ABSTRACT

Background: Legg-Calve-Perthes disease is distinguished by an avascular necrosis of the femoral head. Of unknown etiology and self-limiting character this pathology has a prevalence of 0.5 to 10.8 cases per 100,000 children and teenagers. Some authors have observed and described a favorable outcome in patients in whom the disease occurs at a younger age to 6 years old. Material and methods: A retrospective, longitudinal, descriptive and observational study. There were included patients wiht LCP disease with complete clinical and radiological records for the variables to be studied. We evaluated variables such as gender, age at onset of the disease, current age, side affected, stage to the disease determined by the Herring classification at the moment of hospital admission, hip sequelae (Femoroacetabular impingement) at the time of skeletal maturity. Results: 61 patients included in the study. Sixty eight independently evaluated hips (7 patients with bilateral involvement). Fifty five male patients (90.1%) and 6 female (9.8%). Forty six hips in children under 6 years (67.6%) and 22 hips in patients over 6 years (32.4%). According to age group and in relation to the classification of Herring when onset of the pathology, poor results were found in 63.04% of patients younger than 6 years and 63.63% in patients over 6 years evaluated when they reached skeletal maturity. Conclusion: There was a close relationship between the initial stage of each patient according to the lateral pillar classification and the likelihood of developing FAI at the time of skeletal maturity. There is no relationship between age of onset and disease progression.
Evidence level: III
