Introduction:
For patients with acetabular osteolytic metastases involving the articular surfaces, current treatments cannot efficiently rebuild the acetabular bone frame structure and strengthen bone defect area mechanics for weight-bearing. The purpose of this study is to show the operational procedure and clinical outcomes of multisite percutaneous bone augmentation (PBA) for the treatment of incidental acetabular osteolytic metastases involving the articular surfaces.
Methods:
According to the inclusion and exclusion criteria, 8 patients (4 males and 4 females) were included in this study. Multisite (3 or 4 sites) PBA was successfully performed in all patients. The pain and function evaluation and imaging observation were examined by VAS and Harris hip joint function scores at the different time points (pre-procedure, 7 days, one month, last follow-up in 5-20 months).
Results:
There were significant differences (p<0.05) in VAS and Harris scores before and after the surgical procedure. Moreover, these two scores had no obvious changes during the follow-up process (7 days after the procedure, one month after the procedure, and the last follow-up) after the procedure.
Conclusion:
The proposed multisite PBA is an effective and safe procedure for the treatment of acetabular osteolytic metastases involving the articular surfaces.
