Aim of the study: Impaction bone grafting is examined and published by numerous authors in the literature, however possible correlation between bone remodeling at the site of revision hip arthroplasty and bone turnover markers is not well known yet.

Materials and method: 22 patients undergoing revision hip arthroplasty with impaction bone grafting were enrolled in a prospective study. Bone turnover markers and bone mineral density (DXA) were measured preoperatively. WOMAC and Harris Hip Score (HHS) were evaluated pre- and postoperatively. During a one-year-period the same tests were performed after 6 weeks, 3 months, 6 months, 12 months respectively. The data were analyzed using logistic regression.

Results: Significant bone remodeling was observed at the site of revision hip arthroplasty at the 6 month follow up. WOMAC and HHS improved significantly after surgery. One deep wound infection occurred due to MRSE, removal of the prosthesis was performed.

Conclusion: Cancellous bone grafting secures primary stability for the hip implants, and after a period of 12 months proper bone remodeling is achieved.
