Abstract
The object of the study: clinical effect of intramedullary blocking osteosynthesis of fractures of the bones of the extremities without reaming of the bone marrow canal. The problem to be solved: determination of the influence of surgical technology of intramedullary blocking osteosynthesis of bone fractures without reaming of the bone marrow canal on the qualitative and anatomical and functional results of treatment. Main scientific results. The term of fusion of bone fragments in complete groups (including all localizations) in the group of patients who underwent surgery with reaming of the bone marrow canal was 4.21±0.46 months, while in the group without reaming of the canal it was much shorter – 3.47±0.51 months Faster functional recovery of the limbs was also observed in cases that precluded bone marrow reaming – 96 % of good and 4 % satisfactory scores were obtained (80 % good and 20 % satisfactory in bone marrow reaming). The technology of closed intramedullary blocking osteosynthesis without reaming of the bone marrow can optimize the time of fusion of bone fragments and get 91 % good and 9 % satisfactory results. Its effectiveness is to reduce the number of satisfactory treatment results by 19 %, the absence of unsatisfactory and increase the share of good results by 23 %. The area of practical use of research results: clinics of traumatological profile of different levels, in which surgical treatment of fractures of the bones of the extremities are done. An innovative technological product: technology of closed intramedullary blocking osteosynthesis without reaming of the bone marrow canal. The area of application of an innovative technological product: clinical practice of using the technology of closed intramedullary blocking osteosynthesis without reaming of the bone marrow canal.
Highlights
The main advantage of this method is its low trauma, as the pin is inserted into the bone marrow canal far from the fracture site, which creates an opportunity not to damage the source of periosteal blood supply, which is important in the process of fracture consolidation [4, 5]
The use of the technology of closed intramedullary blocking osteosynthesis with reaming of the bone marrow canal in the treatment of diaphyseal fractures of the bones of the extremities in patients of group I led to 68 % good, 28 % satisfactory and 4 % unsatisfactory results
The technology of closed intramedullary blocking osteosynthesis without reaming of the bone marrow canal in patients of group II allowed to optimize the time of fusion of bone fragments and get 91 % good and 9 % satisfactory results
Summary
Stable osteosynthesis prevents further damage by soft tissue bone fragments and the progression of local and systemic inflammatory reactions, creates optimal conditions for reparative osteogenesis and improves the anatomical and functional results of fracture treatment [1]. The philosophy of surgical treatment using intramedullary osteosynthesis with blocking involves sTable fixation of bone fragments in an anatomically correct position without interfering with the fracture area, the possibility of dosed loads on the operated limb in the postoperative pe-. The main advantage of this method is its low trauma, as the pin is inserted into the bone marrow canal far from the fracture site, which creates an opportunity not to damage the source of periosteal blood supply, which is important in the process of fracture consolidation [4, 5]. Traumatic and minimally invasive closed-loop technology, minimal extraosseous circulatory disorders, preserved inner layer of periosteum, preserved interfracture hematoma, the possibility of static, compression or dynamic blocking have turned such osteosynthesis into a mechanism for fusion of bone fragments
