Clinical and functional outcomes of Lambrinudi arthrodesis for correcting fixed equinus deformity

Objective: To evaluate the clinical and functional outcomes of correction of fixed equinus deformity by Lambrinudi arthrodesis. Methods: Eight patients with fixed equinus deformity were retrospectively assessed. Of these patients, three cases developed secondary to Charcot-Marie-Tooth disease, and five cases developed secondary to fibular nerve injury following trauma. All patients underwent Lambrinudi arthrodesis using the open technique, and functional improvement was analysed postoperatively. The mean age of the patients was 27 years and six months, and six patients were men. Results: The results were evaluated using the ankle and hindfoot score of the American Orthopedic Foot and Ankle Society (AOFAS) scale. The mean score in the postoperative period was 61.71 points, ranging from 41 to 74 points. The difference in the tibia-ground angle in the pre- and postoperative period was measured, and there was a significant correction of this angle. Conclusion: The outcomes of Lambrinudi arthrodesis in patients with fixed equinus deformity were satisfactory concerning the improvement of pain, gait, a high degree of correction of the deformity according to the difference in the tibia-ground angle between the pre- and postoperative period, and preservation of the ankle joint.
