PURPOSE: To assess the morbidity of open reduction internal fixation (ORIF) of posterior malleolus fractures (PMFs) in the setting of trimalleolar ankle fractures.
METHODS: A retrospective review of 79 trimalleolar ankle fractures was performed to identify need for syndesmotic fixation, blood loss, operative/tourniquet time, complications, and reoperations. Patients with PMF ORIF (n = 38) were compared to those with no fixation (n = 41). A subanalysis of patients with small PMFs (< 25%) was performed.
RESULTS: The PMF ORIF group required less syndesmosis fixation (proportional difference (PD) - 44.6%, 95% confidence interval (CI) - 61.8 to - 23.0%), had more blood loss (MD 20 ml, CI 0-40), longer operative times (MD 53.0 min, CI 35.9-70.1), longer tourniquet times (MD 26 min, CI 4-33), and had no difference in postoperative joint step-off or concentrically reduced joints. The PMF ORIF group had more postoperative complications (PD 26.9%, CI 6.3-44.8%) and a trend for more reoperations (PD 13.6%, CI -3.4 to 29.6%). Wound complications were more common in the PMF ORIF group (PD 26.5%, CI 6.9-43.6%), resulting in 5 (16.1%) irrigation and debridement procedures. On analysis of patients with small PMFs (n = 42), PMF ORIF (n = 15) resulted in longer operative/tourniquet times and had no observed difference in postoperative joint step-off, concentrically reduced joints, need for syndesmotic fixation, blood loss, or complications/reoperations.
CONCLUSION: PMF ORIF in the setting of trimalleolar ankle fractures was associated with increased operative/tourniquet times, blood loss, wound complications, and did not eliminate the need for syndesmosis fixation.
