Results of Meta-analysis
After the application of the descriptors (MeSH Terms) in the databases
presented in the item Data sources and research strategy, 32 scientific
articles were found at the clinical level. After applying the article
selection filter for the last 10 years, 16 articles were found, of which
only 7 articles are strictly related to the objective of the present
study and entered the meta-analysis.
Table 3 presents the general data of each study analyzed, such as Type
of study, number of patients in each study, the types of fixation points
used, highlighting the priority for the analysis of 1-point fixation,
the main results of each study and the Follow up or Period of analysis
of each study. It also presents, in a manner described below, in Table
3, which were the main complications presented in some of the studies.
Two of the studies used biodegradable plates to compare fracture
stability with other plates.
Table 4 shows in quantitative terms the main complications in each
study, using the numeric codes Low = 1, Moderate = 2 and NO = 0, as well
as showing the success rates related to each study technique,
highlighting that in one study the technique was used by
three-dimensional photogrammetric analysis and in another study the
ultrasound-guided technique was used and titanium and biodegradable
plates were used.
After the statistical analysis to find out what the associations were
between the complications of the studies by the Chi-Square Test, the
results showed that there was no statistical difference between them,
with p = 0.305> 0.05 and R2 = 55.2%
(high association). In addition, using the Poisson Probability Test, it
was found that the probability of complications Low = 1, Moderate = 2
and NO = 0 was 0.65, 0.28 and 0.07, respectively (Table 5). This same
Table shows that the frequency of occurrence of NO-Complication was 5
(71.43%), Low-Complication was 1 (14.29%) and Moderate-Complication
was 1 (14.29%).
Figure 2 shows the graph with data on frequency, probability and
percentage of occurrence of complications.
