Outcomes After Acute Versus Staged Fixation of Complete Articular Tibial Plafond Fractures.

Abstract

To determine the outcomes after acute versus staged fixation of complete articular tibial plafond fractures. Retrospective cohort study. Single Level 1 Trauma center. 98 skeletally mature patients with OTA/AO 43C type fractures who underwent definitive fixation with plate and screw constructs and had a minimum 6 months of follow-up. Acute open reduction internal fixation (aORIF) versus staged (sORIF) definitive fixation. Rates of wound dehiscence/necrosis and deep infection. Acute (N = 40) versus staged (N = 58) ORIF groups had comparable rates of vascular disease, renal disease, and substance/nicotine use, but aORIF patients had higher rates of diabetes mellitus (10% vs. 0%, P < 0.001), which correlated with higher American Society of Anaesthesiologist scores (>American Society of Anaesthesiologist 3: 37.5% vs. 13.8%, P = 0.02). Both groups achieved anatomic/good reductions, as determined by postoperative CT scans, at rates greater than 90%; however, the sORIF group required modestly longer operative times to achieve this outcome (aORIF vs. sORIF: 121 vs. 146 minutes, P = 0.02). Postoperatively, both groups had similar rates of wound dehiscence (2.5% vs. 6.9%, P = 0.65), superficial infections (10% vs. 17.2%, P = 0.39), and deep infections (10% vs. 8.6%, P = 0.99). While the injury pattern itself required free flap coverage in 1 patient in each group, unplanned free flap coverage occurred in 10.0% and 10.3% of aORIF and sORIF groups, respectively. Overall, rates of unplanned reoperations, excluding ankle arthrodesis, did not differ between groups (aORIF vs. sORIF:12.5% vs. 25.9%, P = 0.13). In select patients managed by fellowship-trained orthopaedic traumatologists, acute definitive pilon fixation can produce acceptable outcomes. Therapeutic Level III.
