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.
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.
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.
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.
用于桡骨远端骨折固定的掌侧锁定钢板的取出率较高，且存在肌腱断裂风险。钢板设计对并发症发生率有影响。本研究评估了常用于治疗桡骨远端骨折的Acu-Loc 2掌侧远端桡骨（VDR）钢板的取出率和肌腱断裂率。
我们在电子医疗记录系统中搜索了2017年1月至2021年12月期间在三级中心接受Acu-Loc 2 VDR钢板（美国俄勒冈州希尔斯伯勒市Acumed公司生产）固定治疗的所有患者。如果患者的随访时间少于一年或无法通过电话随访联系到，则将其排除。术前X线片用于骨折分类。随访时间定义为在诊所或通过电话的最后一次联系时间。
共有92例患者接受了Acu-Loc 2 VDR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，60例骨折（69.0%）为关节内骨折。患者的平均随访时间为593.3天（范围为369至1185天）。4例患者（4.7%）取出了内固定物。3例患者（3.5%）因肌腱刺激而取出，1例患者（1.2%）因钢板周围假体周围骨折而取出。未记录到肌腱断裂情况。
Acu-Loc 2 VDR钢板的中期取出率较低，且无肌腱断裂情况。与其他远端钢板设计相比，这些发生率较低。
