Abstract
目的 研究锁定加压钢板治疗累及桡骨远端粉碎性骨折的效果.方法 26例桡骨远端骨折,平均年龄61岁.按照AO骨折分型:C1型8例;C2型12例;C3型6例.其中2例为开放性骨折,另2例分别合并肩与肘关节脱位.均采用掌侧入路,T型锁定钢板固定.结果 26例术后随访6~20个月,平均8个月.骨折平均愈合时间为8周(6~12周).腕关节活动度平均为:掌屈40°,背伸45°,尺偏30°,桡偏20°,旋前70°,旋后65°.最近1次随访X线片与术前相比,桡骨茎突平均长度自术前6 (-10~10)mm增加至11(8~14)mm.平均掌倾角自术前-15°(-40°~10°)增加至8°(-5°~15°).平均尺偏角从12°(-5°~20°)增加至20°(10°~25°).关节面骨折块平均间距从6(1~18)mm减少至0(0~3)mm.术侧握力为健侧的 78%(55%~100%).根据Gartland与Werley评分标准,优7例,良12例,一般5例,差2例.结论对于累及关节面的粉碎性桡骨远端骨折,T型锁定钢板可以较好地维持骨折复位,允许术后早期功能锻炼,并可获得满意的腕关节功能。
