Preliminary Result of THA Using Interface Bioactive Bone Cement Technique Combined with Third Generation Cementing Technique

29 cases of primary total hip arthroplasty (THA) using interface bioactive bone cement technique (IBBC) combined with third generation cementing technique were evaluated clinically and radiologically. The present study includes 2 men 2 cases and 24 women 27 cases with an average age at operation of 63 years old (ranging 42 to 81). Mean postoperative follow up period was 17.3 months (ranging 12 to 23 months). Pre- and postoperative (1 year) evaluation using Japan Orthopaedic Association (JOA) hip score were 36.0, and 85.0 points, respectively. Postoperative cementing grade using Barrack’s classification was A in every case. At one year, radiolucent line at bone-cement interface was not observed, except one case of rheumatoid arthritis patient at zone 3 (Delee and Charnley) in the acetabular side. Neither osteolysis nor loosening was observed in every case. No major complications, such as infection, dislocation, pulmonary embolization, were observed. The present study revealed excellent short-term result was obtained by IBBC technique combined with third generation cementing technique for primary THAs.
