改良后外侧入路内固定术对踝关节骨折患者的应用效果及踝关节活动度的影响

Objective To observe the application effect of the modified posterolateral internal fixation on patients with ankle fractures and its influence on ankle joint range of motion. Methods The research subjects were 60 patients with ankle fractures admitted to our hospital from January 2023 to December 2025. The subjects were randomly divided into two groups, with 30 cases in each group. The control group was treated with the traditional posterior lateral approach internal fixation, while the observation group was treated with the modified posterolateral internal fixation. The treatment effects, ankle joint range of motion, surgical-related indicators, pain degree, and joint function of the two groups were compared. Results Compared with the control group, excellent and good rate of the observation group was higher, the ankle joint dorsiflexion, plantar flexion, inversion, and eversion range of motion after treatment was greater, the operation time, intraoperative blood loss, and hospital stay were shorter, the VAS score after treatment was lower, the AOFAS score was higher, P<0.05. Conclusion The modified posterolateral internal fixation for ankle fractures can effectively improve the treatment effect, improve the ankle joint range of motion, optimize surgical-related indicators, relieve pain, and promote joint function recovery. The clinical application value is significant.
