Intraoperatively, appropriate surgical strategies include long fusions with deformity correction for patients with large deformity and sagittal imbalance, and pelvic fixation for multilevel fusions with large curves, sagittal imbalance, and osteoporosis.
Occasionally the specimens retrieved from multilevel fusion included discs with low (0 3) degeneration scores (i.e. morphologically normal) at one level (Table 1) (The scoring system is described below).
Occasionally the specimens retrieved from multilevel fusion included discs with low (0 to 3 [see below for details of the scoring system]) histological scores (i.e. morphologically normal) at one level (Table 1).
This also applies to patients with indication for multilevel fusion.
6 Multilevel fusion procedures were shown to be more costly and associated with significantly more life-threatening complications and rehospitalizations than decompression alone, particularly within the 30 days postsurgery.
In this paper, a multilevel fusion scheme is proposed.
The multilevel fusion approach can be regarded as an extension to decision fusion (Figure 4).
This constitutes the reasoning why the multilevel fusion scheme consistently outperforms all the examined approaches.
The final decision is granted using the sum rule over the quantities y i. Figure 4 Multilevel fusion scheme.
This section presents the evaluation results of the different fusion schemes conducted at different levels of integration as well as the multilevel fusion scheme.
