The Role of Point of Care Ultrasound in Evaluating Paediatric Patients With Limp: An Illustrative Case Series

Area of Science:

• Pediatric Emergency Medicine
• Musculoskeletal Imaging
• Point-of-Care Ultrasound (POCUS)

Background:

• Acute refusal to weight-bear or limping is a frequent pediatric emergency department (PED) presentation.
• The broad differential diagnosis for pediatric lower limb complaints presents significant diagnostic challenges.
• Some underlying causes are critical or life-threatening, necessitating prompt and accurate diagnosis.

Purpose of the Study:

• To highlight the utility of point-of-care ultrasound (POCUS) in diagnosing acute pediatric lower limb conditions.
• To demonstrate how POCUS assists in managing challenging cases presenting to the PED.
• To showcase POCUS's role in expediting decision-making for pediatric patients with lower limb complaints.

Main Methods:

• Review of pediatric cases presenting with acute lower limb symptoms to the PED.
• Application of point-of-care ultrasound (POCUS) as a primary diagnostic tool.
• Correlation of POCUS findings with clinical presentation and subsequent management.

Main Results:

• POCUS proved instrumental in establishing diagnoses that were initially unclear.
• The use of POCUS expedited the diagnostic process for acute lower limb presentations.
• POCUS facilitated appropriate management strategies in complex pediatric cases.

Conclusions:

• Point-of-care ultrasound (POCUS) is a valuable tool for pediatric emergency physicians managing lower limb complaints.
• POCUS improves diagnostic accuracy and expedites care for children presenting with limping or refusal to weight-bear.
• Integrating POCUS into the diagnostic pathway enhances patient management in the PED.
