ObjectiveTraumatic femoral neck fracture is a common disease that can be treated by hip arthroplasty, which is divided into hemiarthroplasty (HA) and total hip arthroplasty (THA). The difference between HA and THA are incompletely understood. The objective of this study was to investigate the effect of hip arthroplasty on hip function in patients with traumatic femoral neck fracture.MethodsA total of 132 patients with traumatic femoral neck fracture admitted to our hospital from January 2019 to January 2021 were selected and divided into control group (HA group) and study group (THA group) with 66 cases in each group by random number table method. The duration of operation, intraoperative blood loss, postoperative drainage and length of hospital stay were compared between the two groups. The degree of pain before operation, 3 days after operation and 7 days after operation were observed, the hip joint function before operation, 6 months after operation and 12 months after operation was analyzed, and the occurrence of short-term and long-term complications was compared between the two groups.ResultCompared with the HA group, the operative time, intraoperative blood loss, postoperative drainage and hospital stay were higher in the THA group. The degree of pain in THA group was higher than that in HA group on 3 and 7 days after operation; At 6 and 12 months after surgery, the scores of pain, range of motion, joint function and deformity in the THA group were higher than those in the HA group with statistically significant. Compared with HA group, IGF-1 and Leptin in THA group were increased significantly, while inflammatory cytokines TNF-α was decreased in THA group. The total incidence of short-term and long-term complications was lower in THA group.ConclusionTotal hip arthroplasty can effectively restore hip joint function in patients with traumatic femoral neck fracture, with low incidence of short-term and long-term complications, high safety, and worthy of clinical application.© 2022.
