Abstract:

BACKGROUND: There is no uniform method to repair mild and moderate femur bone defects during hip revision.
OBJECTIVE: To evaluate the clinical outcomes of uncemented all-coated long stem prosthesis in mild and moderate femur bone defect during hip revision.
METHODS: Eleven patients had mild and moderate femur bone defects after primary hip arthroplasty, they all received uncemented all-coated long stem prosthesis treatment. Among the 11 patients, 8 patients underwent dried bone allograft particles.
RESULTS AND CONCLUSION: All the incisions healed by the first intension. All patients were followed up for 10-60 months. There was significant difference in the mean Harris score between preoperation and postoperation (P < 0.01). X-ray examination showed that continuous radiolucent line of 3 mm occurred in 1 case, and no clinical symptoms were observed. Eight cases with dried bone allograft particles recovered within an average period of 5 months (3-9 months). The uncemented all-coated long stem prosthesis can provide initial stabilization in repair of mild and moderate femur bone defects during revision hip arthroplasty, and the short-term clinical effects are satisfactory.
