M. Yanase et al., TRANSPEDICULAR FIXATION OF THE LUMBAR AND LUMBOSACRAL SPINE WITH SCREWS - APPLICATION OF THE DIAPASON SYSTEM, Paraplegia, 33(4), 1995, pp. 216-218
Forty-six patients with the Diapason transpedicular screw system for l
umbar and lumbosacral fusions were analysed clinically. No implant bre
akage was observed, but one rod migrated. Additional sacral screws dif
ferent in the length of the threaded portion are necessary in this sys
tem. Metallosis was noted in a few cases, but posed no significant cli
nical problems. This system, which is simple in structure, easy to use
, and applicable to magnetic resonance scanning after surgery, is cons
idered to be a useful instrumentation.
