RESUMEN
Lisfranc joint dislocation secondary to Charcot arthropathy is a debilitating condition that often leads to ulceration and infection. After conservative treatment, such as bracing and appropriate shoe wear fail, the only option might be amputation. However, we have seen good clinical outcomes from applying a plate to the plantar (tension) side of the medial midfoot. In our retrospective study, 24 consecutive patients (25 feet) from April 1999 through July 2004 underwent Charcot reconstruction for Lisfranc dislocation. Clinical and radiographic follow-up examinations were performed every 3 weeks during the postoperative course. Union was achieved in 24 (96%) of the 25 feet. The average time to ambulation was 11.68 (range 7 to 20) weeks for the 24 patients. The average follow-up period was 38.0 (range 17 to 64) months. The union and interval to ambulation rates showed that a plate applied to the plantar aspect of the medial midfoot provides a strong, sturdy construct for arthrodesis and ambulation.
