Patterns of Pain in Adolescents with Slipped Capital Femoral Epiphysis

Managing Pediatric Hip Pain Patients with Precision

ABSTRACT

Pediatric hip pain can have orthopedic, infectious, inflammatory, neoplastic, or nonmusculoskeletal etiologies. Organizing the differential diagnosis by symptom chronicity and a determination of intraarticular versus extraarticular pain, as well as the age at pain onset, can be helpful to hone in on the cause. Clinicians should consider plain radiographs in cases of acute trauma, with concern for bony pathology, or in patients with unexplained limp or hip pain, with musculoskeletal ultrasound and magnetic resonance imaging used as advanced imaging when indicated. Relative rest with subsequent strengthening and stretching should be prescribed in nonoperative conditions, though several pediatric hip pain diagnoses require orthopedic or other specialty referral for definitive treatment. This article is a comprehensive review of hip pain etiologies in the pediatric population.

ChatGPT Responses to Common Questions About Slipped Capital Femoral Epiphysis: A Reliable Resource for Parents?

BACKGROUND

We sought to evaluate the ability of ChatGPT, an AI-powered online chatbot, to answer frequently asked questions (FAQs) regarding slipped capital femoral epiphysis (SCFE).

METHODS

Seven FAQs regarding SCFE were presented to ChatGPT. Initial responses were recorded and compared with evidence-based literature and reputable online resources. Responses were subjectively rated as "excellent response requiring no further clarification," "satisfactory response requiring minimal clarification," "satisfactory response requiring moderate clarification," or "unsatisfactory response requiring substantial clarification."

RESULTS

ChatGPT was frequently able to provide satisfactory responses that required only minimal clarification. One response received an excellent rating and required no further clarification, while only 1 response from ChatGPT was rated unsatisfactory and required substantial clarification.

CONCLUSIONS

ChatGPT is able to frequently provide satisfactory responses to FAQs regarding SCFE while appropriately reiterating the importance of always consulting a medical professional.

Diagnosis of Slipped Capital Femoral Epiphysis: How to Stay out of Trouble?

Slipped capital femoral epiphysis (SCFE) is the most common hip disorder affecting children and adolescents aged between 9 and 16 years, affecting approximately 10 per 100,000 children per year. The diagnosis of SCFE is often delayed, leading to an increased risk of complications. This study aims to provide the latest evidence concerning the causes of diagnostic delay and risk factors for SCFE and to educate general practitioners and paediatricians to help reduce delays in diagnosis and provide earlier therapeutic intervention. A literature search was conducted in the ScienceDirect and PubMed databases according to the PRISMA statement. Suitable studies for this systematic review included 22 articles discussing the aetiology of SCFE, risk factors, and causes of late diagnosis. Causes of delayed diagnosis include underestimation by patients, initial diagnostic approach by a non-orthopaedic professional, inadequate imaging, failure to recognize morphological changes, and variation in symptomatic presentation. The underlying risk factors for SCFE are likely part of a multifactorial process which involves anatomical variations and the metabolism of leptin, growth hormone, insulin, and other metabolic parameters. This review highlights the importance of early recognition and diagnosis of SCFE and proposes an algorithm for physicians to approach children who may have this condition.

A Comparison Between 3 Functional Hip Scores for Evaluation of the Pediatric Hip

BACKGROUND

This investigation aimed to determine the degree of correlation among 3 functional scales for evaluating the hip in pediatric patients and determine the correlation between measures of global function and outcome.

METHODS

We performed a prospective study of 173 consecutive patients (M age = 13 ± 3 y) being followed for developmental dysplasia of the hip (n = 122, 71%), slipped capital femoral epiphysis (n = 31, 18%), or Legg-Calve-Perthes disease (n = 20, 12%). We evaluated patients clinically, and we compiled scores for the Iowa Hip Score (IHS), Harris Hip Score (HHS), and Children's Hospital Oakland Hip Evaluation Scale (CHOHES). Patients concomitantly completed the Pediatric Outcomes Data Collection Instrument (PODCI) at the same clinic visit. We assessed Global Functioning Scale the and the Sports and Physical Functioning Core Scale of the PODCI. We determined the degree of correlation between the functional hip scales and between each scale and the PODCI scales using Spearman rank correlation coefficients.

RESULTS

The correlations between the IHS, HHS, and CHOHES scores were robust (IHS and HHS ρ = 0.991; IHS and CHOHES ρ = 0.933; HHS and CHOHES ρ = 0.938; all P < 0.001). The correlation between the Global Functioning Scale of the PODCI and the 3 hip scores was ρ = 0.343 for the IHS, ρ = 0.341 for the HHS, and ρ = 0.352 for the CHOHES (all P < 0.001). The correlation between the sports and physical functioning core scale of the PODCI and the 3 hip scores was ρ = 0.324 for the IHS, ρ = 0.329 for the HHS, and ρ = 0.346 for the CHOHES (all P < 0.001).

CONCLUSIONS

In a pediatric population with diverse hip pathology, there was a very strong correlation between scores on the IHS, HHS, and CHOHES. However, none of these 3 most commonly used hip scores correlated strongly with the global functioning scale or sports and physical functioning core scale of the PODCI. The most frequently used scores to determine the outcome of pediatric patients with hip pathology correlate strongly with each other but do not necessarily relate to global functional results.

Slipped Upper Femoral Epiphysis in Adolescents: Evolving Information on Its Mode of Presentation and Management

Background and objective Slipped upper femoral epiphysis (SUFE) is one of the most common hip pathologies in adolescents and pre-adolescents, the diagnosis of which is often missed due to delayed presentations. In this study, we aimed to conduct a retrospective analysis of SUFE cases treated in the hospital during the 15-year period from 2003 to 2018 and examine its bilateral presentation and the need for prophylactic pinning on the unaffected side. Methods This retrospective cohort study involved cases that were treated from 2003 to 2018. The case details were retrieved from the medical records department. Records older than 15 years were excluded owing to their inaccuracy, and 26 cases of SUFE were included in the final analysis. Each case was subjected to physical and radiological examinations of the symptomatic and asymptomatic hips. IBM SPSS Statistics v23 (IBM Corp., Armonk, NY) was used for data analysis. Results In this study, six of the 26 patients had bilateral SUFE and required subsequent surgical pinning. The duration of surgical interventions ranged from two to 22 months, while the mean intervention duration was 10.3 months. Among the cases, 61.5% (p<0.05) were idiopathic in nature upon documentation. However, 19% (p<0.05) of the cases were shown to be associated with an underlying condition or prior symptoms of the condition, whereas 7.6% (p<0.05) had an increased basal metabolic index; 11% (p<0.05) of the cases had an inherited family history of SUFE. A comparison between males and females showed a slightly higher frequency of complications in males (n=14) than in females (n=12) (p=0.556). The age of the patients at the presentation ranged between and 10-15 years, with an average age of 12.5 years. Conclusion Based on our findings, males were affected more than females and most of the cases were idiopathic. There is no significant evidence to support the need for prophylactic pinning of the unaffected hip. We recommend prospective studies with a larger sample of patients to gain more insight into the topic.

Litigation involving patients with slipped capital femoral epiphysis

BACKGROUND

Slipped capital femoral epiphysis (SCFE) is a hip disorder of late childhood and adolescence. Litigation involving SCFE may occur, as it is frequently diagnosed late, and/or may be temporally related to an injury. The purpose of this study was to review litigation cases involving SCFE in the US, focusing on the type of litigation (professional, premise, or product liability), the outcome of the litigation and indemnity payouts.

METHODS

Cases of litigation involving SCFE were identified using 5 legal databases and Google Scholar searching for the term "slipped capital femoral epiphysis". These databases originated as early as 1973. The data collected was the alleged complaint, type of defendant, outcome, state where filed, and amount of indemnity payout. Payout amounts were converted to 2020 US$. Statistical analyses were performed with SYSTAT® 10 software.

RESULTS

There were 135 unique cases identified which involved professional liability (103), premise liability (30), both premise and professional liability (1), and product liability (1). Complaints for professional liability cases were alleged failure in diagnosis (71), inappropriate treatment (14), both diagnosis and treatment (12), and others (7). The delay in those with an alleged late diagnosis (37 cases) was 5.8 months. The three most common specialties named as defendant(s) were primary care (31%), orthopaedic surgeons (29%), and radiologists (16%). The primary allegations against non-orthopaedic surgeons were failure in diagnosis (89%) as opposed to orthopaedic surgeons where the complaints of alleged failures in diagnosis and inappropriate treatment were equal (50%). The geographic region of the filed cases was the Northeast (44%), South (24%), Midwest (16%), and West (16%). There were no differences between premise and professional liability cases by geographic region. The overall outcome was favorable for the defendant(s) in 53% and the plaintiff in 47%; the defense prevailed in 60% of the professional liability but only 33% of the premise liability cases. The indemnity payout amount (for the 52 cases where known) averaged $1.28 million. Payout was higher in the complaints for professional compared to premise liability ($1.5 vs. $0.9 million). The average payout for those with and without avascular necrosis was $2.97 million vs. $1.02 million. For the professional liability claims, indemnity payout was most frequent in the Western US. It must be remembered that this study only represents law suits filed in the US court system. It does not include cases that might have been resolved prior to any legal action as those cases are not publicly available.

CONCLUSIONS

Reported litigation involving SCFE patients involved claims of professional liability in 77% and premise liability in 22% of located cases. Due to significant exposure, this study should serve as a reminder to all health care providers to include SCFE in the differential diagnosis of knee/thigh pain in adolescents.

Examining delays in diagnosis for slipped capital femoral epiphysis from a health disparities perspective

Slipped Capital Femoral Epiphysis (SCFE) is a skeletal pathology affecting adolescents which requires timely surgery to prevent progression. Delays in diagnosis and treatment of SCFE can negatively affect patient prognosis, and few studies have examined how health disparities and barriers to care may influence these delays. In particular, only a handful of studies have included a Hispanic patient sample, despite this ethnic group’s increased risk for the disease and unique barriers to care. A retrospective chart review was conducted for 124 patients surgically treated for idiopathic SCFE from January 2010 to September 2017. Patient data included age, facility and date of diagnosis, sex, BMI, race and ethnicity, Southwick slip angle, and insurance type. Results indicated that patients with private insurance were more likely to present with a mild slip than patients who were insured by Medicaid or uninsured, while patients without insurance were more likely to have severe slips. Patients without insurance also had a significantly higher mean slip than patients with insurance. The relationship between insurance status and slip angle degree was significant independent of race, even though Hispanic individuals were significantly more likely to have Medicaid or be uninsured. All patients without insurance, and a majority of those with Medicaid, were diagnosed in the emergency department. Time to diagnosis and slip angle were positively correlated, which suggests that longer delays led to increase of the slip angle, consistent with previous findings. Time to diagnosis and BMI were also correlated, which may be tied to socioeconomic factors, but the possibility of weight bias should not be dismissed. These results suggest that socioeconomic status and other factors may have contributed to barriers to care which led to delays in diagnosis and thus more severe slips. Future SCFE research should include health disparities variables to better inform treatment and prognosis.

Do Patient Demographics and Socioeconomic Status Influence Severity and Time to Diagnosis in Children With Stable Slipped Capital Femoral Epiphysis?

BACKGROUND

The time to diagnosis in stable slipped capital femoral epiphysis (SCFE) is often several months because of nebulous history, symptoms of knee/thigh pain, and Medicaid insurance. This study examined the impact of socioeconomic status and demographics on the time to diagnosis and SCFE severity in Indiana children.

METHODS

A retrospective review of all patients at a tertiary children's hospital with SCFE from January 2010 through March 2021 was performed. Standard demographic data and type of insurance was collected. Neighborhood Atlas Mapping was used to determine the state decile of the area deprivation index (ADI), a measure of socioeconomic status using 17 variables related to income, employment, education, and housing. Statistical analyses consisted of standard univariate and bivariate analyses; logistic regression analysis was used to determine predictors of a mild SCFE. A P<0.05 was considered statistically significant.

RESULTS

There were 142 patients; 81 male and 61 female. The average age was 12.2±1.7 years, lateral epiphyseal shaft angle of 35±19 degrees, and symptom duration of 4.5±5.0 months. There was no correlation between ADI state deciles and lateral epiphyseal shaft angle (r2=0.008) or symptom duration (r2=0.019). Insurance status and race differed by ADI deciles. In the first decile (least disadvantaged), 44% had government insurance and 89% were White; in the 10th decile (most disadvantaged), 95% had government insurance and 38% were White. Predictors of a mild SCFE were female sex [odds ratio (OR): 3.2 [1.5, 7.0]; P=0.004], symptom duration <3 months [OR: 5.3 (2.4, 11.7); P=0.00004], and White race [OR: 2.4 (1.3, 6.2); P=0.01]. Insurance status and ADI were not significant.

CONCLUSIONS

Contrary to other studies, neither insurance or socioeconomic status were associated with a delay in diagnosis or SCFE severity. The symptom duration in children with SCFE does not appear to be decreasing over the last several decades. Further investigation is required as to why.

The gold standard in the surgical treatment of the disease does not exist today, and the methods and tactics of treatment are being improved.

Diagnosis and Management of Unstable Slipped Capital Femoral Epiphysis: A Critical Analysis Review

»

An unstable slipped capital femoral epiphysis (SCFE) is characterized by the inability to walk and is associated with a high risk of osteonecrosis.

»

An unstable SCFE is less common than a stable SCFE; however, the demographics are similar in both groups of patients with SCFE.

»

The diagnosis of an unstable SCFE is characterized by a history of antecedent pain and the inability to walk on examination, and it is confirmed by radiographic assessment.

»

Management of an unstable SCFE includes closed reduction, open reduction, and capital realignment, which have all been noted to have lower rates of osteonecrosis than reported in historic reports.

»

All management approaches have certain advantages and disadvantages, and comparative studies are needed to guide clinical decision-making.

The diagnosis and management of common childhood orthopedic disorders: An update

Musculoskeletal illness represents a significant portion of office visits to primary and urgent care clinicians. Despite this, little emphasis is placed on learning pediatric orthopaedics during medical school or residency. The focus of this paper is to provide a systematic approach to this general musculoskeletal physical exam and to assist in the recognition of what conditions are normal development and what conditions require observation, workup and referral to an experienced pediatric orthopaedist.

Causes of Delayed Diagnosis of Slipped Capital Femoral Epiphysis: The Importance of the Frog Lateral Pelvis Projection

Delayed diagnosis and treatment is a universally reported problem that impairs the prognosis of slipped capital femoral epiphysis (SCFE). Quite frequently, a delayed diagnosis of SCFE is observed in spite of serial admissions and examinations of the limping adolescent. Why do health professionals globally fail to make a definitive diagnosis of SCFE during the first examination of the patient? A retrospective study of 36 adolescents treated for stable SCFE and two adolescents treated for unstable SCFE has been performed. In more than half of the delayed diagnosed stable slips (13/25, 52%), the diagnosis was set after serial examinations of the patient. Health professionals commonly order only the anteroposterior (AP) X-ray view of the pelvis when examining a non-traumatic limping adolescent. The frog lateral (FL) projection is usually spared in an attempt to limit the radiation exposure of the patient, especially in ambulating adolescents with mild symptoms. It is proposed that in the non-traumatic limping adolescent, the FL projection instead of the AP pelvis view should be requested by the health professional in order to timely diagnose a surgical emergency of the adolescent hip such as SCFE.
