Segond fracture may be identified when an anterior cruciate ligament (ACL) tear is diagnosed, and it has historically been considered a sign of significant knee trauma indicating intra-articular injury. There are few studies on the correlation between a Segond fracture and meniscus injury. The purpose of this study was to evaluate the relationship between a Segond fracture and meniscus injury in patients with ACL tears.
A retrospective review of all patients undergoing acute ACL reconstruction (less than 1 month from the time of injury) between 2013 and 2020 was performed. The absence or presence of a Segond fracture was confirmed using preoperative radiographs. Demographic data (age, sex and body mass index), injury variables (time from injury and mechanism of injury) and arthroscopic features (meniscal or chondral injury) were analysed to investigate the relationship between a Segond fracture and meniscus injury.
A total of 427 patients were included in the study. The incidence of Segond fractures was 12.4%. Among the patients with a Segond fracture, 15 patients were injured playing soccer (28.3%), 11 patients were injured playing basketball (20.8%), eight patients sustained the injury during racquet sports (15.1%), five patients (9.4%) were injured during less popular sports (such as skiing, ice-skating and boxing), and 14 patients (26.4%) were injured by contact mode of injury. A Segond fracture was a significant risk factor for lateral meniscus tears in patients with ACL tears (adjusted odds ratio, 1.938; 95% confidence interval, 1.078-3.481; P = 0.027).
The incidence of Segond fractures in patients with acute ACL tears was higher than that reported in previous studies. A Segond fracture could increase the risk of a lateral meniscus tear in patients with an ACL tear.
当诊断出前交叉韧带 (ACL) 撕裂时，可能会发现 Segond 骨折，并且它一直被认为是膝关节创伤的标志，表明关节内损伤。关于 Segond 骨折与半月板损伤之间的相关性研究甚少。本研究旨在评估 ACL 撕裂患者中 Segond 骨折与半月板损伤之间的关系。
对 2013 年至 2020 年间所有接受急性 ACL 重建（受伤后 1 个月内）的患者进行回顾性研究。使用术前 X 线片确认是否存在 Segond 骨折。分析人口统计学数据（年龄、性别和体重指数）、损伤变量（受伤时间和受伤机制）和关节镜特征（半月板或软骨损伤），以研究 Segond 骨折与半月板损伤之间的关系。
共有 427 例患者纳入本研究。Segond 骨折的发生率为 12.4%。在存在 Segond 骨折的患者中，15 例患者因踢足球（28.3%）受伤，11 例患者因打篮球（20.8%）受伤，8 例患者因球拍运动（15.1%）受伤，5 例患者（9.4%）因不太流行的运动（如滑雪、滑冰和拳击）受伤，14 例患者（26.4%）因接触伤模式受伤。Segond 骨折是 ACL 撕裂患者发生外侧半月板撕裂的显著危险因素（调整优势比，1.938；95%置信区间，1.078-3.481；P=0.027）。
急性 ACL 撕裂患者中 Segond 骨折的发生率高于既往研究报道。Segond 骨折可增加 ACL 撕裂患者发生外侧半月板撕裂的风险。
