Limp is defined as an uneven, jerky, or laborious gait, usually caused by pain, weakness, or deformity [1]. It is a common complaint in childhood, accounting for 4 per 1000 visits in one pediatric emergency department [2]. Limp is caused by benign and life-threatening conditions (table 1), and the management varies from reassurance to major surgery depending upon the cause [2,3]. The cause of limp usually can be determined through a careful history and physical examination.
