Ilizarov method in the treatment of children with periarticular fractures

Introduction Periarticular injuries in children include types I and II fractures according to the Salter-Harris classification and metaphyseal fractures. In most cases, conservative treatment is an effective method, but in some cases, surgical treatment, including external fixation, is the method of choice. Purpose Discussion of the principles of using the Ilizarov apparatus in the treatment of children with periarticular fractures of various locations, its advantages and disadvantages. Materials and methods We present the principles and features of the Ilizarov surgical techniques for treatment of children with periarticular fractures of the distal humerus, femur, radius and tibia. Discussion The methods of osteosynthesis for pediatric periarticular fractures imply transphyseal introduction of fixators that have a potential threat of iatrogenic damage to the growth plate in contrast to external fixation which performance implies that transosseous elements do not injure the growth zone, providing stable fixation of bone fragments in combination with early functional recovery of the damaged segment which is a key advantage over other methods. Conclusion The use of the Ilizarov apparatus enables to achieve the desired result in the treatment of pediatric periarticular fractures and has a number of advantages over other methods of surgical treatment.

Limb Deformity Correction Using the Ortho SUV Frame

Background and Objective. Limb deformity in terms of length discrepancy, angular and rotational deformities are amenable to correction using the Ilizarov method. The corrections can be achieved using the Ortho SUV Frame (OSF), a computer assisted six axes external fixator. Previous studies have reported easier and more accurate deformity correction. In this study, we report on our initial experience and treatment outcomes in using this system. Materials and Methods. This study is a case series of patients where the Ilizarov circular frame was applied and which the deformity correction was carried out using the OSF. Success and accuracy in correction, length of time to correct, number of revisions needed and complications were gathered from a review of medical records. Results. Thirty limbs in twenty nine cases were included in this report. Seventy seven percent (23/30) of the deformities were due to previous trauma. The rest were due to Blounts, infection and tumor. Correction in eighty seven percent (26/30) were achieved using the turning schedule provided by the Ortho SUV application software. Three cases required surgical removal of soft tissue interposition before further correction using the software was achieved. One case with posterior translation underwent closed manipulation. In the end all planned deformity corrections were achieved. Complications included pin tract swelling and erythema in 13% and all resolved either with oral antibiotics alone or combined with surgical release of pin sites under local anesthesia. Conclusion. The Ortho SUV is an effective tool to carry out deformity corrections using the Ilizarov method.

Experimental Modeling of Combined and Sequential Use of Transosseous and Intramedullary Blocking Osteosynthesis

Background. The introduction of the combined and sequential application of transosseous and intramedullary blocked osteosynthesis in limb lengthening requires an experimental study of the features of distraction regenerate. For small animals (in particular rabbits), special models are required.Aims. To develop experimental models of sequential and combined use of transosseous and intramedullary osteosynthesis in limb lengthening and substantiate their effectiveness.Materials and methods. A comparative study was carried out on 30 rabbits of the Soviet Chinchilla breed. Experimental models of sequential (EM-1) and combined (EM-2) application of transosseous and intramedullary osteosynthesis with preservation of the apparatus during the fixation period to simulate blockage were studied in the main groups. For comparison, sequential (comparison model 1 – CM-1) and combined (comparison model 2 – CM-2) use of transosseous and intramedullary osteosynthesis with dismantling of the apparatus at the end of distraction were modeled. The control was a regenerate formed according to the classical Ilizarov method. Radiographs were performed in dynamics, CT and morphological studies – at the end of the fixation period.Results. It was noted that regenerates of the same type in structure were formed in the EM-1 and CM-1 groups, as in the EM-2 and CM-2 groups. With successive methods, the spindle-shaped form of the regenerate prevailed, the formation of a pronounced periosteal component was noted. Powerful cortical plates, according to morphological studies, are formed from the periosteal and intermediate zones. With combined techniques, the cortical plates are formed thinner and predominantly from the periosteal component, the shape of the regenerate is closer to fusiform. In the comparison groups, the total time of surgical interventions was 25–50 % longer, in 50 % of cases there was a loss of length or deformation of the regenerate.Conclusions. The developed models of sequential and combined use of transosseous and intramedullary osteosynthesis for limb lengthening with preservation of fixation with an apparatus to simulate blocking have proven to be reliable in terms of fixation and easy to use on small laboratory animals..

100 ANNIVERSARY FROM THE BIRTH OF GAVRIIL ILIZAROV - THE GENIAL SOVIET TRAUMATOLOGIST-ORTHOPEDIC (06/15/1921)

The article analyzes the unique personality of the XX century, the outstanding Soviet orthopedic surgeonGavriil Abramovich Ilizarov. The evolutionary process of the formation and development of the Ilizarov method in traumatology and orthopedics at the domestic and world level is shown. The undeniable advantages of the external fixation system developed by Ilizarov are revealed. The design of the Ilizarov compression-distraction apparatus is considered. Being familiar with G.A. Ilizarov, the author shares his memories about him, describes the biological and mechanical features of the influence on the bone and other tissues of the Ilizarov system, which has become a classic and internationally recognized in the treatment of patients with fractures, pathological conditions of the musculoskeletal system, congenital and post-traumatic orthopedic deformities of the limbs.

Dynamic Gait Parameters in Patients with Nonunion of the Tibia Following Treatment with the Ilizarov Method

INTRODUCTION: The purpose of this study was a comprehensive assessment of the dynamic parameters of gait in patients who underwent Ilizarov treatment for nonunion of the tibia. MATERIALS AND METHODS: The experimental group consisted of24 individuals treated with the Ilizarov method for nonunion of the tibia.The control group comprised31healthy individuals,matched for BMI,sex,and age.The dynamic gait parameters in patients and in the control group were measured with a Zebris pedobarographic platform. RESULTS: The treatment group and the control group showed statistically significant differences in terms of the following gait parameters:Maximum force 1NOL(non-operated-limb),Time maximum force1OL(operated-limb),Time maximum force 1 NOL,Maximum force 2NOL,Time maximum force 2OL,and Maximum force forefoot OL.Most of the evaluated gait parameters were bilaterally similar in patients group.The only significant differences between the operated and non-operated limb were seen in terms of Time maximum force 2and Maximum force forefoot. CONCLUSIONS: The most pronounced abnormalities in dynamic gait parameters were observed in the forefoot.The patients treated with the Ilizarov method did not achieve a complete normalization of dynamic gait parameters,as their gait parameters did not equal those measured in the control group.The Ilizarov method for the treatment of tibial nonunion helps restore a symmetrical distribution of gait parameter values between the affected limb and the healthy limb.Patients with tibial nonunion treated with the Ilizarov method continue to show some abnormalities in their dynamic gait parameters after treatment.

Bone transport over the nail vs Ilizarov method in the treatment of posttraumatic defects of the femur and tibia

Relevance. From the point of view of using the advantages of both external fixation and internal osteosynthesis, the method “Bone transport over the nail” (BTON) deserves attention.Intention: To compare the effectiveness of the BTON and Ilizarov method in the treatment of patients with post-traumatic defects of the long bones of the lower extremities.Methodology. We analyzed 24 BTON cases and 47 cases of defects replacement via the Ilizarov method. The analysis included patients with segmental defects of the tibia, femur and knee joint bone defects complicated by chronic osteomyelitis.Results and Discussion. The external fixation period in BTON group was 3 times less than in the comparison group, as was the external fixation index. In case of monolocal defect replacement, the external fixation period and external fixation index in the BTON group was 4 times less than in the Ilizarov defect replacement group. With bifocal replacement of the defect, the external fixation period was 2.5 times less, and the external fixation index was 2 times less. BTON interventions were associated with complications in 31 cases (129.2 %) vs 82 cases for the Ilizarov method (174.5 %). The most pronounced decrease (3 times) was noted for cases of transosseous elements inflammation.Conclusion. The “Bone transport over the nail” technique reduces the external fixation period by an average of 3 times. This facilitates management of the outpatient phase and reduces the number of complications, especially the pin-tract infection. Cable technique combined with an orthopedic hexapod allows bifocal replacement of extended defects of the distal femur and knee joint applying the apparatus only to the lower leg. Risks of jamming the transported bone fragments by the intramedullary nail are thus excluded. To avoid breaking the traction cable, only designated devices should be used.
