Patella instabi instability in children: surgical treatment results

Abstract

Introduction. The main task of the surgical treatment of patients with latent form of the congenital pseudarthrosis of tibia (LFCPT) is the prevention of pathologic fracture and development of true pseudarthrosis. Purpose of the study: to evaluate the efficacy of preventive bone plasty in patients with LFCPT. Patients and methods. Treatment results for the period from 1980 to 2017 were studied in 38 children and adolescents (25 boys and 13 girls) aged from 9 months to 16 years, with the LFCPT. Transplantation of demineralized bone allografts onto the concave surface of bone was performed to all patients. Results. Follow up of surgical treatment results made up 1-16 years. In 6 months after operation bone graft projection showed active formation of bone tissue, in 12 months - the formation of compact bone tissue. Within the 4-years follow up pathological fractures were noted only in6 (15.8%) patients. Conclusion. Early indicated surgical intervention in children with LFCPT enables to prevent the pathological fracture in 84.2% of cases and preserve weight bearing ability.
