The use of nitinol rods in stabilization of the lumbar spine for patients under 21 years
The outcomes of surgical treatment of 25 young patients with degenerative diseases of the lumbar
spine in two groups were compared in patients with nitinol rods (dynamic stabilization) without spondylodesis and with rigid lumbar fixation of titanium rods.
Men - 12, women - 13, the average age is 17.6 years (from 16 to 21 years). These patients are divided
into 2 groups depending on the stabilization method. Clinical and radiological results were monitored at
least 1 year after the operation.
In our study we used nitinol rods of 2 standard sizes - 60 and 80 mm. The size and curvature of the
bending of the rods is calculated from the average anatomical parameters characteristic of the lumbar
spine and lumbosacral junction.
In all groups, there were no statistically significant differences in preoperative values and in the control periods of observation of the VAS (for both the back and the lower limb), Oswestry and SF-36 between patients with nitinol and titanium rods (p> 0.05).
In both cases (rigid and dynamic stabilization), statistically significant changes were noted in the postoperative period (p <0.01). In both groups, in comparison with preoperative values, improvement was
observed in all control periods, which were highly statistically significant (p <0.01).
When studying the mobility in stabilized segment with dynamic nitinol rods, it is determined that the
mobility, which persists in 1 segment, averages 4.8Β°. This index is within the limits of measurement error
(up to 5Β°), however, when measuring mobility in two segments, the mobility is 9.6Β°.
Transpedicular fixation of the lumbosacral spine with the use of nitinol rods is an effective technology
that allows to keep movements in the lumbosacral spine in combination with a stable fixation. Further
study of this technology should continue, including with reference to deformations of the spine

Bearing in mind that the technique of surgical treatment of scoliosis and skills are high enough, iatrogenic spinal cord injury is still one of theΒ most feared complication of scoliosis surgery. It is well known that the function of the spinal cord may be estimated by combining somatosensoryΒ evoked potentials (SSEP) and motor evoked potentials (MEP). We have retrospectively evaluated the results of intraoperative neurophysiologicalΒ monitoring (IOM) in a large population of patients underwent surgical treatment of spinal deformity. Intraoperative neuromonitoringΒ SSEP and transcranial electrostimulation (TES) β MEP in conjunction with the assessment of the correct position of the screwsΒ was performed in 142 consecutive cases, i. e. all patients who had undergone surgical treatment of idiopathic (127 pts), congenital (10 pts)Β or neurogenic (5 pts) scoliosis. A neurophysiological βalarmβ was defined as a decrease in amplitude (uni- or bilateral) of at least 50 % forΒ SEPs and of 70 % for TES-MEP compared with baseline. Total intravenous anesthesia (TIVA) in 138 cases was achieved by infusion ofΒ propofol (8β16 mg / kg / h) and in 4 cases by halogenate anesthesia β sevoflurane (0.4β1.8 MAC).Β Seven patients (4.9 %) were reported intraoperative neurophysiological parameters significant changes that require action by the surgeonsΒ and anesthetists, with deterioration of ostoperative neurologic status in one case. Of these three cases, the amplitude drop SSEPs and TESMEPs-was due, to the pharmacological aspects of anesthetic management, in the other four cases β with surgical procedures (responseΒ halo-traction β 1 case, mechanical damage of sheath of the spinal cord by pliers Kerrison β 1case, overcorrection β 2 cases). In five casesΒ (3.5 %) required reposting of pedicle screws (1β2 levels). Only one patient (0.7 %) had a persistent postoperative neurological disorderΒ (neuropathic pain), respectively from a level of re-reposition of pedicle screws.ΠΠ΅ΡΠΌΠΎΡΡΡ Π½Π° ΡΠΎ, ΡΡΠΎ Π½Π° ΡΠ΅Π³ΠΎΠ΄Π½ΡΡΠ½ΠΈΠΉ Π΄Π΅Π½Ρ ΡΠ΅Ρ
