The aim of the present study is to evaluate the use of the Less Invasive Stabilization System (LISS) plate for distal femoral fractures, examining variables such as type of fracture and length of plate. A retrospective study of 30 patients with a distal femoral fracture, treated with a distal femur LISS plate (Synthes) was performed. Average age was 71 years old (20-101). According to the AO classification, 16 fractures were type A, 5 type B, and 9 type C. The consolidation index and clinical outcomes measured with Knee Society Score (KSS) questionnaire were evaluated. Fracture consolidation took an average time of 16 weeks (14-20). Mean KSS was 77,3 (50-97) at the 2-year follow-up visit, observing better outcomes on type C fractures (84,25). According to the KSS score, only two cases were described with bad functional outcomes (6%). Distal femur fractures treated with the LISS plate achieved 94% of good and acceptable outcomes. Unlike the previously published, the best results were obtained with AO type C fractures, probably associated to the lower age (mean 53 years old) and better functional recovery capacity of this group.
本研究的目的是评估微创稳定系统（LISS）钢板在股骨远端骨折中的应用，研究骨折类型和钢板长度等变量。对30例采用股骨远端LISS钢板（辛迪思）治疗的股骨远端骨折患者进行了回顾性研究。平均年龄为71岁（20 - 101岁）。根据AO分类，16例骨折为A型，5例为B型，9例为C型。评估了采用膝关节协会评分（KSS）问卷测量的骨痂形成指数和临床结果。骨折愈合平均用时16周（14 - 20周）。在2年随访时，平均KSS为77.3（50 - 97），C型骨折的结果更好（84.25）。根据KSS评分，只有2例功能结果较差（6%）。采用LISS钢板治疗的股骨远端骨折获得了94%的良好和可接受结果。与之前发表的研究不同之处在于, AO C型骨折取得了最佳结果，这可能与该组患者年龄较小（平均53岁）以及功能恢复能力较好有关。
