Orthopaedic surgeons commonly prescribe weight-bearing parameters for their patients for a variety of reasons. Weight-bearing may be limited in order to control the healing environment, but advancing a patient's weight-bearing status is preferably done as quickly as possible to maximize functional recovery. However, it is entirely unclear to what extent these prescriptions are followed in practice. The purpose of this scoping review is to identify and compare non-invasive devices used for the measurement of weight-bearing following lower extremity fractures.
Database searches of MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) were completed to identify relevant studies. Titles were screened for relevance, and abstracts were screened against the eligibility criteria. We identified studies that investigated the use of external force, pedal pressure, or activity monitoring devices used in adults after lower extremity fractures and excluded studies involving compartment pressure measurement.
Sixty-two studies met the inclusion criteria. About 39% of studies used an insole-type device, which could be worn in a shoe or integrated into a removable boot. Other device types included step count or activity monitors (52%), force plates (18%), pressure film (2%) and external pedobarography systems (27%).
We found that different monitors offered varying types of measurements and are suitable for a variety of applications. Therefore, selecting the ideal device depends on the metric of interest. Further high-quality prospective studies utilizing device monitoring are needed to validate the theory that early weight-bearing is beneficial and safe for patients with lower extremity fractures.
出于多种原因，骨科医生通常会为患者规定负重参数。为了控制愈合环境，负重可能会受到限制，但最好尽快提高患者的负重状态，以最大限度地促进功能恢复。然而，在实际操作中这些规定的遵循程度尚不清楚。本综述的目的是识别和比较用于测量下肢骨折后负重情况的非侵入性设备。
完成了对MEDLINE、EMBASE和Cochrane对照试验中央注册库（CENTRAL）的数据库检索，以识别相关研究。对标题进行相关性筛选，并根据纳入标准对摘要进行筛选。我们纳入了研究下肢骨折后成人使用的外力、踏板压力或活动监测设备的研究，并排除了涉及骨筋膜室压力测量的研究。
62项研究符合纳入标准。约39%的研究使用鞋垫式设备，这种设备可以穿在鞋子里或集成到可拆卸的靴子中。其他设备类型包括步数计数器或活动监测器（52%）、测力板（18%）、压力膜（2%）和外部足底压力测量系统（27%）。
我们发现不同的监测器提供不同类型的测量，适用于各种应用。因此，选择理想的设备取决于感兴趣的指标。需要进一步开展利用设备监测的高质量前瞻性研究，以验证早期负重对下肢骨折患者有益且安全这一理论。
