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

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.

Metallosis after Revision of a Fractured Ceramic Head onto a Metal-on-Polyethylene Articulation: A Case Report / 대한정형외과학회잡지

A ceramic articulation thought to be superior to metal-on-polyethylene due to its extremely low coefficient of friction and its potential for resistance to wear. But ceramic is brittle, which makes it theoretically susceptible to fracture. Although many authors have reported that metal-on-polyethylene articular pairing had good results after a ceramic head fracture, there have been few reports about complication due to the remaining ceramic particles after revision surgery. We report here on a case of severe metallosis that was thought to be due to third body wear by the remaining fractured ceramic particles after revision total hip arthroplasty.
