Table 3.
Quality of life (QoL) and main clinical and functional outcomes. FS: functional scale; NRS: numeric rate scale; ODI: Oswestry disability index; OPF: open posterior fusion; PO: percutaneous osteosynthesis; QLQ-BM22: bone metastases module; SS: symptom scale. Regarding the QLQ-BM22 functional scales, the scores span from 0 to 100, with higher scores indicating an improved quality of life. As for the QLQ-BM22 symptom scales, the scores also range from 0 to 100, but higher scores signify more severe symptoms.
