Open Obturator Hip Dislocation: A Case Report and Review of the Literature.

Case: An open obturator dislocation with associated pelvic ring injury and perineal wound underwent fixation and aggressive debridement. Despite this, the patient proceeded to infection requiring additional debridements and prolonged intravenous antibiotics. At 18 months postinjury, the patient developed avascular necrosis and significant heterotopic ossification; however, she was able to ambulate.
Conclusions: Open obturator dislocations of the hip require a multidisciplinary team. Despite prompt antibiotic therapy and aggressive debridement, patients are at high risk of infection because of the microbial environment in this region. Open obturator hip dislocations are at significant risk of avascular necrosis despite timely reduction.
