Auntie Yang was born in 1911 and is 101 years old this year. Recently, she slipped and fell while walking at home, causing swelling and pain in her right hip and limiting her activities. She was diagnosed with a comminuted fracture of the right femoral trochanter after an examination at our hospital. After meticulous preoperative examination and preparation, the patient underwent closed reduction PFNA internal fixation of the right femoral trochanter fracture on the third day after admission. The patient started to walk with a walker about 5 or 6 days after surgery. When the patient was followed up at home again one month after surgery, Auntie Yang was able to walk with full weight without the help of a walker. The patient and her family were very satisfied with the results of the treatment. Fractures of the ramus are quite common in the elderly, and the treatment can be broadly divided into conservative and surgical treatment. For such an elderly patient, if conservative treatment such as bone traction is chosen, the patient will be bedridden for too long, and various complications such as sacrococcygeal decubitus, lung infection, and deep vein thrombosis of the lower extremity will appear one after another. Surgery means that the patient will be able to go to the ground soon. Therefore, the significance of surgery is undoubtedly great. In the past, such surgery was performed on an orthopedic traction bed, and some patients had obvious postoperative swelling of the limb, and others had knee pain after surgery due to prolonged stretching of the knee ligaments, which had some impact on early landing. In the past 2 years, the Department of Surgery of our hospital has been performing this surgery in the lateral position.
