Whether a comminuted pelvic fracture will cause paralysis depends on the situation. First, if a pelvic fracture is comminuted but does not cause nerve damage, paralysis does not occur. This is because at this time the pelvic fracture is only a fracture and does not cause damage to the surrounding organs. Second, it may cause damage to the peripheral nerves, such as the sciatic nerve or the femoral nerve, and paralysis of the lower limbs may occur, but in general, unless the fracture is very severe and causes nerve damage, most of them will not occur. Third, a comminuted fracture of the pelvis, if it is causing damage to the pelvic organs can appear as damage to the rectum, bladder damage, ureter and even some other injuries. Fourthly, if the pelvic fracture is infected, or even further aggravated, or even soft tissue loss, it can also cause nerve damage and lower limb paralysis.
