METHOD FOR CHOOSING SURGICAL APPROACH TO DYSPLASTIC COXARTHROSIS IN HIP REPLACEMENT Russian patent published in 2013 - IPC A61B5/488 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, orthopaedics. Preoperative electroneuromyography (ENMG) of gluteus medius muscle aims at detecting the conduction abnormality of fibular and tibial nerves and L5-S1 spinal roots. If observing the conduction abnormality of fibular and tibial nerves and/or L5-S1 spinal roots, femur medialisation and extremity elongation are required. Observing no conduction abnormality of fibular and tibial nerves and/or L5-S1 spinal roots and contractility reduction of the gluteus medius muscle more than by 60% as compared to an age norm requires femur medialisation and extremity elongation. Observing no conduction abnormality of fibular and tibial nerves and/or L5-S1 spinal roots and contractility reduction of the gluteus medius muscle more than by 60% and less as compared to an age norm requires femur lateralisation.

EFFECT: method enables reducing a risk of the postoperative complications ensured by considering the CNS condition additionally.
