VALENTE, Henrique Gonçalves et al. Injury of the external obturator muscle in professional soccer athletes. Rev Bras Med Esporte [online]. 2011, vol.17, n.1, pp. 36-39. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922011000100007.
Several studies have investigated different injuries that occur among soccer players. However, it has been noticed that none has mentioned injury to the external obturator muscle. As a small and monoarticulated muscle, its incidence is probably low and barely documented in the literature. Therefore, the aim of this study is to present four external obturator muscle strain cases in a professional soccer team in 2008. The data was collected from a database using the software Sistema de Preparação Desportiva which provides data such as name, diagnosis, trauma mechanism, clinical history, time away from training and progress. All athletes who undertook Magnetic Resonance Imaging (MRI) of the external obturator muscle and presented rupture of the external obturator muscle were included in the study. Four external obturator muscle strain injuries were identified from a total of twenty-eight muscle strains during the year of 2006. All athletes presented diffuse pain on the hip for medial and lateral rotation of the joint. The predominant injury mechanism was lateral rotation of the trunk over the femur on closed kinetic chain. It was concluded that external obturator muscle strain injuries can be mistaken for those related to the hip adductor muscles due to the reported pain area. Clinical examination should be based on the athletes' report and functional tests, mainly for the hip rotator muscles. The MRI scan was essential to the location, classification and evaluation of the injury size.
