Lower extremity weight-bearing disorder
Introduction
Introduction Lower limb weight-bearing disorder is one of the clinical symptoms of talus fracture and dislocation diagnosis. The talus is divided into the head, the neck and the body; the head and the scaphoid form the scapular joint, and the rear is the narrow talus neck; the talus is located at the rear not only the largest volume, but the upper part of the talus and the lower end of the tibia constitute the ankle joint. It is the most concentrated part of power transmission and often causes damage. Can be diagnosed according to the patient's history of trauma, clinical symptoms and X-ray film (positive, lateral and oblique).
Cause
Cause
Cause:
Often caused by compression and compression violence.
Pathogenesis:
Most of them are caused by compression when falling from a height, or by violent compression; especially when the back is stretched. At this time, the talus neck fracture was multiple, the second was the talus fracture. When the foot was in the middle position, it caused the talus fracture, while the talus fracture was more common. Similar violence can cause dislocation of the talus. Pay attention to the cause of rheumatism and the factors of external force.

Generally, there is no difficulty, and it can be diagnosed according to the patient's history of trauma, clinical symptoms and X-ray film (positive, lateral and oblique). The main clinical symptoms are swelling, pain and activity limitation of the ankle joint. The tender points are mostly confined to the underside of the ankle joint, and are consistent with the fracture line and the fracture line. In addition to the talus fractures, the weight-bearing function of the lower limbs is more difficult.
Diagnosis
Differential diagnosis
Talus necrosis, ischemic necrosis is more common. The talus is the only bone in the whole body that has no muscles to stop and attach. When the ankle joint is severely damaged, the blood supply to the talus is completely destroyed and ischemic necrosis occurs. Eventually, the talus body collapses and deforms, causing ankle joint osteoarthritis.
