Until now it was postulated - without
scientific verification - that patients with VEPTR (vertical
expandable prosthetic titanium rib) treatment get later and less
ossifications than children with growing rod treatment because of
the lower manipulation at the spinal column. This study is
performed to evaluate the ossification rate, time of onset of
ossifications, magnitude of ossifications in the course of
treatment, correlations for the occurrence of ossifications for
putative factors (underlying disease etc.) and potential
consequences of ossifications in patients with VEPTR treatment.
Fifty-seven patients had a primary longitudinal lengthening with
use of a chest-wall distractor known as VEPTR. Repeat lengthenings
of the prosthesis were performed at intervals of three to fourteen
months. The mean age at the time of the primary operation was 7.7
years (range 1.3 to 18.3), the mean duration of follow-up was 29.8
months (range 1 to 101) and the mean number of operations was 5.9
(range 1 to 19). 1328 spine radiographs were analyzed with respect
to the growth of ossifications and implant-migration respectively
-avulsion and other complications/radiological parameters. The
digital radiographs were measured with Centricity2013-06-2
