As no prior study has examined the citations profile of key articles related to periacetabular osteotomy (PAO), our analysis utilized the Web of Science database to (1) identify the most-cited clinical studies relating to PAO in the management of acetabular dysplasia and (2) assess any trends over time with respect to the quality of literature. The top 100 highest-cited studies related to PAO had a mean of 49 citations (range, 6–666 per study). With respect to the level of evidence, most studies had level IV evidence (58%); 1% level I, 16% level II, 28% level III and 2% level V. Most studies were retrospective (n = 86); there were 14 prospective studies (including one randomized study). The most common study designs were case series (n = 58) and cohort (n = 16), followed by matched-cohort (n = 13) and case–control (n = 6). The mean ± SD Newcastle-Ottawa Scale score was 6.48 ± 1.31. A total of 59 and 41 of the included articles were classified as high risk and high quality, respectively. No studies were classified as very high risk. As a whole, our analysis demonstrated that currently available PAO literature is still of low quality and of low level of evidence. While PAO has been well-documented as a durable procedure for addressing acetabular dysplasia, future research must focus on higher quality, randomized and prospective data to answer key clinical or technique-related topics.

YouTube is an increasingly accessible platform for families to obtain health information from; however, it is unregulated. The aim of this article was to assess the quality, reliability and accuracy of YouTube videos related to three common pediatric hip conditions: development dysplasia of the hip (DDH), slipped capital femoral epiphysis (SCFE) and Legg-Calve-Perthes disease. YouTube was searched using a variety of keyword combinations. Videos were analysed using Journal of the American Medical Association, Global Quality Score and condition-specific scores created specifically for this study. Video duration and the number of views were also recorded. In total 120 videos were analysed, 40 for each of DDH, SCFE and Perthes disease. YouTube videos from physicians and academic institutions/hospitals are of significantly higher quality, reliability and accuracy than videos from patients, nonphysicians and commercial outlets. The higher quality for physician videos is associated with significantly longer video. Differences between the three pediatric orthopaedic conditions were not statistically significant. Videos of higher quality may be used as an adjunctive tool to strengthen clinical consultation. Parents and caregivers should be guided to videos from academic institutions or hospitals as a way of improving health literacy.

The purpose of this study was to examine whether measurement accuracy is impacted with a low radiation radiograph technique. Treatment decisions for hip dysplasia require serial radiographs to monitor acetabular anatomy. However, radiation use creates concern for future malignancy. Standard radiograph technique utilizes a grid to enhance clarity, but requires a larger X-ray dose. We hypothesized grid removal would lower radiation exposure without decreasing measurement accuracy. This is a retrospective cohort study of patients with idiopathic DDH and neuromuscular hip displacement at a single institution from 2019 to 2020 receiving surveillance radiographs. A cohort receiving modified technique radiographs (grid removed) was compared to an age-matched cohort receiving standard technique radiographs. Four examiners measured radiographs on two separate occasions, a minimum of 2 weeks apart. Migration percentage (MP) was measured for neuromuscular patients and acetabular index (AI) for idiopathic DDH. Intraclass correlation coefficient (ICC) with a 95% confidence interval (CI) was used to evaluate inter-observer and intra-observer agreement for measurements. Average radiation dose for both techniques. A total of 134 age-matched patients were included for measurement of MP. Thirty age-matched patients were included for AI measurements. Inter and intra-rater reliability of MP and AI were not different with or without use of the grid. There was a 50–75% decrease in radiation dose per radiograph following grid removal, dependent on patient size. The adjusted radiograph technique showed no significant difference in MP or AI reliability. A slight decrease in picture contrast did not jeopardize measurement reliability and decreased radiation exposure for the patient significantly. This simple technique can be useful for patients requiring multiple radiographs over time.

Normal anatomical variants and pathological deformities of the pediatric hip can only be differentiated after a prior definition of normal ranges for anthropometric parameters with increasing age. Aim of the present study was to provide reliable reference values of the pediatric hip morphometry, using computed tomography (CT)-based rotation-corrected summation images of the pelvis that simulate the widely available plain radiograph-based measurements, but offer the higher precision of the CT technique. This retrospective study included 85 patients (170 hips) under 15 years of age (0–15). The measured anthropometric parameters included femur head extrusion index, lateral center-edge angle, acetabular inclination, Tönnis angle, and femoral neck-shaft angle. Mean values, range, SD, P values, intra-rater, and inter-rater reliability were calculated. All measurements correlated with age. None of the measurements correlated with gender or side. Rapid growth phases were noted in all measurements at the age of 12 (14 in males and 11 in females). The inter-rater and intra-rater reliability was high (range inter/intraclass correlation coefficient 0.926–0.998 Cronbach’s alpha 0.986–0.998). The present work provides age- and gender-related normative values of the classically used hip measurements as well as growth phases describing pediatric hip morphology in a broad age range. A discrepancy was noted between the values measured in the current study and the classical X-ray-based reference values in the literature especially for the Tönnis angle and LCEA values. This suggests that the rotation and inclination correction in the CT-based techniques might have the advantage of compensating for a possible overestimation in the conventional X-ray-based methods.

We present the case of three pediatric patients who presented with non-fracture acute lateral compartment syndrome after 'minor trauma'. All patients were male and sustained the inciting event during football. Two of the patients were able to resume play after their injury. All patients sustained intramuscular proximal avulsion ruptures of the peroneus longus muscle. At final follow-up, all but one patient had documented full neurologic recovery. A seemingly innocuous event may cause acute compartment syndrome in the adolescent male. Compartment syndrome in the absence of fracture should be promptly recognized to prevent delay in surgical treatment.

The purpose of this study is to state the reliability of neonatal hip ultrasound interpretation, defining the intra and interoperator variability in the evaluation of the scans. We considered a sample of 2071 scans (coming from 798 patients who attended the screening programme for hip dysplasia), which were interpreted by the operator who obtained and read the images at the screening time and then by a different operator who saw the images for the first time. Both the intra and interoperator variability of α and β angles’ values resulted statistically not significative (intraclass correlation coefficient > 0.8) and determining a class shift (according to the Graf’s classification) in a nonstatistically significative number of cases (agreement percentage >91% and Cohen’s κ >0.8). Hip sonography can reliably detect hip dysplasia and the intra and interoperator variability in the interpretation of the exam is NS when the examination is correctly executed.

Shelf acetabuloplasty continues to be effective in the prevention or delay of osteoarthritis in adolescent dysplastic hips. We aimed to evaluate the efficacy and to determine the correct level of the bone graft objectively. We retrospectively analyzed 16 hips underwent Shelf acetabuloplasty originated by Spitzy. The mean age at surgery was 15.3 years old with the mean caput index at 39.7%. The average follow-up was 11 years. The radiological evaluation was based on acetabular-head index (AHI) at preoperative and latest radiographs, acetabular-Shelf distance (ASD) and Shelf-head ratio at immediate postoperative and latest radiographs. The cutoff value for the ideal ASD was determined by receiver operating characteristic (ROC) and the Pearson correlation test used in statistical analysis to assess the relationship between ASD and Shelf graft resorption. Clinical evaluation was performed using Harris Hip Score (HHS) at the latest follow-up. The AHI was improved in all cases, from mean 56.9 to 91.0% (P < 0.001). The mean of ASD was 7 mm. In nine of the 16 cases, the Shelf graft was well united at the same level of the existing acetabulum with good continuity. The ROC curve showed the cutoff value for the ideal ASD was 6 mm. The Pearson correlation test also showed a positive relationship between ASD and Shelf graft resorption (P = 0.001). The average of HHS scores was 98.1 points. Both radiological and clinical results were acceptable. The ideal placement that keeps the shelf sufficient to bear the mechanical stress without bone resorption over time was at the level of 6 mm from the joint space. Level III – therapeutic study.

The aim of the study is to assess the safety and efficacy of Imhäuser osteotomy combined with osteochondroplasty in the treatment of moderate-severe stable slipped capital femoral epiphysis (SCFE) on short-term basis. Nineteen patients (20 hips) with moderate-severe stable SCFE were surgically treated by Imhäuser osteotomy combined with osteochondroplasty and followed up for 3–4 years. The cases aged between 12 and 18 years at the time of surgery and complained of a variety of symptoms and signs that included pain, limping, limited range of motion (ROM), and/or abductor weakness. The outcomes were assessed using clinical and radiological parameters as well as functional outcome measures: “Harris hip score” (HHS) and “The Western Ontario and McMaster Universities Osteoarthritis Index” (WOMAC). There were statistically significant improvements in flexion, internal rotation, and abduction ROM. HHS and WOMAC improved significantly with final follow-up scores at 86.76 and 6.4%, respectively. The radiological parameters showed significant improvement regarding Southwick angle (mean 12.8°), alpha angle of Nötzli (mean 29.85°), Hilgenreiner epiphyseal angle (mean 37.65°), neck shaft angle (mean 140.63°), and acetabulo-trochanteric distance (median14.1 mm) at the end of follow-up period. Imhäuser osteotomy combined with osteochondroplasty is a good option in moderate-severe stable SCFE treatment.

The cases aged between 12 and 18 years at the time of surgery and complained of a variety of symptoms and signs that included pain, limping, limited range of motion (ROM), and/or abductor weakness. The outcomes were assessed using clinical and radiological parameters as well as functional outcome measures: “Harris hip score” (HHS) and “The Western Ontario and McMaster Universities Osteoarthritis Index” (WOMAC). There were statistically significant improvements in flexion, internal rotation, and abduction ROM. HHS and WOMAC improved significantly with final follow-up scores at 86.76 and 6.4%, respectively. The radiological parameters showed significant improvement regarding Southwick angle (mean 12.8°), alpha angle of Nötzli (mean 29.85°), Hilgenreiner epiphyseal angle (mean 37.65°), neck shaft angle (mean 140.63°), and acetabulo-trochanteric distance (median14.1 mm) at the end of follow-up period. Imhäuser osteotomy combined with osteochondroplasty is a good option in moderate-severe stable SCFE treatment.","PeriodicalId":16709,"journal":{"name":"Journal of Pediatric Orthopaedics B","volume":"17 1","pages":"283 - 291"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77862588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variation exists in the peak presentation of slipped capital femoral epiphysis (SCFE). The objective of this study was to compare two cohorts of children (South Africa and the UK) and explore similarities and differences regarding demographic and epidemiological features, incidence and seasonal variation in peak presentation. Patients presenting with SCFE at one of two hospitals were included in the study. A retrospective cohort was collected from hospital records. The following factors were recorded: duration of symptoms, chronicity, stability, seasonality, severity and prophylactic pinning. A total of 137 patients were included in the study – 70 patients (80 hips) from South Africa and 67 patients (73 hips) from the UK. Both sites recorded more than 50% incidence of a chronic slip. There was higher delay to presentation in the UK compared with South Africa (90 vs 60 days, P = 0.0262). The UK population were more skeletally mature (32.8% open triradiate cartilage) compared with the South Africa population (64.9% open triradiate cartilage). In both populations, the most common season of symptom onset was summer. In the UK, the most common season of symptom presentation was in autumn compared with summer in South Africa. This study found significant differences in the two countries, including a more skeletally mature population in the UK. Both cohorts showed seasonal variation in peak incidence, but there was more seasonal variation in peak incidence in the UK – in the summer for onset of symptoms and autumn months for time of presentation.
