Objective
To investigate the difference in clinical outcomes between total hip arthroplasty (THA) and hemiarthroplasty (HA) in patients with femoral neck fracture.
Method
To retrospectively analyze 96 patients (96 hips) with femoral neck fracture treated in our hospital and distinguish them into THA group (50 patients with 50 hips) and HA group (46 patients with 46 hips) according to the difference of their chosen surgical procedure, and to compare the difference in perioperative indexes, postoperative hip function, occurrence of near and long-term complications, long-term imaging performance, and revision rate between the two groups.
Result
The operating time, intraoperative blood loss, and total drainage were greater in the THA group than in the HA group (P < 0.05). At 6 months after surgery, the Harris score of the hip joint was higher in the HA group than in the THA group. At 3 years after surgery, the Harris score was higher in the THA group than in the HA group (P < 0.05). At 3 years after surgery, the excellent hip function rates were 86.00% and 67.39% in the THA and HA groups, respectively, with statistically significant difference between the groups. The incidence of long-term complications was significantly lower in the THA group than in the HA group (P < 0.05). The anteversion and abduction angles of patients in the HA group were smaller than those in the THA group at 6 months after surgery (P < 0.05). The WOMAC scores of the THA group were better than those of the HA group at 3 years after surgery (P < 0.05).
Conclusion
Compared with hemiarthroplasty, total hip arthroplasty has a longer operative time and more postoperative bleeding, but the complication rate is relatively lower in the long term, and the patients have better long-term hip function recovery, so total hip arthroplasty is recommended for patients with femoral neck fracture with an expected survival time longer than 3 years.
