Residual mobility after removal of instrumentation in patient, with type a2-a3 vertebral fractures, treated with percutaneous pedicle screw fixation.

SOCIETA' ITALIANA CHIRURGHI ORTOPEDICI DELL'OSPEDALITA' PRIVATA ACCREDITATA, Proietti L, Perna A, Schirò GR, Noia G, Fumo C, Tamburrelli FC Abstract Percutaneous techniques for treatment of thoraco-lumbar fractures type A2 and A3 are widely used. These techniques are considered temporary fixations and instrumentation must be removed with fracture healing. The aim of the study is to analyze clinical results, motility of treated segments and any loss of correction after the removal of instrumentation. We evaluated 36 patients who underwent surgery for removal of the instrumentation. Standard and dynamics x-ray before surgery and at 1 and 12 months after surgery were obtained. Radiographic evaluation was performed by comparing loss of correction after removal of the instrumentation, residual mobility of fractured vertebra, upper and lower level with values defined by Dvorak. For clinical assessment were used SF-12, Oswestry Disability Index (ODI) and Visual Analog Scale (VAS), administered before surgery and at 1 and 12 months after the removal. We analyzed a total of 108 levels in 36 patients. After removal of the instrumentation a normal range of motion was restored in the prox...
