Opis:
Background. To evaluate the outcomes of transiliac cerclage with Dall-Miles cable in the internal fixation of the posterior complex in unstable pelvic ring fractures between January 1995 and December 2014. Material and methods. A study of 42 men injured at work with an average age of 35.2 years (range, 23 to 61) was conducted. The mechanisms of injury were traffic accidents in 25 cases (59.5%), crushing accidents in 12 cases (28.6%), and fall from height in 5 cases (11.9%). Thirty-six cases were polytraumatized patients (85.7%). The patients were evaluated using Majeed’s functional score and Matta’s radiological criteria. Results. The average follow-up time was 135.8 ± 45.6 months. The clinical outcomes were excellent in 17 cases (40.5%), good in 19 cases (45.2%), fair in 5 cases (11.9%), and poor in 1 case (2.4%). The radiological outcomes were satisfactory in 32 cases (76.2%) and unsatisfactory in 10 cases (23.8%). All fractures were healed. The sequelae were 3 cases (7.2%) of lower limb dysmetria and 3 cases (7.2%) of chronic neuropathic pain. Conclusion. The internal fixation of the sacroiliac complex by Dall-Miles cable cerclage reinforced with small fragment plates should be considered as an alternative method for minimally invasive osteosynthesis in selected cases of unstable pelvic ring fractures.

Opis:
This paper presents the results of numerical analysis aimed at determining the state of stresses and displacements of compression plate used in osteosynthesis of tibia, carried out by applying finite element method using the ANSYS program. The analysis took into account two variants of the osteosynthesis. Variant I included the osteosynthesis in which plate was attached directly to the bone, in variant II, the plate was moved away from the bones by about 5 mm. Biomechanical characteristics of the corrective osteotomy plate–tibia was determined for implants made of Ti-6Al-4V alloy. The boundary conditions adopted for the analysis reflect phenomena occurring in a real system. Based on the results of the analysis relative displacements and reduced stresses in various components were determined as a function of the applied load within the range of F = 500–1500 N. The maximum forces, both variant I and variant II determined during analysis, ensure that the generated stress does not exceed yield strength of the material and compressive strength of the bone, and do not exceed safety movement in the fracture gap. In addition, it was found that the locking of the compressive plate to the bone has a little effect on the distribution of displacements and stresses on the plate–tibia system in the case of a simple fracture.
