Mathematical Modeling of Indications for Reconstructive Surgery of the Hip Joints in Patients with Cerebral Palsy

Summary. Relevance. Early detection of hip pathology in patients with cerebral palsy is an effective way to prevent spastic dislocation.
 Objective: improve the diagnosis diseases joints through clinical and radiographic screening based on mathematical modeling.
 Materials Methods. The total number was 47 (86 joints). We carried out a radiographometric examination our own method using standard anteroposterior radiographs, which were used determine parameters joint. Mathematical modeling indications for reconstructive surgery logistic regression also performed.
 Results. model “probability surgical interventions” developed basis studied indicators factors influence.
 Conclusions. A acetabular angle (AA), neck-shaft (NSA), femoral torsion (FT), migration percentage (MP), gross motor function classification system (GMFCS) level, gait, age proposed; accuracy 90.6% valid establishing correct (the critical level >16.95 ̊ AA, >45 FT, > 141.63 NSA, >30 % MP, ≤11 years age).
