T-type comparison of locking compression plate versus variable angle locking compression plate in treatment of distal radial fractures

Objective To compare the clinical effects of the T-type volar locking compression plate and variable angle two-column locking compression plate in treatment of 118 cases with distal radial fractures. Methods Retrospectivly analyzed the clinical data of distal radius fracture cases from Dec. 2011 to Nov. 2015 in Department of Orthopedics, Beijing Friendship Hospital, Capital Medical University who were respectively underwent T-type locking compression plate and variable angle two-column locking compression plate. The T-type locking compression plate group of 60 cases; according to AO/OTA classification, including 3 cases of type A3, type B2 5 cases, type B3 7 cases, type C1 10 cases, type C2 20 cases, type C3 in 15 cases. The variable angle two-column locking compression plate variable angle two-column locking compression plate group 58 cases; according to AO/OTA classification, including 1 cases of type A3, type B2 2 cases, type B3 4 cases, type C1 15 cases, type C2 18 cases, type C3 18 cases. Comparative analysis of two groups of postoperative radiographic parameters and functional recovery. Palm angle, ulnar deviation angle, radius height, wrist joint activity and G-W function score were measured by (±s), and the comparison was performed t test. Results All patients were followed up, mean follow-up time of T-type locking compression plate group was 26.5 months, the mean follow-up time of variable angle two-column locking compression plate group was 25.6 months. The results showed that there were no significant differences between the two groups in ulnar deviation angle, radius height, radial deviation angle and Gartland-Werley function score.There was significant difference between the two groups in the angle of palm angle, wrist dorsal extension, palmar flexion, ulnar deviation, Wrist rotation, and variable angle two-column locking compression plate had advantages. Conclusion Two kinds of treatment of distal radius fractures were satisfactory clinical efficacy, and variable angle two-column locking compression plate had more advantages, doctors can choose corresponding fixation methods according to the specific situation of patients.
