About this trial
Thirty-seven patients diagnosed with femoral fracture to be treated with a compatible plate will be enrolled for this multicenter prospective interventional study. The Fracture Monitor T1 will be attached to the locking plate during osteosynthesis. Prior to discharge, it will be connected to an app installed either on the patients' smartphone or on the smartphone provided by the sponsor. The device will continuously collect and process data, which can automatically be downloaded via Bluetooth through the smartphone app and transferred in encrypted form to a dedicated cloud server. The smartphones will be equipped with a basic app version with rudimentary user interface that has no data visualization function. During the rehabilitation phase, data collected by the device will not be accessible to the surgeon nor the patient to ensure that no therapeutic decision will be made based on the acquired data. Every patient is treated as per standard of care.
The primary objective of the study is to collect safety information of the Fracture Monitor T1. The secondary objectives are to collect information on device performance, device handling, and usability.
All adverse events (AEs) and serious AEs (SAEs) will be recorded during the study. These will be reviewed and evaluated for their potential relationship to the device.
All patients will be followed up for 6 months after the surgery according to the local standard of care. Given that the removal of the Fracture Monitor T1 may occur beyond 6 months, a safety follow-up will take place at the time point when the Fracture Monitor T1 is removed as per the instructions for use if it has not been removed within the 6 months.
The results will be compiled into a clinical evaluation report to be submitted as part of the technical documentation for the conformity assessment procedure.

Trial outcomes
Primary outcomes
Incidence of ADEs
To evaluate the safety, (ie the incidence of adverse device effects (ADEs), of the investigational device Fracture Monitor T1 in femoral fracture patients)
Secondary outcomes
Clinical performance: Relationship - implant load/bone healing
Relationship between relative implant load and bone healing status
Clinical performance: Relationship - implant load/weight bearing
Relationship between relative implant load and prescribed weight bearing
Clinical performance: Relationship - implant load/Function Index for Trauma(FIX-IT)
Relationship between relative implant load and Function Index for Trauma (FIX-IT) score FIX-IT: max 12 points - 0 worse/12 best
Clinical performance: Relationship - implant load/Patient reported outcomes
Relationship between relative implant load and Patient reported outcomes: pain, EuroQol 5- dimension (EQ-5D) EQ-5D health states can be summarised using a 5-digit code or represented by a single summary number (index value) which reflects how good or bad a health state is according to the preferences of the general population of a country/region.
