um corredor, e sentado por 3 minutos. O número de passos e distância foram registrados nos rastreadores e comparados com os passos e distância medidos manualmente. Coeficientes de correlação de Pearson foram determinados para o número de passos durante a deambulação para cada rastreador e a contagem manual. O Erro Médio Absoluto (EMA) e variância de erros foram calculados para os passos durante a deambulação para cada rastreador e a contagem manual e para a distância de cada rastreador e a distância do corredor. RESULTADOS: Para o número de passos, uma relação inversa fraca (r=-0,033) foi encontrada entre o rastreador do punho e uma relação positiva forte (r=0,991) para o reastreador do quadril. A EMA foi de 88 passos para o rastreador do punho e sete passos para o rastreador do quadril. A EMA para a distância foi de 0,06 milhas (9,66km) para o rastreador do punho e 0,07 milhas (11,26km) para o rastreador do quadril. INTERPRETAÇÃO: Somente o rastreador do quadril forneceu a contagem precisa dos passos; nenhum rastreador foi preciso para a distância. Assim, a deambulação em crianças com PC pode ser quantificada com precisão com os rastreadores atualmente disponíveis.

The Validity of Patient-reported Outcome Measurement Information System (PROMIS) Parent Proxy Instruments to Assess Function in Children With Talipes Equinovarus.

BACKGROUND: Idiopathic talipes equinovarus (ITEV) is a prevalent structural deformity of the foot and ankle in children. The disease-specific instrument (DSI) has commonly been used as an outcomes metric in these patients. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to examine the quality of life across various medical conditions. PROMIS has been validated for multiple conditions; however, no studies have evaluated the use of the PROMIS in children with ITEV. METHODS: A prospective analysis was performed whereby the 2 questionnaires were mailed out to the parents of 91 patients, aged 5 to 17 years, with ITEV. Construct validity of the PROMIS Parent Proxy Profile short forms version was assessed by comparing its domains of Mobility, Fatigue, Pain Interference, and Pain Intensity to the DSI Function domain and PROMIS domains of Anxiety, Depressive Symptoms, Peer Relationships, and Pain Intensity to DSI Satisfaction domain. RESULTS: Thirty-one complete responses (34% response rate) were returned. The patients' current mean age was 8.8 years, 7 were female individuals, and 12 had unilateral ITEV. Bivariate correlation analysis, using Spearman correlation coefficients, demonstrated a moderate positive correlation between the DSI Function domain and the PROMIS Mobility domain (rs=0.52) and a moderate negative correlation between the DSI Function domain and the PROMIS Pain Interference domain (rs=-0.56), as well as the PROMIS Pain Intensity domain (rs=-0.75). A fair negative correlation (rs=-0.38) with PROMIS Fatigue domain was found. Correlations between the DSI Satisfaction domain and the PROMIS domains were fair or had little relationship. CONCLUSIONS: These results provide support for the validity of the PROMIS Mobility, Pain Interference, and Pain Intensity domains in this population, however there are no items in PROMIS that can assess overall satisfaction, as with the DSI. LEVEL OF EVIDENCE: Level II-prospective comparative study.

Not All Hip Dysplasias are the Same: Preoperative CT Version Study and the Need for Reverse Bernese Periacetabular Osteotomy.

BACKGROUND: Dysplastic hip may present with acetabular retroversion with or without femoral retroversion. This retroversion, if not accounted for when performing a periacetabular osteotomy (PAO), will lead to anterior hip pain and early osteoarthritis. A reverse PAO involves anteverting the acetabulum while still obtaining lateral coverage. The purpose of this study was to investigate the relationship between rotational malalignment of acetabulum and femur on 2-dimensional computed tomographic (CT) scans of hips that underwent Bernese PAO and its role in the surgical decision making. METHODS: This retrospective, case-control study examined and compared preoperative 2-dimensional CT scans of hips that underwent reverse PAO to the hips that underwent traditional PAO. RESULTS: Twelve hips underwent reverse PAO from 2005 to 2010. Twelve hips were randomly selected from a cohort of 52 hips that underwent traditional PAO during same time period. Hips that underwent reverse PAO showed crossover sign on preoperative radiographs, but not on postoperative radiographs. Crossover sign was negative preoperatively and postoperatively on hips that underwent traditional PAO. The 2 groups were similar in regards to preoperative lateral center-edge angle, acetabular index, and anterior center-edge angle on plain radiographs and showed significant improvement after surgery.On preoperative CT scans both acetabulae and femurs were retroverted in reverse PAO group. Comparison of the 2 groups demonstrated that acetabular version (16.5±4.9 degrees vs. 25.3±5.6 degrees, P=0.001), femoral version (12.8±10.4 degrees vs. 31.9±8 degrees, P<0.001), and McKibbins Instability Index (29.3±11.9 degrees vs. 57.1±9.8 degrees, P<0.001) were significantly lower for the reverse PAO than the traditional PAO group. Anterior Acetabular Sector Angle (determines anterior coverage) was significantly higher in reverse PAO group, 53.1±13.7 degrees versus 39.7±10.4 degrees (P=0.013). CONCLUSIONS: Retroverted acetabulae seem to be associated with reduced femoral version. Given that retroverted acetabulum and retroverted femur have additive effect and increase chances of anterior hip pain, preoperative identification of correct acetabular, and femoral version by CT scan or MRI is necessary to determine which hip need reverse PAO as opposed to traditional PAO. LEVEL OF EVIDENCE: Level III-Therapeutic.

Wound Closure in Nonidiopathic Scoliosis: Does Closure Matter?

BACKGROUND: Postoperative wound complications after posterior spinal fusion are difficult to manage. The incidence in the nonidiopathic patient population is significantly higher than the adolescent idiopathic population. A comparison of wound complications after posterior spinal fusion for nonidiopathic scoliosis between the utilization of the orthopaedic surgical team at the time of closure performing a nonstandardized wound closure versus a plastic surgeon with a plastic multilayered closure technique and rotational flap coverage when needed had not previously been evaluated. The purpose of this study was to compare the complication rate between nonstandardized and plastic multilayered closure of the surgical incision in patients undergoing posterior spinal fusion for nonidiopathic scoliosis. METHODS: The charts of 76 patients with a primary diagnosis of scoliosis associated with a syndrome or neuromuscular disease and who underwent a posterior spinal fusion were reviewed. Forty-two patients had their incisions closed using the nonstandardized technique and 34 using the plastic multilayered technique. These 2 groups were compared for age, sex, primary diagnosis, number of levels fused, estimated blood loss, number of units transfused, operating room time, wound complication, and return to operating room. RESULTS: The wound complication rate in the nonstandardized closure group was 19% (8/42) compared with 0% (0/34) in the plastic multilayered closure group (P=0.007). The unanticipated return to the operating room rate was 11.9% (5/42) for the nonstandardized closure patients versus 0% (0/34) for the plastic multilayered closure patients (P=0.061). CONCLUSIONS: The use of the plastic multilayered closure technique in this patient population is important in an effort to decrease postoperative wound complications. The ability of the surgical team to decrease the infection rate of nonidiopathic scoliosis cannot be overstated. The method of wound closure plays a major role in lowering this incidence. LEVEL OF EVIDENCE: Level III-therapeutic.

Current Practice in the Management of Slipped Capital Femoral Epiphysis.

BACKGROUND: The most widely used treatment for slipped capital femoral epiphysis (SCFE) is in situ fixation. In an attempt to reduce the chances of impingement, osteoarthritis, and osteonecrosis, surgeons have started adopting newer surgical techniques. The purpose of this study was to determine the current pattern of treating SCFE. METHODS: A questionnaire was sent electronically to all of the members of the Pediatric Orthopaedic Society of North America. The data were analyzed dividing surgeons into academic versus private practice, years of practice, and number of SCFEs treated per year. RESULTS: Of 990 members, 277 (28%) responded to the survey.Type of practice (academic, n=181 vs. private, n=51): For unstable severe SCFE, surgeons in academic practice use the surgical hip dislocation (SHD) approach significantly more frequently (35.7% vs. 14.9%; P=0.02). A radiolucent table is used significantly more frequently in academic practice for both stable (50.6% vs. 29.8%; P=0.01) and unstable (39.6% vs. 15.2%; P=0.002) SCFE. Fully threaded cannulated screws (44.4% vs. 27.1%; P=0.03), open capsular decompression (63.9% vs. 32.4%; P=0.001), contralateral pinning (79% vs. 58.7%; P=0.005), and postoperative magnetic resonance imaging (MRI) (15.5% vs. 3.9%; P=0.03) are significantly more frequent in academic practice.Years of practice (≤15 y, n=124 vs. >15 y, n=140): For severe stable SCFE, surgeons practicing for ≤15 years do acute osteotomies significantly less frequently (1.8% vs. 9%; P=0.004) and perform SHD significantly more frequently (20.2% vs. 8.2%; P=0.004). For unstable moderate SCFE, SHD is utilized significantly more frequently by surgeons ≤15 years in practice (29.8% vs. 16.5%; P=0.04). Bilateral frog-leg lateral views (86.4% vs. 73.7%; P=0.04), preoperative MRI (36.1% vs. 20.6%; P=0.006), open capsular decompression (69.3% vs. 51.7%; P=0.01) are significantly more frequent among surgeons ≤15 years in practice.Number of SCFE treated per year (<10, n=129 vs. ≥10, n=136): For unstable severe SCFE, surgeons treating ≥10/y perform SHD significantly more frequently (38.6% vs. 26.1%; P=0.02) and do in situ fixation with manual reduction significantly less frequently (11.8% vs. 21.8%; P=0.02). Radiolucent table (54.3% vs. 38%; P=0.01), 7.5 mm screw versus 6.5 mm (62% vs. 45.4%; P=0.01), contralateral pinning (78.9% vs. 67.8%; P=0.04), postoperative MRI (17.6% vs. 9.3%; P=0.04), and postoperative computed tomography (14.7% vs. 7%; 0.04) are significantly more frequent among surgeons doing ≥10/y. Elective implant removal is more common among surgeons treating <10/y (16.2% vs. 6.9%; P=0.02). CONCLUSIONS: Treatment of SCFE varies significantly depending on the surgeon's type of practice, years in practice, and numbers treated per year. Surgeons in academic practice, surgeons with ≤15 years in practice, and surgeons treating greater number of SCFEs are more likely to use SHD to acutely reduce the slip.

Predicting the need for surgical intervention in patients with idiopathic clubfoot.

BACKGROUND: The purpose of this study was to determine the early factors associated with the need for surgical interventions in patients with idiopathic clubfoot treated with the Ponseti method. METHODS: All patients with idiopathic clubfoot treated with Ponseti method at our institution with >3 years of follow-up were evaluated. Age at presentation, history of previous treatment, number of casts used, need for percutaneous Achilles tenotomy (PAT), age of initiation of foot abduction orthosis (FAO), compliance with FAO, and need for additional casts were recorded. Dimeglio/Bensahel and Catterall/Piriani scores were recorded at initial presentation, at initiation of FAO, at 1, 2, 3 years of follow-up, and at the most recent follow-up. RESULTS: Since 2000, 86 patients (134 feet) had >3 years of follow-up from time of initial presentation, and 43 of these feet (32%) had undergone surgery beyond a PAT. Patients who were noncompliant with the FAO were 7.9 times more likely to need surgery than those who were compliant [confidence interval (CI), 2.8-22.0; P<0.001]. Female patients were 5.4 times more likely to need surgery than male patients (CI, 1.8-16.6; P=0.003). For every 1 point increase in Dimeglio/Bensahel score at presentation, patients were 1.3 times more likely to need surgery (CI, 1.0-1.5; P=0.033). For every 1 point increase in Dimeglio/Bensahel score at initiation of the FAO, patients were 1.5 times more likely to need surgery (1.1-2.0, P=0.005). Moreover, for each additional cast required before the initiation of the FAO, patients were 1.5 times less likely to need surgery (CI, 1.1-2.7; P=0.030). No other variable significantly contributed to predicting the need for surgery. CONCLUSIONS: There are early factors that can be used to predict increased risk for surgical intervention in patients undergoing treatment for idiopathic clubfoot. Female patients and those patients with higher Dimeglio/Bensahel scores at presentation and at initiation of the FAO are at increased risk for needing surgical intervention. Noncompliance with the FAO is associated with the highest risk for surgical intervention. LEVEL OF EVIDENCE: Level III.

A radiographic study of pediatric ulnar anatomy.

BACKGROUND: The adult ulna has a unique bony architecture that has been described in the literature, but, to the best of our knowledge, the ulnar anatomy in children has not been described. METHODS: We examined 75 anteroposterior (AP) and 64 lateral radiographs (29 were bilateral) of 50, 0.5- to 11-year-old, healthy children's forearms. On AP radiographs, the total ulnar length, the ulnar proximal angle, the ulnar distal angle, and the distance between each angle from the tip of the triceps insertion; and, on lateral radiographs, the ulnar length and bow deviation were measured. The correlation between age and radiographic measurements, differences based on sex, differences compared with adults' measurements, and interobserver/intraobserver reliability were assessed. RESULTS: Age had a very strong/strong positive correlation with length/distance measurements on both AP and lateral radiographs. Only AP ulnar distal angle was significantly different between sexes (females > males). Compared with the adult ulnar studies, the AP proximal angle in children is significantly smaller and the location of this angle is significantly more distal. Interobserver and intraobserver reliability were very good for length/distance measurements on AP and lateral radiographs. CONCLUSIONS: The knowledge of pediatric ulnar anatomy could be helpful in the treatment of forearm deformities due to multiple hereditary exostosis and osteogenesis imperfecta, and in the treatment of ulnar fractures, particularly in Monteggia variants, where restoration of the correct forearm anatomy is essential to obtain good clinical and functional results. LEVEL OF EVIDENCE: Study of diagnostic test, Level II.

Reliability of the Clinical Measurement of Joint Motion and Muscle Length in the Upper and Lower Extremities of Children with Cerebral Palsy: A Systematic Review.

Reliability of joint motion and muscle length measurement in children with cerebral palsy was examined. Twenty-one studies of intraobserver and/or interobserver reliability were reviewed: joint motion of upper extremities in four and lower extremities in 13; muscle length of upper extremities in one and lower extremities in 15. Intraclass correlation coefficients for goniometric interobserver reliability varied widely for joint motion (range 0.38-0.92) and muscle length (range 0.20-0.95). Inclusion of an error measurement to provide clinicians with a value indicating true change was limited. Further research is required to determine intraobserver and interobserver reliability for these important pediatric clinical measurements.

Achievement of gross motor milestones in children with idiopathic clubfoot treated with the Ponseti method.

BACKGROUND: The Ponseti method of idiopathic clubfoot treatment involves a series of weekly casts, a percutaneous Achilles tenotomy if needed, followed by wearing a foot abduction orthosis (FAO). Gross motor development of children with idiopathic clubfoot has not been examined. The purposes of this study were to determine the ages of achievement of gross motor milestones in children with clubfoot treated with Ponseti method and to compare those ages with historical normative developmental data. METHODS: In this prospective study, 51 children with idiopathic clubfoot who had their first cast applied when ≤90 days old, were full-term with no other orthopaedic conditions or previous clubfoot treatment, and were compliant with wearing FAO were enrolled. Parents were interviewed repeatedly to acquire the ages of achievement of 8 gross motor milestones. RESULTS: Fifteen children were excluded for reasons such as noncompliance with FAO, and not returning for follow-up. Thirty-six children, mean age of 15.2 days at first casting, achieved rolling prone to supine at a mean age of 5.1 months, rolling supine to prone at 5.1 months, sitting without support at 6.6 months, crawling on stomach at 7.1 months, crawling on hands and knees at 8.6 months, pull-to-stand at 9.0 months, cruising at 10.2 months, and ambulating independently at 13.9 months. When compared with previously published values for unaffected children, the mean ages of achievement for 6 of 8 milestones were significantly greater (P<0.05) for the children with clubfoot. The preambulatory milestones were achieved from 0.7 to 1.5 months later and independent ambulation up to 2.2 months later. Fifty percent of children with clubfoot were ambulating at 13.8 months; 90% at 17.7 months. CONCLUSIONS: Minimal delays in gross motor milestone achievement were found in children with idiopathic clubfoot treated with the Ponseti method. Delays were, at most, 1.5 months, except for independent ambulation, which was approximately 2 months. These findings should enable pediatric clinicians to alleviate the concerns of parents of children with idiopathic clubfoot regarding gross motor milestone achievement. LEVEL OF EVIDENCE: Therapeutic Level II.

Opioid Prescription Patterns in Pediatric Orthopedics Following Closed Reduction and Percutaneous Pinning for Supracondylar Humerus Fractures.

BACKGROUND: There is currently an alarming upward trend in the use of prescription opioids in the pediatric population. Previous medical use of prescription opioids has shown to correlate to non-medical use of prescription opioids. To combat this, institutions have started to look at prescribing patterns to understand and eventually standardize a pain protocol to reduce unnecessary analgesics after surgery. Opioids continue to be used widely for postoperative pain control in orthopedic patients. Therefore, this study examined the prescription patterns within a large pediatric orthopedic hospital consortium after closed reduction and percutaneous pinning for supracondylar humerus fractures. METHODS: A retrospective analysis was performed in order to understand the prescribing variability in analgesics for this patient population better. Descriptive statistics and chi-squared analysis were used to evaluate for prescribing patterns. RESULTS: Narcotic medications were prescribed postoperatively to 49.6% of patients. There was no difference in narcotic prescription with length of stay or severity of fracture. Additionally, there were several documented prescribing errors, most commonly by a junior orthopedic resident. CONCLUSIONS: There is significant variability in prescribing patterns among physicians after pediatric supracondylar humerus fractures. Understanding the patterns and implementing a more standardized approach to pain control may help to combat prescribing errors.

Pelvic positioning creates error in CT acetabular measurements.

BACKGROUND: CT allows for accurate measurement of acetabular orientation and shape, but malpositioning of the pelvis may lead to measurement variance. PURPOSE: We therefore sought to determine: (1) whether acetabular anteversion measurements using the femoral head centers differed from those using the posterior ischia, and (2) the extent to which changing obliquity, rotation, and tilt of a pelvis in a CT scanner affected the measurement of acetabular variables. METHODS: A radiopaque human pelvis model with articulated hips was suspended from a plastic sheet as part of an adjustable frame. Changes in the transverse and sagittal planes created rotation and tilt, while rotating the frame in the coronal plane created obliquity. CT scans were obtained, varying the combinations of obliquity, rotation, and tilt by intervals of 5°, up to 20°. Acetabular anteversion (AA), anterior acetabular sector angle (AASA), posterior acetabular sector angle (PASA), and horizontal acetabular sector angle (HASA) were measured. RESULTS: The two methods for measuring AA yielded values differing by 1° to 4° but correlated (r = 0.981) across the spectrum of pelvis positioning. Pelvic obliquity and tilt were linearly associated with changes in the measurements. For each 1°-increase in pelvic obliquity, AA changed -0.4°, and AASA, PASA, and HASA changed 1.93°, 0.99°, and 2.80°, respectively. For each 1°-increase in pelvic tilt, AA changed 0.8°, and AASA, PASA, and HASA changed -1.07°, 0.52°, and -0.51°, respectively. Rotation had no affect on the variables. CONCLUSIONS: Small changes in pelvic obliquity and tilt were associated with variances in acetabular measurements. The measured changes were directly proportional to the changes in obliquity and tilt, and were additive. Pelvic rotation created no changes in measurement.

Clubfoot classification: correlation with Ponseti cast treatment.

BACKGROUND: Many different clubfoot classification systems have been proposed, but no single one is universally accepted. Two frequently cited systems, developed by Dimeglio/Bensahel and Catterall/Pirani, are often used for evaluation purposes in the treatment of idiopathic clubfoot. Our hypothesis was that the initial scores would be positively correlated with the number of casts required for clubfoot correction, indicating to us that the more severe score would require more casts, and therefore truly show the accuracy and usefulness of the scoring system. METHODS: From May 2000 to April 2008, 123 patients (185 feet) with idiopathic clubfeet were treated. All patients were below 60 days of age (mean 15.3 d, range: 2 to 57 d) at the time of their initial evaluation, and had not received prior clubfoot treatment. All cast placements were under the supervision of the same pediatric orthopedic surgeon. Initial correction was achieved in all patients. RESULTS: The mean number of casts required for correction was 5.1 (range: 2 to 8). On the basis of number of casts required, no significant differences were found in final total scores (Dimeglio/Bensahel P=0.14 and Catterall/Pirani P=0.44), indicating a similar level of correction for all feet. The Dimeglio/Bensahel and Catterall/Pirani classification systems were both similarly, poorly correlated with the number of casts needed [Spearman rank correlation coefficients (rs)=0.34 vs. 0.33]. The 2 components with the highest correlations were equinus (rs=0.39) and forefoot adduction (rs=0.35) for the Dimeglio/Bensahel system and coverage of the lateral head of the talus (rs=0.40) and rigid equinus (rs=0.39) for the Catterall/Pirani system. CONCLUSIONS: When using the initial scores, both the Dimeglio/Bensahel and Catterall/Pirani classification systems had a low correlation with the number of Ponseti casts required. Analysis of the individual components revealed variability in the coefficients, with some having low-to-moderate correlation and others having none. There was no difference between the Dimeglio/Bensahel and Catterall/Pirani classification systems when measuring their correlation with the number of Ponseti casts required for clubfoot correction. An improved classification system is needed to predict the length of treatment and, ultimately, the risk of recurrence. LEVEL OF EVIDENCE: Prognostic Level IV.

Correction of arthrogrypotic clubfoot with a modified Ponseti technique.

Surgical releases for arthrogrypotic clubfeet have high recurrence rates, require further surgery, and result in short, painful feet. We asked whether a modified Ponseti technique could achieve plantigrade, braceable feet. Ten patients (mean age, 16.2 months; range, 3-40 months), with 19 arthrogrypotic clubfeet, underwent an initial percutaneous Achilles tenotomy to unlock the calcaneus from the posterior tibia followed by weekly Ponseti-style casts. A second percutaneous Achilles tenotomy was performed in 53%. Mean number of casts was 7.7 (range, 4-12). From pretreatment to completion of initial series of casts, mean scores of Dimeglio et al. improved from 16 to 5 (ranges, 12-18 and 2-9, respectively), Catterall scores (as modified by Pirani and colleagues) from 4.8 to 0.9 (ranges, 1.5-6.0 and 0.0-2.0), and maximum passive dorsiflexion from -45 degrees (range, -75 degrees to -20 degrees ) to 10 degrees (range, 0 degrees to 40 degrees ). Ankle-foot orthoses maintained correction. At the minimum followup of 13 months (mean, 38.5 months; range, 13-70 months), the mean maximum dorsiflexion was 5 degrees (range, -20 degrees to 20 degrees ), two patients had posterior releases and no patient's ambulatory ability was compromised by foot shape. Arthrogrypotic clubfeet can be corrected without extensive surgery during infancy or early childhood. Limited surgery may be required as the children age.

Articulated hip distraction: a treatment option for femoral head avascular necrosis in adolescence.

PURPOSE: To describe the clinical outcomes of adolescent patients treated with articulated hip distraction (AHD) for avascular necrosis (AVN) of the femoral head. Outcomes were examined in order to better understand the usefulness of and indications for performing hip arthrodiastasis in this patient population. METHODS: : Retrospective review was performed on 31 hips with femoral head AVN treated with AHD. Mean age at treatment was 14.7 years. Preoperative and follow-up pain and physical limitations, as well as follow-up range of motion, were assessed. RESULTS: Follow-up assessment was obtained at 18.7 years. Time of follow-up was 57.4 months after distraction. The etiologies of AVN were the following: 10 slipped capital femoral epiphysis (SCFE), 5 idiopathic AVN, 3 with hip dysplasia, and 12 others. There was a significant difference in pain preoperatively and postoperatively (P<0.001), most patients (78.6%, n=22) had less pain after the treatment. Multivariate regression model demonstrated that patients with SCFE were likely to have less improvement in pain than patients with other etiologies (odds ratio, 22.7; P=0.035). All patients had activity limitations before the treatment; at the postoperative assessment, half of our patients (n=14) reported no limitations in their regular daily activities. Eight patients had minor complications with the fixator. At follow-up, 5 patients (17.2%) converted to total hip replacement or arthrodesis. Survival rates were 90.6% at 5 years, 77.7% at 10 years, and 38.8% at 15 years. CONCLUSIONS: Hip distraction arthroplasty in adolescent patients with symptomatic AVN reduces the amount of pain and limitation in daily activities at a follow-up of 4.7 years. Arthrodiastasis is not the final solution to AVN. With longer follow-up, patient's symptoms increases. Patients with AVN secondary to SCFE do not seem to benefit from this procedure as much as other patients do. Articulated hip distraction is a safe and appropriate procedure to perform in these patients. The procedure might be able to delay definitive surgical procedures at an early age, restoring function and improving the patient's quality of life.

Femoral deformity correction in children and young adults using Taylor Spatial Frame.

UNLABELLED: The Taylor spatial frame (TSF) has been used commonly in children and young adults. Its use in the tibia is more extensively studied and applied than in the femur. We asked whether normal alignment can be achieved with accuracy during correction of femoral deformities while avoiding major complications in children and young adults. We retrospectively reviewed the clinical and radiographic records of 20 patients (22 limbs), ages 5.9 to 24.6 years, who underwent a TSF for femoral deformity. Etiology included a number of diagnoses of the pediatric age. Minimum followup was 4.5 months (mean, 15.7 months; range, 4.5-35 months). The mean time in frame was 6.2 months (range, 2.6-19 months). Frontal and sagittal plane deformities were corrected to within normal values. A mean limb lengthening of 4.9 cm (range, 1.5-9 cm) was performed in eight femora in seven of which the limb length discrepancy was a secondary concern. External fixation index in the lengthening subgroup was 2.2 months/cm. The 15 complications in 13 limbs included pin tract infection, knee stiffness, delayed union, skin irritation, and posterior knee subluxation. No complications occurred in nine limbs. Computer-assisted femoral deformity correction with six-axis deformity analysis and the TSF is an accurate and safe technique in children and young adults. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Functional outcome in adult patients following Bernese periacetabular osteotomy.

This study evaluated functional outcome following Bernese periacetabular osteotomy. In 24 patients with mean follow-up of 3.5 years, mean dysfunction score was 15.23 on the Short Musculoskeletal Function Assessment. Eighteen patients (75%) scored = or <20, indicating a high functional level. Irrespective of preoperative Shenton line continuity, most patients demonstrated a high functional level. However, a trend toward a poorer outcome was observed in patients with preoperative noncongruent joints and Tonnis osteoarthritis grade 3. These results suggest patients with less than optimal presentation may still benefit from this surgery, delaying or eliminating the need for total hip arthroplasty.
