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.
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。
