The study aimed to compare complications and functional outcomes in patients with supination adduction type II (SAD) injuries versus those with torsional ankle injuries (TAI), focusing on a large cohort of patients treated for ankle fractures.
The analysis included 1,531 patients, revealing that SAD injuries, although less common (4.2%), occurred in younger individuals and were often the result of higher-energy events, leading to more associated injuries.
While SAD patients showed a higher incidence of posttraumatic arthrosis (80% vs. 40.9%), the rates of complications and functional outcomes over six years post-injury were generally similar to those of TAI patients, indicating that despite the severity, SAD injuries did not lead to significantly
