629 Demographic and Epidemiological Analysis of Pelvic Wing and Acetabular Fractures

Aim Pelvic and Acetabular fractures (PAFs) are a significant concern, particularly in older individuals with osteoporosis. This study presents a 6-year retrospective review conducted at a tertiary trauma centre in the UK to analyse the incidence, demographics, and associated factors of PAFs. Method Data encompassed pelvic ring and acetabular fractures from January 2017 to January 2023, categorized by Young and Burgess or Letournel classifications. Parameters included age at injury, gender, BMI at presentation, injury mechanisms, and related orthopaedic and non-orthopaedic injuries. Results The study assessed 2,128 pelvic fractures, comprising 1,093 pelvic ring fractures and 1,035 acetabular fractures. Acetabular fracture patients were older (average 61.5 vs. 56.4 years) and more frequently male (67% vs. 46%) than pelvic ring fracture patients. Both groups displayed similar average BMI and surgical management rates (49.8%). Among pelvic ring fractures, Lateral compression type-I fractures predominated at 53.7%, while anterior column and posterior hemitransverse fractures were most common in acetabular fractures (23.6%). High and low-impact falls were the primary causes for pelvic ring (24.0%) and acetabular fractures (30.8%). Interestingly, almost two-thirds of pelvic fractures occurred in isolation without additional orthopaedic polytrauma. Organ lacerations/contusions were the predominant associated non-orthopaedic injuries, followed by pneumothorax and brain injuries, with fewer other injuries. Conclusions This study offers insight into PAFs at a UK trauma centre, particularly in sub-classifying pelvic fractures based on the Young-Burgess and Letournel classifications, a rarity in existing literature. These findings contribute to international comparisons and inform evidence-based policies for healthcare resource planning and postoperative care.
