But with more than ten years of experience and summarize, more and more feel the importance of physical examination and history taking, now on the recent case of a patient’s diagnosis and treatment description: the patient is a 60-year-old man, initially and my contact is through a friend, said that the pain in the lower back, asked me to prescribe some medication, I follow my diagnostic and treatment habits, suggested that he come to the outpatient clinic or to my hospital room to see what the situation is, the result is that a week later in my checkup, he was his own children with a wheelchair pushed to me, and I will be in a wheelchair, and I will be in a wheelchair. I was very surprised, I asked him if the pain was very serious, he said it was very serious, he could not walk, I let him get up from the wheelchair and walk around, the result was to find that both his hips can not stand up straight, the step can not be open, I realized that there may be a problem with the hip joints, so let him lie down to carry out a routine physical examination, and found that the mobility of his hip joints is very small, and began to ask for a history of the disease, he said that there is a pain in his hip joints. There are 10 years, went to some hospitals to see, are said to be the elderly, back is not good, the pain with medication can be, the result is slowly can not squat, planting rice are kneeling in the field, this history shows that his joint activities have been limited, so turn over his imaging data, from the lumbar spine film found that the hip joint has reached the standard of osteoarthritis, deformation of the head of the femur, and so give him an additional pelvic film. He was given an additional pelvic film, which proved bilateral femoral head necrosis with osteoarthritis of the hip joints, and he was given a double hip replacement. If I had prescribed medication at his request, he might have continued to work on his knees in the field.
