Abstract:

BACKGROUND: The number of complications after hip replacement, such as infection, implant loosening, fracture prosthesis wear, osteolysis, and recurrent dislocation, had drastically increased. These complications would induce the increased occurrence of total hip revision.
OBJECTIVE: To analyze the causes and treatment measures of revision after total hip replacement.
METHODS: The reasons for revision, the prosthesis selection, the treatment of bone defect and the postoperative rehabilitation were discussed in 33 cases after total hip replacement. The prosthesis for revision included general metal ring and lining (21 cases), large head and cup (8 cases), polyethylene cup (4 cases), general femoral components (15 cases, including 11 cases fixed by bone cement), and lengthening femoral components (18 cases, including 9 cases fixed by bone cement and 6 cases of combined components).
RESULTS AND CONCLUSION: All 33 patients were followed up for 24-60 months, averagely 36.5 months. After revision, wound healed perfect, and the prosthesis was reliable. No case suffered from infection or dislocation. Hip joint function was greatly improved. Harris score was increased from 37.1 preoperatively to 91.3 postoperatively. Medium- or short-period clinical follow-up results demonstrated that if the indication of revision was right, bone defects were handled perfectly, prosthesis was chosen correctly, one-stage total hip revision can get a good clinical efficacy.
