Evaluation of Hip Pain and Management of Toxic Synovitis in the Ultrasound Era

Point-of-Care Ultrasound (POCUS) for Sideline Youth Sports Coverage

PURPOSE OF REVIEW

The purpose of this review is to discuss the use of point-of-care ultrasound for sideline youth sports coverage.

RECENT FINDINGS

Participation in youth sports has been increasing, with trends that athletes are specializing earlier and competing at higher levels at younger ages (NSCH 2019, Fabricant 2013). Point-of-care ultrasound (POCUS) utilizes non-invasive imaging to diagnose and manage various musculoskeletal conditions ranging from traumatic injuries, such as fractures and intramuscular hematomas, to early screening for conditions such as asymptomatic knee lesions. Since it is well-tolerated by children and adolescents and allows for easy accessibility for sideline care, POCUS could provide a strong alternative to other imaging modalities such as x-ray and magnetic resonance imaging (MRI) as both have their limitations. Youth sideline sports coverage could be enhanced with immediate medical attention from ultrasound-trained medical professionals. On the sidelines of a traumatic injury, POCUS expedites patient care with immediate examination of acute injuries. In low resource and hard-to-reach locations such as a rural youth sporting event, it can be key in the triaging of injuries. As a supplement to a physical exam, the risk of a misdiagnosis is reduced, and a long, expensive trip to the hospital for unnecessary imaging studies may be avoided. Ultrasound is a versatile, non-invasive, radiation-free imaging modality that serves as an accessible option for sideline coverage at youth sporting events. Ultrasound is well-tolerated by children and adolescents. It can be used to evaluate, diagnose, and manage a range of musculoskeletal conditions at the sidelines of youth sports.

Transient synovitis of the hip: Current practice and risk of misdiagnosis

INTRODUCTION

Transient synovitis (TS) is a common and benign cause of hip pain in children, but must be distinguished from more serious entities such as septic arthritis, osteomyelitis, and pyomyositis. Our objectives were to determine the risk of missed bacterial musculoskeletal infection and rates of diagnostic testing in children diagnosed with TS.

METHODS

We performed a cohort study using the Pediatric Heath Information System of children 1-10 years diagnosed with TS in the ED. We determined rates of missed bacterial musculoskeletal infection (defined as a new diagnosis of septic arthritis, osteomyelitis, or pyomyositis within 14 days of initial ED visit). We described the initial diagnostic evaluation and ED management of children diagnosed with TS and variability between sites.

RESULTS

We analyzed 6419 encounters from 37 hospitals. 62 (1.0%, 95%CI: 0.7-1.2%) children were diagnosed with a missed bacterial musculoskeletal infection. Children with missed infection were younger than those without (median age 2.6 vs. 4.6 years, p < 0.01). Serum laboratory testing was performed in 76% of encounters with minimal variation across sites. There was significant variation in the rates of hip ultrasound by site (2 to 92%), which has increased in use over time (from 42% in 2016 to 62% in 2021).

CONCLUSION

In this large observational study, missed bacterial musculoskeletal infection in children diagnosed with TS was rare but more common in younger children. The optimal combination of bloodwork and radiographic testing, especially ultrasound, to distinguish TS from more serious disease remains unclear.

Common Ultrasound Applications for Pediatric Musculoskeletal Conditions

PURPOSE OF REVIEW

To discuss the use of ultrasound for diagnosis and management of common pediatric musculoskeletal conditions through a case-based approach.

RECENT FINDINGS

Ultrasound is an essential diagnostic modality in the early detection of developmental dysplasia of the hips and can be used as early as 6 weeks of age when the ossific nucleus has not developed yet. Ultrasound is helpful in diagnosing traumatic injuries such as fractures and intramuscular hematomas, can visualize fracture healing at early stages, and can also be used to guide aspiration of hematomas that can help with decreasing pain and faster recovery. Ultrasound is superior to radiographs in evaluating joint effusions and soft tissue infections or masses and is better tolerated by children compared to other imaging modalities such as magnetic resonance imaging (MRI). Ultrasound is an easily accessible, affordable, non-invasive, and radiation-free imaging modality that is well tolerated by children and their families. It can aid in the diagnosis and management of a wide variety of musculoskeletal conditions including developmental, traumatic, and infectious etiologies, as well as in the evaluation of superficial soft tissue masses.

Evaluation of efficacy and safety of traditional Chinese medicine in the treatment of hip synovitis in children: A protocol for systematic review and meta-analysis

BACKGROUND

Hip synovitis is a common hip disorder in children and a frequent cause of hip or groin pain in children. Its onset is rapid and poses a threat to patient health. Conventional treatment methods have suboptimal efficacy and large side effects. Clinical study surface, the therapeutic effect of traditional Chinese medicine (TCM) on hip synovitis in children is obvious. Therefore, we aimed to systematically review the efficacy and safety of TCM on hip synovitis in children.

METHODS

We will search databases including PubMed, Web of Science, EMBASE database, Cochrane Library, MEDLINE, Wanfang Data, Chinese biomedical literature database, China National Knowledge Infrastructure, Chinese science and technology journals database, and World Health Organization International Clinical Trials Registry Platform (since the databases were established). We also searched secondary resources, including the reference lists of studies. Included articles were carefully screened and reviewed by 2 researchers. Statistical analysis was performed using Review Manager 5.3 software.

RESULTS

This study will comprehensively evaluate the efficacy and safety of TCM for the treatment of hip synovitis in children.

CONCLUSION

This systematic review explores the efficacy and safety of TCM for the treatment of hip synovitis in children and provides an update on its clinical use.
