Degenerative changes at the adjacent levels were observed in 18 patients (35.3%).
Logit values were also considered in setting cut scores between adjacent levels (Papageorgiou 2009).
However, complications sometimes required subsequent surgery at the operated and adjacent levels.
In any event, very little risk difference exists between adjacent levels among the highest grades.
The fundamental property of multi-hop TTS is that it synchronizes nodes within two adjacent levels in one synchronization process.
Successful lumbar spinal surgery with osseous fusion results in altered biomechanics with hypermobility of adjacent levels, causing accelerated degenerative changes.
Balloon kyphoplasty and vertebroplasty are associated with a recurrent fracture risk in the adjacent levels after the surgical procedure.
The TTS halves the synchronization hops and effectively reduces the multi-hop synchronization error by synchronizing nodes of two adjacent levels.
Since electronic properties change with reduction in particle size to nanoscopic dimensions, the bandgaps and distance between adjacent levels within electron energy bands alter the chemical reaction.
Degenerative changes at the adjacent levels were observed in 18 patients (35.3%) (Fig. 4), whereas in the other 33 (64.7%), no signs of degeneration were found.
TDR at L4/5 was associated with small but significant increases in segmental ROM at the first cranial and caudal adjacent levels.
