Summary:

 Objective: to make assessment of clinical and laboratory indices in patients with deep periprosthetic infection and knee endoprosthesises aseptic instability. Material and Methods. 80 patients with septic and aseptic instability of knee endoprosthesises have been surveyed. All patients were subjected to comprehensive clinical and laboratory examination (intra-articular fuid cytology and microbiology testing, joint tissue histology testing, ELISA was employed for determining the levels of skeletal tissue remodeling markers). Results. The complete combination of several examination criteria specifc for knee periprosthetic infection was

Summary:

Aim: to perform comparative analysis of surgical outcomes of patients with extraarticular fractures of proximal femur with the use of various types of external osteosynthesis. Material and Methods. 169 patients with extaarticular fractures of proximal femur who underwent surgical interventions with various kinds of external osteosynthesis were the subject of the study. Results. Extra-cortical osteosynthesis with DHS-construction provided the restoration of anatomic and functional characteristics by 90.3±0.6% of normal values in the short-term and by 95.2±0.4% in the long-term postoperative period. The implantation of intramedullary constructs resulted in high percentage of positive short-term (92.1±0.6%) and long-term (96.7±0.75%) treatment outcomes. Conclusion. The use of intramedullary osteosynthesis

Intramedullary osteosynthesis in the treatment of humerus fracture consequences

Year: 2018, volume 14 Issue: №3 Pages: 523-529

Summary:

Aim: retrospective analysis of surgical treatment results of patients with the consequences of humerus fractures by locking intramedullary constructions. Material and Methods. 69 patients with ununited fractures and false joints of humerus diaphysis (39 females, 56.7±11.5 yrs (56.5%) and 30 males, 52.3±9.8 yrs (43.5%)) comprised observation group. In the course of surgical intervention they were treated by locking intramedullary rods to perform fragment anchorage, this including 12 patients (17%) with ununited humerus diaphysis fractures after conservative treatment, and 57 (83%) with false humerus joints. Clinical (limb functional restoration) and X-ray (integrity signs) methods were applied for the diagnostics and control of integrity restoration in bone structures; for the assessment of treatment outcomes we used standardized system of outcomes of locomotor fractures and their consequences (SOI-1). Results. Consolidation of the fracture up to 6 months postoperatively was observed in all patients with ununited humerus fractures, treatment outcomes by SOI were 85-94% of anatomic and physiological norm. The consolidation of humerus bone occurred in 50 patients with false joints with

Treatment of bone defects of tibia edge during external anchorage of fragments

Year: 2017, volume 13 Issue: №3 Pages: 727-731
Heading: Traumatology and Orthopedics Article type: Original article

Organization:
Summary:

The aim: to identify the efficiency of the improved technology of treatment of tibia marginal defects with the use of granular composite osteoplastic materials during external fixation of fragments. Material and Methods. The observation group was made up of 12 patients with the consequences of lower extremity traumas who had undergone osteosyn-thesis of fractures by an external fixation device with defect alloplasty We used clinical and ray-tracing testing methods and also standardized system of assessment of outcomes of bone fractures and their consequences to control the processes of restoration of bone structure integrity. Results. According to the standardized system of assessment of outcomes in 12-18 months in the course of the rehabilitation measures degree of restoration of anatomic functional indices was 92±5%. Bone density made up 91,3±0,54 HU (p<0,05) before surgery according to the Hounsfield scale, increase in the given parameter was observed in a month and a half after surgery up to 153,1 ±0,97 HU and in 3 months up to 162,7±0,78 HU. Conclusion. Application of granular composite osteoplastic materials for plastic surgery of tibia marginal defects during external fixation of fragments allow us to carry out anatomic reconstruction of the bone reducing surgery injury rate based on the absence of necessity of taking autogenous tissues from the other zones.

Summary:

Objective is to detect bone mineral density along the shin according to «Esperanto» levels by Hounsfield's scale. Materials and methods. The analysis of density modification in 25 patients with pseudoarthrosis of tibia with predominant localization in a lower one-third of bone has been carried out. Results. By means of computed tomography it has been revealed that the bone tissue density of the tibia in the process of false joint union when using the compressive variant of combined transosseous osteosynthesis has changed according to the regularity reproducing phase character of the accumulation of mineral substances in the bone. Conclution. The growth of mineral density of the bone tissue during treatment spreads in the directions from proximal and distal metaepiphyses to the zone of pseudoarthrosis knitting

Biomechanical evaluation of fixation degree of fragments by periosteal osteosynthesis

Year: 2010, volume 6 Issue: №3 Pages: 683-687

Summary:

Expansion of indications for surgery and plate osteosynthesis of long bones points to increased number of complications caused by instability of fragments, that can be associated in their turn with constructive features or iatrogenic factors. Insufficient rigidity of fragment fixation is due to incorrect technical treatment and wrong choice of fixator. Biomechanical parameters of periosteal fixation rigidity have been experimentally proved, depending on fixator lever
