Radiographic analysis in reduction loss and parameters maintenance after distal radius fracture fixation with variable-angle volar locking plate
摘要
Background: Reduction loss is commonly seen in the treatment of distal radius fractures and remains a critical issue even in using newly designed locking plates. Purpose: The purpose of this study is to investigate the efficacy of the variable-angle volar locking plate (VAVLP) in maintenance of fracture fixation. Methods: A total of 37 patients with unilateral distal radius fractures receiving VAVLP fixation were included. Those having forearm radiographs immediately after surgery for 3 months were retrospectively reviewed, and radiographic parameters including radial height (RH), ulnar variance (UV), radial inclination (RI), volar tilt (VT), tear drop angle (TDA), distal dorsal cortical distance (DDD), and Soong classification (SC) were analyzed. Results: By comparing the 3-month measurement with normal data, the difference of RH/UV/TDA was significant (p-value ＜ 0.001) while the difference of RI/VT was insignificant. However, there was no significant difference regarding those five parameters between postoperative and 3-month measurement. Linear regression on DDD exhibited positive dependence with the p-value of 0.002 between postoperative and 3-month changes. Postoperative SC was graded 0 in 13 patients, graded 1 in 21 patients, and graded 2 in 3 patients. There were 6 patients of grade 0 and 2 patients of grade 1 showing one-grade change. Conclusions: VAVLP fixation in distal radius fracture can maintain radiographic alignment till fracture union. Radiographic parameters could be obtained in normal range for RI and VT, but not for RH, UV, or TDA.
