The use of volar locking plate fixation (VLP) for unstable extra-articular distal radial fractures has increased in the last decades. External fixation (EF) is less frequently used. This change of surgical approach has only to some extent been evidence-based.
In this multicenter, randomized controlled trial, we compared VLP and EF in patients between 18 and 70 years of age who had a displaced extra-articular distal radial fracture (OTA/AO type A3). The patients were examined at 6 weeks, 3 months, and 1 year postoperatively. The primary outcome measure was the Patient-Rated Wrist/Hand Evaluation score (PRWHE). Secondary outcomes were the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), pain score on a visual analog scale (VAS), and radiographic measurements. Range of motion, grip strength, finger stiffness, complications, and reoperations were also recorded.
One hundred and fifty-six patients were included. One hundred and forty-two (91%)-127 women (89%) and 15 men (11%)-completed 1 year of follow-up. Sixty-nine patients were treated with VLP and 73, with EF. The mean age was 56 years. At 6 weeks, the median PRWHE score was significantly higher in the EF group (44) compared with the VLP group (27) (p < 0.001). At 3 months and 1 year, the difference between groups was not significant. The median QuickDASH score was 27 in the VLP group and 43 in the EF group at 6 weeks (p < 0.001), and a significant difference persisted at 3 months (p = 0.023). The VLP group had superior results in terms pain during activity, wrist extension, and ulnar and radial deviation at 1 year, whereas the number of major complications was similar in the 2 groups.
Patients treated with VLP had earlier recovery of function compared with patients treated with EF. One year postoperatively, we found no significant functional difference.

在过去几十年中,掌侧锁定钢板固定(VLP)在不稳定的关节外桡骨远端骨折中的应用有所增加。外固定(EF)的使用则较少。这种手术方法的改变在某种程度上还没有得到充分的证据支持。
在这项多中心、随机对照试验中,我们比较了 VLP 和 EF 在 18 至 70 岁、有移位的关节外桡骨远端骨折(OTA/AO 型 A3)的患者中的应用。患者在术后 6 周、3 个月和 1 年进行检查。主要观察指标是患者腕/手评估评分(PRWHE)。次要观察指标是手臂、肩部和手残疾的简化版(QuickDASH)、视觉模拟评分法(VAS)疼痛评分和影像学测量。还记录了活动范围、握力、手指僵硬、并发症和再次手术的情况。
共纳入 156 例患者。142 例(91%)-127 例女性(89%)和 15 例男性(11%)-完成了 1 年的随访。69 例患者接受 VLP 治疗,73 例患者接受 EF 治疗。平均年龄为 56 岁。在 6 周时,EF 组的 PRWHE 评分中位数(44)明显高于 VLP 组(27)(p < 0.001)。在 3 个月和 1 年时,两组之间的差异无统计学意义。VLP 组的 QuickDASH 评分中位数为 27 分,EF 组为 43 分,6 周时差异显著(p < 0.001),3 个月时仍有显著差异(p = 0.023)。VLP 组在活动时疼痛、腕伸、尺偏和桡偏方面的结果在 1 年时更优,而两组的主要并发症数量相似。
与 EF 治疗的患者相比,VLP 治疗的患者功能恢复更早。术后 1 年,我们没有发现功能上的显著差异。
