Abstract：
OBJECTIVE: Volar locking plates designed for far distal radius fracture fixation can have a significant hardware removal rate and risk of tendon rupture. Plate design has a role in the rate of complications. This study assessed the hardware removal and tendon rupture rate of the Acu-Loc 2 volar distal radius (VDR) plate often used in the treatment of far distal radial fractures.
METHODS: We searched our electronic healthcare records system for all patients who had undergone fixation with an Acu-Loc 2 VDR plate (Acumed, Hillsboro, OR, USA) at a tertiary center between January 2017 and December 2021. Patients were excluded if their follow-up time was less than one year or if they could not be contacted by telephone follow-up. Pre-operative radiographs were examined for fracture classification. Follow-up time was defined as the last contact in the clinic or by telephone.
RESULTS: A total of 92 patients underwent an open reduction and internal fixation (ORIF) with an Acu-Loc 2 VDR plate. A total of 85 patients met the inclusion criteria for this study. Our cohort included 33 males (38.8%) and 52 females (61.2%). The mean age was 50 years. Twenty-seven fractures (31.0%) were extra-articular, and 60 fractures (69.0%) were intra-articular. The mean follow-up time for the patients was 593.3 days (range 369 to 1185 days). Four patients (4.7%) had their hardware removed. Three (3.5%) patients underwent removal due to tendon irritation and one patient (1.2%) due to a peri-prosthetic fracture around the plate. There were no tendon ruptures recorded.
CONCLUSIONS: The Acu-Loc 2 VDR plate had a low medium-term hardware removal rate and no tendon ruptures. These rates are lower than would be expected when compared with other far distal plate designs.

摘要：
目的：设计用于桡骨远端骨折固定的掌侧锁定钢板可以具有显着的硬件去除率和肌腱断裂的风险。钢板设计对并发症的发生率有一定的影响。这项研究评估了经常用于治疗桡骨远端骨折的Acu-Loc2掌骨远端（VDR）钢板的硬件去除和肌腱断裂率。
方法：我们搜索了我们的电子医疗记录系统中所有使用Acu-Loc2VDR钢板固定的患者（Accumed，希尔斯伯勒,OR,美国）在2017年1月至2021年12月之间处于三级中心。如果患者的随访时间少于一年或无法通过电话随访联系，则将其排除在外。术前X线片检查骨折分类。随访时间定义为最后一次在诊所或通过电话联系。
结果：共有92例患者接受了Acu-Loc2VDR钢板切开复位内固定术（ORIF）。共有85例患者符合本研究的纳入标准。我们的队列包括33名男性（38.8%）和52名女性（61.2%）。平均年龄为50岁。27例骨折（31.0%）为关节外骨折，关节内骨折60例（69.0％）。患者的平均随访时间为593.3天（范围为369至1185天）。四名患者（4.7％）的硬件被移除。三名（3.5％）患者由于肌腱刺激而被切除，一名患者（1.2％）由于钢板周围的假体周围骨折而被切除。没有记录到肌腱断裂。
结论：Acu-Loc2VDR板的中期硬件去除率较低，没有肌腱断裂。当与其他远端的板设计相比时,这些速率低于预期。
