Locking and non-locking plates has been used for distal tibia fracture osteosynthesis. Sufficient evidence to favor one implant over the other is lacking in the current literature. Our aim is to compare them in terms of fracture healing, alignment, functional outcome, complications.
Sixty-eight patients operated on using a percutaneous plate were retrospectively reviewed. They were divided into two groups: in group 1 (28 patients) a 4.5mm narrow conventional dynamic compression plate (DCP) was used. In group 2 (40 patients) a titanium locked compression plate (LCP) was used.
Mean time to union was 16.2 and 15.4 weeks for group 1 and 2, respectively (p=0.618). 11 patients (39.3%) in group 1 and 4 patients (10%) in group 2 showed malalignment (p=0.016). AOFAS scores at follow up were 89 and 88 in groups 1 and 2, respectively. Implant removal was necessary in 9 cases (32.1%) and 4 cases (10%) in group 1 and group 2, respectively (p=0.042). Three patients (10.7%) in group 1 and three patients (7.5%) in group 2 had an infection.
Both plating systems have similar results in terms of time to union, infection, and AOFAS scores. The LCP seems superior with respect to alignment and the need for implant removal.
锁定钢板和非锁定钢板已被用于胫骨远端骨折的内固定。目前的文献中缺乏一种植入物优于另一种植入物的充分证据。我们的目的是比较它们在骨折愈合、对线、功能结果和并发症方面的情况。
回顾性分析了 68 例经皮钢板手术的患者。他们被分为两组：组 1（28 例）使用 4.5mm 窄常规动力加压钢板（DCP），组 2（40 例）使用钛锁定加压钢板（LCP）。
组 1 和组 2 的平均愈合时间分别为 16.2 周和 15.4 周（p=0.618）。组 1 中有 11 例（39.3%）和组 2 中有 4 例（10%）出现对线不良（p=0.016）。组 1 和组 2 的 AOFAS 评分分别为 89 和 88。组 1 中有 9 例（32.1%）和组 2 中有 4 例（10%）需要取出内固定物（p=0.042）。组 1 中有 3 例（10.7%）和组 2 中有 3 例（7.5%）发生感染。
两种钢板系统在愈合时间、感染和 AOFAS 评分方面的结果相似。LCP 在对线和需要取出内固定物方面似乎更有优势。
