To investigate the long term benefit of respiratory function on spirometry following percutaneous vertebroplasty (PVP).

Subjects comprised 20 patients (20 women; mean age, 73 years; range, 65-85 years) who underwent PVP for the treatment of osteoporotic compression fractures. Respiratory function was assessed before, 1-3 days after and 1 month after PVP. Respiratory function was assessed in terms of percent forced vital capacity (%FVC) and percent forced expiratory volume in 1 s (FEV1.0%).

Mean %FVC was 86.6±20.6% before PVP, 87.6±15.7% 1-3 days after PVP and 92.8±15.6% ≥1 month after PVP. No significant differences between time points were noted. Mean FEV1.0% was 77.45±11.4% before PVP, 76.04±10.4% 1-3 days after PVP and 77.6±8.1% ≥1 month after PVP, and again no significant differences were identified. However, preoperative %FVC was abnormally low (≤80%) in 8 patients, and normalized postoperatively in 6 of these 8 patients (75%). Mean preoperative %FVC in these 8 patients was 64.6±10.3%, improving to 73.1±8.9% 1-3 days after PVP and to 82.7±16.2% ≥1 month after PVP, and a significant difference in %FVC was apparent between before and ≥1 month after PVP. Preoperative FEV1.0% was abnormally low (≤70%) in 3 patients, but did not improve postoperatively in any of these 3 patients.

PVP can improve restrictive ventilatory defect in patients with abnormally low function.
