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.
