摘要:

目的 探究 3D 打印(3DP)定制钢板联合股骨近端防旋髓内钉(PFNA)在外侧壁粉碎的股骨 转子间骨折(IFF)中的应用价值。方法 选择 2018 10 月至 2021 3 月我院收治的 108 例外侧壁粉碎的 IFF 患者为研究对象。根据不同治疗方案分为两组,PFNA 组(n = 52)使用 PFNA,Unite 组(n = 56)为在 PF⁃ NA 组基础上联合 3DP 定制钢板治疗。对比分析两组患者的一般资料、手术指标、Harris 评分、炎症因子、 术后并发症及满意度。采用随机行走模型评价两组患者手术指标、术后髋关节功能及炎症因子改善情 况。结果 PFNA 组相比,Unite 组骨折愈合时间更短及下床活动时间更短(P < 0.05)。与 PFNA 组相 比,Unite 组术后 12 个月疼痛、功能、畸形、关节活动度及 Harris 总分均更高(P < 0.05),术后 1 个月肿瘤坏 死因子⁃α(TNF⁃α)、白细胞介素⁃6(IL⁃6)及白细胞介素⁃1(IL⁃1)水平均更低(P < 0.05)。随机行走模型评价 结果显示,Unite 组手术指标、术后髋关节功能及炎症因子的改善情况显著优于 PFNA 组。与 PFNA 组相 比,Unite 组术后 12 个月并发症发生率更低(P < 0.05),满意度更高(P < 0.05)。结论 对于治疗外侧壁粉碎的 IFF 患者,3DP 定制钢板联合 PFNA 治疗,手术指标、术后髋关节功能及炎症因子的改善情况显著优于 单用PFNA,且术后12个月并发症发生率更低、满意度更高。

Abstract:

Objective To explore the application value of 3D ⁃ printing(3DP)customized steel plate combined with proximal femoral nail antirotation(PFNA)for intertrochanteric fracture of femur(IFF)with commi⁃ nuted lateral wall. Methods A total of 108 patients with IFF with comminuted lateral wall who had been treated in our hospital from October 2018 to March 2021 were selected as research subjects. According to different treatment plans,they were divided into PFNA group(n = 52)and Unite group(n = 56). The general data,surgical indica⁃ tors,Harris score,inflammatory factors,postoperative complications,and degree of satisfaction were compared and analyzed between the two groups. The random walk model was used to evaluate the improvement in surgical indicators,postoperative hip function and inflammatory factors in both groups. Results As compared with PFNA group,Unite group had shorter fracture healing and ambulation time(P < 0.05). As compared with PFNA group unite group had higher scores on pain,function,deformity,and joint range of motion and greater Harris total score 12 months after surgery(P < 0.05),and lower levels of tumor necrosis factor⁃α(TNF⁃α),interleukin⁃6(IL⁃6 and interleukin⁃1(IL⁃1)one month after surgery(P < 0.05). The evaluation results of random walk model showed that the improvement in surgical indexes,postoperative hip function and inflammatory factors was significantly better in Unite group than in PFNA group. As compared with PFNA group,Unite group had a lower incidence of 12⁃month postoperative complications(P < 0.05)and higher degree of satisfaction(P < 0.05). Conclusions For IFF patients with comminuted lateral wall,the improvement in surgical indicators,postoperative hip function and inflammatory factors was significantly better in Unite group than in PFNA group,and the incidence of 12⁃month postoperative complications was lower and the degree of satisfaction was higher.
