The most frequent pathologies in the child´s hip can be clustered into:
Transient synovitis of the hip: (inflammation)
Usually affects children between 3 and 8 years of age. Manifests itself with groin pain with sudden onset, difficulty in walking and movement limitation. Normally there is no fever. Possible causes for this condition include a previous viral infection, allergic reactions or trauma. The pain results from the existence of an inflammation of the synovial membrane (membrane lining the inside hip). There may be an increase of fluid within the joint that distends the capsule and increases the limitation of movement. The treatment consists of bed rest for one week, anti-inflammatory medication and limitation of physical activity for at least 3 weeks.
Septic arthritis of the hip: (infection
Is a serious disease that requires early diagnosis and effective treatment. The cause is usually a bacterial infection that can lodge itself in the articulation by blood spreading from another location. The joint infection usually leads to the appearance of intra articular pus and joint destruction. Normally it has a rapid onset and is invariably accompanied by systemic signs: fever and alteration of blood tests - white blood cells, sedimentation rate and C-reactive protein increase. There is typically a large muscle spasm around the hip. The child is very complaining and any attempt to mobilize the hip triggers pain. Treatment is urgent and often with surgical drainage of pus and intra articular lavage. The liquid collected should be analyzed to make sure which bacteria caused the infection and to direct adequate treatment with antibiotics. The prognosis may not be favorable if the bacterium is too aggressive or resistant to antibiotics.
Lesions due to functional overload of the hip (excess sport or other situations where the growing hip is overloaded) can be classified as intra-articular lesions and extra articular lesions.
