Purpose

the aim to study was to evaluate the effectiveness of nitinol endovertebral implant assisted vertebroplasty in the treatment of ostheoporotic vertebral fractures by means of pain reduction and height reastauration.

Methods & Materials

from February to May 2010 ten consecutive patients (3 male, 7 female, average age: 69,7) with painful ostheoporotic vertebral fractures underwent nitinol endovertebral implant assisted vertebroplasty(VerteLift®, SpineAlign Medical, USA). Patients had been previously evaluated with clinical examination and with X-Ray, CTms and MRI T2w STIR. All the procedures were executed with local anaesthesia with bilateral approach under digital fluoroscopic guidance. After the working cannulas were inserted, two Nitinol endoprosthesis (16 or 18mm, symmetric or asymmetric) were expanded within the vertebral body; bone cement (PMMA) was then injected under fluoroscopic control. A total of 12 vertebras was treated. Clinical evaluation, assessment of pain by mean of a11-points visual analogue scale (VAS, 0-10) and of function by means of the Oswestry disability scale(ODI 0-100%) was performed at baseline and at one month after the procedure. Height restauration by mean of volume calculation with CTms was made before and after the procedure.

Results

we have obtained a progressive reduction of the pain in all the patients (Av. VAS pre: 7.8, post 3.0, difference: 4.7), an improvement of function(ODI baseline: 50.6%, at 1M: 24.4%, difference: 26.2%) a good restoring of the height (Av. h pre: 217mm, post: 200mm, difference: 17mm), and a good increasing of the volume of the vertebral bodies (Av. V pre: 26.9cm3, post: 24.6cm3, difference: 3.3cm3). No complications arose, neither device migration was noted.

Conclusion

from our preliminary studies the implant of VerteLift® resulted to be safe and effective in the treatment of painful ostheoporotic vertebral fractures.
