Background: Ankle fractures are a common orthopedic injury, accounting for 9% of all fractures, with an increasing incidence among both young and elderly populations. These fractures often result from road traffic accidents, falls, and sports injuries. Malleolar fractures, involving the bony prominences of the ankle, are particularly prevalent and necessitate accurate reduction and stable internal fixation to prevent complications such as post-traumatic arthritis and restricted motion. This study aims to assess the functional outcomes and results of surgical treatment of malleolar fractures.
Methods: The study utilized Lauge-Hansen’s classification to analyze the mechanism of injury in 32 patients with ankle fractures. Surgical techniques included the fixation of syndesmotic injuries with anatomical fibular plates, (AFP) posterior malleolus fractures with percutaneous screws or Ellis plates, and medial malleolus fractures with tension band wiring (TBW). The outcomes were measured in terms of union time, range of motion, and stability.
Results: The most common injury mechanism was supination external rotation (SER) in 14 patients, followed by pronation external rotation (PER) in 7 patients, pronation abduction (PAB) in 6 patients, and supination adduction (SAD) in 5 patients. Syndesmotic injuries were found in 7 patients, all treated surgically except one. Posterior malleolus fractures were present in 3 patients and treated with screws or plates. Fixation of medial malleolus fractures with TBW showed better union rates and improved range of motion compared to screw fixation. Lateral malleolar fractures treated with AFP provided additional stability. The average union time was 6 to 8 weeks.
Conclusions: Anatomical reduction and stable internal fixation are crucial for the successful treatment of malleolar fractures. TBW for medial malleolus fractures and AFP for lateral malleolar fractures provide favorable outcomes. However, a larger sample size and longer follow-up duration are required to further evaluate the outcomes of ankle injuries, particularly in older patients with osteoporosis and comorbidities.
