| Summary: | Purpose: To investigate efficacy of open reduction and internal fixation with the miniplate and hollow screw in the treatment of Lisfranc injury.
Methods: Ten cases of Lisfranc injury treated by open reduction, miniplate and hollow screw in our hospital were retrospectively analyzed. There were 6 males and 4 females with age ranging from 25 to 45 years (mean 32 years). Among them, one case was classified as Type A, six Type B and three Type C. Injury mechanism included road traffic accidents (3 cases), fall from height (5 cases) and hit by heavy
object (2 cases). All injuries were closed without cerebral trauma or other complicated injuries. The time interval between injury and operation was 6e10 days (average 6.6 days). Postoperatively, the foot function was assessed using Visual Analogue Scales (VAS) and American Orthopaedic Foot and Ankle
Society (AOFAS) Scales. Healing time and complications were observed.
Results: All patients were followed up for 18e24 months (average 20 months). Anatomic reduction was achieved in all patients on images. There was statistical significance between preoperative score
(7.89 ± 0.34) and score at postoperative 8 weeks (0.67 ± 0.13). According to the AOFAS score, 5 cases were defined as excellent, 3 cases as good and 2 cases as fair. During follow-up, there was no wound infection
or complications except for osteoarthritis in 2 cases. Healing time ranged from 3 to 6 months with an average of 3.6 months.
Conclusion: Anatomical reduction of Lisfranc injury can be achieved by open reduction and internal fixation with the miniplate and hollow screw. Normal structure of Lisfranc joint is regained to a great
extent; injured ligaments were also repaired. Therefore, this method offers excellent curative effect and can avoid postoperative complications and improve the patients' quality of life.
