OBJECTIVES: To determine whether immediate weightbearing after intramedullary (IM) fixation of extra-articular distal tibial fractures (OTA/AO 43-A) results in a change in alignment before healing.
DESIGN: Retrospective review.
SETTING: Level 1 trauma center.
INTERVENTION: IM nailing of distal tibial fractures.
PATIENTS/PARTICIPANTS: Fifty-three patients with 54 fractures, all of whom could bear weight as tolerated postoperatively. Eighteen fractures were OTA/AO 43-A1, 20 OTA/AO 43-A2, and 16 OTA/AO 43-A3; 20 fractures were open.
MAIN OUTCOME MEASUREMENTS: Change in fracture alignment or loss of position.
RESULTS: Average change from initial angulation at final follow-up was 0.52 ± 1.49 degrees of valgus and 0.48 ± 3.14 degrees of extension. Final alignment was excellent in 14, acceptable in 28, and poor in 12; 2 fractures went from acceptable initial alignment to poor final alignment; and 2 fractures went from excellent to acceptable alignment. Seven fractures had an improvement in alignment over time. Two fractures required free-flap coverage and 4 required staged grafting because of bone loss. Ten fractures had an unplanned return to the operating room (5 for infected nonunion requiring implant exchange, 3 for infection requiring debridement without implant revision, and 2 for aseptic nonunion). No patient had revision for implant failure.
CONCLUSIONS: Immediate weightbearing after IM fixation of extra-articular distal tibial fractures (OTA/AO 43-A) led to minimal change in alignment and seems to be safe for most patients. Complications were consistent with those reported in previous non-weightbearing cohorts.
