Tibial Shaft Fracture Combined with Occult Posterior Malleolar Fracture and Risk Factors
Objective:To analyze the situation and risk factors of patients with tibial shaft fracture complicated with occul-ted posterior malleolar fracture.Methods:A total of 120 patients with tibia shaft fracture from March 2018 to January 2023 were prospectively selected as the study objects.X-ray,CT and MRI were used to examine the patients,respectively,and the detection rate of occulted posterior ankle fracture was calculated by different examination methods.According to the imaging results,the patients were divided into the occurrence group and the non-occurrence group according to whether there were concealed posterior ankle fractures.The general data of the two groups were analyzed,and the risk factors affecting the occurrence of concealed posterior ankle fractures were analyzed by univariate analysis and multivariate Logis-tic regression analysis.Results:A total of 42 patients with concealed posterior malleolar fracture were detected,the inci-dence was 35.00％(42/120).The length of the tibial fracture line and the distance from the lowest point of the fracture line to the tibia-distal articular surface were longer in the occurrence group than in the non-occurrence group.The inci-dence of non-spiral fracture and the distal fracture site were higher than those in the non-occurrence group(P＜0.05).The length of the tibial fracture line,the distance from the lowest point of the fracture line to the tibia-distal articular sur-face,non-spiral fracture,and distal fracture were associated with occssive posterior malleolar fracture(OR-0.921,0.808,2.684,17.762,0.808,2.684,17.762;95％CI were 0.797-0.819,0.914-0.927,2.215-3.254,14.317-22.037)(P＜0.05).Conclusion:The incidence rate of patients with tibial shaft fracture complicated with occulted posterior mal-leolar fracture was 35.00％.The distance from the lowest fracture line to the tibia-distal articular surface,the length of the tibial fracture line,non-spiral fracture and distal fracture were the related factors.
