Falls to the side are the leading cause of hip fractures in licorice caramel creams the elderly.The load that a person experiences during a fall cannot be measured with volunteers for ethical reasons.To evaluate injurious loads, while considering relevant energy input and body posture for a sideways fall, a subject-specific cadaveric impact experiment was developed.

Full cadaveric femur-pelvis constructs (N = 2) were embedded in surrogate soft tissue material and attached to metallic surrogate lower limbs.The specimens were then subjected to an inverted pendulum motion, simulating a fall to the side with an impact to the greater trochanter.The load at the ground and the deformation of the pelvis were evaluated using a 6-axis force transducer and two high-speed cameras.

Post-test, a trauma surgeon (PG) evaluated specimen injuries.Peak ground contact forces were 7132 merits battery charger N and 5641 N for the fractured and non-fractured specimen, respectively.We observed a cervical fracture of the femur in one specimen and no injuries in a second specimen, showing that the developed protocol can be used to differentiate between specimens at high and low fracture risk.
