Abstract:【Objective】To investigate the clinical effect of minimally invasive plate internal fixation with three-point Kirschner wire and preservation of pronator muscle in the treatment of distal radius fractures.【Methods】A total of 118 patients with distal radius fractures treated in Qishan County Hospital from July 2018 to July 2021 were selected and divided into control group and observation group according to different treatment methods, with 59 cases in each group. The control group was treated with conventional minimally invasive plate internal fixation with preservation of pronator muscle, and the observation group was treated with minimally invasive plate internal fixation with preservation of pronator muscle by three-point positioning of Kirschner wire. The perioperative indexes (operation time, intraoperative bleeding, number of times of anterior pronator submuscular plate adjustment, incision length) and the clinical effect of 3 months after operation were observed. The wrist range of motion, wrist function (Gartland Werley score), upper limb function (DASH score) and complications were compared and observed between the two groups at 3 months after operation. 【Results】There was no significant difference between the two groups in operation time, intraoperative bleeding, incision length and excellent rate of treatment effect (P>0.05); The number of adjustment and release of pronator submuscular plate in the observation group was less than that in the control group (P<0.05); Three months after operation, the pronation angle and radial deviation angle in the observation group were greater than those in the control group (P<0.05); At 1 and 3 months after operation, the Gartland Werley and DASH scores in the observation group were lower than those in the control group (P<0.05); There was no significant difference in the incidence of complications between the two groups (P>0.05). 【Conclusion】Kirschner wire three-point positioning and minimally invasive plate internal fixation with preservation of pronator muscle in the treatment of distal radius fractures can reduce the number of adjustment and placement of pronator muscle plate, improve wrist range of motion, improve wrist function and upper limb function, and has high safety, which is worthy of clinical application.
