How We Define Patient-Specific Weight-Bearing Protocol

Reusable biofeedback Smart Crutch Tips attach in seconds to any standard crutches in place of regular rubber tips, connect via Bluetooth to a mobile app, and automatically monitor weight-bearing, alerting the patient with sound, lights, and voice guidance whenever they move outside the prescribed range. When walking on crutches, there is a moment during which the healthy leg is completely lifted off the ground, and the entire load is distributed between the crutches and the injured leg. We can determine how much load is placed on the injured limb by subtracting the amount of weight on the crutches from the patient’s body weight. For example, if a patient’s weight is 200 lb and during a step he transferred 140 lb to crutches, then 60 lb of pressure was exerted on the injured limb. | ComeBack Mobility helps surgeons prescribe the optimal weight-bearing load after lower limb fractures based on biomechanical analysis. As is well known, in most cases, the optimal interfragmentary movement in the fracture zone is approximately 1 mm. Therefore, the patient should load the leg with a weight that leads to this movement while ensuring that the internal or external fixation can withstand it.
