Fracture healing is usually monitored by clinical impressions and radiographs. Objective and easy methods for assessing fracture healing without radiation would be beneficial. The aim of this study was to analyse whether weight and plantar pressure while standing can be used to monitor healing of tibial or malleolar fractures and whether these parameters can discriminate between patients with and without union. Thirteen patients were longitudinally assessed during each postoperative clinical visit, of whom two developed a nonunion. Eleven matched healthy controls were assessed once. Additionally, five patients already experiencing nonunion were assessed once at the time of their nonunion diagnosis. All participants performed a standing task for ten seconds with pressure-sensing insoles. Greatest improvements were detected throughout the first three months in patients with union. However, six months after surgery, more than half of the parameters were still significantly different from those of the controls. The weight and pressure distributions did not differ between patients with or without union six months after surgery. A standing task can be used to monitor improvements in weight and pressure distribution throughout the healing process of tibial or malleolar fractures, but lacks potential to discriminate between patients with or without fracture union.
骨折愈合通常通过临床印象和 X 光片来监测。如果有一种无需辐射即可客观、简便地评估骨折愈合的方法将是有益的。本研究的目的是分析在不接受辐射的情况下，站立时的体重和足底压力能否用于监测胫骨或踝部骨折的愈合情况，以及这些参数能否区分有和无愈合的患者。13 名患者在每次术后临床就诊时进行了纵向评估，其中 2 名患者发生了骨不连。11 名匹配的健康对照者仅进行了一次评估。此外，在诊断为骨不连时，对 5 名已经发生骨不连的患者进行了一次评估。所有参与者均使用压力感应鞋垫进行了十秒的站立任务。在有愈合的患者中，整个前三个月都检测到了最大的改善。然而，术后 6 个月，超过一半的参数仍与对照组有显著差异。术后 6 个月，有和无骨不连的患者的体重和压力分布没有差异。站立任务可用于监测胫骨或踝部骨折愈合过程中体重和压力分布的改善，但缺乏区分有和无骨折愈合患者的潜力。
