This study aims to compare the surgical outcomes and complications between kyphosis and kyphoscoliosis when using three-column osteotomies. The doctors have reviewed adult spine deformity or ASD patients with three main column osteotomies between March 2005 and December 2014. Pre- and postoperative standing posteroanterior and lateral radiographs of the entire spine were obtained. Scoliosis Research Society-22 questionnaire [SRS-22] and Oswestry Disability Index [ODI] were administered preoperatively, postoperatively (surveys within two months after surgery), and at final follow-up. Patients were assigned to one of two groups according to preoperative coronal curve magnitude: if coronal curve <10°, patients were assigned to kyphosis group; if coronal curve >40°, patients were assigned to kyphoscoliosis group.
33 ASD patients were assigned to the kyphosis group, of which 26 received PSO and 7 VCR. Seventy-six patients were assigned to the kyphoscoliosis group, of which 50 received PSO and 26 VCR. Patients in the K group were significantly older than in the S group (42.8 vs. 33.7 years, p < .05). Significantly longer OT (operation time) and more estimated blood loss were observed in the S group as compared to the K group (OT: 282 vs. 205 min, p < .05; EBL: 1827 vs. 1214ml, p < .05). The doctors noticed no significant difference in the number of fusion levels between the groups. Pre-operative radiographic parameters demonstrated no difference of GK global kyphosis and SVA or sagittal vertical axis between the two groups.
