Traumatic obturator dislocation of the hip joint: About 2 cases and review of the literature

Introduction: Traumatic dislocation of the hip is a serious lesion, and its obturator variety is rarely reported. It always reflects a high-energy trauma and represents a therapeutic emergency that requires a reduction in less than 6 h due to the risk of aseptic necrosis of the femoral head in the long term. Case report: We reported 2 cases of hip obturator dislocation in patients aged 21 and 45 years respectively, which occurred following a road accident, received for pain and functional impairment of the hip, and in a typical attitude with hip flexion, abduction, rotation and knee flexion with no downstream limb vascular-nervous injury. The emergency reduction in <6 h, in two cases, followed by functional treatment by offloading for 8 weeks and support of the limb with the resumption of walking had been authorized at 3 months with a return to sport at 16 weeks; made it possible to obtain satisfactory results at 18 months of follow-up, with an absence of a functional gene, stiffness and without signs of necrosis of the femoral head. Discussion and conclusion: Traumatic obturator dislocation of the hip constitutes serious lesions and requires early and appropriate management, reduced to closed focus, treated functionally give excellent results in the medium term. The patient must be carefully monitored over the long term and be warned of the risks he runs.
