Comparison of the therapeutic effects of two kinds of internal fixation for distal radial fractures

Abstract

Objective To compare therapeutic effects of oblique T-locking compression plate system (LCP) and general AO T-plate and screw system for treatment of distal radius fractures. Methods From March 1999 to December 2009, 313 cases of distal radial fractures were treated with LCP or AO T-plate and screw system in our department, were follow-up. Postoperative functional score were performed by Sarmiento modified Gartland-Werley scoring system (GW score) was used to assess the postoperative functions in 72 (73 wrists) cases with complete follow-up. Wrist joint function was compared between patients who underwent LCP fixation (LCP group) and patients who underwent AO T-plate and screw system fixation (routine group).Results Tne follow-up time was 3 months to 6 years, with an average of 25.4 months. Bone union was seen in X-rays of all cases. The average score of the LCP group was 1.98 points, and the AO T-plate and screw system group was 1.43 points. There was no significant difference between the two groups ( P > 0.05), and the differences of patient satisfaction between the two group were not notable either ( P > 0.05). Conclusion AO T- plate and screw system is suitable for majority of type A fractures with failed manipulative reduction, type B fractures with obvious displacement, and type C fractures. LCP fixation is more reliable for type C comminuted fractures with osteoporosis.
