目的

探讨通过深度学习模型测量股骨转子间骨折髓内钉固定术后参数与人工测量的差异。

方法

回顾性纳入2024年1月至12月首都医科大学附属北京积水潭医院创伤骨科收治的符合入选标准的行单侧髓内钉固定的股骨转子间骨折患者150例,其中接受防旋股骨近端髓内钉(PFNA)、Gamma型髓内钉及InterTan型髓内钉固定者各50例。男81例,女69例,年龄(64.1±17.3)岁;左侧79例,右侧71例。分别使用深度学习模型和人工方法测量股骨转子间骨折髓内钉固定术后颈干角、尖顶距(TAD)、股骨内侧皮质支撑情况,并进行比较。采用Bland-Altman方法评估2种测量方法的一致性。

结果

TAD在全部病例及各亚组中,深度学习模型与人工方法测量差异均无统计学意义(P>0.05),总体平均偏移为(-0.21±5.29) mm,Bland-Altman分析显示一致性良好。股骨内侧皮质支撑情况测量总体Kappa值为0.716,其中PFNA组一致性最佳(Kappa=0.803),Gamma型髓内钉组与InterTan型髓内钉组依次为0.675和0.651。深度学习模型测量总体颈干角较人工方法偏高,尤其在InterTan型髓内钉组差异有统计学意义(P<0.001),而在PFNA组与Gamma型髓内钉组差异无统计学意义(P>0.05)。

结论

深度学习模型在TAD、股骨内侧支撑情况以及PFNA型和Gamma型髓内钉固定术后颈干角测量方面与人工方法具有较好的一致性,但InterTan型髓内钉固定术后颈干角测量存在系统性偏倚,提示该模型仍需针对复杂双螺钉构型进一步优化。

Objective

To investigate the differences between a deep learning model and manual measurement in assessing postoperative parameters of intertrochanteric femoral fractures after intramedullary nail fixation.

Methods

A retrospective study was conducted, including 150 patients with intertrochanteric femoral fractures who met the inclusion criteria and underwent unilateral intramedullary nail fixation at the Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital, Capital Medical University, from January to December 2024. Among them, 50 patients each in the proximal femoral nail antirotation (PFNA), Gamma-type intramedullary nail, and InterTan intramedullary nails groups. There were 81 males and 69 females, aged (64.1±17.3) years; 79 cases were on the left side and 71 on the right. The deep learning model and manual method were used to measure the postoperative neck-shaft angle, tip-apex distance (TAD), and medial femoral cortex support, and the results were compared. Bland-Altman analysis was used to evaluate the agreement between the two measurement methods.

Results

For TAD, there was no statistically significant difference between the deep learning model and manual measurement in all cases and each subgroup (P>0.05). The overall mean difference was (-0.21±5.29) mm, and Bland-Altman analysis showed good agreement. The overall Kappa value for the measurement of medial femoral cortical support was 0.716, with the best agreement in the PFNA group (Kappa=0.803), followed by the Gamma-type intramedullary nail group and InterTan intramedullary nail group (0.675 and 0.651, respectively). The overall neck-shaft angle measured by the deep learning model was higher than that measured by the manual method, especially in the InterTan intramedullary nail group, where the difference was statistically significant (P<0.001), while no statistically significant difference was found in the PFNA group or the Gamma-type intramedullary nail group (P>0.05).

Conclusion

The deep learning model showed good agreement with the manual method in measuring TAD and medial femoral cortical support, as well as postoperative neck-shaft angle in the PFNA and Gamma-type intramedullary nail fixation. However, there was a systematic bias in the measurement of postoperative neck-shaft angle in the InterTan intramedullary nail fixation, suggesting that the model still needs further optimization for complex dual-screw configurations.
