Objective:
To evaluate the feasibility, safety, and efficacy of vessel-plasty using bone-filling mesh container (BFMC) for malignant severe compression fractures of cervical vertebra.
Methods:
This study prospectively recruited fifteen consecutive patients (eight men, seven women; mean age, 57.4 years) with severe malignant compression fractures of cervical vertebrae for vessel-plasty. Procedure duration, incidence of cement leakage and other complications, pain relief and improvement of neck function were analyzed. Pain was assessed using a visual analog scale (VAS) and function by the neck disability index (NDI), with scores recorded before the procedure and at 3 days and 1, 3, 6 and 12 months after the procedure.
Results:
A total of 16 vertebrae were treated. All vertebrae had destruction of bone in more than one place as well as broken bone walls. Mean procedure duration was 42.9±13.6 minutes. Bone cement leakage occurred in two vertebrae without any symptoms. No procedure-related complications occurred. Mean VAS and NDI declined from 7.1 ± 1.4 and 63.6 ± 16.3, respectively, before the procedure to 3.5 ± 1.1 and 37.4 ± 11.0, respectively, at three days after the procedure (P < 0.01). CT images at three months after the procedure confirmed that there were no cases of refractures at the treated or adjacent levels, recurrence of vertebral collapse and mobilization of bone cement block.
Conclusion:
Vessel-plasty using BFMC appears to be effective and safe for malignant severe compression fractures in cervical vertebrae. It is effective in stabilizing vertebral body, relieving pain.
