When the degree of fracture is light and the displacement is not obvious, the clinical manifestations include localized pain in the left hip joint and limitation of activities. If the degree of injury is more serious, accompanied by hip dislocation, or even urethra injury, the clinical manifestations, in addition to the above pain and activity limitation, there are also deformities of the left lower limb caused by the corresponding dislocation (e.g., left lower limb shortening deformity due to centric dislocation), and even the fracture damage to the urethra, the patient has difficulty in urination or blood in the urine, etc. If the patient is suspected of having an acetabular fracture, the clinical manifestations will be different. If a patient is suspected of having an acetabular fracture, it is important to monitor the patient’s vital signs and exclude the possibility of pelvic hemorrhage to avoid life-threatening injuries due to missed diagnosis.
