RESUMO
The preliminary results of early functional treatment of 30 patients with a grade-II supination-eversion fracture of the ankle according to Lauge-Hansen are discussed. The treatment of all patients consisted of splint immobilization for one week, followed by the application of a functional brace (Push Brace Medium) and immediate full weight bearing and functional training. All fractures healed without complications. Ankle function, radiographic findings and anamnestic complaints were monitored. The loss of ankle function diminished to 3.2 degrees +/- 4.9 degrees plantar flexion and to 1.7 degrees +/- 5.3 degrees dorsal flexion after one year follow up, none of the patients had significant complaints of pain or swelling. Radiography showed consolidation with callus formation in all cases. The grade-II supination-eversion fracture is a stable fracture which allows early functional treatment with the support of a Push Brace Medium. This results in an inexpensive, simple and comfortable therapy. A prospective randomized clinical trial is necessary to show the advantages of functional treatment over cast immobilization. Long-term follow-up will have to ascertain the theoretic risk of posttraumatic osteo-arthritis.
