| Abstract | ||||
| Background Genu valgum is the most common reason for pediatric orthopedic consultations. Osteotomies are frequently unnecessary when hemiepiphysiodesis is performed on growing children with angular deformities. Aim To assess clinical and radiological outcomes of idiopathic genu valgum deformity treatment in the pediatric population with percutaneous retrograde transphyseal screw and evaluate its efficacy and safety. Patients and methods This prospective study involved 11 patients aged 8–14 years, encompassing both sexes, with genu valgum deformity of knee more than 20°. All patients were subjected to retrograde percutaneous transphyseal screw application. Results Mechanical lateral distal femoral angle was significantly higher after 3 months, after 6 months, after 9 months, and after 1 year than preoperative (P<0.001). The rate of correction was significantly higher after 6 months, after 9 months, and after 1 year than after 3 months (P<0.05). The rate of correction was significantly higher after 3 months and after 1 year in patients. The mean of improvement was 90.3±3.19%. The complication of this technique: rebound was defined after 6 months occurred in one (5%) patient. Flexion contraction occurred in two (10%) patients. Irritation of the medial collateral ligament occurred in two (10%) patients. Painful flexion occurred in one (5%) patient. Conclusion A safe and successful way for treating idiopathic genu valgum abnormalities in juvenile patients was the retrograde percutaneous transphyseal screw procedure. A faster rate of correction was seen in younger individuals, although the mechanical lateral distal femoral angle improved significantly and gradually with time in the research. | ||||
