Retrospective analysis on simultaneous bilateral total hip arthoplasty in 93 patients / 中华创伤杂志

ABSTRACT

Objective To retrospectively study the perioperative complications and postoperative function recovery of 93 patients treated with simultaneous bilateral total hip arthroplasty (THA). Methods A total of 93 patients (186 hips) undergone simultaneous bilateral THA from January 1999 to January 2009 in our hospital were involved in this study. There were 70 males and 23 females (at age range of 25-65 years, average 41. 8 years). The preoperative diagnosis included bilateral avascular necrosis of femoral head in 48 patients, rheumatoid arthritis in 11, developmental dysplasia of the hip in 26 and ankylosing spondylitis in 8. The intraoperative blood loss, Harris scores before operation and at final followup as well as perioperative complications were analyzed. Results All the patients were followed up for average 65 months (12-118 months), which showed femur fracture in one patient and infection six months after discharge in one patient. The Harris score was increased from (36.7 ±6.1) points preoperatively to (91.2±6.2) points at the final follow-up. Hip pain disappeared in 92 patients after operation and radiograph showed no loosening. Actebular loosening occurred in one patient 49 months after operation and was revised accordingly. Conclusion Under strict control of operation indications, suitable choice and implantation of the prosthesis and emphasis on perioperative management and postoperative rehabilitation, simultaneous bilateral THA is a safe and effective choice for bilateral hip diseases.
