The purpose of this study was to evaluate the clinical performances of stainless steel nonlocking plates and titanium locking plates in minimally invasive medial plating of extra-articular metaphyseal fractures of the distal tibia.
Between 2004 and 2006, 43 patients who sustained closed fractures of the distal tibia metaphysis were managed with either a stainless steel nonlocking plate (Group 1, n = 21) or a titanium locking plate (Group 2, n = 22). Clinical and radiographic data were retrospectively reviewed. Function was assessed with use of the American Orthopaedic Foot and Ankle Society ankle-hindfoot instrument. The average followup period was 25 months.
The average AOFAS foot and ankle scores in Group 1 and Group 2 at final followup were 85 and 81, respectively. Fracture reduction was anatomical or nearly anatomical without angular displacement in all cases except one patient in Group 2. (p > 0.05) The average time to full, unprotected weightbearing in Group 1 and Group 2 were 15 weeks and 18 weeks, respectively (p < 0.05).
Minimally invasive medial plating with titanium locking plates resulted in prolonged secondary healing both in comminuted and simple fracture patterns compared to conventional stainless steel nonlocking plates. We believe that in biological fixation of distal tibial fractures, similarly good results may be obtained with both materials as the locking technology had a greater effect on stability.
本研究旨在评估不锈钢非锁定板和钛锁定板在微创经皮内固定治疗胫骨远端干骺端关节外骨折的临床效果。
2004 年至 2006 年，我们采用不锈钢非锁定板（A 组，n = 21）或钛锁定板（B 组，n = 22）治疗 43 例胫骨远端干骺端闭合骨折患者。回顾性分析临床和影像学资料。采用美国矫形足踝协会踝-后足评分系统评估功能。平均随访 25 个月。
末次随访时 A 组和 B 组的 AOFAS 踝与后足评分分别为 85 分和 81 分。除 1 例 B 组患者存在角度移位外，所有患者的骨折复位均为解剖或近乎解剖。（p > 0.05）A 组和 B 组患者完全负重的平均时间分别为 15 周和 18 周（p < 0.05）。
与传统的不锈钢非锁定板相比，钛锁定板微创经皮内固定治疗胫骨远端粉碎性和简单骨折，会导致二期愈合时间延长。我们认为，在胫骨远端骨折的生物学固定中，两种材料可能都能获得同样良好的效果，因为锁定技术对稳定性的影响更大。
