Objective: To explore the percutaneous hollow screw internal fixation combined with cementoplasty in the treatment of periacetabular metastasis. Methods: A retrospective study was performed on 16 patients with periacetabular metastasis who were treated with percutaneous hollow screw internal fixation combined with cementoplasty between May 2020 and May 2021. There were 9 males and 7 females. The age ranged from 40 to 73 years, with an average of 53.6 years. The tumor involved around the acetabulum, and 6 cases were located on the left and 10 cases on the right. Operation time, frequency of fluoroscopy, bed rest time, and complications were recorded. Before operation, and at 1 weeks, 3 months after operation, the visual analogue scale (VAS) score was used to evaluate the pain degree, the short-form 36 health survey scale (SF-36) score was used to evaluate the quality of life. At 3 months after operation, the Musculoskeletal Tumor Society (MSTS) scoring system was used to evaluate the functional recovery of patients. During follow-up, the loosening of internal fixator and bone cement leakage were observed by X-ray film. Results: 0.05). At 3 months after operation, the MSTS score ranged from 9 to 27, with an average of 19.8. Among them, 3 cases were excellent (18.75%), 8 cases were good (50%), 3 cases were fair (18.75%), and 2 cases were poor (12.5%). The excellent and good rate was 68.75%. And 11 patients returned to normal walking, 3 had mild claudication, and 2 had obvious cl...
