Abstract:

BACKGROUND: Comparison of perioperative complications between simultaneous and staged bilateral total hip arthroplasty remains controversial.
OBJECTIVE: To compare the rates of perioperative complications in patients undergoing simultaneous or staged bilateral total hip arthroplasty and evaluate the safety of simultaneous total hip arthroplasty
METHODS: A total of 112 cases undergoing primary bilateral total hip arthroplasty were retrospectively analyzed, including 81 of simultaneous and 31 staged bilateral total hip arthroplasty. A total of 31 patients of age and sex matched were selected from simultaneous group to compare with staged group. Rate of perioperative complications of two groups was compared.
RESULTS AND CONCLUSION: No significant differences between the two matched groups were detected with regard to preoperative complications (P > 0.05). The percentage of patients who had cardiovascular and cerebrovascular complications was significantly higher in the simultaneous group than in the staged group (P < 0.05). Preoperative health status must be assessed carefully. Patients must be fully informed the risks of simultaneous bilateral total hip arthroplasty before surgery. Active prevention of perioperative complications should be applied after surgery．
