Background: To report on the technique and results of parallel endplate osteotomy (PEO) for severe rigid spinal deformity.Methods: Between July 2016 and December 2018, 36 patients with severe rigid spinal deformities who underwent PEO were retrospectively reviewed after a minimum follow-up of 24 months.Results: Following PEO, the kyphosis and scoliosis correction rates reached 77.4 ± 14% and 72.2 ± 18.2%, respectively. The median intraoperative estimated blood loss was 1500 mL and the operative

The SF-36 scores of physical function, role-physical, bodily pain, general health, vitality, social function, role-emotional and mental health changed from 62 ± 28, 51 ± 26, 49 ± 29, 35 ± 30, 53 ± 28, 45 ± 30, 32 ± 34 and 54 ± 18 at baseline to 81 ± 16, 66 ± 41, 72 ± 40, 64 ± 44, 75 ± 25, 71 ± 46, 66 ± 34 and 76 ± 28 at one year postoperatively , 82 ± 32, 67 ± 42, 81 ± 30, 71 ± 41, 80 ± 30, 74 ± 36, 68 ± 35 and 85 ± 33 at 18 months postoperatively, and 86 ± 21, 83 ± 33, 88 ± 26, 79 ± 39, 86 ± 36, 86 ± 48, 80 ± 47 and 91 ± 39 at 24 months postoperatively, respectively. Conclusions: PEO is an effective technique for successful correction of spinal deformities. At the two year follow-up visit, all patients achieved better clinical results based on the SF-36 scores.
