A Comparative Evaluation between Fixation Techniques Using Lag Screws and Mini Plates in the Treatment of Parasymphysis Fracture.

Treatment of Parasymphysis Fracture

Abstract

Background: Aim: The objective of this study was to compare the results of lag screws and mini plates in treatment of parasymphysis fracture. Subjects and Methods: Forty patients of age group 20-45 yr old with clinical and radiological evidence of the traumatic injury to the parasymphysis were included in this study and were randomly divided in two groups. In group Atwo 2.5 mm lag screws were placed in 20 patients and in group Btwo 2.5 mm mini plates were placed in 20 patients. The statistical analysis was done by using SPSS 15. Results: The majority of patients in Group A, the time needed to complete the procedure ranges from 60 to 90 min (65%), while for the time range from 60 to 90 (55%) and 90 to 120 min (35%) in Group B. The difference in time required for completion of the procedures between the two groups was found to be statistically significant. In Group A, the duration of post-operative swelling varies as it is minimum for 5 days in 13 patients (65%) and maximum 15 days in 3 patients (15%). In Group B, swelling was present for minimum 5 days in 14 patients (70%) and maximum 15 days in 2 patients (10%) Conclusion: Although the sample size is less to reach to any conclusion, the results of our study suggest that the use of lag screws in the fixation of mandibular fractures can be a very demanding procedures as lag screw technique for Parasymphysis fracture provide several advantages over Mini plates.
