Comparison of Outcomes for Unstable Distal Radius Intraarticular Fractures: T-locking Compression Plate versus External Fixator

ABSTRACT

PURPOSE: To compare the outcomes between T-locking compression plate (T-LCP) and external fixator (EF) for unstable distal radius intraarticular fractures. MATERIALS AND METHODS: We retrospectively analysed the results in 22 cases with T-LCP, 20 cases with EF. We evaluated the clinical results according to the Mayo Wrist Scoring System, radiographic results. RESULTS: The mean score was 84.6 in the T-LCP group and 80.5 in the EF group respectively. Final radiographic measurements for the T-LCP group averaged 10.5 mm radial length, 21.7degrees radial inclination, 9.8degrees volar tilt and 0.25 mm intraarticular step-off. The EF group averaged 10.1 mm radial length, 20.3 degrees radial inclination, 6.3 degrees volar tilt and 0.73 mm intraarticular step-off. CONCLUSION: Both groups showed satisfactory final clinical outcomes. But T-LCP group allowed return to daily living, resulting in early postsurgical wrist motion. By the anatomical reduction, final volar tilt, intraarticular step-off were statistically better in the T-LCP group.
