Objective: To summarize the research progress of medial buttress plate assisted fixation for femoral neck fractures in young adults.
Methods: The literature about buttress plate assisted fixation for femoral neck fractures in young adults was widely reviewed and analyzed. The design principle, background, biomechanical characteristics, and clinical results of buttress plate were summarized.
Results: Medial buttress plate assisted fixation is the latest treatment of femoral neck fractures in young adults, which can convert the shear force at the fracture sides into compression force and promote fracture healing. Medial buttress plate can improve the biomechanical stability of femoral neck fractures and reduce the maximum stress of fixation implants. In clinical, the medial buttress plate can maintain fracture reduction, reduce the incidences of nonunion and surgical failure, and improve hip joint function.
Conclusion: Medial buttress plate assisted fixation can achieve good effectiveness for femoral neck fractures in young adults. However, due to the preliminary application, its indications, fixation implants, and long-term effectiveness need to be further studied and improved.
目的: 总结内侧支撑钢板辅助固定治疗青壮年股骨颈骨折的研究进展。.
方法: 广泛查阅近年国内外有关支撑钢板及其用于青壮年股骨颈骨折治疗的文献，从支撑钢板的设计原理、应用背景、生物力学特征以及临床疗效等方面进行总结归纳。.
结果: 内侧支撑钢板辅助滑动加压固定是青壮年股骨颈骨折的最新治疗手段，可以将骨折端的剪切力转换为挤压力，促进骨折愈合。内侧支撑钢板可以提高股骨颈骨折的生物力学稳定性，降低固定材料的最大应力。临床应用显示内侧支撑钢板可以维持股骨颈骨折复位，降低骨折不愈合和手术失败率，改善术后关节功能。.
结论: 内侧支撑钢板辅助固定治疗青壮年股骨颈骨折可获得较好疗效，但临床应用时间较短，在手术指征、固定材料、长期疗效等方面有待进一步研究。.
