PURPOSE: The treatment of @entity1635 is a challenge especially in @entity1 over 50  years old with severe, rigid curves in whom the use of @entity3574 may be necessary to correct the deformity. The aim the study was to analyse the perioperative complications related to @entity3574 in elderly treated for @entity85 . METHODS: We analysed 72 consecutive cases of @entity3792 , we classify them according to Berjano-Lamartina classification. We divided @entity1 into two groups: we only practised SPO and/or PO in @entity1 that composed group A; we practised also PSO in @entity1 that composed group B. We retrospectively analysed the perioperative complications and radiographical results. Average follow-up was 30  months. RESULTS: We had 50 cases of @entity179 ( @entity179 ) Type III, 13 Type IVa @entity179 and 9 Type IVb @entity179 . Mean age was 60.7  years old. Overall complication rate was 22.2  %. In group A, the complication rate was 16.9  % while in group B it was 46.2  %. Mean Cobb primary curve angle was 41.75   with average C7 plumb line (C7PL) of 4.49  cm, residual scoliosis after surgery was 15.41   and average C7PL of 2.08  cm, with statistically significant differences. CONCLUSIONS: Previous studies have shown increased complication rates with @entity3574 in elderly @entity1 , our experience support this evidence. Our study demonstrates a high incidence of intraoperative complication rate in elderly @entity1 underwent a PSO. PSO is a demanding technique to be considered in very selected and motivated @entity1 who must be carefully informed about the risks of the procedure.
