Modifications dégénératives des articulations facettaires dans les suites de vissages pédiculaires percutanés sans arthrodèse - 06/05/15
Degenerative facet joint changes in lumbar percutaneous pedicle screw fixation without fusion
Abstract |
Background |
Aim of the study was to evaluate degenerative lumbar facet joint changes after percutaneous pedicle screw fixation (PPSF) in the treatment of lumbar fractures.
Patients and methods |
Thirty patients underwent short PPSF without fusion. CT scan was performed in the pre- and postoperative time at 4, 8 and 12 months. The 6 zygapophyseal joints adjacent the fracture's level were evaluated.
Results |
At 4 months patients showed no differences between pre- and postoperative joint radiographic aspect. At 8 and 12 months CT scan demonstrated a progressive degeneration only in the middle joints respectively in 21.42% and in 76.92% of the cases. All 10 disrupted facet joints showed progressive degenerative changes at 8 and 12 months.
Conclusion |
Lumbar percutaneous fixation without fusion induces little degenerations essentially collocated in the middle joints close to fracture level at 8 and 12 months. In the proximal and distal joints adjacent the screws degenerative changes can be seen only when associated to pedicle screw encroachment.
Level of evidence |
Level IV, retrospective study.
