OBJECTIVE:: To determine if time to weight bearing (WB) is associated with complications in operatively treated pelvic ring injuries. DESIGN:: Retrospective cohort study. SETTING:: Academic level-I trauma hospital. PATIENTS:: Two-hundred eighty-six patients with pelvic ring injuries treated operatively over a 10-year period (OTA/AO 61-B1-3, 61-C1-3; Young-Burgess LC1-3, APC1-3, Vertical shear). INTERVENTION:: Patients were stratified into early (≤8 weeks) and late (>8 weeks) time to full WB groups. MAIN OUTCOME MEASURE:: Composite outcome of implant failure [broken screw(s)/plate(s), screw(s) loosening], revision surgery, and malunion. RESULTS:: We identified 286 patients with mean age 39.9 years old (range 18-81) and an average follow up of 1.2 years (1.0-9 years). There were 132 and 154 patients in the early and late WB groups respectively. A total of 142 Young-Burgess lateral compression type (LC)-I, 48 LC-2, 23 LC-3, 10 anterior-posterior compression (APC)-I, 45 APC-2, 8 APC-3, and 8 vertical shear (VS) injuries were noted. Complications were noted in 47 patients (16%). Complications included 18 implant failures, 16 malunions, and 13 patients that required revision operations for loss of reduction. Time to WB was not associated with composite complication rates (p=0.24). APC-2, LC-3, and injuries with bilateral rami fractures were noted to have a higher complication rates independent of time to WB (p= 0.005, 0.03, 0.03, respectively). CONCLUSION:: No difference in implant failure, malunion, or early loss of reduction between operatively treated pelvic ring injuries allowed to WB as tolerated before eight weeks compared to those who remained on protected WB protocol for any time greater than eight weeks was noted. This data may provide information to support early WB protocols. LEVEL OF EVIDENCE:: Diagnostic – Level III
