Some evidence has suggested that THA leads to better functional outcome than HA [ 7]; however, there are some advantages of HA compared with THA such as reduced dislocation rate, less complex surgery, shorter operation time, less blood loss, and lower initial costs [ 12].
Zero-profile implant and PCB implant both achieved good clinical effects on the treatment of cervical spondylotic myelopathy, the two groups both saw bony union in operation segments, but Zero-profile implant has the advantages of easy operation, short operation time, less intraoperatve blood loss and less complications.
When this procedure is compared with the treatment of other maxillary sinusitis such as Caldwell-Luc surgery, ESS, it has some advantages such as lower complication rates, less blood loss and operation time, and lower cost.
Nine patients were excluded from the data analysis due to short operation time less than 8 h (3 patients in the GI group), hypoglycemia during GI infusion (1 patient in the GI group), and diabetes mellitus (3 patients in the control group and 2 patients in the GI group).
Bilateral pedicle screw fixation after MIS TLIF is generally accepted as a standard procedure for symptomatic spinal pathology treatment, [ 7– 9] but many clinical trials have reported positive outcomes (short operation time, less blood loss, and short hospital stay) associated with unilateral pedicle screw fixation after conventional TLIF and MIS TLIF [ 10– 10].
Reported advantages of HA over THR are reduced dislocation rates, less complex surgery, shorter operation times, less blood loss, and lower initial costs (Keating et al. 2005, van den Bekerom et al. 2010).
Based on this meta-analysis that compared ACDF and ACCF to treat two-adjacent-level CSM, ACDF has some advantages such as less blood loss, a shorter operation time, greater cervical lordosis in the total cervical and fused segments, a higher segmental height and less graft subsidence.
Time distribution study showed that shaking time accounted for less than 30% of entire operation time, while more than 50% of time was spent on relocation of the shake-and-catch system.
In our experiment, the operation time is less than 0.5 s due to the limited number of clusters (only three clusters).
However, some issues and potential pitfalls should be recognized such as high incidence rate of malignant ventricular arrhythmias, less induced infarct size, longer operation time (generally required 5 6 h), and larger trauma.
