Abstract
Limping is a common presenting complaint in children. Despite this, it remains to be a diagnostic challenge for treating physicians due to an expanded list of etiologies. It arises from a spectrum of disorders, ranging from physiological variations of gait at different stages of development to systemic causes, such as inflammatory diseases or musculoskeletal infections. On rare occasions, non-musculoskeletal causes could result in limping. The diagnostic challenge increases in younger age children where a detailed physical examination that helps identify the exact source of pathology may not be possible. In older patients who have a well-developed gait cycle, the physical assessment might be easier. Clinical assessment in a child presenting with a limp includes gait analysis, which is essential to guide the appropriate request of diagnostic laboratory tests and imaging studies. In this paper, we provide a practical guide for a trainee in General Pediatric and Pediatric Rheumatology on an approach to a limping child, aiming to identify the common causes of limping and to describe normal and abnormal gait cycles. We also discuss other diagnostic considerations in the assessment of these children.
