[Etiology of hip dislocation in children with cerebral movement disorders and possibilities of conservative treatment using rotating and spreading plates and electrostimulation]. / Atiologie der Hüftverrenkung bei Kindern mit zerebraler Bewegungsstörung und Möglichkeiten konservativer Behandlung mit Dreh-, Spreizschalen und Elektrostimulation.

Dislocations of the hip associated with spastic paralysis are almost always found in severely disabled children. The onset is in infancy. Two methods, electrostimulation of the minor gluteal muscles and treatment with simple leg casts to correct the malposition, are described. Follow-up examinations showed that the treatment had had a positive effect on the hip condition in 33 of the 42 children treated with casts and 26 of the 32 children treated by electrotherapy. Electrotherapy is an innovation, since in the past it was considered contraindicated in these patients. However, it is based on the fact that the gluteal muscles do not normally show any spasticity. Irrespective of this, the treatment is long-term, and has to be continued for many years, a fact which makes greater demands on the cooperativeness of the family.
