Safety and Effectiveness of the Anchor Augmentation with Bone Cement on Osteoporotic Femoral Fracture: A Systematic Reviews

Financial support: This study was supported by research funds of the Ministry of Health and Welfare. Conflict of interests: None. Purpose: This paper reviewed the safety and effectiveness of anchor augmentation with bone cement in osteoporotic femoral fractures. Materials and Methods: A systematic review was conducted by searching multiple databases including five Korean databases, Ovid-MEDLINE, Ovid-EMBASE, and Cochrane Library. Safety was assessed through the incidence of complication. The effectiveness was assessed through the failure rate of anchor fixation, improvement of function and radiological assessment (sliding distance of lag screw and cutout). The safety and effectiveness of anchor augmentation with bone cement were assessed by reviewing all articles reporting on the treatment. Two researchers carried out independently each stage from the literature search to data extraction. The tools of Scottish Intercollegiate Guidelines Networks were used to assess the quality of studies. Results: Six studies were considered eligible. The safety results revealed a small amount of cement leakage (1 case), but no other severe complications were encountered. Regarding the effectiveness, the failure rate of anchor fixation was 16.7% and the Harris’s hip score showed no significant improvement. The sliding distance of the anchor was similar in the cement augmentation group and noncement group but there was no cutout. Conclusion: The results of the assessment suggest that the safety is acceptable, but further research will be needed to verify the effectiveness of the treatment.
