NOVEL J-PLATE FOR ANTERIOR PELVIC RING INJURIES OSTEOSYNTHESIS

The aim of the study was to evaluate the results of anterior pelvic ring fractures and acetabular fractures fixation with the specially designed plate by miniinvasive surgical approach. 
Materials and methods. 54 patients with anterior pelvic ring fractures and antrerior acetabular column admitted in Sklifosovsky Clinical and Research Institute for Emergency Care in the period from 2012 to 2020 year were analyzed. In 12 patients of the first group Judet-Letournel surgical approach was used. In 42 patients of the second group miniinvasive suprapubic and ilial surgical approach were used. In all patients novel J-plate was implanted. Mean operative time, mean blood loss, infectious complications were evaluated. Harris Hip Score for functional assessment after pelvic fractures was used for evaluation of long-term results.  
Results. Mean operative time in the first group was 181±25.4 min., mean blood loss amounted to 384±51.6 ml. Mean operative time in the first group was 98 ±21.5 min, blood loss - 183±59.8 ml. There were no infectious complications. The amount of good and excellent treatment results in the main group was 72%. Unsatisfied results amounted to 4%. 
 Conclusion. J-plate for pelvic injuries fixation is indicated in patients with anterior column and anterior wall acetabular fractures associated with contralateral pubic bone fracture or pubic symphysis rupture. Combination of ilial and suprpubic surgical approaches can be used in less than 2 weeks after trauma to minimize operation time and blood loss.
