In young people (age less than 55 years) after femoral head, femoral neck fracture, the preferred treatment should be surgical, with a reasonable screw or bioresorbable screw fixation, together with a sufficiently long weight-free protection period, a process that usually takes 4-6 months and most patients have a satisfactory outcome. The majority of patients are able to return to their previous jobs. However, there are some patients with unsatisfactory results, hip pain, difficulty walking, or even limping gait, just like the comedian said walking: one step of one meter seven; one step of one meter six. Among these signs and symptoms, the most important one, and the one that requires the most treatment, is the recurrent and gradually increasing hip pain. Sometimes the pain is so severe that the patient can hardly walk. This kind of pain generally has this pattern: at the beginning, it hurts when walking more, and it hurts when straining, and later it worsens, and it starts to hurt when changing from sitting to standing position, and it is difficult to walk with weight, and at the later stage, the hip joint also hurts at night, and it is difficult for the patient to sleep with “wooden chaos”. Why is this? The reasons for this pain are related to the fracture of the femoral head and neck, which are divided into the following three situations The first one is that the fracture end has healed smoothly, but the inevitable hip pain still appears, which is difficult to understand. This is because the traumatic violence at that time was so great that it caused the destruction of articular cartilage and damage to subchondral bone. Although the fracture heals, the cartilage is not effectively repaired, which then causes traumatic arthritis. The joint surface sclerosis is obvious and even forms a “marble slab” appearance in such patients. The subchondral bone also has cystic changes, which some doctors incorrectly diagnose as femoral head necrosis. In the second case, the fracture end failed to heal successfully, resulting in ischemic necrosis of the femoral head, causing joint pain, which is shown on the X-ray as a failure of the internal fixation and direct contact with the acetabulum. The bone of the femoral head is resorbed and osteoporotic, or has even disappeared. Or the internal fixation is still in the femoral head, but the fracture gap is large. In the third case, which occurs more specifically, this patient had a good and satisfactory result after surgery. So they went to the hospital to remove the internal fixation, but not long after the removal of the internal fixation, they found pain in the hip joint. The head of the femur was found to have collapsed in the radiographs taken at the hospital. There was a feeling of burning incense and causing a ghost. This was mainly because the joint surface was collapsed due to premature weight-bearing. It was a pity. Knowing the cause of the disease, the treatment also has a direction. In the first case, the patient should try to bear as little weight as possible and apply drugs to improve cartilage metabolism, which will help to relieve the symptoms. In the second and third cases, regardless of the age of the patient, surgery is needed to relieve the pain. The specific choice of that procedure is determined by the specific condition. The patient has recently experienced one blow from the original trauma and two blows from the surgical trauma, and was severely damaged psychologically, so it was difficult to accept the fact of another surgery, so he sought medical advice, read advertisements and paid attention to various clinics, thinking that he could be cured by spending money. So they had to undergo surgery, and the time, energy and money they had spent before went down the drain, and the whole family was completely impoverished. If we can receive further treatment early, we can take care of ourselves completely in 3 weeks, freeing our family and ourselves, and the whole family will be able to make a beautiful turnaround from poverty to wealth sooner.
