• OBJECTIVES
    • To determine whether immediate weight bearing after intramedullary fixation of extra-articular proximal tibia fractures (OTA/AO 41A) results in change of alignment before union.
  • DESIGN
    • Retrospective Review.
  • SETTING
    • Level I and Level II Trauma Center.
  • PATIENTS/PARTICIPANTS
    • Thirty-seven patients with 37 proximal tibial fractures, all whom could bear weight as tolerated postoperatively. Eighteen fractures were OTA/AO 41-A2, and 19 were OTA/AO 41-A3.
  • INTERVENTION
    • Intramedullary nailing of extra-articular proximal tibia fractures.
  • MAIN OUTCOME MEASUREMENTS
    • Change in fracture alignment or loss of reduction.
  • RESULTS
    • The average change in coronal alignment at the final follow-up was 1.22 ± 1.28 degrees of valgus and 1.03 ± 1.05 degrees of extension in the sagittal plane. Twenty-five patients demonstrated excellent initial alignment, 10 patients demonstrated acceptable initial alignment, and 2 patients demonstrated poor initial alignment. Five patients demonstrated a change in alignment from excellent to acceptable at the final follow-up. No patient went from excellent or acceptable initial alignment to poor final alignment. Five patients required unplanned secondary surgical procedures. Two patients required return to the operating room for soft-tissue coverage procedures, 2 patients required surgical debridement of a postoperative infection, and 1 patient underwent debridement and exchange nailing of an infected nonunion. No patient underwent revision for implant failure or loss of reduction.
  • CONCLUSION
    • Immediate weight bearing after intramedullary fixation of extra-articular proximal tibia fractures (OTA/AO 41A) led to minimal change in alignment at final postoperative radiographs.
