OBJECTIVE: The aim of this study was to analyze walking ability of patients following VFFF operation and to determine if there are long term walking disabilities.
UNASSIGNED: The retrospective cohort study involved healthy controls and patients who had undergone VFFF between 2012 and 2019 at the oral and maxillo-facial department of the University Hospital in Lausanne, Switzerland. Patients with cardiovascular, pulmonary, neuromuscular or musculoskeletal pathologies that could impair walking were excluded from the study.
UNASSIGNED: Primary predictor is the reconstruction status, VFFF versus healthy patients (controls).
METHODS: Main outcomes were gait parameters. Objective evaluation of walking abilities was assessed using the Gait Up system (Gait Up SA, EPFL Innov\'Park-C, Lausanne, Switzerland), which are wearable motion sensors that provides 3D analytics of the gait.
UNASSIGNED: Covariates implied patient characteristics such as age, sex, time after surgery and subjective evaluation of the gait obtained with two orthopedic validated questionnaires.
RESULTS: This study implied 10 healthy controls and 11 patients who had undergone VFFF. Results showed statistically significant differences in the speed [m/s] (1.3 vs 1.1 for a P value of .001), the stride length [m] (1.4 vs 1.2 for a P value of 0.003), the flat foot phase [%] (55.0 vs 63.3 for a P value of .006) and the pushing phase [%] (34.1 vs 25.1 for a P value of .008).
CONCLUSIONS: Reconstruction using vascularized autograft in maxillofacial surgery is substantial and well described. Our attention focusing on donor site morbidity has demonstrated subjective and objective long-term alterations. These results will have to be confirmed with gait analysis in a prospective project including preoperative and postoperative analysis of the gait of the patient acting himself as his own control, with a larger scale of patients.
目的:本研究的目的是分析VFFF手术后患者的步行能力,并确定是否存在长期步行障碍。
■回顾性队列研究涉及2012年至2019年在洛桑大学医院口腔和颌面部部门接受VFFF的健康对照和患者,瑞士。心血管患者,肺,本研究排除了可能损害行走的神经肌肉或肌肉骨骼病变.
■主要预测因子是重建状态,VFFF与健康患者(对照)的比较。
方法:主要结果是步态参数。使用步态系统评估步行能力的客观评估(GaitUpSA,EPFLInnov\'Park-C,洛桑,瑞士),它们是可穿戴的运动传感器,提供步态的3D分析。
■协变量隐含的患者特征,如年龄,性别,手术后的时间和步态的主观评估通过两个骨科验证问卷获得。
结果:本研究包含10名健康对照者和11名接受VFFF的患者。结果显示速度[m/s]的统计学差异(P值为.001时,1.3vs1.1),步幅[m](P值为0.003时,为1.4vs1.2),平足阶段[%](P值为.006时55.0vs63.3)和推动阶段[%](P值为.008时34.1vs25.1)。
结论:在颌面外科中使用血管化自体移植进行重建是实质性的,并且有很好的描述。我们对供体部位发病率的关注已经证明了主观和客观的长期变化。这些结果必须通过前瞻性项目中的步态分析来确认,包括术前和术后对患者作为自己控制的步态进行分析,患者规模较大。
