ObjectiveTo explore the efficacy of minimally invasive anatomical locking plate combined with appositional screws in the treatment of distal tibia and fibula fractures. MethodsForty-six patients with distal tibia and fibula fractures were divided into observation group (n=21) and control group (n=25) according to the treatment. The observation group and the control group underwent minimally invasive anatomical locking plate combined with the appositional screw and simple minimally invasive anatomical locking plate respectively. The related indices were recorded, including duration for radiological healing and clinical healing, six-month healing rate, Johner-Wruhs score of affected limb function and complications. ResultsAll the patients were followed up for 9-34 months.The duration for radiological and clinical healing in the observation group ［(46.57±14.51) d and (86.27±19.35)d respectively］ were significantly shorter than those of the control group ［(61.18±18.25)d and (112.84±24.46)d respectively］ (P＜0.05).There was no significant difference in the six-month healing rate between the observation group and the control group (5.24% vs. 84%, P＞0.05). There was no significant difference in the excellent and good rate of Johner-Wruhs function for affected limbs between the observation group and the control group (85.71% vs. 80%, P＞0.05).There was no significant difference in the incident rate of complications between the observation group and the control group (23.81% vs. 16%, P＞0.05). ConclusionFor distal tibia and fibula fracture, minimally invasive anatomical locking plate combined with appositional screws is safe, can promote fracture healing, and is worthy of clinical promotion and application.
