There are concerns regarding nail/medullary canal mismatch and initial stability after cephalomedullary nailing in unstable pertrochanteric fractures. This study aimed to investigate the effect of an additional anteroposterior blocking screw on fixation stability in unstable pertrochanteric fracture models with a nail/medullary canal mismatch after short cephalomedullary nail (CMN) fixation.

附加前后路阻断螺钉对不稳定转子周围骨折头髓钉钉/髓管失配的影响:有限元分析。

在不稳定的转子周围骨折中,头髓钉后的钉/髓管不匹配和初始稳定性存在问题。本研究旨在探讨在短头髓钉 (CMN) 固定后,在钉/髓管不匹配的不稳定转子前骨折模型中,额外的前后阻滞螺钉对固定稳定性的影响。
