Abstract：Objective To investigate the effect of 3D-printed guide plate assisted plate fixation on the accuracy of ankle fracture surgery and postoperative ankle function.Methods A retrospective analysis was performed on the clinical data of 82 patients with ankle fractures admitted to the hospital from December 2020 to December 2023.According to the surgical method,patients were divided into the plate group(plate fixation,43 cases)and the 3D-printed guide plate group(3D-printed guide plate assisted plate fixation,39 cases).The two groups were compared by perioperative indicators,surgical accuracy,postoperative ankle dorsiflexion and plantarflexion angles,and ankle function.The incidence of postoperative adverse reaction was recorded.Results Surgery time of the 3D-printed guide plate group and the plate group was(88.00±28.62)min and(107.30±32.60)min(t=2.837,P=0.006).The excellent and good rates of the fracture reduction in the 3D-printed guide plate group and the plate group were 92.31%and 88.37%,without statistically significant difference(χ2=0.052,P=0.820).Ankle dorsiflexion angles in the 3D-printed guide plate group and the plate group at 3 months after surgery were(15.64±1.56)° and(13.81±1.62)°(t=2.199,P=0.000).Ankle dorsiflexion angles at 6 months after surgery were(17.79±1.67)° and(16.02±1.64)°(t=4.839,P=0.000).Plantar flexion angles in the 3D-printed guide plate group and the plate group at 3 months after surgery were(42.74±1.77)° and(40.53±1.84)°(t=5.531,P=0.000).Plantar flexion angles at 6 months after surgery were(50.74±1.66)° and(48.81±1.68)°(t=5.225,P=0.000).AOFAS scores of the 3D-printed guide plate group and the plate group at 3 months after surgery were(68.46±4.17)and(65.28±4.65)(t=3.247,P=0.002).AOFAS scores at 6 months after surgery were(89.56±4.63)and(86.63±7.28)(t=2.149,P=0.035).The incidence rates of adverse reactions such as skin numbness and traumatic arthritis in the two groups after surgery were close(P>0.05).Conclusions 3D-printed guide plate assisted plate fixation can shorten surgery time and promote postoperative ankle function recovery for patients with ankle fracture.
