Inflammation of the layer that lines the joint of the hip also known as synovial membrane.
The cause is an inflammatory reaction of unknown origin. In most cases, a viral infection has occurred in the days prior to the limp (catarrh clinical picture or intestinal episode). It usually involves only one hip.
The most frequent symptoms are pain in the hip region, in the groin or in the frontal region of the thigh. The limp originates due to pain. In lactating infants or young children, the only symptom we might observe is that they do not want to get up or move. Low grade fever may occasionally appear, but high fever rarely does. The symptoms usually last 7-10 days, although sometimes they may last several weeks.
Diagnosis is clinical, based on data from the patient's history and a physical examination. If there are diagnostic doubts or the clinical picture is very prolonged or severe, it may sometimes be necessary to carry out X-rays to rule out other pathologies.
Treatment is based on rest and anti-inflammatory drugs, for example ibuprofen.
