- Abstract
Background: Developmental hip dysplasia (DDH) is a common condition associated with pain, disability and early hip osteoarthritis when untreated. Health utility scores have not previously been defined for a comprehensive set of DDH health states. The purpose of this study was to establish utility scores associated with DDH health states., Methods: Patients treated for DDH using either Pavlik harness or abduction bracing and closed/open hip reduction between February 2016 and March 2023 were identified. Thirteen vignettes describing health states in the DDH life cycle were developed. Parents of patients were asked to score each state from 0 to 100 using the feeling thermometer. A score of "0" represents the worst state imaginable/death and a score of "100" represents perfect health. Utility scores were calculated and compared between parents of patients treated operatively and nonoperatively., Results: Ninety parents of children with DDH (45 operative, 45 nonoperative) were enrolled. There were 82 (91.1%) female children (median age of 4.9 years at enrollment). Median utility scores ranged from 77.5 [interquartile range (IQR): 70.0 to 90.0] for Pavlik harness and 80.0 (IQR: 60.0 to 86.3) for abduction bracing to 40.0 (IQR: 20.0 to 60.0) for reduction/spica cast and 40.0 (IQR: 20.0 to 50.0) for end-stage hip arthritis. Utility scores were lower in the operative group for Pavlik harness (median 70.0 vs. 80.0, P<0.01), end-stage arthritis (30.0 vs. 40.0, P=0.04), and 1 year after total hip arthroplasty (85.0 vs. 90.0, P=0.03) health states compared with the nonoperative group. There were no differences in other scores., Conclusions: Thirteen health states related to the life cycle of DDH were collected. Nonoperative interventions for DDH were viewed by parents slightly more favorably than operative treatments or long-term sequelae of untreated DDH. Future studies can assess other potential treatment experiences for patients with DDH or use these scores to perform cost-effectiveness analysis of different screening techniques for DDH., Level of Evidence: Level III., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Background: Supracondylar humerus (SCH) fractures are common pediatric injuries, typically requiring closed reduction and percutaneous pinning or open reduction. These injuries are managed frequently by both pediatric-trained (PTOS) and nonpediatric-trained (NTOS) orthopaedic surgeons. However, some literature suggests that complications for pediatric injuries are lower when managed by PTOS. Therefore, this meta-analysis sought to compile existing literature comparing patients treated by PTOS and NTOS to better understand differences in management and clinical outcomes., Methods: Using preferred reporting items for systematic reviews and meta-analyses (PRISMA) methodology, a systematic review was conducted for all articles comparing SCH fractures managed by PTOS and NTOS in 4 online databases (PubMed, Embase, CINAHL, Cochrane). Study quality was assessed through the use of the Newcastle-Ottawa Scale. Meta-analyses were then performed for postoperative outcomes using pooled data from the included studies. Statistics were reported as odds ratios and 95% CI., Results: This search strategy yielded 242 unique titles, of which 12 underwent full-text review and 7 met final inclusion. All studies were retrospective and evaluated patients treated in the United States. There were a total of 692 and 769 patients treated by PTOS and NTOS, respectively. PTOS had shorter operative times [mean difference, 13.6 min (CI, -23.9 to -3.4), P=0.01] and less frequently utilized a medial-entry pin [odds ratios, 0.36 (CI, 0.2 to 0.9), P=0.03]. There were no differences in time to treatment, the necessity of open reduction, postoperative Baumann angle, or complications including surgical site infection or iatrogenic nerve injury., Conclusions: Despite shorter operative times and lower frequency of cross-pinning when treated by PTOS, pediatric SCH fracture outcomes are similar when treated by PTOS and NTOS. These findings demonstrate that these fractures may possibly be treated safely by both PTOS and experienced fellowship-trained academic NTOS who are comfortable managing these injuries in pediatric patients., Level of Evidence: Level III; Meta-analysis., Competing Interests: P.D.F.: Clinical Orthopaedics and Related Research: Editorial or Governing board.

- Abstract
Study Design: Cross-sectional survey., Objective: To determine the prevalence of back pain in American children and adolescents, with a focus on anatomic region, duration, severity, and treatment patterns, and to investigate for any predictive variables., Summary of Background Data: No study has examined the prevalence of back pain in American children and adolescents in the last 15 years. Because the prevalence of back pain varies greatly by country and year of investigation, previous studies are not generalizable., Methods: A United States epidemiologic cross-sectional survey-based investigation was performed in children and adolescents ages 10 and 18 years old, equally split by age and sex, and representing census-weighted distributions of state of residence, race/ethnicity, and health insurance status. Prevalence of back pain was evaluated and described., Results: In total, 1236 (33.7%) participants reported experiencing back pain within the last year and 325 (8.9%) reported severe back pain within the last year. Prevalence of back pain increased with age and was significantly more common in females, P < 0.001 for both. Treatment for back pain was sought by 505 (40.9%) of the participants with pain, of which physical therapy was the most common. Invasive procedural treatment (e.g., injections, surgery) were rare and comprised only 61 (1.6%) of study participants. In addition, government insurance and lack of insurance coverage was associated with low treatment seeking behavior compared to private insurance users (P = 0.010 and P = 0.006, respectively)., Conclusion: Despite how commonly it presents, the majority of young patients with back pain do not report procedural treatment such as injections or surgery. However, because many American children and adolescents seek treatment, future research on the etiology, treatment, and prevention of back pain in children and adolescents is essential to reducing a common and financially demanding problem., Level of Evidence: 4.

- Abstract
Background: The randomized controlled trial (RCT) is the gold standard study design allowing critical comparison of clinical outcomes while minimizing bias. Traditionally clinical trials are evaluated through statistical significance, expressed by P-values and confidence intervals. However, until recently, the robustness of a study's conclusions has been given little attention. A new metric, the fragility index, quantifies the number of patients theoretically required to switch outcomes in order to reverse the study conclusions. The primary aim of our work was to determine the fragility index of RCTs in the pediatric orthopaedic literature. The secondary aim was to determine study factors associated with lower fragility index., Methods: Pubmed and Embase were systematically searched for pediatric orthopaedic RCTs published September 1, 2006 to September 1, 2016. Two independent reviewers screened titles, abstracts, and manuscripts to identify studies published in English involving 2 treatment arms. Trials without dichotomous primary or secondary outcomes or with patients >18 years were excluded. Data were extracted from each eligible article in duplicate and the fragility index was determined using Fisher exact test, with previously published methods. Univariate analysis was used to determine factors associated with lower fragility index., Results: Seventeen trials were eligible for inclusion. The median treatment arm size was 58 and overall sample size was 116 patients. The median fragility index was 3 (range, 0 to 18). A fragility index of 3 means that just 3 patients would need to switch treatment outcomes in order for the trial results to become statistically nonsignificant. In 1 study, the number of patients lost to follow-up exceeded the fragility index, such that the study conclusions could be completely reversed purely depending on the outcomes of the patients lost to follow-up. Lower fragility index was associated with smaller patient sample sizes and greater P-values., Conclusions: The fragility index is a useful adjunct metric to the P-value and confidence intervals, allowing analysis of the robustness of study conclusions. RCTs in pediatric orthopaedics often have small sample sizes, many with low fragility indices. Future efforts could focus on encouraging institutional collaboration and patient recruitment with the ultimate goal of improving RCT sample sizes, and potentially improving the robustness of RCT results., Level of Evidence: Level I.

- Abstract
Background: Clubfoot is a common congenital anomaly with multiple potential risk factors. Identification of modifiable risk factors may minimize future incidence of clubfoot. The aim of this meta-analysis was to systematically review and analyze the best clinical evidence regarding risk factors associated with clubfoot., Methods: Medline, Embase, and Cochrane databases were systematically searched from 1967 to May 11, 2016 for studies reporting risk factors for clubfoot. Randomized trials and observational studies were eligible for inclusion, and assessed in duplicate. Study quality was assessed with the Newcastle-Ottawa Scale or Cochrane risk of bias tool; low quality studies were excluded, all randomized trials were included. Two reviewers extracted data independently. This meta-analysis was conducted in accordance with PRISMA guidelines. Pooled effect estimates for the odds of clubfoot were calculated using random or fixed-effects models based on heterogeneity., Results: Forty-two studies (28 case-control, 10 cohort, 4 randomized trials) comprising 31,844 clubfoot cases and 6,604,013 controls were included. Risk factors associated with increased odds of clubfoot included maternal smoking [odds ratio (OR)=1.65; 95% confidence interval (CI), 1.54-1.78], paternal smoking (OR=1.72; 95% CI, 1.05-2.84), maternal body mass index >30 (OR=1.46; 95% CI, 1.29-1.65), family history (OR=7.80; 95% CI, 4.04-15.04), amniocentesis (OR=2.08; 95% CI, 1.34-3.21), selective serotonin reuptake inhibitor exposure (OR=1.78; 95% CI, 1.34-2.37) maternal single status (OR=1.17; 95% CI, 1.11-1.23), gestational diabetes (OR=1.40; 95% CI, 1.13-1.72), nulliparity (OR=1.32; 95% CI, 1.19-1.45), male sex (OR=1.68; 95% CI, 1.48-1.94), and aboriginal Australian race (OR=2.35; 95% CI, 1.63-3.38)., Conclusions: Smoking, maternal obesity, family history, amniocentesis, and some selective serotonin reuptake inhibitor exposures are the most clinically relevant exposures associated with increased odds of clubfoot, with family history representing the greatest risk. Recognition of modifiable risk factors may help in counseling patients, and minimizing clubfoot incidence., Level of Evidence: Level II.

- Abstract
Background: Radiographic assessment of skeletal age in pediatric patients is a common practice among orthopaedic surgeons. Current methods of assessment remain labor intensive and require special resources. This study sought to investigate a novel, abridged method of bone age assessment that may serve as a simpler and more efficient alternative to the current standard., Methods: A shorthand bone age (SBA) method developed at our institution was compared against the Greulich and Pyle method from which it was derived. Standard left hand bone age radiographs of 140 male and 120 female patients, previously assigned skeletal ages ranging from 12.5 to 16 years in males and 10 to 16 years in females by musculoskeletal radiologists using the Greulich and Pyle radiographic atlas, were read using the shorthand method by 3 attending pediatric orthopaedic surgeons and an orthopaedic surgery resident. The shorthand method utilizes a single, univariable criterion for each age, rather than a multivariable subjective comparison to a radiographic atlas. All reviewers were blinded to the original bone age determination. Interobserver reliability, intraobserver reliability, and agreement with the previous records utilizing the atlas were calculated using weighted κ., Results: The SBA method readings demonstrated substantial agreement with readings by the Greulich and Pyle atlas, demonstrating weighted κ values ranging from 0.71 to 0.75. The SBA method also demonstrated substantial to almost perfect interobserver and intraobserver reliability, with values ranging from 0.77 to 0.87 and from 0.87 to 0.95, respectively., Conclusions: These results are comparable or superior to previous reports which investigate the validity and reliability of other skeletal age assessment tools. The SBA assessment tool offers a simple and efficient alternative to current methods., Level of Evidence: Diagnostic study, level III.

- Abstract
Background: The recent emphasis on shared decision-making has increased the role of the Internet as a readily accessible medical reference source for patients and families. However, the lack of professional review creates concern over the quality, accuracy, and readability of medical information available to patients on the Internet., Methods: Three Internet search engines (Google, Yahoo, and Bing) were evaluated prospectively using 3 difference search terms of varying sophistication ("congenital hip dislocation," "developmental dysplasia of the hip," and "hip dysplasia in children"). Sixty-three unique Web sites were evaluated by each of 3 surgeons (2 fellowship-trained pediatric orthopaedic attendings and 1 orthopaedic chief resident) for quality and accuracy using a set of scoring criteria based on the AAOS/POSNA patient education Web site. The readability (literacy grade level) of each Web site was assessed using the Fleisch-Kincaid score., Results: There were significant differences noted in quality, accuracy, and readability of information depending on the search term used. The search term "developmental dysplasia of the hip" provided higher quality and accuracy compared with the search term "congenital hip dislocation." Of the 63 total Web sites, 1 (1.6%) was below the sixth grade reading level recommended by the NIH for health education materials and 8 (12.7%) Web sites were below the average American reading level (eighth grade)., Conclusions: The quality and accuracy of information available on the Internet regarding developmental hip dysplasia significantly varied with the search term used. Patients seeking information about DDH on the Internet may not understand the materials found because nearly all of the Web sites are written at a level above that recommended for publically distributed health information., Clinical Relevance: Physicians should advise their patients to search for information using the term "developmental dysplasia of the hip" or, better yet, should refer patients to Web sites that they have personally reviewed for content and clarity. Orthopaedic surgeons, professional societies, and search engines should undertake efforts to ensure that patients have access to information about DDH that is both accurate and easily understandable.

- Abstract
Thirteen patients (18 hips) with cerebral palsy and painful hip subluxation or dislocation underwent proximal femoral resection-interposition arthroplasty (PFRIA) as a salvage procedure for intractable pain or seating difficulty. Eleven patients (14 hips) had a prior failed soft-tissue or bony reconstruction. The average age at surgery was 26.6 years (range, 10.7-45.5 years), and average follow-up was 7.4 years (range, 2.2-20.8 years). All patients/caregivers noted significant improvement in subjective assessment of pain after the surgery. Upright sitting tolerance improved from an average preoperative value of 3.2-8.9 h postoperatively (p < 0.01). Four patients who were unable even to sit in a customized wheelchair before the operation could be easily seated in a custom chair after surgery. Hip range of motion including flexion, extension, and abduction was significantly improved postoperatively (p < 0.05). Single-dose radiation therapy was used postoperatively for five hips and resulted in a significantly lower grade of heterotopic ossification at final follow-up (p < 0.005). Skeletal traction in the postoperative period did not prevent proximal migration of the femur compared with skin traction. Maximal pain relief was achieved at an average of 5.6 months postoperatively (range, 0.03-14 months). Complications included transient postoperative decubitus ulceration (four patients), pneumonia (two patients), and symptomatic heterotopic bone (two patients). The significant improvements in pain management, sitting tolerance, and range of motion suggest that PFRIA is a reasonable salvage procedure for the painful, dislocated hip in cerebral palsy. Resolution of pain may not be immediate, as was noted in this series.

- Abstract
Talonavicular coalition is reported as an asymptomatic congenital anomaly of the foot that is noticed incidentally on radiographs of the foot, and is often associated with symphalangism, clinodactyly, ball-and-socket ankle joint, a great toe that is shorter than the second toe, and an autosomal dominant inheritance pattern. We describe here three patients with five involved feet. All three patients had chronic foot pain not secondary to trauma, and all five feet required treatment to alleviate the pain.

- Abstract
The transport of 222Rn from soil, through a vented crawl space, and into the living space of single-family residences was studied. Two houses were monitored in detail for periods of 5 and 7 weeks. With crawl space vents open, the average indoor 222Rn concentrations were 1.2 and 0.6 pCi 1.-1 (44 and 22 Bq m-3); with the vents sealed the averages rose to 2.2 and 1.0 pCi 1.-1 (81 and 37 Bq m-3). The data suggest that, of the Rn released into the crawl space from the soil beneath the house, a significant fraction, perhaps 50% or more, enters the living space. The effect of 3 meteorological parameters--wind speed, indoor-outdoor temperature difference, and rate of barometric pressure change--on Rn concentration and entry rate were examined. In 1 of the houses a higher temperature difference corresponded to a higher indoor concentration, suggesting that the increased infiltration rate is more than compensated by an increase in the Rn entry rate. On the other hand, a high wind speed tended to reduce the indoor concentration, presumably by increasing both cross-ventilation of the crawl space and the infiltration rate of the living space. Results suggest that Rn transport into the crawl space of at least 1 of the houses occurred by pressure-driven flow, rather than solely by molecular diffusion. The diffusion coefficient of 222Rn through polyethylene sheeting, such as was present on the ground beneath this house, was measured in the laboratory and found to range from 0.65 X 10(-7) cm2 s-1 at 11 degrees C to 1.6 X 10(-7) cm2 s-1 at 25 degrees C, implying that the maximum diffusive flux through the sheet was many times smaller than that necessary to account for the rate of Rn entry into the house. A third house was studied using a tracer gas injected into the crawl space at a controlled rate. The fraction of air leaving the crawl space that entered the living space ranged from 0.3 to 0.65, in good agreement with results for Rn transmission in the other 2 houses, assuming that the 222Rn flux into the crawl space was comparable to that which would have resulted from molecular diffusion from soil having a 222Rn diffusion length of 1.0 m. By sealing leaks in the floor of this house, the average infiltration rate was reduced by 25%, but the indoor concentration of the tracer gas remained constant.

- Abstract
Indoor Rn concentrations, measured in 58 houses during a 4- to 5-mon period during the winter and spring of 1981-1982, varied from 0.1-16 pCi l-1 (4-590 Bq m-3). Average infiltration rates were determined for each house during the same period, based on a measurement of the effective leakage area and an infiltration model, and found to range from 0.2-2.2 air changes per hour (h-1). Indoor Rn concentrations correlated poorly with infiltration rates for houses within each city as well as for the entire sample. Differences in Rn entry rates among houses thus appear to be more important than differences in infiltration rates in determining whether a house has high indoor Rn levels, consistent with previous indications from grab-sample measurements. Radon entry rates and indoor Rn concentrations were generally higher in houses in Fargo, ND, and Colorado Springs, CO, than in houses in Portland, ME, and Charleston, NC.

- Abstract
Using a long-term-average, single-cell model and available data for U.S. housing, the concentration of 222Rn in indoor air due to the use of potable water is assessed. The ratio of the airborne 222Rn concentration to the concentration in water is represented by a lognormal distribution with geometric mean and geometric standard deviation of 0.65 X 10(-4) and 2.88, respectively, in fair agreement with the previously reported results of direct measurements of the ratio in 13 houses. By combining this result with data on 222Rn concentrations in U.S. water supplies, potable water is estimated to contribute an average of 24, 1.3, and 0.1 Bq m-3 to the airborne 222Rn concentration in residences served by private wells, public ground water, and surface water supplies, respectively.
