ASPECTS ÉPIDEMIOLOGIQUES ET THÉRAPEUTIQUES DES FRACTURES ACETABULAIRES CHEZ LE SUJET ÂGÉ

INTRODUCTION: Management of acetabular fracture in the elderly patients is becoming an increasingly topic of debate. Data from different parts of the world specified particularities of their patients. AIM: To describe patterns of these fractures in the Tunisian patients aged > 60, which can contribute to management and preventive plans. METHODS: We performed a retrospective review from 1997 to 2016 treated at the Charles Nicolle university hospital. Information regarding demographics, co morbidities, mechanism of injury, Injury Severity Score (ISS), types and levels of injury, treatment type, and mortality were collected. RESULTS: The mean age of our patients was 68,6 years (range 60–94 years). The male to female ratio was 3:85.Main causes were motor vehicle accident. Most of our patients were in good health. The associated lesions were very frequent and present in 64.7% of cases with a clear predominance of cranio-fascial trauma, with a median of the ISS score at 11. According to the Judet and Letournel classification, 18 elementary fractures and 16 complex fractures were reported with predominance of the anterior column-posterior hemitransverse fracture pattern. Posterior wall fracture in the elderly is often associated with comminution and / or marginal impaction and / or posterior dislocation of the hip. Fractures of the anterior segment are often associated with hip protrusion and / or quadrilateral plate involvement and / or the superomedial roof impaction or "Gull sign". CONCLUSION: As our population continues to age, traumatic acetabular fractures will become more prevalent. Appropriate screening strategies, treatment and prevention plans will need to be developed to improve outcomes in this devastating injury.
