Acetabular fractures requiring an anterior approach have historically been delayed, allowing a stable clot to form before creating large surgical exposures. The purpose of this study was to determine whether immediate fixation of acetabular fractures within 24 hours using an anterior approach demonstrates notable difference in blood loss, length of stay (LOS), complications, or mortality compared with acetabular fractures treated after 24 hours. Ninety-three patients were optimized for surgery within 24 hours of injury. Thirty-two patients underwent fixation within 24 hours using an anterior approach to the acetabulum. Demographics, hours from injury to operating room, fracture classification, embolization, surgical approach, intraoperative cell salvage use, Charlson Comorbidity Index, American Society of Anesthesiologists class, Injury Severity Score, and Abbreviated Chest Injury Score were recorded. Estimated blood loss, transfusions, intensive care unit stay, total hospital LOS, complications, and mortality rates were compared. No statistically significant differences were observed in fracture classification, blood loss, or intraoperative transfusions between the immediate and delayed fixation groups. Six patients in the delayed group (9.8%) returned to the operating room for a complication compared with one patient (3.1%) in the immediate group ( P = 0.42). Three patients in the delayed group (4.9%) developed a surgical site infection compared with none (0%) in the immediate group ( P = 0.55). The immediate group had an average LOS of 7 days compared with 11 days in the delayed fixation group ( P = 0.01). No notable differences were observed in 30- or 90-day mortality rates. Medically optimized patients with acetabular fractures who undergo immediate fixation through an anterior approach do not seem to have an associated increase in blood loss, transfusions, or mortality. Prompt surgical management may also be associated with a shorter preoperative and postoperative LOS. Therapeutic level III.
