[Short-term results of open reduction and percutaneous Kirschner wire fixation for Chopart joint dislocation].

OBJECTIVE
To investigate short-term clinical efficacy of open reduction and percutaneous Kirschner wire fixation for Chopart joint dislocation.


METHODS
From August 2014 to August 2017, 13 patients with Chopart joint dislocation were treated by open reduction and percutaneous Kirschner wire fixation, including 7 males and 6 female aged from 13 to 58 years old. American Orthopaedic Foot and Ankle Society(AOFAS)criteria system and visual analogue scale (VAS) were applied to evaluate function of foot and ankle at 12 months after operation.


RESULTS
All patients were followed up from 8 to 24 months. AOFAS score at 12 months after operation ranged from 65 to 99; 8 cases got excellent results, 4 good and 1 moderate. VAS score ranged from 0 to 4. All wounds were primary healed from 12 to 16 days, and no skin necrosis, infection, Kirschner broken, or other complications occurred. One patient occurred Kirschner's wire loosening at 4 weeks after operation.


CONCLUSIONS
Open reduction and percutaneous Kirschner wire fixation for Chopart joint dislocation could relieve pain and improve functional activities and obtain satisfactory short-term clinical results.
