The patient in the case is an 83-year-old grandmother Zhang, who fell and caused a femoral head fracture with significant fracture displacement, which was diagnosed as a left femoral neck fracture (subhead type) after examination. Although the patient was old, there was no contraindication to surgery. The patient gradually returned to normal walking after the artificial joint replacement and was satisfied with the surgical result. [Basic information] Female, 83 years old [Disease type] Left femoral neck fracture (subhead type) [Hospital] The First Hospital of Harbin Medical University [Consultation time] January 2022 [Treatment plan] Surgery (artificial joint replacement) + medication (low molecular weight heparin calcium injection + injectable parecoxib sodium) [Treatment period] Hospitalization for 14 days [Treatment effect] Walking gradually returned to normal. In winter, the road is cold and slippery, and if you are not careful, you will fall. The patient was immediately sent to the emergency room by her family. The examination revealed that the left lower limb was significantly rotated outward compared with the right side, and the left toe was turned to the outside at about 45°, which is a typical manifestation of femoral head fracture. X-ray examination confirmed the diagnosis of femoral head fracture, and the fracture line was located just under the left femoral head, and the fracture end was obviously displaced, and the patient was finally diagnosed with left femoral neck fracture (subhead type). II. Treatment history The femoral neck fracture was difficult to heal, so the patient and his family decided to be admitted to the hospital for surgical treatment. After admission, the patient was given skin traction on the lower extremity in order to control the movement of the fracture end and relieve pain. The traction was accompanied by subcutaneous anticoagulation with low-molecular-weight heparin calcium injection and analgesic treatment with injectable parecoxib sodium. Further preoperative tests such as electrocardiogram, cardiac ultrasound, chest X-ray, lower extremity vascular ultrasound, routine blood count, liver and kidney function, and additional CT scan at the femoral neck fracture were subsequently completed. On the 4th day after admission, the patient underwent artificial joint replacement with regular postoperative incision care and stitches were removed 2 weeks after surgery. III. Treatment results The operation went smoothly, and the patient was wheeled back to the ward in about 1 hour. On the day after the operation, the patient’s hip pain was significantly relieved and the joint resumed voluntary movement. On the third day after the operation, the patient started to practice getting off the bed with the support of his family. At the end of 14 days of hospitalization, the patient was able to walk on his own with the help of the wall and had no other uncomfortable symptoms, so he was discharged from the hospital. Precautions We are glad that the patient can start to leave the bed early after the artificial joint replacement surgery, but there are many precautions after the replacement surgery, mainly the following: 1. Patients need to be watched when moving around to avoid fracture again after a fall; 2. Patients should not have too large a range of joint movement, and should not do dangerous movements such as cross-legged and stilted legs to prevent joint dislocation; 3. If fever or wound infection occurs, antibiotics should be applied promptly; 4. If abnormalities such as redness, swelling, pain or deformity are found in the joint, seek medical attention promptly. V. Personal insight Since the femoral head is located in the joint, most of its own blood supply depends on the femoral end, so once the fracture is poor, it is one of the more difficult types of fractures to heal after fracture. In this case, the patient was not only older, but also had more difficulty in healing the subtrochanteric femoral neck fracture. At this time, most physicians would recommend surgical joint replacement, and it was more difficult for the patient and his family to decide whether or not to undergo surgery, so the patient and his family should be informed of the importance of surgery.
