Purpose. To study ultrastructural morphological changes of spasmodic femoris muscles and their dependence on morbidity terms.
Materials and methods. 12 children with cerebral palsy aged from 2 to 8 years underwent myotomy of adductor femoris muscles and neurotomy of obturator nerve. 2x2 cm pieces of spasmodic adductor femoris muscles were incised during the surgery and provided for further electronic microscopy study. Ultrathin slices (60–70 nm) were proceeded through Reynolds technique and studied under EM-400T.
Results. 3 general ultrastructural features of spasmodic muscles were identified during the study. Mild destructive changes-in children aged from 2 to 4 years, severe destructive changes in children aged from 5 to 6 years, severe outgrowth of connective tissue (muscle fibers were replaced by connective tissue) in children above 6 years of age. The long term presence of spasticity leads to permanent degradation of muscles, replacement of muscle fibers by connective tissue.
Conclusion. 1. Focal adductor femoris muscles spasticity in children with cerebral palsy leads to severe degradation of muscles and even replacement by connective tissue.
2. The severity of morphologic changes in spasmodic muscles depends on morbidity terms.
