Abstract

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. There is a long list of possible diagnoses. A complete history and thorough physical examination are the most helpful tools in sorting out the various causes of limping. Laboratory tests and imaging studies should be based on findings in the history and physical examination. Certain causes of limping must be diagnosed at the first visit. Sometimes the cause of limping cannot be determined, and after exclusion of any serious disease, the child should be observed. Many of them will have spontaneous resolution without treatment.
