Abstract: BACKGROUND: The incision of anterolateral approach for femoral head replacement is larger; the cut muscle needs time to heal; and the recovery time is longer. The incision of the SuperPATH approach is very small, and it does not cut off the muscle, so it can recover quickly. However, it needs special artificial prosthesis and special instruments, and the cost is high.  
OBJECTIVE: To compare the efficacy of conventional instrument SuperPATH approach and anterolateral approach for femoral head replacement.
METHODS:  From December 2016 to August 2018, 43 elderly patients with femoral neck fracture were randomly divided into experimental group (21 cases, SuperPATH group) and control group (22 cases, anterolateral group). All patients were operated with conventional instruments and femoral head, The incision length, intraoperative blood loss, the time from skin incision to incision closure, the changes of hemoglobin and red blood cells before and after operation, the time of getting off the ground after operation, pain score and hip joint function score were recorded.  
RESULTS AND CONCLUSION: All patients were followed up for 24 to 36 months. Among them, the length of incision, the time from skin incision to incision closure, the time to get off the ground after operation, Visual Analogue Scale score at 1 week, Harris score at 1 week and 3 months after operation were significantly different between the two groups (P < 0.05), and the experimental group was better than the control group. There was no significant difference in blood loss during operation, changes of erythrocytes and hemoglobin before and after operation, Visual Analogue Scale score at 3 months after operation and Harris score at 6 months after operation between the two groups (P > 0.05). These findings confirm that compared with anterolateral approach, SuperPATH approach has the advantages of shorter incision, less trauma and faster recovery.
