ABSTRACT=<sec><title>Purpose</title><p>The purpose of this study was to identify which of the risk factors would contribute to the contralateral fracture in very elderly patients after intramedullary nail fixation.</p></sec><sec><title>Methods</title><p>Clinical data of 227 intertrochanteric fracture patients aged 80 years or older were retrospectively reviewed. Intramedullary nails (IMNs) were used on all of the patients. Potential risk factors for contralateral hip refractures were determined using univariate and logistic regression analyses.</p></sec><sec><title>Results</title><p>Contralateral hip refractures occurred in 11 patients (4.84%). Univariate analysis revealed that age, gender, body mass index, fracture classification, hematocrit, D-dimer, and CRP level were not associated with contralateral fractures (<italic>P </italic>&gt; 0.05). However, neurological diseases, cardiovascular disease, and visual impairments were significantly associated with contralateral fractures (<italic>P </italic>&lt; 0.05). Multivariate analysis further revealed that neurological diseases (OR 4.25, <italic>P </italic>= 0.044) and visual impairments (OR 5.42, <italic>P </italic>= 0.015) were independent risk factors associated with contralateral refractures.</p></sec><sec><title>Conclusion</title><p>To prevent contralateral refractures, more attention should be paid to elderly intertrochanteric fracture patients with underlying neurological disease and visual impairments.</p></sec>
