ABSTRACT
AIM:
To evaluate the efficacy of percutaneous vertebroplasty (PVP) combined with interventional tumor removal (ITR) in providing pain relief, reducing disability, and improving functional performance in patients with malignant vertebral compression fractures without epidural involvement.METHODS:
Patients with malignant vertebral compression fractures (n=58) were treated with either PVP+ITR (n=31, group A) or PVP alone (n=27, group B). A 14 G needle was inserted into the vertebral body, and the tract was sequentially dilated with working cannulae. When the last working cannula had reached the distal pedicle of vertebral arch, ITR was performed with a marrow nucleus rongeurs inserted through the working cannula. Finally, cement was injected into the excavated vertebral body. Patients were followed up at 1, 3, and 6 months after the procedure, and every 6 months thereafter.RESULTS:
The overall excellent and good pain relief rate during follow-ups was significantly better in group A than in group B (94% vs.56%; p=0.002). The average VAS, ODI, and KPS scores at 3 months, 6 months, 1-year, and >1 year were all significantly lower in group A than in group B (p<0.05). The mean cement filling volume and the stability of the treated vertebrae were significantly higher in group A than in group B (p<0.05).CONCLUSIONS:
The combination of PVP+ITR is a safe and effective procedure, capable of providing significantly greater pain relief and vertebral stability than PVP alone in patients with malignant vertebral compression fractures.
