The Use of Electret In the Surgical Treatment of Children With Perthes Disease: Early Outcomes

Abstract

Purpose to evaluate the immediate results of the use of electret IMPLESO in the surgical treatment of children with Perthes' disease
 Matherials and methods.
 The study is based on the results of a comprehensive examination of 10 patients (10 hip joints) at an average age of 7.2 0.7 years. All children underwent a triple pelvic osteotomy, which was supplemented by a transfyseal implantation IMPLESO. In the postoperative period, all patients were evaluated for the severity of pain syndrome, amplitude of movements, ultrasound, radiometry of the main indicators of the structure and stability of the hip joint, CT and MRI of the hip joints.
 Results.
 All patients had the elimination of subluxation with the restoration of hip joint stability, a significant improvement in the shape of the femoral head with the appearance of its single bone contour, the volume of the bone part of the head increased by 15-35% from the original, and there was also a significant improvement in the shape of the cartilaginous model with the complete absence of a necrosis focus in the femoral head, close to the physiological position of labrum acetabulum.
 Conslusion.
 The use of IMPLESO in the surgical treatment of children with Perthes disease in Catterall III-IV groups and hip subluxation due to the anti-inflammatory effect makes it possible to stop pain syndrome and manifestations of synovitis early after surgery, to begin rehabilitation treatment. Apparently, the osteoreparative effect of the electrostatic electret field in its own version or in combination with anti-inflammatory provides an increase in the volume of newly formed bone tissue of the head with a decrease in the area of its defect of the epiphysis with differentiation of the initial elements of the trabecular pattern, in comparison with the homogeneous high-intensity structure of the femoral head.
