Use of Foot Correction Exerciser for Rehabilitation Following External Fixation in High-Energy Pilon Fracture.

Objective: Our aim was to study the clinical effect of a foot correction exerciser used for postoperative rehabilitation in external fixation in high-energy Pilon fracture.

Methods: From March 2017 to November 2019, 43 patients with AO/OTA type C closed Pilon fractures treated with external fixation were retrospectively analyzed. A total of 23 patients were rehabilitated by foot correction exerciser (1 patient fell off the study), and 20 patients were treated by conventional rehabilitation (2 patients fell off the study). During postoperative hospitalization and regular follow-up after discharge, various indicators were recorded for statistical comparison and evaluation through angle measurement, imaging and questionnaire surveys.

Results: There was no significant difference in postoperative complications in the 2 groups (P > .05). The fracture healing time and stent wearing time in the study group were shorter than in the control group, and the comfort score and functional exercise compliance were higher in the study group than in the control group. The ankle joint mobility was higher in the study group than in the control group at all time points in the first 6 months, and the excellent and good rate of ankle joint function was higher than in the control group, with statistical significance (P < .05).

Conclusion: Use of the orthopedic exerciser in the high-energy Pilon fracture external fixation postoperative rehabilitation process and the early introduction of resistance training can reduce pain and soft tissue edema and improve the degree of patient comfort and exercise compliance, accurately measure the force load of the limbs, contribute to the dataization and standardization of rehabilitation exercise programs, accelerate the recovery of joint mobility and improve long-term limb function.
