Pathologic fractures of long bones in Nigerian children

Abstract

Background: Pathologic or spontaneous fractures are recognised causes of morbidity in children. There is a paucity of data on their aetiology and patterns in African children. Methods: A combined retrospective and prospective study of 47 children aged 15 and below with pathologic fractures of long bones seen from January 2000 to December 2006. The setting was the Orthopaedic and Traumatology department of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. Results: A total of 47 patients with a mean age of 5.3 years ± SD with pathologic fractures of 50 long bones were seen and treated. The most commonly affected bones were the femur (28%), tibia (28%) and humerus (26%). Chronic osteomyelitis following inadequately treated acute haematogenous osteomyelitis was the commonest cause of pathologic fractures (74.5%). The mean duration of fracture union was 6.8 ± 2.3 months and the outcome was satisfactory in 91.4% of cases. Conclusions: The aetiology of pathologic fractures in the African population is different from their causes in Caucasian children. Chronic osteomyelitis following inadequately treated acute haematogenous osteomyelitis continues to plague many children in our environment. © EPOS 2008.
