Abstract: Although osteoporotic and neoplastic fractures
are main indications to vertebroplasty or kyphoplasty, it has
been recently suggested that the latter procedure can be a
safe and effective treatment also in appropriate patients with
traumatic injuries, retaining its advantages in terms of early
mobilization. Our results, gathered so far in patients offered
the option between kyphoplasty and traditional conservative
treatment in real-life clinical settings, are reported here.
From June 2005 to September
2007, 24 hospitalized subjects (age:18-76 yrs.; M: 19, F:
5) agreed to undergo kyphoplasty because of a suitable
traumatic injury. Specifically, Magerl type A fractures not
requiring surgery and involving the spine from T5 through
L5 in a non-comatose patient. As cortical bone is usually
violated, technique was modified in order to allow for
coverage of defects by repeated injections of small amounts
of dough-like cement before filling up the bone cavity.
Preoperatively, CT scan was performed and standing radiographs obtained to assess vertebral deformity, while clinical data were supplemented by Visual Analog Scale (VAS)
pain rating. All of the above were repeated after kyphoplasty.
Follow-up evaluations were scheduled at 1, 3, 6, 12
and 24 months.
Early mobilization (on the 2nd post-op day) was
obtained in all patients, as well as pain relief (baseline VAS
score: 7.8 95% CI 7.4-8.2; 48-hr post-op: 1.4 95% CI
0.9-1.9). Radiographic improvement was only slight or
moderate. In 6 subjects, limited amounts of cement leakage
were spotted. No clinical complications occurred.
As it has been already pointed out, conservative
therapy of vertebral fractures is neither benign nor
risk-free as the term seems to imply. Our data are in keeping
with those previously reported that percutaneous vertebral
augmentation can produce immediate improvement in a
patient’s quality of life. On the other hand, not all of the
traumatic spine fractures are suitable for such a procedure
but only those with a lower destruction level of the vertebral
body. Careful injection technique, in a bone cavity previously
remodelled by inflatable bone tamp, can minimize
cement leakage and forestall complications.
