[Curative effect analysis of surgical treatment of Lisfranc joint injuries].

OBJECTIVE

To investigate the clinical results and influence factors in surgical treatment of the Lisfranc joint injury.

METHODS

From Jan. 2009 to Nov. 2011 ,13 patients (14 feet) with Lisfranc joiat injury received open reduction and screw or wire or external fixation including 9 males and 4 females with an average age of 42 years old ranging from 18 to 61 years. According to the Myerson classification,there were 1 case of type A, 9 of type B and 4 of type C. All the patients received open reduction and internal (1 with external) fixation with screw or Kirschner wire within 22 days after injury. The postoperative function was estimated by mid-foot scoring scale of AOFAS. X-ray were used in radiography estimation.

RESULTS

All the patients were followed up for 5 to 30 months (averaged 20 months). According to mid-foot scoring scale of AOFAS,there were 8 feet with excellent results,4 with good and 2 with fair results. The anatomical reduction was observed in 12 feet and all the patients obtained bony union according to the results of X-ray.

CONCLUSION

Open reduction and internal fixation is a good choice for the treatment of Lisfranc joint injury. A preoperative estimate,proper reduction during operation and maintainence after operation may influence the clinical results.
