Abstract
Anormal mature gait cycle consists of the stance phase, during which the foot is in contact with the ground, and the swing phase, during which the foot is in the air. The stance phaseis further divided into three major periods :the initial double-limb support, followed by the single-limb stance, then another period of double-limb support.Limp is an abnormal gait which can be caused by pain, muscular dysfunction or deformity. Limp is never normal and the cause should be established. Abnormal gait can be antalgic or nonantalgic.An antalgic gait, which is characterized by ashortening of the stance phase, is a compensatory mechanism adopted to prevent painin the affected leg. Because there is decreased contact between the affected leg and the ground, a child with such a gait may not report pain. There are several different types of nonantalgic gait; most of these donot require urgent evaluation and treatment.Limping in a child can have a variety of etiologies. A detailed history and physical examination, in addition to appropriate laboratory tests and imaging, are essential for making a correct diagnosis.
