Purpose of study: to present the first experience of using the proposed method of pubic bones fixation and to determine the potentialities of its practical application. Patients and methods. During the period from 2016 to 2018 twenty patients (mean age 33.48 ± 10.85 years) with pelvic ring injuries were operated on. In all cases the pubic bones osteosynthesis with threaded pins was performed. In 15 (75%) cases the fractures (1980) were of type B1, in 5 (25%) - type C1 by Tile classification. In 14 (70%) patients the fractures of the pubic bones corresponded to Nakatani II, in 6 (30%) - Nakatani I. The quality of the reposition was assessed by Tornetta-Matta criteria and functional results were evaluated by Majeed score. The follow-up period varied from 6 to 24 months (14.2±5.6 months). Results. The average duration of fixation procedure of the pubic bone made up 10.4±4.2 min; the average volume of intraoperative blood loss in one pubic bone fixation was 6.3±1.4 ml. In all cases excellent and good reposition was achieved. In no one case the fixator migration was observed. Twelve months after surgery the functional results by Majeed score were assessed as excellent (15) and good (4) in 19 followed up patients. Conclusion. The use of the proposed method of the pubic bones fracture fixation with threaded pins can be recommended for patients with Nakatani I, II fresh fractures in the absence of soft tissue interposition. Rigid fixation of fragments with minimal risk of fixator migration provides conditions for early rehabilitation of patients and enables to achieve excellent and good functional results.
