Abstract

Abstract: Based on multi-slice spiral CT this study evaluated the changes of lower limb alignment and its relationship with knee joint function after internal fixation of tibial plateau fractures. The clinical data of 125 patients with tibial plateau fractures treated with internal fixation were retrospectively analyzed. Compared the posterior tilt angle of tibial plateau (PA), tilt angle of tibial plateau (TPA), femoro tibia angle (FTA), knee joint space width and platform collapse between the affected side and the healthy side 3 days after operation. Compared the changes of PA, TPA, FTA, knee joint space width and platform collapse on the affected side at different times after surgery. And then compared the differences between the affected side and the healthy side of PA, TPA, FTA, knee joint gap width, and platform collapse in patients with joint function. The results showed that the PA, TPA, knee joint space width difference and platform collapse between the affected side and the healthy side in patients with excellent, good and fair + poor knee function increased in sequence at 6 months after operation (P<0.05). The difference of PA, TPA, knee joint space width and platform collapse between the affected side and the healthy side were negatively correlated with knee joint function (P<0.05). It can be seen that multi-slice spiral CT can accurately evaluate the changes of lower limb alignment after internal fixation of tibial plateau fractures. Among them, PA, TPA, knee joint space width and platform collapse are related to postoperative knee joint function.

Key words: multi-slice spiral CT, tibial plateau fractures, after internal fixation, lower limb alignment, knee joint function
