Avascular necrosis as a complication of septic arthritis of the hip in children.

Seventy-one hip joints in 69 infants and children with pyogenic arthritis were studied. Twenty joints (28%) with the radiographic characteristics of avascular necrosis were identified and the changes classified into 3 groups: Group 1 (infants up to the age of 6 months) had ischaemic changes characterized by the absence or delayed appearance of the epiphyseal ossification centre; Group 2 (children aged between 7 months and 5 years) showed disappearance of this centre whether followed by revascularization or not, with the shape of the cartilaginous femoral head preserved in either case; and in Group 3 (children 6-16 years of age) the femoral epiphysis was either totally or partially involved with increased bone density; collapse of the head may or may not have occurred. At follow-up for between 2 and 15 years, a trend towards more severe deformities was seen in the 11 hip joints of Group 3 when compared to the 9 hip joints in Groups 1 and 2. The opposite was observed in relation to less severe deformities. Early diagnosis and treatment of infection is mandatory in patients with pyogenic arthritis and increased intra-articular hydrostatic pressure, or those with septic thrombosis of the epiphyseal vessels, which could cause avascular necrosis (AVN).

Early diagnosis of septic arthritis of the hip in neonates.

Fourteen neonates with septic arthritis of the hip, which had been diagnosed late, were reviewed with the aim of establishing the difficulties of making an early diagnosis. The history, physical signs, blood tests and examination of the synovial fluid are the most important guidelines. Radiography was not helpful as less than 50% of cases show early signs, most often a joint effusion. Early diagnosis and surgical drainage are necessary to avoid permanent damage to the cartilaginous femoral head.

Transient arthritis of the hip in children (a study of 74 cases).

The author studied 74 cases of transient arthritis of the hip in children. Limp and limitation of internal rotation were present in all cases and in the great majority of patients the symptoms disappeared during the first week, signifying remission of the synovitis. Early radiographic changes are rare and were observed in only 3% of the cases. They showed increased joint space or osteoporosis of the proximal third of the femur. Physical examination and careful follow-up are the most important factors in diagnosis and evaluating the prognosis.

Observation hip.

"Observation Hip" is a provisional diagnosis. Although transient arthritis is the most frequent pathology, it is important to establish a diagnostic routine to consider the various types of hip pathology. Physical examination and clinical evolution are the most important factors in making a specific diagnosis.
