Comparative analysis of clinical outcomes of fixed-angle versus variable-angle locking compression plate for the treatment of Lisfranc injuries

초록

Background: Fixed-angle locking compression plate (LCP) and variable-angle LCP are utilized for internal fixation of Lisfranc injuries. However, studies regarding the difference of clinical outcomes of these two plates are limited. The purpose of present study was to compare postoperative outcomes between these two plate types in Lisfranc injuries. Methods: A total of 45 consecutive patients (22 patients with fixed-angle LCP and 23 patients with variable-angle LCP) who underwent surgical treatment for Lisfranc injury were reviewed for this retrospective study. The Foot Function Index (FFI), numerical rating scale (NRS) for pain, development of complications, operative time, and patient satisfaction for current activity were compared. Results: There were no significant differences in FFI and NRS for pain at three months and 12 months following surgery. Postoperative complication rate was similar between two groups. Patients with variable-angle LCP had an 18 min shorter mean length of operation (p = 0.040). Patient satisfaction for current activity was not differ between two groups. Conclusions: The use of variable-angle LCP for treatment of Lisfranc injuries did not show superiority in functional outcomes, pain, complication rates, or patient satisfaction to fixed-angle LCP, but operative time was shorter with variable-angle LCP. Level of Evidence: Level III, retrospective comparative study. (c) 2019 Published by Elsevier Ltd on behalf of European Foot and Ankle Society.
