OBJECTIVETo study the clinical results of surgical treatment for Lisfranc fracture-dislocation.

METHODSFrom January 2003 to September 2009, 57 patients with Lisfranc injuries were treated by surgical operation included 41 males and 16 females with an average age of 33.8 years old ranging from 20 to 64 years. According to Myerson's classification, there were 31 cases of middle column injuries, 15 cases of medial-middle column injuries and 11 cases of three-column injuries. Among them, 25 patients accepted the emergency operation (<24 hours) and 32 patients were treated in average 7 days (3 to 11 days) after injury.

RESULTSAll the wounds were healed primarily with a mean operative time of 50 min (30 to 70 min). All patients were followed up for 4 to 70 months (averaged 35 months). The total AOFAS scores (American Orthopaedic Foot and Ankle Society) was in averaged of(84.73 +/- 14.26). All the patients returned to normal daily life after a mean time of 5.1 months (3 to 12 months). The average AOFAS scores of 52 anatomical reduction cases was (87.63 +/- 13.71), 5 non-anatomical reduction cases was (74.31 +/- 21.96), 26 multiple column trauma cases was (76.58 +/- 11.51). Complications of osteoarthritis occurred in 8 cases, confirming it was the main complication of these injuries.

CONCLUSIONLisfranc injuries can be surgically treated well. Reduction of the middle column is the key to reestablishment the stability of the tarsometatarsal joint complex. The quality of the reduction correlated with treatment outcome.
