INVESTIGATION OF THE NEURO-MUSCULAR SYSTEM IN PATIENTS WITH UNCOMPLICATED FRACTURES OF THE SPINE
The results of electroneuromyography of the neuromuscular system of the lower extremities in patients with uncomplicated fractures of the lower thoracic spine showed that during the rehabilitation period after surgery (1 year) the function of foot flexors remain fully intact. In 12-22% of cases in the early stages there are signs of motor deficit of foot extensor muscles, which disappears for half a year after surgery and again detected in 17% at 1 year after injury. In the early postoperative period electroneuromyography of peripheral nerves of the lower extremities revealed a mild subclinical neuropathy of n. tibialis in 24% of cases, n. peroneus - in 38%. A year after the operation a complete normalization of the tibial nerves functions occurred as the signs of «hidden» neuropathy of peroneal nerves were found in every third patient. In 2 weeks after the surgery at the level of the lumbosacral plexus the signs of hyperexcitability of motoneurons pool were reported in 50% of patients, which grew to half a year after surgery In a year at plexus level signs of deficiency of efferent fibers excitability, more expressed on L4-L5 level have been revealed. In the study of reflex activity of the lower extremities in 70-80% of patients with uncomplicated spine fractures bilateral suprasegmental violations by type of increased excitability of afferent fibers at the level L5-S1 were registered.
