Analysis of the literature data on the surgical treatment of feet deformities in children with cerebral palsy allowed determining of the first key pathogenesis aspects and management of surgical treatment. The main types of changes occurring in the feet under the influence of spastic disorders and the optimal methods of progressive deformities of feet surgical treatment were studied. The treatment management preference depends on intrapatient habits, age, the pattern of rescue, deformation gravity and mobility, level of the gross motor function (GMFCS). Various «soft tissue surgery» forms are effective provided sufficient deformation mobility for younger children group patients. The bone-cutting feet surgical measures are justified provided rigid deformations in more older children. A differentiated neurogenic feet deformities surgical treatment approach provides obtaining both early and long-term satisfactory treatment results.
The review of actual directions of optimization of surgical treatment of locomotor disorders in spastic forms of infantile cerebral palsy is presented. When choosing the tactics of the treatment for this category of patients, the following criteria should be taken into account: the degree of disturbances in motor activity associated with muscle tone disorders, the spasticity pattern, the presence of joint contractures, limb deformities, the level of intellectual development, the presence and severity of perceptual disorders. The implementation of simultaneous operations allows reducing the period of immobilization of the child and the period of temporary incapacity for work of parents and recommended for the treatment of patients with cerebral palsy at all levels of the Gross Motor Function Classification System (GMFCS). There are considered modern methods of surgical treatment of spastic instability of the hip when the choice of the method of correction of the acetabular component of instability depends on the degree of abnormalities of the anatomy of the acetabulum, mainly from the deficit of the bone covering of the head of the femur and the «slanting» of the roof of the acetabulum. In the treatment of contractures of knee joints in order to prevent сrush syndrome, the elongation of the medial group of tibial flexors is advisable to be used in conjunction with tonus-enhancing operations in the anterior group of femur muscles with their secondary weakness. When treating axial deformities of the knee joints and unequal length of the legs, it is important to observe the timeliness principle (during the active growth of the skeleton) with the use of minimally invasive surgical interventions - hemi and epiphysiodesis - to avoid the need for more traumatic interventions.
Introduction. Cerebral palsy (CP) is the main cause of childhood neurological disability in the world. Due to the fact that the prevalence of knee contractures in children with cerebral palsy occupies the 3rd place in the structure of orthopedic pathology of the lower extremities, this topic is least covered in the scientific periodicals. Material and methods. Findings from 40 patients of the main group, aged 7-12 and having cerebral palsy (CP), were studied retrospectively. They had knee flexion contractures with patella alta. Findings of goniometry and of Gillette FAQ were analyzed before and after surgery. The Spearman coefficient was used for the correlation analysis of goniometry parameters and surgical intervention effectiveness before surgery. 35 patients having no bilateral CP damage and other diseases leading to lower limb deformities were included into the reference group. X-ray examination and goniometry assessment of a healthy limb were made in patient’s lying position on his back with passive extension; plus goniometry in a standing position with shin active extension. Results. The median of deformation angles before and after surgery was 20° and 5°, respectively (p <0.05). Correction volume was 80%. The median of scores by the Gillette increased from 2 to 3 (p <0.05) after surgery. Assessment of the correlation between preoperative goniometry values and treatment efficacy values showed a significant moderate feedback (p <0.05). Conclusion. The stronger the deformity before surgery, the less chance for developing the standing-up function. The best result can be achieved when deformity is 10-25°. Normal values of passive extension by goniometry in a healthy knee for children aged 7-12 in a lying position are 6 ° hyper-extension (genu recurvatum) (± 2 °) and 12 ° hyper-extension (±3°) of a knee joint by lateral X-ray. Normal active extension in children aged 7-12 in a standing position is 3° hyper-extension (±2°). Smaller values of the tibiofemoral angle by goniometry in a standing position and maximun values for passive extension by X-ray and goniometry assessment may serve as clinical and radiological criteria of knee flexion contracture.
