The aim of the studyis to evaluate the efficiency of triple arthrodesis of foot and its effect on soft tissues blood supply at the surgical site during simultaneous correction of segment deformity in patients with cerebral palsy.Material and Methods. The present study reflects the authors’ experience of triple arthrodesis for correction and stabilization of foot multicomponent deformities of varying severity in 75 patients (136 feet) with cerebral palsy (IIIV level by Gross Motor Function Classification System (GMFCS)) treated in the Ilizarov center in the period from April 2012 to December 2016. The average age of the patients was 16.4±4.3 years (from 11 years 8 months to 43 years 3 months). All patients included into the study had severe arthrosis of hind and midfoot. The main option of foot fixation in this group of patients was internal fixation (elastic threaded wires, compression screws) together with plaster cast immobilization for 6–8 weeks. All patients underwent average of 4.59 surgical elements during a procedure as part of simultaneous multilevel interventions. The blood supply at the surgical site was evaluated by laser and high-frequency Doppler flowmetry before and after all stages of the surgery.Results.Long-term outcomes were evaluated at the average of 19 months after the surgery in 56 (74.7%) patients. 37 patients (66.1%) demonstrated good treatment outcomes and 19 patients (33.9%) — satisfactory outcomes. No unsatisfactory outcomes were observed. The clinical outcome of foot surgery was evaluated using the Angus-Cowell criteria. The obtained significant x-ray enhancement was maintained at the control stages of the follow up. Despite large simultaneous correction of foot deformity, there was no decrease in the parameters of microcirculatory blood supply of the skin, muscles and subcutaneous fat of the foot. The authors observed a stabilized or an increased perfusion of soft tissues.Conclusion.Triple arthrodesis for correction of foot deformities in patients with cerebral palsy and severe arthrosis in hind and midfoot is an efficient method which allows to correct and stabilize gained position of segments. The data of physiological research testify the sparing approach of such procedure and a possibility of an earlier weight-bearing on operated limb.

Introduction The article is a literature review focusing on reconstruction surgery for dislocated hips in children with cerebral palsy (CP). Material and methods Publications in Scopus, PubMed, RSCI indexed journals over the past 20 years were reviewed for hip dislocation in children with CP. Results and discussion The article discusses the prevalence of the orthopaedic complication of cerebral palsy, pathogenesis, diagnosis, indications to surgery, choice of surgical technique, early rehabilitation and long-term outcomes. A report made for the first educational meeting of the European Pediatric Orthopaedic Society held in Russia at the Ilizarov Center in 2021 was used for the contribution. Conclusion Surgical treatment is indicated for hip dislocation in children with CP using holistic approach and principles of single-event multilevel surgery that suggest hip reconstruction, addressing contractures and deformities of the subjacent segments and creating conditions for postoperative postural management. Standardized indications, patient selection and optimal time for intervention are to be carefully considered for the procedure with the use of customized orthopaedic implants and techniques.

To interpret the clinical gait analysis (CGA), it is necessary to associate changes in gait with clinical impairment and differentiate the primary deviations in the gait stereotype from compensatory adaptive changes. Purpose To assess the pathological elements of the locomotor profile according to video gait analysis and clinical examination of patients; to compare the abnormalities identified in gait kinematics with the probable clinical causes of these abnormalities. Materials and methods Clinical examination and assessment of the locomotor profile with video gait analysis (CGA) were performed in 46 children (92 limbs) with bilateral spastic types of cerebral palsy (25 boys, 21 girls). We used 6 Qualisys Oqus cameras and one AMTI dynamometric platform (Advanced Mechanical Technology Inc., Watertown, MA, USA) with passive marker video capture technology. The IOR model was used for installing markers. The patterns of the locomotor profile adopted by the Delphic Convention were analyzed. The assessment of diagnostic coincidences or discrepancies was evaluated as percentage rates. Results The portion of the pathological elements of the locomotor profile identified according to the video gait analysis and clinical examination of patients is presented in the tables. The positive ratio of the pathological elements of the locomotor profile identified according to the video gait analysis and clinical examination of patients averaged 66.7 %. The lowest error rate: when assessing the limitation of the range of motion of the ankle joint and hip joint there were 82.6% and 81.8% of positive results, respectively. Discussion Clinical gait analysis (CGA) is crucial in controversial situations regarding detorsion osteotomies in multilevel operations. Conclusions Muscle retraction is the main (primary) clinical sign leading to positional kinematic deviations in joints and segments. The limitation of the range of motion in the knee and ankle joints due to muscle retraction results in secondary contractures of these joints.
