Percutaneous pedicle screw fixation plus kyphoplasty for thoracolumbar fractures A2, A3 and B2.

DESIGN

Retrospective cohort.

PURPOSE

The aim of this study is to evaluate the effectiveness of percutaneous short fixation (PSFx) plus kyphoplasty (BP) for thoracolumbar fractures.

METHODS

Thirty-six consecutive selected patients, aged 59 ± 17 years, with fresh single thoracolumbar A, A, and B 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 ± 7 months.

RESULTS

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.

CONCLUSIONS

PSFx plus BP for thoracolumbar fractures reduces significantly spinal deformity and pain with few complications.
