The aim of this study was to analyse and compare the 24-month range of motion results of patients treated with CFR-PEEK2 versus conventional titanium plate osteosyntheses (TAL-P). We hypothesized similar clinical outcomes but a better range of motion in the CFR-PEEK2 group than the TAL-P group in the 2-year follow-up.
This retrospective study analysing prospectively collected data included all patients that presented with a PHF and were treated with CFR-PEEK2 between November 2016 and April 2018. Follow-up was performed after a minimum of 24 months, evaluating the functional degree of movement functional scores, including the Subjective Shoulder Value (SSV) as well as an age- and sex-adapted Constant-Murley score (CMS). The 2-year results were compared to the results of a matched pair group comprising patients that were treated with TAL-P during the same period.
Of the 35 patients included (mean age: 61.2 [18-78] years), 30 (86%) patients completed the 24-month follow-up in the CFR-PEEK2-group. After 24 months, the mean CMS was 89.9 points (pt) (44.5-100 pt) and the mean SSV was 86.7% (35-100%). Compared to the matched-pair TAL-P cohort, the 24-month follow-up showed similar results (CMS: 88.6 pt. (40.5-100 pt.) [p = 0.9]; SSV: 76% (30-100%) [p = 0.05]). However, significantly better degrees of forward flexion and internal rotation as well as a better range of motion in abduction was recorded in patients treated with CFR-PEEK2 plates than TAL-P.
At the 24-month follow-up, patients who received treatment with CFR-PEEK2 compared to those that received TAL-P showed enhanced range of motion whilst having similar clinical scores.
本研究旨在分析和比较 CFR-PEEK2 与传统钛板接骨术（TAL-P）治疗患者 24 个月的活动范围结果。我们假设在 2 年随访中，CFR-PEEK2 组的临床结果相似，但活动范围更好。
本回顾性研究分析了 2016 年 11 月至 2018 年 4 月期间接受 CFR-PEEK2 治疗的所有 PHF 患者的前瞻性收集数据。在至少 24 个月后进行随访，评估运动功能评分的功能运动程度，包括主观肩部值（SSV）以及年龄和性别适应的恒定 - 默里评分（CMS）。将 2 年的结果与同期接受 TAL-P 治疗的配对患者组的结果进行比较。
在纳入的 35 例患者中（平均年龄：61.2 [18-78] 岁），CFR-PEEK2 组有 30 例（86%）患者完成了 24 个月的随访。24 个月后，平均 CMS 为 89.9 分（44.5-100 分），平均 SSV 为 86.7%（35-100%）。与配对 TAL-P 队列相比，24 个月的随访结果相似（CMS：88.6 分（40.5-100 分）[p=0.9]；SSV：76%（30-100%）[p=0.05]）。然而，接受 CFR-PEEK2 板治疗的患者的前屈和内旋角度明显更好，外展活动范围也更好。
在 24 个月的随访中，与接受 TAL-P 治疗的患者相比，接受 CFR-PEEK2 治疗的患者的活动范围更大，而临床评分相似。
