Abstract
Retrospective cohort. The aim of this study is to evaluate the effectiveness of percutaneous short fixation (PSFx) plus kyphoplasty (BP) for thoracolumbar fractures. Thirty-six consecutive selected patients, aged 59±17years, with fresh single thoracolumbar A2, A3, and B2 AO-type fracture, received PSFx plus BP. The primary outcomes pain, and vertebral body deformity; and the secondary outcomes screw malposition, facet violation, PMMA leakage, adjacent segment degeneration (ASD) and loss of correction were evaluated. The f/up was 31±7months. Pain and kyphosis decreased and vertebral body heights increased significantly postoperation. PMMA leakage occurred in five cases; 6 (4%) screws were grades III malpositioned in relation to pedicle; facet violation occurred in 8 (5.5%) facets; loss of kyphosis correction was 3.68°; ASD occurred in two cases; interfacet fusion in ten (28%) patients; Three patients were reoperated for different reasons. PSFx plus BP for thoracolumbar fractures reduces significantly spinal deformity and pain with few complications.
