“…As the aging population continues to rise, there has been a concomitant increase in the number of elderly patients with wrist fractures. 14 – 16 This is particularly relevant to middle-aged and elderly women because of the negative impact that the menopause and oestrogen loss has on their bone health; and along with age-related declines in physical function and their ability to deal with emergencies, they are at a high risk of wrist fractures. 13 , 17 – 19 In addition, wrist fractures are also common in young and middle-aged people as a result of injuries caused by their daily exercise and work.…”

Objective To assess the biomechanical properties that influence wrist fracture, so as to provide the theoretical basis for simulation experiments to aid the optimal design of wrist protectors. Methods Six cadaveric wrists were included as experimental specimens. Wrist specimens wearing wrist protectors formed the experimental group and unprotected wrist specimens formed the control group. The wrist specimens were axially loaded under physiological loads and the stress magnitude and distribution of the experimental and control groups were obtained. A three-dimensional wrist finite element model of a healthy volunteer was developed to verify the rationality and effectiveness of the cadaveric wrist models. Results Under normal physiological loads, the stress on the radioulnar palmar unit was high and manifested in the form of pressure, while the stress on the radioulnar dorsal unit was lower and manifested in the form of tension. The stresses on the radial distal palmar, ulnar distal palmar, radial distal dorsal, ulnar distal dorsal, radial proximal palmar and ulnar proximal palmar units in the experimental group were less than those in the control group. Conclusion Under physiological loads, wearing a wrist protector can reduce the stress on the radioulnar distal palmar, radioulnar proximal palmar and radioulnar distal dorsal units, while having no obvious effect on the radioulnar proximal dorsal units.

“…As the aging process of the population continues to evolve, the increase in the proportion of elderly people has led to a surge in patients with wrist fractures to a certain extent [15][16][17]. Especially in middle-aged and elderly women due to menopause and estrogen loss, physical function and the ability to deal with emergencies has inevitably declined, which results in a high incidence of wrist fractures [13,[18][19][20].…”

Objective To evaluate the biomechanical analysis and effect of the wrist protector and provide a theoretical basis for wrist fractures and the optimal design of wrist protectors. Methods 6 cadaveric wrist models were axially loaded 600 N stress, and the stress magnitude and distribution of the experimental group (wearing wrist protectors) and control group were obtained. Furthermore, a three-dimensional finite element analysis was conducted to verify the scientificity and effectiveness of the models. Results The stresses on the radial distal palmar, ulnar distal palmar, radial distal dorsal, ulnar distal dorsal, radial proximal palmar and ulnar proximal palmar units in the experimental group were lower than those in the control group (P < 0.05). However, the stresses on the radial proximal dorsal and ulnar proximal dorsal units were higher than those in the control group (P>0.05). Conclusion The stress on the radioulnar palmar unit was high, while the radioulnar dorsal unit one was relatively low. Within the range of physiological loads, wearing wrist protectors can significantly reduce the stress on the radioulnar distal palmar, radioulnar proximal palmar and radioulnar distal dorsal units.

Objectives This study combined mechanical experiments and finite element analysis (FEA), and verified each other, to assess the biomechanical analysis and effect of wrist fracture, providing theoretical basis for the simulation experiments of wrist fracture and optimal design of wrist protector. Methods and Materials Six cadaveric wrists were included to create experimental specimens. After grouping, the wrist models were axially loaded under physiological load of 600 N, the stress magnitude and distribution of experimental group and control group were obtained. Moreover, a three-dimensional (3D) wrist finite element model (FEM) of a healthy volunteer was developed to verify the rationality and effectiveness of wrist models. Results Within the range of physiological load, the stress of radioulnar palmar unit was high and in shape of pressure, while the stress of radioulnar dorsal unit was relatively lower and in shape of tension. The stresses of radial distal palmar, ulnar distal palmar, radial distal dorsal, ulnar distal dorsal, radial proximal palmar and ulnar proximal palmar units in experimental group were less than those in control group. However, the stresses of radial proximal dorsal and ulnar proximal dorsal units were higher than those in control group. Conclusions Under physiological load, wearing wrist protector can apparently reduce the stress on radioulnar distal palmar, radioulnar proximal palmar and radioulnar distal dorsal units, while has no obvious effect on radioulnar proximal dorsal units. During the process of designing and improving the wrist protector, it is reasonable to place the stress center on radioulnar distal palmar and dorsal units.
