|
| Shunwu et al. (2010) [9] | Prospective cohort study | 24–42 months | 32 (MI), 30 (O) | MI: reduced blood loss, les postoperative back pain, lower serum creatine kinase, shorter time to ambulation, and shorter LOS |
|
| Wang et al. (2010) [7] | Prospective | Minimum 13-month follow-up | MI = 42, O = 43 | MI: reduced blood bloss, less postoperative back pain, shorter LOS, greater radiation time |
