Objectives: Vertebroplasty for vertebral compression fractures is a reliable method with very low rate of operative complications. For high risk patients, the surgery is priority choice. The purpose of this study was to investigate the clinical post-operation data follow-up and re-operation after vertebroplasty.
Methods: This is a retrospective study to assess clinical outcome 515 patients (710 levels, avg. 72.67 years) vertebral compression fractures treated with vertebroplasty from Jan. 2002 to Nov. 2010. We compared the pre- and post-operative Oswestry Disability Index, pain score (VAS) and investigate the re-operation of those patients.
Results: 49 patients (F/M: 47/2, avg. T-score of lumbar spine BMD: -3.32, the avg. BMD of 466 no-reoperation patients: -2.12) had reoperation (second: 39 patients; 3rd: 6 patients; 4th: 3 patients; 5th:1 patient) were included in this study, and total 141 levels accepted operated. 13 segments (14.1%) were second operated in same level (8 levels with vertebroplasty and 5 levels with kyphoplasty). 29 segments (31.5%) were opened on adjacent segment. At surgery interval, 3 kinds of reoperation locations (same, adjacent, and other segment) were avg. 526.69, 587.07 and 657.84 days. Excellent and good (78.6%) clinical results were obtained after operation. The mean of VAS improved significantly from 7.2 to 1.9 after surgery.
Conclusions: Mid-term follow-up, we had the special found the rate of reoperation(9.5%) was lower than other scholar's studies, the patient accepted re-operation almost were female (47/49) and T12 reoperation (33%) was usual happen. Maybe be caused by faulty posture, and the spine is the humpbacked found by X-ray. In addition, we found the patient BMD less than -2.5 increased the risk of reoperation, and the same segment reoperation was short at surgery interval. However, vertebroplasty are usually successful at alleviating the pain; many patients feel significant relief almost immediately. Many patients become symptom-free.
