An advanced method of bone tissue reconstruction in patients with osteoregeneration disorders (experience with clinical application of scaffold technologies) [ПЕРСПЕКТИВНЫЙ МЕТОД ВОССТАНОВЛЕНИЯ КОСТНОЙ ТКАНИ У ПОСТРАДАВШИХ С ТЯЖЕЛЫМИ НАРУШЕНИЯМИ ОСТЕОРЕГЕНЕРАЦИИ (ОПЫТ КЛИНИЧЕСКОГО ПРИМЕНЕНИЯ СКАФФОЛД-ТЕХНОЛОГИЙ)]

Nonunion and defects of bone tissue are the same complex of comparable pathological processes − impairment of reparative osteoregeneration of the diaphysis of the long bone. With objective of recovery of bone tissue and improvement in extremity function, the original technique for replacement of a bone defect in combination with internal fixation was offered. Materials and methods. We studied 119 patients with non-unions and 19 wounded persons with a bone defect in the diaphysis of the long bone. In the main group of patients, the bone defect was plastered with autobone and collagen hydrogel. Internal osteosynthesis was performed. In the control group, the bone tissue defect was restored by the method of G.A. Ilizarov. The result of treatment was assessed clinically, radiographically and by testing. Results. In the main group of patients with non-unions (61 people), the post-resection bone defect was restored in the mid-physiological terms of the segment bone fusion (mean time – 107.41 ± 41.29 days), which was 1.5 times better than the similar result of the control group (58 patients) – on average 170.45 ± 7.30 days. In the main group of wounded with post-traumatic bone defect (9 people), restoration of the integrity of the bone tissue was completed on average after 267.57 ± 32.61 days, which was 1.4 times faster than in the control group (10 people). According to the test results in the main group, a good effect of treatment was obtained by 8-24 % more, than in the control group. Conclusion. Collagen hydrogel is an effective matrix for the construction of a tissue-engineered structure when replacing a bone defect. The proposed algorithm for the treatment of patients with severe disorders of reparative osteoregeneration allows restoring the integrity of the bone and obtaining excellent and good treatment results. © 2021 The Charity Fund of Clinical Center of Miners' Health Protection.
