Abstract:【Objective】 To explore the influencing factors of ulnar nerve dysfunction after open reduction and internal fixation of intercondylar fracture of humerus. 【Methods】 The clinical data of 60 patients with humeral intercondylar fractures treated in our hospital from January 2017 to December 2019 were analyzed retrospectively. The age, gender, fracture classification, surgical approach, ulnar nerve treatment and other intraoperative related factors were recorded, and the patients were followed up. According to whether there was ulnar nerve dysfunction after operation, the patients were divided into asymptomatic group (control group) and symptomatic group (observation group). The risk factors of ulnar nerve dysfunction were analyzed by univariate analysis and multivariate logistic regression analysis. 【Results】 There were significant differences in surgical approach, ulnar nerve treatment and plate placement between the two groups (P<0.05); Multivariate logistic regression analysis showed that the bilateral approach of triceps brachii, anterior ulnar nerve and parallel plate were independent risk factors for postoperative neurological dysfunction (OR=1.992, 2.643, 2.282, P<0.05). 【Conclusion】 The incidence of ulnar nerve dysfunction after open reduction and internal fixation of intercondylar fracture of humerus is high. Bilateral approach of triceps brachii, anterior ulnar nerve and parallel placement of steel plate are independent risk factors of ulnar nerve dysfunction. Clinically, doctors should choose the appropriate surgical approach, plate placement and whether the ulnar nerve is in front according to the individual differences of patients, so as to minimize the occurrence of postoperative ulnar nerve dysfunction.
