Objectives: The aim of this retrospective study is to evaluate if
Rush nail fixation still has a role in distal fibular fractures surgery compared with locking plate in terms of fixation quality, complications, functional results and patient satisfaction level.Methods: This study included ۱۰۹ patients (average age ۵۶.۰۵), who had undergone operative treatment for bi- or trimalleolar fractures between ۲۰۰۹ and ۲۰۱۴. The patients were evaluated retrospectively, divided in group A (۵۷ patients treated with Rush nail) and group B (۵۲ patients treated with locking plate). The patients were evaluated at an average ۴.۹ years of follow-up (SD: ۱.۰۱) with Olerud-Molander
Ankle Score (OMAS), American Orthopaedic Foot and
Ankle Society - Ankle-Hindfoot Scale (AOFAS) and Visual Analogue Scale (VAS) for clinical outcomes. Xrays were conducted to assess ankle osteoarthritis using the classification system by Takakura and joint space symmetry using measurements in comparison with contralateral ankles.Results: The groups were homogeneous regarding age and gender. Patients treated with Rush Nail fixation (Group A) showed statistically significant worse clinical results at functional scores (۷۸.۱ Group A versus ۸۸.۷ Group B at the OMAS (P<۰.۰۵); ۸۳.۱ Group A versus ۹۰.۱ Group B at the AOFAS (P<۰.۰۵); higher pain levels in the VAS (۳.۹ Group A versus ۲.۴ Group B) and lower satisfaction rates (۵۲.۶% Group A versus ۷۳.۱% Group B (P<۰.۰۵)) in comparison with patients treated with locking plate fixation (Group B). However, infections rate was significantly lower in Group A (۱.۸%) than in Group B (۹.۶%) (P<۰.۰۵). Radiographic evaluation showed more cases of posttraumatic osteoarthritis in Group A (۳۵.۱% Group A versus ۱۵.۴% Group B (P<۰.۰۵)) and worse results in regards to restoration of joint space symmetry (۴۵.۶% Group A versus ۷۳.۱% Group B (P<۰.۰۵)).Conclusion: Results of current study indicates that even though plating of lateral malleolus in bimalleolar and trimalleolar fractures is superior in fracture reduction quality, early functional recovery, reduced incidence of posttraumatic osteoarthritis and greater patient satisfaction,
Rush nail fixation still provides acceptable clinical results with a lower infection rate. Therefore Rush nails could be considered as a valid choice in selected patients with high risk of soft tissue complications or low functional demand. Level of evidence: III
