目的通过前瞻性研究探讨微创内固定系统(LISS)治疗老年骨质疏松性股骨远端骨折的疗效。方法采用LISS微创治疗18例老年骨质疏松性股骨远端骨折,对膝关节功能及并发症等资料进行分析。结果本组随访15～36个月,骨折均获愈合,无切口感染及再骨折等并发症。膝关节功能按Merchant评分:优12例,良4例,可2例,优良率88.89%。结论熟知LISS的生物力学原则及技术要点、恢复股骨内侧皮质支持、积极抗骨质疏松是提高骨质疏松性股骨远端骨折固定稳定性的重要因素,有助于减少术后并发症并获得良好的膝关节功能。
Objective To investigate the efficacy of minimally invasive internal fixation system (LISS) in the treatment of distal osteoporotic distal femoral fractures by prospective study. Methods LISS minimally invasive treatment of 18 cases of osteoporotic distal femoral fractures, knee function and complications were analyzed. Results The follow-up of 15 to 36 months in this group, the fractures were healed, no incision infection and complications such as fracture. Merchant score according to Merchant score: excellent in 12 cases, good in 4 cases, fair in 2 cases, good rate of 88.89%. Conclusions Well-known principles and technical points of LISS biomechanics, restoration of medial femoral cortex and active anti-osteoporosis are important factors to improve the stability of osteoporosis distal femoral fractures, which will help to reduce postoperative complications and obtain good Knee function.
