OBJECTIVE: To present the incidence and management of dural tears and @entity5173 during corrective osteotomy [Pedicle Subtraction Osteotomy (PSO) or Smith-Petersen Osteotomy (SPO)] for @entity1691 with @entity85 . METHODS: A retrospective study was performed for @entity1691 @entity1 with fixed sagittal imbalance, who had undergone corrective osteotomy (PSO or SPO) at lumbar level. 87 @entity1 were included in this study. 55 @entity1 underwent PSO, 32 @entity1 underwent SPO. The mean age of the @entity1 at the time of surgery was 41.7 years (21-70 years). Of the 87 @entity1 , 15 @entity1 had intraoperative dural tears. RESULTS: The overall incidence of dural tears was 17.2%. The incidence of dural tears during PSO was 20.0%, SPO was 12.5%. There was significant difference in the incidence of dural tears based on surgical procedures (PSO vs. SPO) (p<0.05). The dural tears ranged in size from 12 to 221 mm(2). A nine of 15 @entity1 had the relatively small dural tears, underwent direct repair via watertight closure. The remaining 6 @entity1 had the large dural tears, consequently direct repair was impossible. The large dural tears were repaired with an on-lay graft of muscle, fascia or fat harvested from the adjacent operation site. All @entity1 had a successful repair with no @entity1 requiring reoperation for the @entity5173 . CONCLUSION: The overall incidence of dural tears during PSO or SPO for @entity1691 with @entity85 was 17.2%. The risk factor of dural tears was complexity of surgery. All dural tears were repaired primarily using direct suture, muscle, fascia or fat graft.
