背景:对碳/PEEK板和指甲的兴趣一直在增加。接近骨骼的弹性模量,高承载能力和透射线性使CFR/PEEK材料成为潜在的突破。在文学中,CFR/PEEK钢板治疗肱骨近端有丰富的资料,桡骨远端和腓骨远端骨折。在受骨转移影响的患者中,经过12个月的随访,CFR/PEEK指甲被证明是有效和安全的。对CFR/PEEK指甲在受其他病理影响的患者中的表现知之甚少。
目的:该研究的目的是评估CFR/PEEK指甲治疗各种病理状况的安全性和有效性。还研究了这种指甲的任何射线透过性都可能导致对骨痂或疾病部位的更客观的评估。
方法:在研究组中,包括20例接受CFR/PEEK钉植入的患者(22个骨段)(8个肱骨,一个胫骨,九个股骨和四个膝关节固定术)。他们受到病理性骨折的影响,在四种情况下,他们需要膝关节固定术。考虑到指甲失败和骨痂或疾病进展(RUSH评分),对它们进行了回顾性评估。平均随访时间为11个月(min6.8-max20.3)。在对照组中,包括在同一机构接受相同病理的钛钉治疗的患者。考虑到来自两个机构的两名专家外科医生的RUSH评分,对两组进行了类间相关系数(ICC)分析,以评估射线可透性是否可以更客观地评估疾病或骨痂部位。
结果:在CFR/PEEK组中,RUSH评分之间的ICC平均值为0.882(IC95%:0.702-0.953),而钛组为0.778(IC95%:0.41-0.91)。观察者的评估显示,钛钉的遮挡明显高于CFR/PEEK钉。两组均未报告骨连接失败。
结论:我们的结果证实了CFR/PEEK指甲在中短期内的安全性。与具有较高ICC的钛组相比,这些材料的射线可透性使我们的观察者对骨痂形成或疾病进展进行了更客观的评估。
方法:III病例对照治疗研究。
BACKGROUND: Interest around carbon/PEEK plates and nails has been raising. The elastic modulus close to the bone, the high load-carrying capacity and radiolucency make CFR/PEEK materials a potential breakthrough. In the literature, there are abundant data about CFR/PEEK plates in the treatment of proximal humerus, distal radius and distal fibula fractures. In patients affected by bone metastasis, CFR/PEEK nails were proved effective and safe with 12 months of follow-up. Very little is known about performances of CFR/PEEK nails in patients affected by other pathologies.
OBJECTIVE: The aim of the study was to evaluate safety and efficacy of CFR/PEEK nails in the treatment of various pathological conditions. It was also investigated whatever radiolucency of this nails could lead to a more objective evaluation of bone callus or disease site.
METHODS: In the study group were included 20 patients (22 bone segments) who underwent CFR/PEEK nail implantation (eight humerus, one tibia, nine femur and four knee arthrodesis). They were affected by pathological fractures, and in four cases, they required an arthrodesis of the knee. They were retrospectively evaluated considering nail failures and bone callus or disease progression (RUSH scores). Mean follow-up time was 11 months (min 6.8-max 20.3). In the control group were included patients treated with titanium nails in the same institution for the same pathologies. An interclass correlation coefficient (ICC) analysis was performed in both groups considering RUSH scores by two expert surgeon from two institution to assess whether radiolucency could lead to a more objective evaluation of disease or bone callus site.
RESULTS: The ICC of mean values between RUSH scores was 0.882 (IC 95%: 0.702-0.953) in the CFR/PEEK group, while it was 0.778 (IC 95%: 0.41-0.91) in the titanium group. Observers\' evaluation showed a significantly higher obscuration by titanium nails than by CFR/PEEK nails. No osteosynthesis failures were reported in both groups.
CONCLUSIONS: Our results confirm the safety of CFR/PEEK nails in the short-medium term. The radiolucency of these materials led our observers to perform more objective evaluations of bone callus formation or disease progression compared to the titanium group given the higher ICC.
