Dislocation of total hip prostheses is a multifactorial problem, with contributing factors from the patient, the implant, and the surgeon. It causes pain and patient dissatisfaction and must thus be reduced immediately or few days after its occurrence. Chronic dislocation of a total hip prosthesis refers to a dislocation which is unreduced at least 3 weeks (21 days) after its occurrence. We report clinical and radiological features, the surgical technique used for the treatment and outcome of a 11-year duration spontaneous chronic asymptomatic bilateral postero-superior dislocation of cemented total hip prostheses caused by excessive inclination of acetabular components in a 59-year-old patient. A 2-month-interval bilateral total hip revision has been carried out after continuous trans-condylar skeletal traction on Boppe splint. The patient made an uneventful recovery. At 7-year-follow up, the patient was satisfied with Postel Merle d’Aubigné score of 17/18 and Harris Hip Score of 99/100.
