AbstractIn a prospective, randomized study, 30 patients were evaluated after ankle fracture treated by means of open reduction and internal fixation. The patients were randomized to either postoperative immobilization in a plaster cast for 6 weeks or early mobilization (1-2 weeks after surgery) in an ankle brace. Both regimens allowed weightbearing. Evaluation after 10 weeks and after 12 months included clinical assessment and isokinetic muscle strength measurements. Patients with impaired ankle function, as shown by means of an ankle score at 12 months, were followed for 3 years. At 10 weeks, impaired muscle torque and restricted range of motion was found on the affected side. This impairment was significantly less in the brace group. At 12 months, range of motion of the ankle and subtalar joints was restored, but dorsiflexion was still better in the brace group. Score values from a functional score did not correlate with muscle strength.
